Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop a cryogenic liquid hydrogen storage and delivery solution that can achieve high hydrogen mass fraction and a low boil off rate. Demonstrate that the cryogenic liquid hydrogen storage system improves endurance, range, and continuous payload power in an unmanned aerial system (UAS).

Description:

Hydrogen fuel-cell-powered air systems are becoming more prevalent in aviation [Refs 1-4]. Although compressed gaseous hydrogen has traditionally been employed to power these systems, cryogenic liquid hydrogen has recently started gaining traction [Refs 5-8]. Overall, liquid hydrogen storage provides added benefits such as reduced weight and volume compared to gaseous hydrogen storage, but there are still challenges to air vehicle integration and long-term use due to the extreme low temperature and other properties of liquefied hydrogen [Refs 9-10].

This STTR topic is seeking a liquid hydrogen storage and delivery solution that achieves high performance metrics while also maintaining longevity, safety, and usability for US Navy and US Marine Corps UASs. The performance metrics of interest for the delivered solution include a gravimetric hydrogen storage efficiency = 40% and volumetric hydrogen storage density of > 40 g/L. The integrated solution must also maintain a hydrogen boil-off rate of 100 fill cycles. The storage solution and filling procedure must also meet standard safety requirements such as those called out in DOC 06/02/E on the H2 Tools website [Ref 11].

Additionally, consideration should be made for integration into a range of UAS sizes from a Group 2 to Group 5. This shall include considerations for fuel level monitoring and sloshing effects during flights, as well as meeting necessary environmental (basic hot and basic cold), shock, and vibration requirements called out in MIL-STD-810-H [Ref 12]. Ability to demonstrate that the new cryogenic liquid hydrogen delivery system can manage and mitigate thermal loads of UAS mission systems is of particular interest. Finally, cryo-compressed hydrogen solutions will also be considered if it meets the key performance parameters outlined here.

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop Mid-Wave Infrared/Long-Wave Infrared (MWIR/LWIR) nonlinear optical (NLO) dyes embedded in sol-gel glass operating as an Optical Power Limiter that protects optical sensors from damage caused by high-intensity light by reducing transmittance at high input power levels such as from frequency agile lasers and dazzlers.

Description:

The proliferation of commercial, visible, and infrared wavelength laser systems is increasingly becoming a threat to our warfighters, which drives the need for further research and development for electro-optical/infrared (EO/IR) sensor. Current fielded sensor protection equipment is limited to fixed wavelength filters. However, broad band filters that are designed to circumvent multiwavelength laser threats are plagued by low transmittance, which degrades the sensitivity and performance of the sensor. Future warfighter threats include frequency agile lasers and dazzlers which have the potential of defeating fixed filters. Self-activating (passive) devices, where protection is activated by the incoming radiation (optical limiters), are the best approach to counter frequency agile and short pulse laser threats. The current state of the art of optical limiters are hampered by off-state low transmittance, low laser damage threshold, high activation laser threshold, and narrow field-of-view (FOV) and bandwidth. In addition, a sensor’s size, weight, and complexity greatly affect the user’s acceptance as a potential optical-limiting device. A sensor protection device is generally designed as an insert, an add-on, or replacement to the optical system. The optical limiter must be designed not to impact the sensor’s FOV and optical transmission. Currently available systems are very bulky and narrow band in their protection.

This SBIR topic solicits new, innovative NLO dyes embedded in sol-gel glass to provide sensor protection from frequency-agile laser and dazzlers operating in the MWIR/LWIR spectrum. The proposed NLO dyes embedded in sol-gel glass should allow ample transmission of ambient MWIR/LWIR light and be of high optical quality so as not to significantly degrade sensor performance. It should have a fast response time when exposed to dangerous fluence levels, sufficient to react to and block incident laser pulses to a high optical density. The dyes should be capable of changing from a high transmission state to a very low transmission state within sufficiently short time to block nearly all of the light contained in a light pulse emitted from frequency agile lasers and dazzlers . When harmful radiation is no longer incident, it must recover to a high transmission state in a short amount of time so that the sensor’s optics are not interrupted or significantly degraded after exposure. The proposal should discuss in detail the spectral transmittance in the attenuating state, activation threshold, response time, optical density in the attenuating state, and recovery time of the technology, the electric and other parameters of the excited state to be taken for measurements, excimer formation as well as any other important technical details.

The NLO dyes embedded in sol-gel glass critical requirements are:

1) Wavelengths – threshold MWIR 3 to 5 micron goal MWIR/LWIR 3 to 12 microns;

2) Response time: 3) Recovery time: 4) Low-intensity transparency is > 50%

5) For light intensity or fluence above the limiting threshold (LT), the attenuation is > 20dB

6) The Damage threshold (DT) is at least 10 times larger than that of the nonlinear optical material used

7) The fluence limiting threshold (LT) is below 500 milli-joules/cm^2/pulse

8) Multiple use without performance degradation exceeds 10,000 pulses

9) Wide acceptance and protection angles

10) Testing should be performed using f-number optics no greater than f/10, unless a higher f-number is required by a specific application

11) Dynamic range (~120 dB)

12) Rapid response time (~20 us)

13) Optical limiting threshold of 6.5 W / cm2 at room temperature.

Use of government materials, equipment, data, or facilities will not be offered and will not be required. If the technology is capable of exceeding any of the above requirements, the proposal should note this as well. Likewise, the proposal should note any limitations inherent to the proposed technology.

New and innovative material solutions may be proposed to provide new options for sol-gel glass production. Potential candidates include but are not limited to vanadium dioxide, use of commercially available or novel silanes and solvents. Processing approaches could include methods to control the rate of curing of the glass and the type, material, and shape of container used for the cure, as well as the cure temperature.

The goal is to develop a process that can make larger optical elements more reliably. Well established materials and processes may be proposed with a focus on improving the manufacturability, producibility, and reliability for current and next generation optical elements. Increasing size, manufacturing yield, and reducing cost while at the same time reducing manufacturing variability is desired. Proposers must have experience in the production of dye containing sol-gel glasses.

A second requirement of the optical elements are dyes which have the required optical transmittance/absorbance properties while being compatible with the sol-gel materials and production methods and are reliably available from domestic sources. This is currently a challenge. The performer will be required to identify suitable dyes for the optical elements and to design synthetic approaches to any dyes that are not commercially available from reliable domestic sources. The performer will synthesize any required dyes not commercially available from domestic sources in amounts exceeding 10 grams by the end of Phase II and have the capability to produce the dye(s) at batch sizes of at least 10 grams going forward or to work with another domestic producer to do so, or both. Proposers should have documented experience in the design, synthesis, and production of novel and existing absorbing and fluorescing dyes in the infrared regions of the spectrum and must have demonstrated the ability to reliably and reproducibly synthesize, purify, and characterize light-absorbing dyes at greater than 10-gram batch size. The proposal should clearly identify the current state of the art of the sol-gel and dyes of interest including both technical and manufacturing readiness and how the proposed work will advance readiness for the proposed optical elements.

Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. owned and operated with no foreign influence as defined by 32 U.S.C. § 2004.20 et seq., National Industrial Security Program Executive Agent and Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA) formerly Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances. This will allow contractor personnel to perform on advanced phases of this project as set forth by DCSA and NAVAIR in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material during the advanced phases of this contract IAW the National Industrial Security Program Operating Manual (NISPOM), which can be found at Title 32, Part 2004.20 of the Code of Federal Regulations.

Flexible Printed Thermoelectric Cooling Film - STTR Topic DON26TZ01-NV013

Funding Amount:

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop a low-cost and lightweight thermoelectric cooling film that could be used to cool the warfighter (small scale) or surfaces on military platforms (larger scale) using printed organic semiconductors. The flexible cooling films should have a bending radius of less than one inch to easily wrap around pipes, wrists, and ankles, and be able to conform to complex curvatures on larger surfaces.

Description:

Thermoelectric cooling devices based on narrow bandgap semiconductors such as bismuth telluride are commercially available. They are solid state devices and thus do not have the large footprint and moving parts associated with vapor compression refrigeration systems; however, they operate with lower efficiency. They are well-suited for cooling small flat surfaces where one is more concerned with the form factor than efficiency. For many practical applications, these square ceramic tile thermoelectric devices are heavy and too rigid, and do not offer conformal contact to curved surfaces.

Over the past fifteen years, a lot of progress has been made on organic thermoelectric materials. Though the thermoelectric figure of merit (ZT) has not caught up to that of bismuth telluride and other inorganic materials, the potential to make low-cost, lightweight, and flexible devices has opened a new application space for thermoelectric cooling where flexibility and large-area conformal contact are prioritized over efficiency. For instance, lightweight headbands and wristbands only need to remove a small amount of heat to provide significant cooling sensation to the user. Likewise, there are diffuse, large surface area applications with similar cooling needs. Prior research was summarized in a recent review article by Segalman [Ref 1].

The conducting polymer Poly(3,4-ethylenedioxythiophene) [PEDOT] was identified as a strong candidate for the p-type leg in the p-n device, but device performance has been limited by the lack of suitable n-type materials. The organic electronics community has long wrestled with n-type materials due to potential oxidation of the electron carriers. A number of inherently stable and high performing n-type polymers have recently been developed [Ref 2] that should complement the available p-type materials and enable significantly improved thermoelectric cooling device performance. New device designs obtainable with simple fabrication must be developed to take advantage of the anisotropic thermal conductance and charge transport in these materials, which is typically maximized in-plane and along the polymer molecular backbones, such that measured thin film behaviors successfully translate into device performance. A number of design and fabrication strategies have been demonstrated but much more innovation is possible [Ref 1]. It is an appropriate time to develop lightweight, flexible thermoelectric cooling devices for these niche applications.

This STTR topic is for low-cost, lightweight, and flexible thermoelectrics for personal cooling as well as for large area applications.

The flexible cooling films should have a bending radius of less than one inch to easily wrap around pipes, wrists, and ankles, and be able to conform to complex curvatures on larger surfaces. The stated applications are near-ambient temperatures though the conjugated polymers should be able to handle temperatures up to 200°C. Composite approaches that are appropriate are welcome. This topic is not soliciting a fabric-based solution.

Funding Amount:

Est. $2 Million.

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop and demonstrate a pilot-scale manufacturing process for producing high purity tetrakis(dimethylamido)zirconium(IV) (TDMAZ), tetrakis(dimethylamido)hafnium(IV) (TDMAH) and related metal dimethylamide compounds, with a targeted annual production capacity exceeding 6,000 kg of TDMAZ.

Description:

The Department of the Navy is seeking a domestic source of critical chemical feedstocks including TDMAZ, TDMAH, and other metal dimethylamide compounds. These chemical feedstocks can be used as metal organic precursors for atomic layer deposition (ALD), chemical vapor deposition (CVD), and chemical vapor infiltration (CVI) of metal oxides, nitrides, and carbonitrides used in microelectronics and ceramic manufacturing [Refs 1-3]. While TDMAZ is a vital ceramic precursor for the electronics and semiconducting industry, this effort will also support the use of TDMAZ for the preparation of metal nitrides and carbonitrides for ceramics and ceramic matrix composites.

This SBIR topic seeks to establish a domestic manufacturing capability for the production of > 6,000 kg/year of TDMAZ. Synthesis of TDMAZ and other metal dimethylamides often involves pyrophoric and air/water sensitive reagents, and the proper storage and handling of these reagents is crucial for the development of a cost-effective and large-scale manufacturing process. Along with the production volumes mentioned above, the metal precursors must have a purity > 99% and a target retail price of < $4,000/kg of TDMAZ, preferably < $2,500/kg. The proposed manufacturing facility must be located in the United States or US territories, and the company owning and operating this manufacturing facility must be wholly US owned and based.

Objective:

Develop medical products that are interoperable and compatible across humans and dogs to meet the health needs of both human warfighters and military working dogs.

Description:

Military working dogs (MWDs) are critical to national security, serving as force multipliers by enhancing the lethality and survivability of their teams through their unique senses, agility, and autonomy. Providing effective medical care for MWDs is critical but imposes significant challenges. Not all human medical products work for canines (K-9s), who sometimes require separate, specialized veterinary products. MWD handlers must therefore carry extra medical equipment to provide emergency care for their K-9 partner, exacerbating equipment loads and impeding operational capacity. Specialized equipment also expands medical materiel requirements and dependence on the less-resourced veterinary market, encumbering acquisition and sustainment activities.

Medical technologies that are interoperable and compatible across humans and dogs can address unmet needs of valuable MWDs while lessening the burden on medics, logisticians, and other contributors to force health protection. Species-interoperable medical technologies, particularly those supporting acute and tactical care, will improve lifesaving medical care for these MWDs while mitigating logistical and operational burdens of treating both human and K-9 warfighters.

The Defense Advanced Research Projects Agency (DARPA) is soliciting medical technologies that are interoperable and compatible across humans and dogs. Technologies of greatest interest allow for the replacement of existing products in medical sets with interoperable products, reducing the total amount of medical supplies—expanding capability without expanding the kits. Examples of specific technologies of interest include, but are not limited to:

Filters for donor plasma capable of removing cross-reactive antigens that impede compatibility across species;

Universal synthetic plasma designed with all necessary functional components for transfusion;

Sensors and form-factors that enable physiological monitoring (e.g., core body temperature and blood pressure) or triage in both humans and dogs;

Medical devices (e.g., splints, backboards, tourniquets, mechanical ventilators) designed to be rapidly adjustable at point of care for flexible use across anatomies;

Interoperable medical countermeasures (MCMs) and form-agnostic personal protective equipment to mitigate or protect against chemical, biological, radiological, and nuclear threats; and

Delivery mechanisms that can modulate dosing, including through excipients or combination devices (e.g., autoinjectors), to enable universal use of pharmaceuticals and MCMs.

The aim of the solicitation is to create a demonstrative prototype that can quickly progress to pre-clinical or clinical testing during a contracted SBIR Phase II period of performance (PoP). Research that merely tests existing products, including collection of data to titrate dosages or support label expansion of a marketed product to an additional species, is unlikely to achieve the degree of technical innovation a successful proposal should demonstrate. New drug discovery is discouraged but may be considered in particularly compelling cases. Products enabled by proposed research should feasibly be safe and effective in both humans and canines—to be verified in future trials—for use cases where no single existing product serves both patient sets. Technologies of interest should be capable of achieving substantially equivalent or superior performance in humans compared to currently approved options.

An initial white paper describing the technical approach is required and will be evaluated. If DARPA selects a white paper for further evaluation, the Government will issue an invitation to submit a full proposal. The technical white paper should include an overview of the proposed concept with details to support feasibility. The overview should address the bullets below, which are listed in order of importance:

Proposed concept: Describe the proposed research and medical product. Outline the design and operation of the main components that are being proposed for development and mode(s) of action. Use clear calculations, preliminary data, or mechanistic justifications to support feasibility of the proposed concept.

Concept of employment: Identify how the proposed product could be employed. Provide details on the intended use, indication, and effect, and the prevalence and impact of the addressed medical condition. What benefits, including new capabilities or improved metrics, does the proposed solution provide compared to current commercial off-the-shelf (COTS) options (e.g., commercially available human- or canine-specific products)?

Path to market: Identify relevant predicate or otherwise established products that have been approved, licensed, authorized, or cleared by the U.S. Food and Drug Administration (FDA) or other relevant regulatory authority. Provide a general plan or strategy for securing market access and ensuring regulatory compliance for both humans and canines if the proposed technology is successful and shown to be safe and effective. For any special FDA programs noted (e.g., Breakthrough Device designation, 513(g)), ensure that the white paper describes how the medical product meets the program requirements.

Scalability: Provide a brief analysis of the feasibility of scaling the technology across both the DoW and industry. Are the achievable production costs low enough to merit widespread adoption, especially if alternative human- or canine-specific products are available?

Funding Amount:

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop a modeling and simulation (M&S) application for generating high-fidelity, thermally-attributed virtual electro-optic and infrared (EO/IR) object models—specifically weather-explicit 3D clouds and/or debris fields—for integration into real-time scene generation systems.

Description:

Developmental and Operational Testing (DT/OT) of Missile Warning Systems (MWS), Infrared Countermeasures (IRCM), and Intelligence, Surveillance, and Reconnaissance (ISR) systems are currently limited to in-flight tests or the use of recorded flight video in digital system models (DSM). These methods do not adequately replicate the complexity of battlefield, industrial, and urban environments, especially under high-clutter, thermally dynamic conditions.

To enhance system survivability and test realism, validated synthetic 3D scene models are required to represent high-fidelity thermal environments unachievable through traditional Test & Evaluation (T&E) methods. These models enable more effective assessment of performance and operational effectiveness across a range of mission scenarios.

The Navy’s EO/IR Direct Inject (EOIRDI) initiative employs the Synchronized Kilohertz Injection Projection (SKIP) scene generation system to support hardware-in-the-loop engagements.

SKIP is capable of operating across multiple formats:

2k x 2k at 60 Hz

512 x 512 at 500 Hz

320 x 320 at 1kHz

To fully utilize SKIP's capabilities, synthetic test engagements must be developed to match specific system-under-test (SUT) frame rates and resolution formats, incorporating unique geographic locations and weather conditions.

This topic seeks a M&S application for generating high-fidelity, thermally-attributed virtual EO/IR object models—specifically weather-explicit 3D clouds and/or debris fields—for integration into real-time scene generation systems.

The tool must enable validated six degrees of freedom (6-DOF) physics-based simulations to support live, virtual, and constructive (LVC)-based survivability assessments of modern threat engagement systems in cluttered battlefield environments involving air-to-air missiles (AAM) and surface-to-air (SAM) threats.

The solution must support scene generation at real-time frame rates (60 Hz, 500 Hz, 1 kHz) using the EO/IR rendering framework built on OpenSceneGraph (OSG) and Virtual Planet Builder (VPB). Models must include optical, thermal, and physical attributes—such as spectral absorption, emissivity, and reflectivity—across the MWIR band (3.0–5.0 microns), with scalability to 0.2–20.0 microns. The system will enable creation, rendering, and validation of thermally accurate clutter (clouds/debris) varying by temperature, atmospheric composition, and precipitation to support enhanced DT/OT of threat detection and survivability systems.

Funding Amount:

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Research, develop, and evaluate robotic system methodologies for automating or augmenting the assembly of Expeditionary Airfield (EAF) matting to enhance operational efficiency.

Description:

EAFs serve as vital shore-based aviation support systems that enable the rapid deployment and recovery of military aircraft in environments lacking established infrastructure. Currently, assembling EAF matting is a manual process carried out by Marines—a task that is physically demanding, labor-intensive, and exposes personnel to potential hazards.

Developing a robotic system capable of assisting with or fully automating this assembly process would offer significant operational benefits: increasing efficiency, reducing risk to personnel, and enabling Marines to focus on higher-priority mission objectives. The level of autonomy should allow for the robots to navigate and control without human assistance, which includes obstacle avoidance, path planning, and grasping. Such a solution would improve overall force readiness and effectiveness in austere and time-critical operational scenarios.

The approach includes defining and developing a viable system concept, while investigating various robotic configurations—such as mobile manipulators and assistive technologies—for their effectiveness in EAF mat handling, alignment, and interconnection across diverse and austere terrains.

The research will evaluate the proposed system's capacity to:

Traverse and operate on uneven or unstable surfaces

Manipulate and position heavy EAF mat sections with precision

Endure harsh environmental and operational conditions

Integrate seamlessly with current EAF deployment procedures

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Design, develop, and demonstrate an innovative airborne radio system with a reduction compared to current airborne radios. The solution will incorporate a Modular Open Systems Approach (MOSA) and Model-Based Systems Engineering (MBSE) methodologies to ensure seamless integration across Navy and Marine Corps platforms including fixed wing, rotary wing and UAV aircraft.

Description:

The Navy seeks an innovative, open-architecture airborne radio system optimized for a minimal Size, Weight, and Power (SWaP) to ensure seamless integration across a wide range of NAVAIR platforms, such as the SH-60, F/A-18, E-2D, and MQ-4C.This system will leverage a MOSA to ensure future adaptability and significantly reduce the cost and complexity of radio upgrades. The goal is to provide a pathway for future modifications without impacting existing platform infrastructure.

Developing aircraft radio systems presents significant challenges due to stringent SWaP constraints, harsh environmental conditions, and demanding Electromagnetic Compatibility (EMC) standards. Equally critical is robust cybersecurity, requiring adherence to standards like NIST SP 800-53 and the integration of security measures throughout the system design lifecycle.

The objective of this SBIR topic is to design, develop, and demonstrate an innovative airborne radio system optimized for SWaP efficiency. The system must satisfy current security and operational demands, while providing a modular, scalable architecture that accommodates future technology upgrades and supports evolving communication waveforms.

An open architecture is also critical to sustain radio systems through their lifecycle. The MOSA leverages a robust ecosystem of established standards, including Sensor Open Systems Architecture (SOSA) and Modular Open RF Architecture (MORA) that enable modularity and interoperability. Additionally, applying an MBSE to radio system design will enhance system understanding, enable early defect detection and improve documentation.

Additionally, the resulting radio system architecture should adhere to the following technical goals:

Fit within the tight size constraints of two VNX+ standard cards (78 mm x 89 mm x 19 mm each). Note that a VNX+ power supply, backplane and I/O connectors will be external to the solution.

Support two separate Transmit and Receive RF channels. One RF channel capable of 30MHz to 6HGz operating frequency and the other capable of supporting 30MHz to 31GHz

Support at least 60MHz instantaneous bandwidth

Support transmit power amplifier capable of reliably delivering an average 25 Watts of RF power on transmit channel 1 and 1 Watt of RF power on transmit channel 2

Interoperability with MORA devices for control and I/Q data sharing

Capable of Digital Pre Distortion (DPD)

Capable of programmable RF waveforms including VHF/UHF communications waveforms including AM/FM, Air Traffic Control (ATC), Public Safety, Have Quick II, SATURN, SINCGARS, DAMA, MUOS, JPALS, and Automatic Direction Finding (ADF), Link-16

Capable of 1024-QAM OFDM modulation with 1000 subcarriers

Funding Amount:

Est. $2 Million.

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop a passive Structural Health Monitoring (SHM) system to identify, locate, and characterize the severity of defects and cracks due to fatigue loading or impacts based on novel or advanced technologies with a basis in physics and avoiding qualitative assumptions.

Description:

The Navy seeks an effective passive Structural Health Monitoring (SHM) system for Navy ship hulls and other structures that can monitor defects, such as crack growth from fatigue or impacts, and provide actionable information about the severity of the defect in an automated manner, i.e., in real time. Such fatigue cracks develop and grow in Navy ship hull welds and plating from cyclical life-cycle stresses and event-driven forces from severe sea states, collisions, and groundings.

The U.S. Navy and other navies around the world have installed SHM systems to monitor hull structural health but almost all are based on using strain gauges to monitor stresses on the hull and inferring crack growth based on fatigue life calculations. For example, the Military Sealift Command (MSC) has worked with the American Bureau of Shipping (ABS) and installed SHM systems consisting of strain gauges and accelerometers on several ships in the T-EPF class, which monitor hull deflection and dynamic movement due to the ship’s loading and the sea states encountered. The data from these sensors is being fed into a digital twin model developed to calculate structural stresses for managing vessel survivability and to minimize operating risk.

There have been some attempts to develop fiber optics sensors to measure strain or Acoustic Emission (AE) sensors to monitor fatigue cracks directly. These approaches have seen varying levels of success, yet, better systems are needed. There may even be some applications for LiDAR use to improve success probability. The Navy is particularly interested in locating and characterizing the severity or criticality of a defect if one is detected. Currently there is not a system available on the commercial market.

The Navy’s need for such hull monitoring capability has become more important with the introduction of high-speed and catamaran vessels, which are more prone to hull cracking due to the designs of the ships, materials of the hull, and stresses experienced in high seas. An ideal system would be capable of monitoring large areas of the ship’s hull with sensing devices that provide cost effective coverage with the following capabilities:

Detect and identify the location of crack growth signals in the hull if they exist in the presence of ship’s background noise without producing false positives or negatives.

Produce results in an automated manner, i.e., real time, so they are immediately available to the operating crew.

Provide insight as to the severity of the crack growth considering the complex geometries found in hull structures with varying thicknesses and stiffeners.

The Navy would benefit from understanding structural risks in real time with the goal of minimizing the possibility of incurring structural damage at sea. The SHM system the Navy needs should provide meaningful information on ship structural health and reduce inspection and maintenance costs during repair availabilities by identifying areas of concern or damage in advance.

Objective:

Develop a high-gain, low-frequency vertical line array of vector sensors capable of long-range passive detection and enhanced signal processing, deployable in an A-size form factor.

Description:

To enhance anti-submarine warfare (ASW) detection and directional sensitivity in deep waters, the U.S. Navy requires a high-gain directional, low-frequency.

The objective is to develop a high-gain, low-frequency vertical line array of vector sensors capable of long-range passive detection and enhanced signal processing, deployable in an A-size form factor.

The system will be deployed from Navy Maritime Patrol and Reconnaissance Aircraft, have capability across multiple operational environments, and will utilize the necessarily varied hardware configurations, passive processing, and frequency characteristics to consistently achieve critical ASW metrics.

The sonobuoy must support deep-water tactical operations. Deployment depths up to 1000’ and 8 hours of life is required. The array design will provide 17 dB of gain at the design frequency in a three-dimensional isotropic ambient noise field as a minimum. The maximum saturation level will be 128 dB/µPa at 100 Hz with a total dynamic range of 96 dB. The sensor solution must be low power and fit within an "A" size sonobuoy (4.875-inch diameter x 36-inch length, weight under 40 pounds). Acoustic data sent to the aircraft from each vector sensor shall consist of Omni, Sine, and Cosine data. The communications link must comply with NATO's STANAG 4718.

Funding Amount:

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Develop and transition a portable induction welding system capable of in-situ repair of thermoplastic composite components on naval aviation platforms enabling rapid, field-ready maintenance capabilities for next-generation naval aircraft.

Description:

Modern aviation platforms are increasingly using high-performance thermoplastic composites such as PAEK, PEEK, PPS, or PEI reinforced with Carbon Fiber for structural and semi-structural components. Their attractiveness is due to their superior damage tolerance, impact, and ability to be reworked for repair. Unlike traditional thermoset composites, which can only be repaired by bonded patches or bolted panels, thermoplastic composites can also be repaired by welding, which restores strength without the need to remove additional material. However, currently available welding systems have a large footprint and are available mostly with OEM and only suited for deployment at the Depots. Thus, without field deployable technofixes, repairs will result in long downtime for repair and likely higher scrap rates.

This STTR topic seeks to leverage the research expertise of academic or government labs in thermoplastic processing and electromagnetic heating to partner with a small business in designing a rugged, portable induction welding system that can be deployed shipboard and/or in Aircraft Intermediate Maintenance Detachments.

The proposed system should: (1) be capable of welding aerospace-grade thermoplastics (at temperatures up to 400°C); (2) be lightweight and field operable, including on aircraft carriers; (3) be electromechanically ruggedized and safe to operate near avionics and flight-critical systems; (4) have a closed-loop thermal control for temperature; (5) be able to repair skins, fairings, panels, and access doors; and (6) have a weld strength of at least 70% of the parent material.

Next Generation Tropical Cyclone Analysis, Forecasting, and Dissemination Tactical Decision Aid Software - STTR Topic DON26TZ01-NV010

Funding Amount:

Est. $240,000

Deadline to Apply:

Est. April 29th, 2026.

Objective:

Demonstrate an improved automated tropical cyclone forecasting, analysis, and dissemination tactical decision aid capability that uses a modern containerized software backend/frontend and is able to easily integrate legacy and novel component algorithms, models, databases, and Application Programming Interfaces (APIs).

Description:

Domestic operational tropical cyclone forecasting at the Joint Typhoon Warning Center (DOW), Fleet Weather Centers (DOW), and National Hurricane Center (NOAA) have relied on the Automated Tropical Cyclone Forecast System (ATCF®) software suite for end-to-end tropical cyclone analysis, forecasting, and product dissemination for over three decades. This one-stop-shop for all data, modeling, post-processing, and user interaction for tropical cyclone information has endured due to its robust assured infrastructure, reliability, speed for executing actions, and long continuity even as forecasters and information have evolved. However, as compute environments and programming languages have changed, it has become more difficult to maintain and upgrade legacy software to take advantage of new capabilities.

This STTR topic seeks the development of a prototype software suite that can learn lessons from the success of ATCF®, but is architected in a modern software ecosystem to mitigate current workflow disadvantages. Fundamentally, the goal is a modular and containerized software application that can variously interact with legacy, current, and future software suites such as components of ATCF®, the Naval Integrated Tactical Environmental System Next Generation (NITES-Next) program, the NOAA Advanced Weather Interactive Processing System (AWIPS), and other back-end and front-end APIs. The software architecture must be designed from the outset to comply with DOW DevSecOps principles and prepare the system for the Risk Management Framework (RMF) process. Desired software requirements include design in a modern broadly supported and maintained open programming language that can run online or offline on premises or in a cloud compute environment; hardening against connectivity and bandwidth issues; separation of functionality between logic, database, analysis algorithms, forecast generation , user interface, and dissemination layers; modular component development where different parts can interoperate with other software; and the ability to quickly address software updates and functionality and revert on the client side.

A dual-pronged approach to improving workflow for the tropical cyclone forecast process is envisioned, with parallel development tracks for software architecture creation and decision support aid integration. While the focus of tropical cyclone tools in the 1980s through 2000s was on track and intensity prediction, the forecasting mission has increasingly expanded. This includes the ability to track before storms have formed; 3D storm structure and rainfall evolution; ocean and wave field information; storm surge and hazards; probabilistic uncertainty; and emerging machine learning tools. The software should be capable of generating and disseminating an automated, objectively optimal analysis and forecast product from available data — that is, without significant manual human effort. It is not expected that all these efforts are achievable within the scope of this STTR effort; however, the priority development schedule must be justified, and the software solution must be able to accommodate all of these components within a future strategic plan.

Back-end capability should include: (1) a modern development software framework that can easily include or remove proprietary and open source algorithms as desired and is built and deployed as a containerized architecture; (2) a robust state management (e.g., database) for storm information and aids with backwards compatibility and export for current ATCF® “deck file” formatting; (3) concurrency for data fetching and processing to reduce data latency for time-critical forecast workflows; and (4) defined APIs to provide data access to clients, such as front-end graphical user interfaces (GUI) or downstream machine-to-machine programs. Further, the back-end capability should support backup capability, likely through a distributed system of servers.

Front-end capability should include: (1) thin client(s) for use on desktop workstations and possibly within web browsers, facilitating both on-site and remote operation with both client-side and server-side rendering tested for DOW network responsiveness; (2) flexible means of calling external scripts/functions/APIs with configurable input data, allowing forecasters to trigger different production pipelines and workflows that could be defined externally; (3) editable runtime configuration facilitating separate profiles for different operational systems or users; (4) means to integrate with internal and/or external AI systems or agents to facilitate future workflows; and (5) GUI and storm management capabilities consistent with ATCF®, with additional emphasis on performant map navigation and rendering, multi-product and format overlays (from gridded and sparse data, such as from kml, kmz, ShapeFiles, GeoTiff, HDF, netCDF, GRIB2, Zarr, GeoJSON, etc.), and dynamic filtering and alerts for data as they populate in real time. It is imperative that software developed be done so with an emphasis that support does not require skills beyond those currently required and normally used by support staff at forecast centers.

Objective:

Design, develop, and test a reentry body antenna or antenna system capable of transmitting high speed, real time, inflight, encrypted data. The data transmission should be in bands alternate to S band such as the K & Ka bands and communicate with geostationary satellites used as a pass-through mechanism to relay the encrypted data to ground.

Description:

The development of a next-generation telemetry communications antenna for Navy Submarine Launched Ballistic Missile (SLBM) reentering test bodies is critical in advancing developmental technologies being evaluated on flight tests. While common ground tests such as wind tunnels, arc jets, and vibration provide insights into predictable reentry environments, flight testing remains the gold standard in evaluating reentry bodies (RBs) and their onboard technologies. Flight tests evaluate a reentry body’s ability to withstand the harsh and sometimes unpredictable environments of flight to include launch, separation, and reentry.

The current technology to monitor SLBM payloads during flight include a transmitter/receiver system between the reentry body and ground stations. Data is captured during flight and transmitted to the ground in the S band (2-4 GHz), making data transfer slower than higher frequency bands [Ref 3]. Due to the S band being a highly populated frequency band and the power on the RB required to telemeter data in the S band back down to the ground receiver, midflight data transmission is both slow and costly. Additionally, since the transmitter/receiver system today is only between the RB and ground station, real time data transmission is lost during a portion of the flight when the RB is the furthest away from the ground, otherwise commonly known as “over the top” of the flight trajectory as well as during reentry when the body enters plasma blackout. To solve this problem, the technology proposed should use alternate frequency bands, such as K and Ka bands (18-40 GHz) and make use of geostationary satellites as a pass-through mechanism to capture real time data from the RB and telemeter the encrypted data back down to the ground at high speeds in order to minimize data transmission latency and loss. The use of alternate frequency bands allows for high data rate information exchange [Ref 1]. This new technology would solve the issue of losing real-time data transmission midflight.

By having real-time, high-speed data throughout the duration of flight on a flight test, the Navy can better understand technology performance throughout the various environments and environment transitions and can more effectively diagnose issues or failures resulting in faster technology maturation.

Objective:

Simplify the thermal management of practical atom-based quantum sensors based on alkali atoms by creating a passive atom source operated at thermal equilibrium based on a synthetic alkali vapor density for rubidium or cesium atoms.

Description:

Quantum sensors based on atoms offer the opportunity to produce measurements with excellent sensitivity or long-term stability, making them attractive use in atomic clocks, magnetometers, or inertial sensors. In these sensors, the atomic vapor represents the sensing media where variations in signal magnitude from fluctuations in atom number can lead to instability or loss of sensitivity. Maintaining consistent signal throughout environmental conditions represents one of several key design criteria for atom-based sensors for use outside the laboratory.

Many atom-based sensors rely on heavy alkali atoms, specifically rubidium and cesium. This is because of the simplified, hydrogen-like energy level structure, the availability of narrow-linewidth semiconductor diode lasers on the relevant D1 (795/895 nm) and D2 (780/852 nm) transitions, the accessibility of commercial microwave electronics at the 3-10 GHz hyperfine splittings, and the ease of production of vapor phase atoms at modest temperatures. The temperature dependence of the alkalis [Ref 1] leads to thermal stabilization at 80-130°C (ideal for vapor cells at 10e12-10e14/cc) or closer to room temperature (ideal for atom trapping at 10e8-10e10/cc). These temperatures rarely align with thermal profiles of other aspects of the system, requiring additional design at the expense of size, weight, and power (SWaP).

Active approaches to alkali regulation have been demonstrated to manipulate the vapor to a non-equilibrium state. These approaches involve forced chemical reactions, intercalated graphite, alkali impregnated materials glasses [Refs 2,3]. In each case, a feedback loop must respond to measurements of the vapor density, leading to extra sensor complexity.

An equilibrium vapor density represents the simplest atom source which can be synthetically adjusted to an elevated temperature through a mixture [Ref 4]. Here, a primary species mixed with a secondary species reduces the equilibrium vapor density of both species by the mixing ratio following Raoult’s Law [Ref 5]. Selecting a lower vapor density secondary species limits the negative impact of additional atom-atom collisions. Such an approach can be applied to laser-cooled systems in addition to vapor cells to enable equilibrium operation at elevated system temperature, providing tight thermal regulation at low power.

Solid-Fuel Rotating Detonation Ramjet (SF-RDR) for High-Speed Propulsion - SBIR Topic DON26BZ01-NV036

Objective:

Develop a throttleable solid-fuel Rotating Detonation Ramjet Engine (SFRDE) system by integrating a controllable gas generator to precisely regulate fuel supply, enabling stable and efficient Rotating Detonation Engine (RDE) operation.

Description:

The Department of Navy (DON) seeks innovative solid-fuel detonation-based propulsion solutions that can deliver superior performance and operational flexibility. The RDE is a promising candidate to replace current constant-pressure combustion systems, due to its high-thermal efficiency, wide-operating Mach range, short combustion time, and small volume. However, to fully realize the benefits of an RDE for naval applications, particularly in the context of ramjet operation, the ability to operate an RDE on solid fuels and precisely control thrust output is crucial. This SBIR topic focuses on developing a throttleable solid-fuel rotating detonation ramjet (SFRDE) system, enabling dynamic adjustments to a coupled gas generator to enable optimal performance across a wide range of mission profiles.

To date, RDEs have been demonstrated to operate at ramjet relevant conditions; however, the applicability of RDEs to ramjet cycles has largely focused on the use of gaseous or liquid fuels [Refs 1, 2]. The use of solid fuels in RDEs presents additional complexities. Fuel formulations must be carefully tailored to provide detonable fuel at ramjet relevant temperatures. The use of a gas generator to provide the combustible mixture could potentially lead to solid particles clogging the fuel injectors. The design of the gas generator is also crucial to provide a mixture adequate for sustained detonability and coupling with the RDE inlet. Recent studies have demonstrated the viability integration of solid propellants and rotating detonation engines through the use of gas generators [Ref 3]. The proposed research should address the following two key areas to achieve a throttleable SFRDE:

Throttleable Gas Generator Development: Design and develop a compact, lightweight, and throttleable gas generator capable of precisely controlling the flow rate and composition of the fuel and/or oxidizer supplied to the RDE. Additional considerations should include the selection of appropriate gas generator propellants based on performance, stability, and safety considerations, as well as consideration of ignition methods suitable for the gas generator.

Combustion Chamber Design: Optimize the rotating detonation engine combustion chamber design for stable rotating detonation wave propagation and efficient mixing of the gas generator's output with the primary oxidizer stream. Design considerations should include injector geometry and placement to promote rapid mixing and flame stabilization; chamber geometry to facilitate detonation wave initiation and propagation; and thermal management strategies for both the gas generator and combustion chamber.
