About this opportunity
The Department of the Air Force Materiel Command Lifecycle Management Center at Robins Air Force Base is seeking to establish a five-year Requirements contract for the repair of M61A1 20mm Hydraulic Drive (HyDrive) units, which are critical components for sustaining the 20mm M61A1 Gatling gun weapon system on F-16 fighter aircraft. The contract will encompass inspection, evaluation, repair, and testing services for the HyDrive, which consists of a control valve and motor that provides mechanical power for operating the Gatling gun. The procurement will be conducted under limited competition authority (FAR 6.302-1) due to market research findings that only a limited number of responsible sources possess the requisite technical capabilities and the government's lack of a complete technical data package necessary for full and open competition. The formal Request for Proposal is anticipated to be issued on or around March 2, 2026, with proposals due approximately 45 days thereafter, and interested parties should contact the Procuring Contracting Officer/Buyer for additional information. The pre-solicitation notice was posted on February 6, 2026, with a due date of March 1, 2026.
This procurement carries no set-aside designations for small businesses or other special categories. The contract will consist of a 12-month base ordering period followed by four additional 12-month ordering periods, for a total contract duration of five years. The best estimated quantity is 20 units per ordering period across all five periods, with the HyDrive identified by National Stock Number 1005-01-061-8335 and Part Number 217F429. No specific award value or budget range was disclosed in the pre-solicitation notice, and no incumbent contractors or current contractor names were identified. Prospective offerors are advised that the formal solicitation will be issued directly to sources identified during market research, making early engagement with the contracting office advisable for interested parties.
