This opportunity is for the acquisition of 11 units of NSN 0Q-5940-017216317-V2, a part with an unstable design that is expected to become obsolete due to planned major changes. Delivery is FOB Origin, and the item requires Government source approval prior to award because it is flight critical. Only previously approved sources have been solicited, and new sources must submit detailed technical data as outlined in the NAVSUP WSS Source Approval Brochure with their proposal. Proposals from non-approved sources that fail to provide all required data will not be considered, and the Government intends to negotiate with only one source under FAR 6.302-1. The location for performance of services is not specified, and no budget amount is provided.
