This is a sole-source intent to award a Cost Plus Fixed Fee order to Lockheed Martin Rotary and Mission Systems for technical and process support to test MH-60R/S software. The work involves providing expertise to test teams at Patuxent River, Maryland, specifically supporting HX-21 and VX-1 in the evaluation of software and hardware, including upgrades and obsolescent parts. The period of performance is projected to be from March 2027 through March 2032. The Government cites Lockheed Martin as the only responsible source with the requisite knowledge and data to fulfill this requirement. While considered non-competitive, the Government will review any proposals received within thirty days of the synopsis publication.
