This is a one-source-intent procurement under FAR 6.302-1 for NSN 7R-4820-014729777-KB, TDP VER 002, quantity 10 EA, 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 contract award and only previously approved sources have been solicited. New sources must submit the source-approval information required by the applicable NAVSUP WSS Source Approval Information Brochure with their offer; offers missing required data or prior submission documentation will not be considered. If a new-source approval cannot be processed in time, award may proceed based on Fleet support needs, while responsible sources may still identify interest and capability or submit proposals, quotations, or capability statements.
