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 SPRTA1-25-R-0046. The contract will be a firm fixed price type with a maximum quantity of 192 units over a three-year period, requiring deliveries of 43 units in the first and second years, and 42 units in the third year, with a final delivery date on or before 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.
