This is a non-competitive, sole-source procurement for 14 parts requiring delivery to distribution centers in Pennsylvania and California. The Government intends to negotiate with only one approved source due to existing unique design capability, essential data rights, and the need to maintain part quality. However, the notice allows other sources to identify their capability within 45 days for potential consideration. Interested parties may also identify commercial item alternatives within 15 days. An alternate source must qualify through specific procedures approved by the cognizant Government engineering activity.
