The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of modem communication spare parts. This requirement is classified as a sole source procurement, meaning 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 items are critical for maintaining operational capabilities, and interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. Proposals must remain valid for a minimum of 120 days, and inquiries can be directed to Cody Cameron at cody.p.cameron@navy.mil or by phone at 215-697-1202.
