The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two Auxiliary Power Units (NSN 7H-6105-010561314) under a presolicitation notice. This procurement is a total small business set-aside and is intended to fulfill a Foreign Military Sales (FMS) requirement, with the destination to be provided upon request. The Government has determined that it is uneconomical to purchase the data or rights necessary for contracting repair from additional sources, and thus intends to negotiate with only one source under FAR 6.302-1. Interested parties must submit their proposals or capability statements within 45 days of the notice, and can contact Alexander Davies at (717) 605-4255 or via email at ALEXANDER.DAVIES@NAVY.MIL for further information.
