The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for a sole source contract to supply a Miscellaneous Relay Panel (Part Number: 71550-22905-041) for Foreign Military Sales to South Korea. The procurement requires Government Source Approval prior to award, as the Government does not possess sufficient data to contract with sources other than the current approved supplier. This relay panel is critical for aircraft operations, and interested vendors must submit the necessary documentation outlined in the NAVSUP WSS Source Approval Brochure to be considered. For inquiries, potential bidders can contact Julianna Macrillo at julianna.r.macrillo.civ@us.navy.mil or by phone at 215-697-9499.
