Cylinder

The Defense Logistics Agency Aviation is procuring two cylinder assemblies (NSN 1650-01-417-8523) used in F-16 aircraft hydraulic systems under solicitation SPRHA4-26-Q-0365. This acquisition is restricted to qualified sources only, with current qualified sources identified as Lockheed Martin (CAGE 81755) and Arkwin Industries (CAGE 98391); contractors desiring to become qualified sources must submit a qualification package meeting the Manufacturing Qualification Requirements, which includes demonstrating manufacturing and inspection capabilities, providing a complete data package, submitting a qualification test plan for government approval, and delivering a pre-contract award qualification article for evaluation. The government will evaluate proposals using range pricing for quantities of 1-2 units, 3-4 units, 5-10 units, 11-15 units, and 16 or more units, with evaluation based on the applicable quantity price range at the time of award. The initial solicitation was posted February 6, 2026, with an original quotation deadline of March 9, 2026; however, a March 18, 2026 amendment added range pricing requirements and did not extend the offer receipt deadline. All offerors must acknowledge receipt of the amendment prior to the original offer submission deadline or risk rejection of their proposals.

This procurement includes no set-aside designation and is restricted to U.S. contractors only, with Buy American compliance required. The two incumbent qualified sources are Lockheed Martin and Arkwin Industries, and no budget range or estimated award value is disclosed in the solicitation documents. The government seeks firm fixed price delivery of two units by December 31, 2027, with delivery FOB origin to an overseas Foreign Military Sales location (DJO002) supporting FMS case JO-D-SAC/053. Items must comply with AS9100 quality standards, military packaging per MIL-STD-2073-1E, and military marking per MIL-STD-129R, with inspection and acceptance occurring at the origin location. The estimated qualification cost for new sources is $1,250,000 with an estimated completion timeline of 365 days, representing a significant barrier to entry for potential new competitors.
