A12 Single seat, built for and operated by the CIA

YF12 Prototype Interceptor built for the USAF. Two seater, only 3 built.

M12 Used for launching the D-21 Drone

SR71A Two seater built for and operated by USAF.

SR71B Two seater for pilot training.

SR71C Cut 'n Shut built from leftovers and by all accounts flew 'Orrible!

Buy a copy of Paul F crickmores' book SR71 The secret Missions Exposed ISBN 1-85532-681-7 Goes into far more detail than I can type here.

There were never that many built all told - around 50 including all variants?

[Tango13]

15 A-12s two of which were modifed into M-12s

3 YF-12s one of which became the SR-71C

29 SR-71As

2 SR71Bs

The front of a static test specimen bolted to the back of a YF-12 and designated the SR-71C

Gives a total of 49 1/2
