About this opportunity
The Defense Logistics Agency (DLA) Aviation is seeking small business suppliers to provide C-5 Galaxy aircraft seals across 31 identified National Stock Numbers and part numbers. These seals are critical components that maintain aircraft pressurization and aerodynamic performance during flight operations. Offerors must demonstrate manufacturing capability and obtain qualification from C-5 engineers at Warner-Robbins Air Logistics Complex by meeting the source qualification statement (SQS) requirements before seals can be listed on the applicable source qualification list (SQL) and contract award. All supplied seals must be authorized by the qualifying activity and listed on the SQL prior to contract award, with seals required to support a 90-day production flow schedule to meet global DoD customer needs. The Request for Proposal is anticipated for release in January 2026, with responses to this pre-solicitation notice due by December 10, 2025, and contract award expected in March 2026. This is a sources sought announcement for informational purposes only and does not constitute a solicitation or commitment by the government.
This procurement is designated as a Total Small Business set-aside, restricting competition to qualifying small business entities. No incumbent contractors or current suppliers are identified in the pre-solicitation notice. The contract will be awarded for a period of 1-2 years to support the 90-day production flow schedule, though no specific award values or quantity requirements are disclosed in this pre-solicitation phase. The exploration effort may result in multiple contract awards to qualified suppliers, indicating the government's intent to develop a diversified supply base for C-5 seals. Interested small businesses should prepare their technical and business information now to meet the anticipated January 2026 RFP release, as the qualification process through the SQS will be a critical path item for contract award consideration in March 2026.

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
