The SR-71 Blackbird

The CIA A-12 Blackbird Program

 

The A-12 started out as an USAF interceptor to replace the cancelled F-108A Rapier. In October 1962, CIA authorized the Skunk Works to study the feasibility of modifying the A-12 to carry and deploy a reconnaissance drone for unmanned overflight of denied areas. The project was codenamed TAGBOARD.
