The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of 10 units of control servo automation systems. This requirement is a sole source procurement, necessitating Government Source Approval prior to award, as the Government does not possess sufficient data to contract with other sources. The items are critical for military operations and are intended for Foreign Military Sales to Greece, Norway, Spain, and India, with specific quantities allocated to each country. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and direct any inquiries to Julianna Macrillo at julianna.r.macrillo.civ@us.navy.mil or by phone at 215-697-1227.
