DIU - Massed Modular Aircraft CSO
Below is a brief summary. Please check the full solicitation before applying (link in resources section).
Executive Summary:
The Defense Innovation Unit (DIU) is seeking commercial solutions for Massed Modular Aircraft (MMA)—cost-effective, theater-range unmanned aircraft designed to operate in large numbers despite expected combat losses. The Joint Force is looking for modular platforms capable of carrying a variety of payloads, including Full Motion Video (FMV) sensors, while supporting long-range strike, intelligence, electronic warfare, and communications missions.
DIU is specifically interested in technologies that can provide affordable, rapidly manufacturable unmanned aircraft capable of overwhelming sophisticated air defenses through mass rather than relying on small numbers of high-cost platforms.
Applications are due by 2026-07-23 23:59:59 US/Eastern Time. Companies should begin preparing immediately, as DIU rarely grants extensions and solution briefs must be submitted electronically through the DIU website.
How much funding would I receive?
The solicitation does not specify the amount of the award but typically these opportunities range from about $500,000 to about $5 million
What could I use the funding for?
Funding may support prototype projects for technologies that address the Massed Modular Aircraft Area of Interest, including solutions that provide:
Cost-effective, theater-range modular unmanned aircraft
Long-range payload delivery
Full Motion Video (FMV) sensor integration
Weapons employment
Intelligence collection
Electronic warfare
Communications relay
Modular payload integration
Rapid technology integration using Modular Open Systems Approach (MOSA) principles
Prototype development and flight testing
The solicitation identifies the following desired capabilities:
Payload capacity of at least 2,800 lbs
Unrefueled combat radius of at least 2,300 nautical miles
One-way self-deployment of at least 8,000 nautical miles
One-to-many operator-to-UAS control
Hybrid SATCOM/mesh networking
Operation from 6,000-foot or shorter prepared or semi-improved runways
Approximately 25kW available power and 5kW cooling for payloads
Full-scale prototype flight testing within 21 months of award
Target Initial Operating Capability (IOC) in FY2031 consisting of 20 mission-ready aircraft delivered to an operational unit.
Capabilities Sought:
Primary Attributes Sought
Risk Tolerance: Designed for affordable, high-rate manufacture, and minimized total ownership cost
Sufficient Munition and Sensor Payload Capacity: Payload capacity of at least 2800 lbs
Meaningful Range: Unrefueled combat radius of at least 2300 nautical miles while carrying payload and ability to self-deploy one-way at least 8,000 nautical miles
Maximum Interoperability, and Integration: Capable of rapid integration and upgrades via exploitation of the following Modular Open Systems Approach (MOSA) tenets: a) Government Reference Architectures; b) Model Based Systems Engineering; c) formal methods-based software verification
Secondary Attributes Sought
Autonomy for Control: a one-to-many operator-to-UAS control ratio
Sufficiently Resilient and Integrated Communications: Hybrid SATCOM/mesh network connecting to Department of the Air Force-Battle Network (DAF-BN); execution of local airfield operations (taxi, takeoff, landing, and divert) under highly degraded or denied primary C2/SATCOM conditions
Tactically Relevant: At least 200 knots true airspeed; operation from 6,000-foot runway or shorter, semi-improved or prepared
Sufficient SWaP-C: Sufficient available size, weight, power (25kW), and cooling (5kW) to host a variety of internal and/or external payloads. Enables rapid payload exchange
Are there any additional benefits I would receive?
The solicitation states that a successful Prototype Other Transaction Agreement may result in the direct award of a follow-on production contract or agreement without further competitive procedures if the prototype project is successfully completed.
The follow-on production effort may be used by one or more Department of Defense organizations and could be significantly larger than the Prototype OT agreement.
What is the timeline to apply and when would I receive funding?
Application deadline
2026-07-23 23:59:59 US/Eastern Time
After submission:
DIU evaluates Phase 1 Solution Briefs.
Selected companies are invited to a Phase 2 virtual or in-person pitch.
Companies selected after the pitch may be invited to submit a full written proposal for a Prototype OTA.
Full-scale prototype flight testing is expected within 21 months of award.
The target Initial Operating Capability (IOC) is FY2031.
The solicitation does not specify when awards or funding will be issued.
DIU states it will generally notify companies within approximately 30 days if it is interested in moving forward with a pitch.
Where does this funding come from?
Funding comes from the Defense Innovation Unit (DIU) using the Commercial Solutions Opening (CSO) process.
Awards are made as Prototype Other Transaction Agreements (OTAs) under 10 U.S.C. § 4022.
Who is eligible to apply?
The solicitation states it is open to:
U.S. vendors
International vendors
To utilize an Other Transaction Agreement, the requirements of 10 U.S.C. 4022 must be satisfied, including at least one of the following:
At least one nontraditional defense contractor or nonprofit research institution participates to a significant extent;
All significant non-government participants are small businesses or nontraditional defense contractors; or
At least one-third of the prototype project cost is funded from non-federal sources.
Companies selected for award that do not already have a CAGE code are required to register in SAM.gov.
Who is not eligible to apply?
The solicitation does not identify specific categories of organizations that are prohibited from applying.
However, companies must satisfy the statutory eligibility requirements for Prototype Other Transaction Agreements under 10 U.S.C. 4022, and companies receiving awards must register in SAM and meet federal responsibility requirements.
What companies and projects are likely to win?
Based on the stated evaluation criteria, DIU is seeking solutions that:
Directly address the Massed Modular Aircraft problem statement
Demonstrate strong technical merit
Are technically feasible
Offer a unique or innovative commercial approach
Show company viability
Demonstrate manufacturability
Present acceptable pricing and schedules during Phase 2
Address modularity, affordability, long-range performance, and operational relevance
The solicitation also emphasizes demonstrated commercial technology rather than conceptual ideas whenever possible.
How competitive will this solicitation be?
The solicitation indicates that DIU routinely receives more Solution Briefs than it has resources to award.
Only a select number of companies will be invited to the Phase 2 pitch, even if multiple submissions are considered technically meritorious.
Are there any restrictions I should know about?
Applicants should note:
Solution Briefs should be approximately 5 pages or 15 slides.
Submissions must be submitted electronically through the DIU website.
Late submissions will not be evaluated.
Only one concept may be included in each Solution Brief.
Solution Briefs must be unclassified.
Companies must certify submission requirements, including compliance regarding Controlled Unclassified Information.
Any resulting agreement will require compliance with Section 889 of the John S. McCain National Defense Authorization Act for Fiscal Year 2019.
Prototype projects generally should have periods of performance no greater than 24 months.
How long will it take me to prepare an application?
The solicitation does not specify the expected preparation time.
Applicants are encouraged to prepare a concise Solution Brief that is approximately five pages or fifteen slides and includes company information, an executive summary, technology description, commercialization information, and company viability details.
