What's the difference? Is there any beyond one being used by the USAF and the other by the CIA?

Thanks.

The A-12 was the forerunner of the SR-71.There were many differences,mostly internal,but the major difference was that the A-12 was a single-seater whereas the SR-71 was a two-seater.

The A-12 also differed substantially by having a centrally located retractable ventral fin, retractable canards, conical nose cone, and twin missiles in a tandem internal bay. These I believe were forerunners of the Phoenix missiles that now equipp the F-14.

The plane Spacepope is describing,is the YF-12 fighter derivative of the A-12.This plane was in many respects closer to the SR-71 than the A-12.

Oop sorry that's right. was the first thing that popped in my mind though. Wasn't there supposed to be an A-6 sucessor named the A-12 as well? These designations can get pretty confusing pretty quickly.

Someone once told me those air to air missles were supposed to have nuclear warheads and explode in the middle of a bomber formation. I guess when massed bomber attacks became a thing of the past there wasn't a need to develop it any further.

Yes,there was an A/C called the A-12,but in this case the A stands for Attack.It belongs to a tri-service system of A/C designations that replaced older systems in 1962,the AD Skyraider became the A-1,A4D Skyhawk became the A-4,A2F became A-6,etc.
The Lockheed A-12 was not a military designation,being a Lockheed/CIA designation meaning Article #12.I believe the U-2 also started life as an A designation,but I'm not sure.

Actually, besides the fact that the SR-71A had a systems operator in addition to the pilot, the SR-71A also had electronic intelligence/signals intelligence (ELINT/SIGINT) equipment that the original CIA A-12's lacked.

The CIA A-12's--which were flown operationally from 1964 to 1969--was limited to cameras for intelligence gathering. And they were extremely fast, too--rumors place the CIA A-12's top speed around Mach 3.5 at 85,000 feet, compared to around Mach 3.2 for the heavier SR-71A.

The U in U-2 stood for utility. In case anyone found out about it, I guess they were hoping that might fool them.

Another small fact: noone knows what SR stands for. It was originally meant to be RS (reconnaiscance/strike) but apparently someone made a mistake and the wrong designation was filed.

SR should really have been RS and stand for Strategic Reconnaissance.The number 71 is from the B for Bomber sequence.It was President Lyndon B. Johnson who mixed up the designations when he unveiled the project to the public in the mid -60's.
Having read through the previous replies to this topic,I realize I've used the designation A-12 whereas it should read A-11!This plane evolved into the F-12 fighter.
