Funding Amount:

Est. $2,000,000

Deadline to Apply:

July 22nd, 2026

Objective:

The Air Force seeks to enhance the operational reliability and readiness of the MHU-196 Weapons Hydraulic Trailer in cold-weather environments by addressing performance degradation of hydraulic systems under extreme conditions. Current mitigation measures have proven insufficient, resulting in delayed weapons loading, increased equipment downtime, increased manpower hours, and added maintenance burden. These limitations directly impact sortie generation timelines, particularly for missions requiring rapid response and sustained readiness in arctic and contested environments.The objective of this D2P2 effort is to prototype, test, and validate a heating capability that ensures hydraulic systems maintain consistent performance in low-temperature environments. By focusing on accelerated development at this phase, the Air Force intends to leverage demonstrated feasibility and commercial technologies to rapidly transition into integrated testing and qualification. The desired outcome is an adaptable, mission-ready capability that improves sortie generation, extends equipment service life, and reduces operator risk without increasing logistical burden.This D2P2 effort emphasizes speed-to-field and risk reduction by building on work already accomplished in earlier analyses and market investigations. The immediate goal is to deliver a solution capable of maintaining operational continuity for weapons handling and loading operations in austere or extreme climates. Success in this phase will enable flexibility for future adaptation, scaling, and integration across additional weapons handling platforms and mission sets.

Description:

The MHU-196 Weapons Hydraulic Trailer is a critical Air Force system used to transport, load, and service munitions across bomber and nuclear platforms. Its performance directly supports sortie generation timelines and mission readiness. In cold-weather environments, however, the trailer’s hydraulic systems suffer from degraded performance due to thickened hydraulic fluid, stressed seals, and overburdened pumps. This results in delayed weapons loading, increased downtime, and higher maintenance costs.Interim solutions, such as reservoir heaters and external “boogie skirt” heating, have been fielded but are not effective in sustaining hydraulic performance across the full system. This operational gap creates a risk to munitions handling and sortie generation for AFGSC, and other commands operating in austere or arctic conditions.This challenge presents a clear opportunity to develop an improved thermal management capability for the MHU-196 that ensures reliable operation in extreme environments. The desired outcome is a validated, mission-ready system that maintains hydraulic performance in cold weather, reduces maintenance burden, and extends trailer service life. Such a solution will directly improve sortie generation rates, increase operational resilience, and reduce risks to operators and equipment. Leveraging commercial innovations in heating and insulation technologies, this effort can provide a rapid, low-risk pathway to fielding an effective solution.The project begins at an estimated TRL 4–5, with feasibility already established through earlier analysis, market research, and evaluation of interim heating methods. The goal at the end of Phase II is to achieve TRL 7–8 by developing, integrating, and demonstrating a prototype in relevant operational environments, with a clear roadmap for certification and production. Required efforts will include design and fabrication of a prototype heating system, laboratory and field testing in cold-weather conditions, assessment of compliance with nuclear and Air Force standards, and evaluation of logistics, maintainability, and lifecycle cost.The minimum acceptable deliverables for Phase II are a fully integrated prototype demonstrated on an MHU-196 trailer, a test and evaluation report documenting laboratory and field performance, a certification roadmap aligned with nuclear and Air Force requirements, and a transition plan detailing options for scaling and fleet-wide implementation. Advancing this capability through a Direct to Phase II effort ensures accelerated development and transition, closing a validated operational gap and enhancing readiness for critical munitions operations in contested and extreme environments.

PHASE I

As this is a Direct-to-Phase-II (D2P2) topic, no Phase I awards will be made as a result of this topic. To qualify for this D2P2 topic, feasibility is demonstrated through a prior "Phase I-type" effort that does not constitute work undertaken as part of a prior or ongoing SBIR/STTR funding agreement. Documentation establishes a clear understanding of the operational problem, validates solution feasibility, and provides evidence that the proposed approach is mature enough to proceed directly into prototyping under Phase II.The operational problem has been validated. The MHU-196 Weapons Hydraulic Trailer experiences significant degradation in cold-weather environments, delaying sortie generation and increasing maintenance burden. Hydraulic fluid thickens, seals and pumps are stressed, and downtime increases in sub-zero conditions. Interim measures, including Zerostart reservoir heaters and external “boogie skirt” heating, have been employed but do not maintain hydraulic fluid temperature across the full system. This persistent gap is documented through field reports and supporting analysis.Phase I-type feasibility work has already been completed. Technical reviews and market research identified heat trace with integrated insulation as the most promising approach to sustain system performance across the trailer. Commercial vendor data, engineering evaluations, and comparative analysis of performance characteristics—including thermal efficiency, durability, and scalability—demonstrate that mature technologies exist and can be adapted to meet Air Force requirements, while providing sustainment and lifecycle cost benefits for reduced maintenance and manpower. Feasibility documentation includes operational problem statements, third-party and government analysis, vendor specifications, and measurements from comparable use cases. This body of work confirms an initial entry point of TRL 4–5, with a clear path to advance to TRL 7–8 by the end of Phase II through prototype development, integration, and demonstration in relevant operational environments.The prior analysis and validation efforts fulfill the objectives of a Phase I effort by defining the problem, demonstrating technical feasibility, and identifying viable solution pathways. With technical risk reduced, this D2P2 effort can focus directly on prototyping, environmental testing, certification, and preparation for transition to operational use.

PHASE II

Phase II will design, integrate, and demonstrate a heating capability for the MHU-196 Weapons Hydraulic Trailer to ensure reliable operation in cold-weather environments. The desired outcome is a prototype that sustains hydraulic performance in sub-zero conditions, improving sortie generation, reducing downtime, and lowering maintenance risks. The effort will advance the system from TRL 4–5 to TRL 7–8 by the end of Phase II.The Period of Performance includes prototype design, fabrication, and integration into the MHU-196 trailer. Functional requirements include maintaining hydraulic fluid viscosity within operating parameters, enabling cold-weather startup within defined timelines, and sustaining performance across the full hydraulic circuit. The system must be energy-efficient, durable, and compatible with existing trailers without adding logistical burden.Testing will consist of laboratory validation, environmental chamber evaluation, and field demonstrations in cold-weather environments. Success will be measured by the ability to maintain hydraulic fluid temperatures in the target range (down to -25°F), reduce cold-start times versus current procedures, and confirm that no adverse impacts occur on trailer reliability or maintainability. Compliance with Air Force safety standards and a defined nuclear certification pathway will also be required.Use cases include munitions loading in arctic climates, dispersed operations under Agile Combat Employment, and nuclear sortie generation for AFGSC. Success will be defined by seamless integration into the existing fleet, improved operational resilience, and reduced sustainment burden.Minimum deliverables are: a prototype heating system integrated and demonstrated on an MHU-196; a test and evaluation report covering lab, field, and compliance results; a certification and transition roadmap; and a plan for scaling across the fleet.By the end of Phase II, the Air Force will have a validated capability to close the cold-weather performance gap for the MHU-196, strengthening readiness and ensuring reliable munitions handling in extreme environments.

PHASE III DUAL USE APPLICATIONS

Phase III will transition the MHU-196 Weapons Hydraulic Trailer heating capability into full operational use, with an expected entry point of TRL 7–8 at the conclusion of Phase II. Efforts will focus on final qualification, nuclear certification, and scaling integration across the MHU-196 fleet to ensure reliable cold- weather performance for munitions handling operations. Military applications include supporting AFGSC bomber and nuclear sortie generation, where hydraulic trailer reliability directly impacts alert posture and mission timelines. The system also applies to PACAF and USAFE operations in arctic climates, supporting Agile Combat Employment and dispersed operations, and to AETC training environments, ensuring Airmen gain proficiency on equipment consistent with operational systems. Commercial applications extend to industries reliant on hydraulic systems in cold environments, including airport/aerospace ground support equipment, construction, mining, oil and gas, logistics, and emergency/disaster response trailers. These sectors face similar cold-weather challenges, and a heating solution that reduces downtime and maintenance can deliver measurable cost savings and improved efficiency. Transition planning will include production scaling, integration with Air Force sustainment organizations, and alignment with nuclear certification and Air Force safety requirements. Engagement with AFMC, AFSC, and Air Logistics Complexes will ensure smooth sustainment pathways, while further opportunities exist to adapt the technology to other weapons trailers and expeditionary support equipment.
