The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of a control box, electric, identified by NSN 7R-1660-013344365-VH and reference number 70550-02024, with a quantity of one unit required. This acquisition is critical as the government lacks sufficient data to contract with sources other than the current supplier, emphasizing the importance of Government Source Approval prior to award. The control box is essential for aircraft air conditioning, heating, and pressurizing equipment, which plays a vital role in maintaining operational readiness and safety. Interested vendors must submit their proposals along with the necessary documentation outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
