The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking qualified sources for the procurement of waveguide components, identified by NSN 1R-5985-015612378-E7, with a quantity of 2 each. The procurement is critical as the item is flight critical, and it requires government source approval prior to contract award, as suitable technical data or manufacturing knowledge is not available for alternative sourcing. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures to be considered, and offers that do not meet the submission requirements will not be evaluated. For further inquiries, Danielle Diciacco can be contacted at (215) 697-5970 or via email at DANIELLE.DICIACCO.CIV@US.NAVY.MIL.
