This is a sole-source procurement for NSN 7R-1680-014938783-V2, with a quantity of 78 units delivered FOB origin. The item is flight-critical and restricted to government-approved sources due to a lack of available technical data and data rights for competition. Only previously approved sources have been solicited, and new sources must submit a Source Approval Brochure with their proposal to be considered. Offers that fail to provide the required source approval data will not be considered for award. All responsible sources may express interest, but the government intends to negotiate with only one source under FAR 6.302-1.
