The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of two Receiver, Countermeasure units. The requirement includes the submission of a proposal via email, with a focus on ensuring that all necessary documentation for government source approval is included, as these items require such approval prior to award. These receivers are critical for electronic countermeasures, which play a vital role in enhancing the operational capabilities of naval forces. Interested vendors must submit their proposals to Sarah Crompton at sarah.e.crompton.civ@us.navy.mil by the specified due date, and further details regarding source approval can be found in the NAVSUP WSS Source Approval Brochure available online.
