The Department of Defense, through the Defense Logistics Agency, is seeking proposals for the procurement of fuel cells for the KC-135 aircraft, under solicitation number SPRTA1-25-R-0042. The contract will be a firm fixed price type with a maximum quantity of 135 units over a three-year period, requiring deliveries of 30 units each year, with the final delivery due by October 1, 2025. These fuel cells are critical for inflight refueling operations, and the government intends to negotiate with a limited number of sources due to the specialized nature of the requirements. Interested parties should submit their proposals by January 10, 2025, and can contact David Garcia at 405-739-5501 or via email at david.garcia.59@us.af.mil for further information.
