The government is conducting market research to identify industry sources for advanced, lightweight parachute canopy materials to support the Advanced Tactical Parachute System Design Optimization effort. The primary objective is finding a direct replacement for the legacy PIA-C-44378 Type IV fabric that reduces weight and packed volume while maintaining compatibility with the T-11R reserve canopy assembly. Interested vendors must provide comparative performance data, details on manufacturing and domestic availability, and pricing estimates for trial and full-rate production quantities. This is an RFI for planning purposes only and does not constitute a commitment to issue a future solicitation. Interested parties should submit capability responses via email to the specified government contacts.
