The Defense Logistics Agency Aviation at Tinker Air Force Base is soliciting proposals for the procurement of 30 units of the exhaust pipe (part number 65C18637-501, NSN: 1560-01-143-8559) specifically designed for the KC-135 aircraft. This procurement arises from a lack of commercial alternatives and requires adherence to AS 9100 quality assurance standards, with inspection and acceptance at the origin. The items are critical for directing exhaust gases from the F-108 engine, ensuring optimal thrust performance. Proposals must be submitted by 4:00 PM CST on June 13, 2025, with deliveries commencing on May 15, 2025, at a rate of four units per month, and interested parties can direct inquiries to Chrissy Turnage at christine.turnage@us.af.mil.
