The Government is seeking a commercial/nondevelopmental/off-the-shelf, flight-critical part for a quantity of 5 each, with delivery FOB origin. The item requires Government source approval prior to contract award, so only previously approved sources have been solicited. If you are not an approved source, you must submit the required source approval information with your proposal per the applicable NAVSUP WSS Source Approval Information Brochure for Spares or Repair, or document prior submission of that data. Offers missing the required source approval data will not be considered for award. Because approval of a new source may not be completed in time to meet Government requirements, award may proceed based on Fleet support needs.
