Lockheed A-12 Oxcart
Lockheed (Skunk Works) · Strategic Reconnaissance · USA · Early Jet (1946–1969)
The Lockheed A-12 Oxcart was the CIA's single-seat strategic reconnaissance aircraft and the direct ancestor of the better-known SR-71 Blackbird. Designed by Kelly Johnson at Lockheed's Skunk Works as the successor to the subsonic U-2 after Francis Gary Powers was shot down over the Soviet Union in 1960, the A-12 first flew in April 1962 and entered CIA service in 1963. Thirteen single-seat A-12s were built — fewer than any other Blackbird variant — alongside two M-21 drone-launcher derivatives and three YF-12A interceptor prototypes. Compared with the SR-71, the A-12 was lighter, slightly faster (Mach 3.35 demonstrated), and could fly slightly higher (over 90,000 ft), though with shorter range and no second-crewman station for navigation and sensor operations.
Operating from a remote base at Groom Lake, Nevada — the same facility now better known as Area 51 — A-12s flew under the codename Project OXCART. The aircraft used the same Pratt & Whitney J58 turbo-ramjets, titanium-dominant airframe, and chined fuselage as the SR-71 because the SR-71 was, in essence, an enlarged A-12. CIA pilots flew 29 operational missions over North Vietnam and North Korea between May 1967 and May 1968 from Kadena Air Base, Okinawa, including the famous overflight that confirmed the location of the captured USS Pueblo.
President Lyndon Johnson's January 1968 decision to retire the A-12 in favour of the USAF's two-seat SR-71 ended the CIA programme just as it had reached operational maturity. The A-12 fleet was placed in storage at Palmdale, California, in June 1968. Of the 15 airframes built (13 A-12s plus 2 M-21s), six were lost in accidents during the programme; the nine survivors are now displayed at museums including the Smithsonian's Udvar-Hazy Center, the CIA Headquarters at Langley, Birmingham (Alabama) Southern Museum of Flight, and the USS Intrepid in New York. The A-12's existence was not officially declassified by the CIA until 2007.
For Kids — a shorter, friendlier version
The Lockheed A-12 Oxcart was a super-fast spy plane built for the CIA. It could fly faster than three times the speed of sound. That means it was faster than a rifle bullet! Only thirteen of these amazing jets were ever made.
The A-12 was designed by an engineer named Kelly Johnson at a secret team called Skunk Works. It first flew in April 1962 and started flying spy missions in 1963. Pilots flew it from a secret base in Nevada called Groom Lake, which most people now call Area 51.
The plane could fly higher than 90,000 feet. That is nearly 17 miles above the ground! At that height, the sky looks almost black. No enemy plane could reach it up there.
The A-12 was the parent of the famous SR-71 Blackbird. The SR-71 was basically a bigger version of the A-12. The A-12 was smaller than the SR-71 and had only one seat instead of two. It was also slightly faster than its famous cousin.
CIA pilots flew 29 spy missions over North Vietnam and North Korea in the A-12. The program ended in 1968. Today the A-12 is remembered as one of the greatest spy planes ever built.
Fun Facts
- The A-12 Oxcart could fly faster than three times the speed of sound!
- It flew from Area 51, one of the most secret bases in the world.
- Only 13 A-12s were ever built, fewer than any other Blackbird-family jet.
- The A-12 could soar higher than 90,000 feet — nearly 17 miles up!
- The A-12 was smaller than the SR-71 Blackbird, which was built from the same basic design.
- Its body was made mostly from titanium, a super-strong and heat-resistant metal.
- CIA pilots flew 29 scouting missions in the A-12 over enemy territory.
- The A-12 used special jet engines called turbo-ramjets to reach its incredible speed.
Kids’ Questions
What made the A-12 so fast?
The A-12 used powerful engines called turbo-ramjets made by Pratt and Whitney. Its sleek, pointed body helped it cut through the air at amazing speeds. It could reach faster than three times the speed of sound!
Why did the CIA need a spy plane like the A-12?
The CIA needed a plane that could fly so high and so fast that no one could bring it down. An earlier spy plane called the U-2 was destroyed over the Soviet Union in 1960. The A-12 was built to be much harder to catch.
How is the A-12 different from the SR-71 Blackbird?
The A-12 had only one seat, while the SR-71 had two. The A-12 was also lighter and slightly faster than the SR-71. The SR-71 was basically a larger version of the A-12.
Where did A-12 pilots fly their missions?
A-12 pilots flew their scouting missions over North Vietnam and North Korea. They flew 29 missions in total. The planes took off from a secret base in Nevada called Groom Lake, also known as Area 51.
Variants
- A-12
- Single-seat CIA reconnaissance aircraft, 13 built. The base variant that flew operational missions over North Vietnam and North Korea.
- M-21
- Two-aircraft drone carrier modified to launch the D-21 reconnaissance drone. One was lost in a fatal launch accident in 1966.
- YF-12A
- Three-aircraft interceptor prototype with AIM-47 missiles. Set speed and altitude records in 1965 before the programme was cancelled.
Notable Operators
- Central Intelligence Agency (1963–1968)
- Operated under codename Project OXCART from Groom Lake, Nevada and Kadena AB, Okinawa. Flew 29 operational reconnaissance missions before the type was retired.
Frequently Asked Questions
What is the difference between the A-12 and the SR-71?
The A-12 was a single-seat CIA aircraft (13 built); the SR-71 was a larger two-seat USAF aircraft (32 built). The A-12 was slightly faster (Mach 3.35 vs 3.2) and higher (90,000+ ft vs 85,000 ft), but the SR-71 had longer range, a sensor operator station, and a much larger payload bay. The SR-71 replaced the A-12 in 1968.
How fast was the A-12 Oxcart?
The A-12 demonstrated Mach 3.35 in flight tests, faster than the operational SR-71's Mach 3.2 cruise. Its lighter weight gave it both higher altitude and slightly higher top speed than the Air Force variant.
Where did the A-12 fly from?
The A-12 flew from Groom Lake (Area 51) in Nevada for testing and training, and from Kadena Air Base in Okinawa for operational missions over North Vietnam and North Korea between 1967 and 1968.
Was the A-12 ever shot down?
No A-12 was ever lost to enemy action. Six of the 15 airframes built were lost to accidents during testing and operations, but the type was never successfully intercepted.
