The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of the EFIS Junction Box, A. This is a sole source requirement, indicating that the government lacks sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The items are critical components in aircraft systems, and interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure to be considered. For inquiries, potential bidders can contact Samantha Freedman at 215-697-6566 or via email at samantha.m.freedman.civ@us.navy.mil.
