This requirement is for a flight-critical item, quantity 2, with delivery FOB origin. The part requires Government source approval, and only previously approved sources have been solicited. Any new source must submit the data required by the NAVSUP WSS Source Approval Information Brochure, or the offer will not be considered. Approval of a new source cannot normally be delayed, so award may proceed based on fleet support needs even if approval requests are pending. No budget amount or specific performance location is provided.
