DLA Troop Support in Philadelphia, PA is conducting market research via a sources-sought/RFI for a Life Preserver Vest (Aircrew Emergency Egress), NSN 4220-01-708-3638, currently approved from TIAX LLC (P/N 100300-A). The estimated annual requirement is about 120 units under a one-year base period with potential multi-year options, delivered FOB destination to designated DoD supply depots/CONUS stock locations. The vest is critical life-support equipment for Navy and Air Force aircrew and must permit cockpit mobility while being compatible with standard parachutes and harnesses. The Government lacks a complete TDP and manufacturing rights, so it will consider exact part-number sources, authorized distributors, and alternate/reverse-engineered/equivalent products that can provide engineering, test, qualification, and compatibility data for ESA approval. Interested qualified firms should provide a capability statement covering company profile, source status, technical/manufacturing capability and capacity, quality certifications, lead time, commerciality, and ROM unit pricing/warranty terms.
