This is a procurement for 67 hydraulic coolers (NSN 1650-01-276-5897) for the B-1 aircraft, with delivery required to Tinker AFB, OK, on or before July 3, 2026. The government does not own the technical data needed for manufacture, so interested firms must contact the OEM, Ametek Thermal Systems, Inc. This is not a set-aside, and the notice states it is not a request for competition, as the government intends to negotiate with a limited number of sources. However, all proposals received within 45 days of the synopsis publication will be considered.
