The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of radio frequency amplifiers as spare parts. 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. These amplifiers are critical components for various defense applications, necessitating government source approval prior to award, which requires interested parties to submit detailed information as outlined in the NAVSUP WSS Source Approval Brochure. Proposals must remain valid for a minimum of 120 days following submission, and inquiries can be directed to Cody Cameron at Cody.P.Cameron@navy.mil or by telephone at 215-697-1202.
