Program detail
Mission & acquisition strategy
The Aircrew Systems Development program (PU 0606) provides Engineering and Manufacturing Development (EMD) of Aviation Life Support Systems to protect aircrew and flight deck personnel from current and future threats including: directed energy weapons, chemical/biological/radiological agents/fallout, ballistic projectiles, temperature extremes, heat/fire, low concentration oxygen environments, high dynamic forces during emergency egress, hearing loss, high "G" forces, and survivability during isolated personnel events.
Leverage Commercial-Off-The-Shelf/Non-Developmental Items where possible. Full and open competition utilizing negotiated best value procedures applied when appropriate. Cost plus fixed fee contracts are employed when sufficient technical complexity and uncertainty is associated with design and development.

Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix.

Project detail
What project 0606 buys
AIRCREW SYSTEMS: Aircrew Systems include Cold Weather/Anti-Exposure Systems (CWAES), Helmet, Mask, Regulator (HMR), Survival Vest Systems Improvement (SVSI), and Improved Joint Helmet Mounted Cueing System (IJHMCS). The CWAES program will design, test, and qualify improved cold weather/anti-exposure systems. System components will provide reduced thermal burden, increased mobility, and superior water intrusion resistance while maintaining protection levels. The improved system will reduce fatigue and dehydration, enable operating at optimum performance during extended missions, provide protection from exposure, and provide improved survivability during extended recoveries. The SVSI program provides for an improved RW/TR aircrew survival vest to address safety and performance issues with the currently fielded solution. Vest systems include, at a minimum, aircrew life support equipment and armor carrier, hoisting capability, mobile aircrew restraint, and life preserver. IJHMCS will mitigate aircrew back and neck strain/fatigue and replace the JHMCS Helmet Mounted Day Display and Night Vision Cueing Device (NVCD) with a single day/night, digital color-capable helmet-mounted display. IJHMCS will integrate onto the helmet solution identified in the Helmet Mask Regulator (HMR) program. AIRCREW SAFETY IMPROVEMENT PROGRAM: Aircrew Safety Improvement Program (ASIP) provides continuing development and qualification in response to high priority, emergent aircrew systems deficiencies, capability gaps, obsolescence, and readiness issues. ASIP addresses critical safety and performance issues while enhancing safety and survivability with solution improvements across the aircrew systems portfolio. Efforts are prioritized according to fleet demand signals.

Project detail
What project 9099 buys
Physiological Episodes includes Helmet Mask Regulator (HMR). HMR: Improved helmets, masks, and regulators are required to mitigate physiological episodes. This program determines what improvements are needed and develops the material solution. The closeout of RCCA action items is paramount to the Naval Aviation Enterprise's efforts in mitigating physiological episodes, restoring confidence in the aircraft, and most importantly, keeping our USN and USMC aircrew safe.
