The Naval Air Systems Command intends to award a sole-source, Cost Plus Fixed Fee order to Lockheed Martin Rotary and Mission Systems in Owego, New York. The contract is for maintenance and logistics support, including 365-day inspections, for Hellenic Navy S-70B/MH-60R aircraft. The period of performance is projected to be from July 2026 through June 2027. The justification for sole-source procurement is that Lockheed Martin is the only source with the requisite technical knowledge, data, and facilities for these specific aircraft. The Government will consider proposals received within thirty days of the synopsis publication solely to determine if a competitive procurement is warranted.
