A-12
|
|||
|
|
|
|||
|
|
The A-12 was the proof-of-concept vehicle for the SR-71/YF-12 family
|
|||
|
|
of "Blackbirds." It was the 12th in a series of designs for a U-2
|
|||
|
|
replacement from Kelly Johnson's "Skunk Works," hence the designation
|
|||
|
|
"A-12." Although its operational service is shrouded in mystery, it
|
|||
|
|
is believed the single-seat A-12 was used exclusively in covert
|
|||
|
|
operations by the CIA from 1967 to 1968.
|
|||
