This opportunity is for the acquisition of 13 units of a part (NSN 0R-7025-017061785-H1) with an unstable design, as major changes are anticipated that will render the current configuration obsolete. Delivery is FOB Origin, and the item requires Government source approval prior to award due to its flight-critical nature. Only previously approved sources have been solicited, and new sources must submit detailed technical data as outlined in the NAVSUP WSS Source Approval Information Brochures with their proposal. The Government intends to negotiate with only one source under FAR 6.302-1, but all responsible sources may submit proposals within 45 days of this synopsis. No specific budget amount or performance location is mentioned.
