The requirement is for 12 each of NSN 7R-1680-014803449-QE, TDP VER 001, delivered FOB origin. The item is flight critical and/or lacks adequate technical data for full and open competition, so Government source approval is required before award, only previously approved sources have been solicited, and new-source approval normally cannot delay award. If you are not an approved source, you must submit the information detailed in the applicable NAVSUP WSS Source Approval Information Brochure (Spares or Repair) with your proposal; offers missing required data will not be considered. The Government intends to solicit and negotiate on a sole-source basis under FAR 6.302-1, though responsible sources may identify their interest and capability or submit proposals, quotations, or capability statements. This is not a request for competitive proposals, FAR Part 12 commercial-item policies are not being used, and interested parties may identify commercial-item capability to the contracting officer.
