ELECTRON TUBE, NSN 5960-01-584-9452 Part Number 587R258G02

The contract solicitation concerns the procurement of three spare Electron Tubes, identified by NSN 5960015849452 and part number 587R258G02, for use in E-3 aircraft systems. The item is a large, heavy component measuring 65 inches in length and height by 32 inches in width, weighing 460 pounds, and contains ESD-sensitive components that emit radio frequencies. The required delivery is for all three units to be shipped by June 30, 2026, to DFR002 under the Foreign Military Sales program. The acquisition is non-competitive, justified under FAR 6.302 due to the item being available only from a single approved source, CIRCOR Aerospace Inc, with no established purchase history or alternative specifications feasible for competition. The government intends to award the contract based on price and past performance, with no set-aside for small businesses, though foreign firms must consult the contracting officer prior to submission due to potential restrictions. The Electron Tube is subject to UID marking requirements and must be new and unused only. All solicitations and responses must be submitted electronically via SAM.gov; hard copies will not be accepted. The offeror must be aware that contract obligations are contingent upon the availability of appropriated funds, and no liability arises until written confirmation of funding is provided. The solicitation window closes on May 21, 2026, with a possible award date 90 days after issuance. Interested parties may contact Clifford Dockter with questions, and an Ombudsman is available to receive confidential concerns during proposal development.
