The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of antennas, as outlined in the solicitation titled "59--ANTENNA." This procurement requires compliance with specific quality requirements and the submission of detailed data for source approval, as the government does not possess sufficient data to contract with sources other than the current approved ones. The antennas are critical for various defense applications, and the evaluation of proposals will be based on the lowest price technically acceptable (LPTA) criteria. Interested vendors must contact Anna Kiessling at anna.m.kiessling.civ@us.navy.mil or by telephone at 215-697-3752 for further information and must adhere to the submission guidelines detailed in the NAVSUP WSS Source Approval Brochure.
