✈️ Full Specifications
The speed field uses the CIA-reported Mach 3.29 test result. The 90,000 ft (27,432 m) milestone is an attained altitude, not an independently specified service ceiling. A comparable range, dimensions, weight categories and thrust regime were not established by the cited evidence, so those numerical fields remain unknown. Production totals fifteen OXCART airframes, including one trainer and two M-21s; reconnaissance aircraft had one pilot. Operational missions began in 1967, after readiness testing in 1965.

⚔️ Armament
Overview
The Lockheed A-12 OXCART was the CIA’s single-seat, high-altitude reconnaissance aircraft. It grew out of the GUSTO competition and became the starting point for the YF-12, M-21 and SR-71 family.
Flight testing and speed
After a short hop on 25 April 1962, test pilot Lou Schalk completed a longer flight on 26 April. The official first flight followed on 30 April, witnessed by CIA and Air Force officials.
Titanium construction and the J58 propulsion system made sustained Mach 3 flight possible. Early aircraft flew with substitute J75 engines; the first flight with two J58s was on 15 January 1963. CIA’s detailed history reports Mach 3.29 and 90,000 ft as peaks reached by different aircraft in May and August 1965.
BLACK SHIELD
Three aircraft deployed to Kadena, Okinawa. From May 1967 to May 1968, BLACK SHIELD flew 29 reconnaissance missions over East Asia, including North Vietnam, North Korea, Cambodia and Laos. Photographs located the captured USS Pueblo and documented military facilities.
Production and retirement
CIA’s total of 15 OXCART aircraft includes 12 single-seat machines, one trainer and two M-21 drone carriers. Its inventory lists six accident losses, including one M-21, leaving nine airframes. The three YF-12As belong to a separate production count.
The final A-12 flight to storage took place on 21 June 1968. The SR-71 continued the reconnaissance role with a different crew and sensor arrangement; their published speeds and record flights require separate context.
Frequently Asked Questions
How fast did the A-12 fly?
CIA’s detailed history reports Mach 3.29 in 1965. The 90,000 ft altitude milestone was reached by a different aircraft; these are reported test results, not a fixed conversion to km/h.
When was the A-12’s first flight?
A short hop occurred on 25 April 1962, a longer test flight on 26 April, and the official first flight on 30 April.
Why do A-12 production totals differ?
CIA’s fifteen-aircraft total includes twelve single-seat aircraft, one trainer and two M-21 drone carriers. It excludes the three YF-12A interceptors.
Were all 29 BLACK SHIELD missions over North Vietnam?
No. The CIA mission table also includes North Korea, Cambodia and Laos. Operations ran from May 1967 to May 1968.
