The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 165 units of a flight-critical computer component, identified by NSN 7R-7021-014817734-LU. The procurement requires that only sources previously approved by the Government may submit proposals, as the technical data necessary for alternative sourcing is not available, making reverse engineering uneconomical. Interested vendors must provide comprehensive documentation to demonstrate their capability to produce the item, including any prior source approval requests, and must submit their proposals within 45 days of this presolicitation notice. For further inquiries, Amanda M. Sweeney can be contacted at (215) 697-2198 or via email at AMANDA.M.SWEENEY4.CIV@US.NAVY.MIL.
