The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of antennas as part of a spares purchase. This requirement is classified as a sole source procurement, indicating that the government does not possess sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The antennas are critical components for military communications and operations, underscoring their importance in maintaining national defense capabilities. 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 Kate Schalck at 215-697-1020 or via email at kate.n.schalck.civ@us.navy.mil.
