# MUX TACAIR Increment I

**R-2A activity** of project 3148 — MUX TACAIR Increment I  
**Program element:** 0207147M — (U) Collaborative Combat Aircraft  
**Component:** U.S. Navy · **Budget Activity:** 4  
**Vintage:** President's Budget PB2027

## Summary

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

**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 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).
