This activity requests $213.9M in FY2027, 100% of project 3148, up 4179% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 3148 of PE 0207147M. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

FY2027 planned work

In FY 2027, flight test prototype air vehicle for demonstration and evaluation of Full System Control Segment and Air Vehicle integration capability and critical systems attributes (Command and Control (C2), air vehicle performance and mission system effectiveness). Demonstration and evaluation efforts of mission system effectiveness will use relevant threats within intended Area of Operations (AO). Efforts will include maximizing alignment with USAF and DoN CCA efforts to reduce duplication and enhance interoperability through the use of compatible C2 implementations, mission systems, and common control architecture. Prototyping and experimentation efforts will include prototyping of expeditionary air vehicle components and subsystems focused on electronic warfare subsystem and payload enhancements, interoperability via communications and datalinks, mission systems computing, C2 (air/ground-based) integration architecture interoperability, and open architecture applications. This will include Systems Engineering Technical Review (SETR) events driving toward an MVP configuration. Demonstration of prototyping activities, including mission system integration and MVP flight test teamed with crewed aircraft, will maximize collaborative evaluation environments, which enable developmental and operational evaluation of prototypes and tactics development (Air Test and Evaluation Squadron Two Four (UX-24) and Marine Operational Test and Evaluation Squadron One (VMX-1)) during Fleet exercises and Weapons and Tactics Instructor (WTI) Courses hosted by Marine Aviation Weapons and Tactics Squadron One (MAWTS-1).

FY2026 to FY2027 change

Funds increase from FY 2026 to FY 2027 to support continued development and test of Air Vehicle, Mission Systems, and Control Segment Other Transaction Authority (OTA) agreements, as well as associated Integrated Laboratory and acquisition management support.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

In FY 2026, deliver a prototype air vehicle with fully integrated mission systems for demonstration and evaluation of Conventional Takeoff and Landing (CTOL) capability and critical systems attributes (Command and Control (C2), air vehicle performance and mission system effectiveness). Demonstration and evaluation efforts of mission system effectiveness will use relevant threats within intended Area of Operations (AO). Efforts will include maximizing alignment with USAF and DoN CCA efforts to reduce duplication and enhance interoperability through the use of compatible C2 implementations, mission systems, and common control architecture. Prototyping and experimentation efforts will include prototyping of expeditionary air vehicle components and subsystems focused on launch and recovery, CTOL capability, electronic warfare subsystem and payload enhancements, interoperability via communications and datalinks, mission systems computing, C2 (air/ground-based) integration architecture interoperability, and open architecture applications. This will include SETR events driving toward an MVP configuration. Demonstration of prototyping activities, including mission system integration and MVP flight test teamed with crewed aircraft, will maximize collaborative evaluation environments, which enable developmental and operational evaluation of prototypes and tactics development (Air Test and Evaluation Squadron Two Four (UX-24) and Marine Operational Test and Evaluation Squadron One (VMX-1)) during Fleet exercises and Weapons and Tactics Instructor (WTI) Courses hosted by Marine Aviation Weapons and Tactics Squadron One (MAWTS-1).

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 100% of project 3148's FY2027 request and 100% of PE 0207147M's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
