The Defense Logistics Agency (DLA) Weapons Support (Richmond) is seeking potential small business suppliers for C-5 aircraft seals (see attached NSN list) for supporting global DoD customer needs. This exploration may lead to multiple contracts. The Request for Proposal for this small business set-aside is anticipated to be released in January of 2026 with award in March 2026. Contracts will be for a period of 1-2 years.

The C-5 Galaxy, a large military transport aircraft crucial for the US Air Force's heavy airlift capability, relies on seals for preventing air and pressure flow out of the aircraft allowing it to maintain pressure at altitude and giving the desired aerodynamic qualities to the wing and moving components. This initiative aims to ensure a high supply of quality C-5 seals to support the 90-day production flow schedule.

Seals furnished under this effort must be products that are authorized by the qualifying activity for listing on the applicable source qualification list (SQL) before contract award. The C-5 engineers at Warner-Robbins Air Logistics Complex (WR-ALC) developed a source qualification statement (SQS) for this purpose to qualify offerors for the SQL. Offerors must demonstrate their capability to manufacture seals to the engineering source activity (ESA) as described in the SQS. Those offerors deemed technically qualified will be added to the source approval worksheet
