This is a sole-source supply action for 20 units of NSN 7R-1680-015854988-P8, with delivery on an FOB origin basis. The part requires engineering source approval because the approved source retains essential data rights, technical data, and manufacturing knowledge not economically available to the Government. Alternate sources must qualify in accordance with the design control activity’s procedures and obtain approval from the cognizant Government engineering activity. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, but all responsible sources may express interest and submit capability statements for consideration.
