1 May 1960: Near Degtyansk, Sverdlovsk Oblast, Russia, a Central Intelligence Agency/Lockheed U-2C, 56-6693, “Article 360,” flying at approximately 80,000 feet (24,384 meters) on a Top Secret reconnaissance mission, was hit by shrapnel from an exploding Soviet V-750VN (S-75 Desna) surface-to-air missile.

With his airplane damaged and out of control, pilot Francis Gary Powers bailed out and parachuted safely but was immediately captured. A trailing MiG-19 fighter was also shot down by the salvo of anti-aircraft missiles, and its pilot killed.

Gary Powers was interrogated by the KGB (Komitet gosudarstvennoy bezopasnosti, the Committee for State Security of the Soviet Union, a military intelligence/counterintelligence service) for 62 days. He was held at the notorious Lubyanka Prison in Moscow then prosecuted for espionage. Found guilty, Powers was sentenced to three years imprisonment and seven years of hard labor.

After almost two years, he was exchanged for William August Fisher, (AKA Rudolf Ivanovich Abel, Vilyam Genrikhovich Fisher) a long-time Soviet intelligence officer who had been captured in the United States in 1957. [This story was recounted in the Steven Spielberg motion picture, “Bridge of Spies,” which starred Tom Hanks. The film received six Academy Award nominations in 2015.]

Francis Gary Powers entered the United States Air Force as an aviation cadet in 1950. He graduated from pilot training and was commissioned a second lieutenant in 1952. Powers was then assigned to the 468th Strategic Fighter Squadron, 506th Strategic Fighter Wing at Turner Air Force Base, Georgia, where he flew the Republic F-84G Thunderjet fighter bomber. He received special training in the delivery of the Mark 7 variable-yield tactical nuclear bomb.

In 1956, 1st Lieutenant Powers was released from the U.S. Air Force to participate in the Central Intelligence Agency’s Project Aquatone. He was now a civilian government employee, although he was promised that he could return to the Air Force and that he would keep his seniority and would be promoted on schedule.

After his release from the Soviet Union, Powers was employed as a test pilot for Lockheed, 1962–1970. He then became an airborne traffic and news reporter for several Los Angeles-area radio and television broadcast stations.

Powers was killed in the crash of a Bell 206B JetRanger helicopter at Van Nuys, California, 1 August 1977.

On 24 November 1986, the Distinguished Flying Cross was awarded posthumously to Powers “For Extraordinary Achievement While Participating in Aerial Flight 1 May 1960.”

After reviewing his record at the request of his son, Francis Gary Powers, Jr., on 15 February 2000, the U.S. Air Force retroactively promoted him to the rank of Captain, effective 19 June 1957, and further credited his military service to include 14 May 1956–1 March 1963, the time he was with the CIA. The award of the Prisoner of War Medal was also authorized.

On June 15, 2012, General Norton Schwartz, Chief of Staff of the Air Force, awarded Captain Francis Gary Powers the Silver Star (posthumous).

Article 360 had been built as a U-2A, the last aircraft of the initial production block. It was delivered to Groom Lake, Nevada, 5 November 1956, and was used for test and development until May 1959, when it was converted to the U-2C configuration.

The Lockheed U-2C was a very high-altitude reconnaissance aircraft used by the U.S. Central Intelligence Agency and the United States Air Force. It was 49 feet, 7 inches (15.113 meters) long with a wingspan of 80 feet, 2 inches (24.435 meters) and height of 15 feet, 2 inches (4.623 meters). Its empty weight was 14,250 pounds (6,464 kilograms) and gross weight was 24,150 pounds (10,954 kilograms).

The U-2C was powered by a Pratt & Whitney J75-P-13B turbojet engine rated at 17,000 pounds of thrust (75.62 kilonewtons) at Sea Level. Two-spool axial-flow turbojet with 15-stage compressor (8 low- and 7 high-pressure stages) and 3-stage turbine (1 high- and two low-pressure stages).

The U-2C’s cruise speed was 400 knots (460 miles per hour, 741 kilometers per hour) at 65,000 feet (19,812 meters) and its maximum speed was 0.87 Mach at 62,000 feet (18,898 meters), though the airplane was placarded for 0.80 Mach, maximum. The maximum range was 4,600 nautical miles (8,519 kilometers). It could operate at 76,000 feet (23,165 meters).

The В-750ВН (13Д) Десна (V-750VN 13D Desna) (NATO designation: SA-2B Guideline) is a two-stage ground-controlled anti-aircraft missile. The two-stage rocket is 10.841 meters (35 feet, 6.8 inches) long, and its loaded weight is 2,283 kilograms (5,033 pounds). First built at Plant N41, it became operational in 1959.

The missile could reach an altitude of 30,000 meters (98,425 feet) and had a maximum range of 34 kilometers (21 miles). It carried a 191 kilogram (421 pound) blast fragmentation warhead.

The missile had a Circular Error Probability (CEP) of 65 meters (213 feet), meaning that 50% of the missiles launched could be expected to come within 65 meters of the target. Early warheads produced approximately 8,000 fragments, each with an initial velocity of 2,500 meters per second (5,592 miles per hour). The maximum blast radius against a high altitude target was about 250 meters (820 feet).

The rocket’s first stage had a maximum diameter of  0.654 meter (2 feet, 3.6 inches) and fin span of 2.586 meters (8 feet, 5.8 inches). It was powered by a solid fuel Kartukov PRD-18 engine. The engine burned for 3–5 seconds and produced a maximum 455 kilonewtons (102,288 pounds) of thrust.

The second stage was 8.139 meters (26 feet, 8.4 inches) long with a maximum diameter of 0.500 meters (1 foot, 7.7 inches). The maximum fin span was 1.691 meters (5 feet, 6.6 inches). Its loaded weight was 1,251 kilograms (2,758 pounds). The second stage was powered by a C2.711B1 (S2.711V1) hypergolic liquid-fueled rocket engine which produced 30.4 kilonewtons (6,834 pounds) of thrust.

30 April 1962

"Article 121" takes off on its first flight at Groom Lake, Nevada, 30 April 1962. (Lockheed Martin)

30 April 1962: Though it had been airborne briefly just a few days earlier, “Article 121”, the first Lockheed A-12, serial number 60-6924, took off from a Top Secret facility at Groom Lake, Nevada, on its “official” first flight. Lockheed test pilot Louis Wellington (“Lou”) Schalk, Jr. was in the cockpit.

The 72,000-pound (32,659 kilogram) airplane lifted off the 8,000-foot (2,438 meters) runway at 170 knots (196 miles per hour, 315 kilometers per hour).

During the 59-minute test flight, Schalk kept the airspeed to just 340 knots (391 miles per hour, 630 kilometers per hour), but climbed to 30,000 feet (9.144 meters) while he tested systems and handling characteristics. He described the airplane as very stable and extremely responsive.

The A-12 was a top secret reconnaissance airplane built for the Central Intelligence Agency under the code name “Oxcart.” It was the replacement for the Agency’s high-flying but subsonic U-2 spy plane which had become vulnerable to radar-guided surface-to-air missiles. (A U-2 piloted by Francis Gary Powers had been shot down with an SA-2 Guideline missile while over Russia exactly one year before.)

The A-12 could fly faster than Mach 3 and higher than 80,000 feet—so fast and so high that no missile could reach it. By the time missile site radar locked on to an A-12 and a missile was prepared to fire, the Oxcart had already flown beyond the missile’s range.

The Lockheed A-12 was a single-place, twin-engine hypersonic reconnaisance aircraft. It was 101.6 feet (30.97 meters) long, with a wingspan of 55.62 feet (16.95 meters) and overall height of 18.45 feet (5.62 meters). It had an empty weight of 54,600 pounds (24,766 kilograms) and maximum gross weight of 124,600 pounds (57,878 kilograms).

The A-12 was powered by two Pratt & Whitney JT11D-20 (J58-P-4) turbo-ramjet engines, rated at 25,000 pounds of thrust (111.21 kilonewtons) and 34,000 pounds of thrust (151.24 kilonewtons) with afterburner. The exhaust gas temperature is approximately 3,400 °F. (1,870 °C.). The J58 is a single-spool, axial-flow engine which uses a 9-stage compressor section and 2-stage turbine. The J58 is 17 feet, 10 inches (7.436 meters) long and 4 feet, 9 inches (1.448 meters) in diameter. It weighs approximately 6,000 pounds (2,722 kilograms).

The A-12’s speed was Mach 3.2 (2,125 miles per hour/3,118 kilometers per hour) at 75,000 feet(22,860 meters). Its cruise altitude was 84,500–97,600 feet (25,756–29,748 meters). The range was 4,210 nautical miles (4,845 miles/7,797 kilometers)

Article 121 was the first of thirteen A-12s built by Lockheed’s “Skunk Works.” They were operational from 1964–1968, when they were phased out in favor of the U.S. Air Force two-man SR-71A “Blackbird.”

Today, the first Lockheed A-12 is on display at Blackbird Airpark, an annex of the Air Force Flight Test Museum, Edwards Air Force Base, California. It has made 322 flight and accumulated a total of 418.2 flight hours.

26 April 1962

26 April 1962: At a non-existent location in the Mojave Desert of Nevada, Lockheed Chief Test Pilot Louis Wellington (“Lou”) Schalk, Jr., was scheduled to take the first Oxcart for a high-speed taxi test on the specially constructed 8,000-foot (2.44 kilometer) runway. However, he had received secret, specific instructions from designer Kelly Johnson to take the craft, known as “Article 121,” airborne.

Lou Schalk roared down the runway and lifted off. He flew at about 20 feet for two miles. The super-secret aircraft was oscillating badly so he set it down straight ahead on the dry lake bed and disappeared into a cloud of dust and flying sand. Johnson said that it “was horrible to watch.” A few minutes later, the needle nose of Article 121 appeared out of the dust as Schalk taxied back to the runway. It turned out that some equipment had been hooked up backwards. Subsequent flights were made without difficulty.

This was the actual first flight of the Central Intelligence Agency’s Top Secret A-12 reconnaissance aircraft. The “official” first flight would come several days later.

Designed as the successor to the Agency’s subsonic U-2 spy plane, the twin-engine  jet was capable of flying more than Mach 3 (over 2,000 miles per hour/3,218.7 kilometers per hour) and higher than 80,000 feet (24,384 meters). Built by Lockheed’s “Skunk Works,” the new airplane wasn’t “state of the art,” it was well beyond the state of the art. New materials were developed. New equipment designed and built. New manufacturing processes were invented.

The A-12, developed under the code name “Oxcart,” was unlike anything anyone had ever seen. The first A-12 was referred to as Article 121. “A” = “Article.” “12-” is for A-12. “-1” is for the first production aircraft. So you get “Article 121.” What could be simpler?

The A-12 was so fast and could fly so high that it was invulnerable to any defense. No missile or aircraft or gun could reach it.

Thirteen A-12s were built for the CIA.  Two M-21 variants, built to carry the Mach 4 D-21 drone, were also produced. An interceptor version was developed for the Air Force as the YF-12A.

Ninety-three Lockheed F-12B interceptors were ordered though Secretary of Defense Robert S. McNamara  refused to release the funding for production. After three years, the order was cancelled. The Air Force liked the A-12, however, and ordered 32 of the more widely known two-place SR-71A “Blackbird” reconnaissance ships.

Today, Article 121 is on display at the Blackbird Airpark, an annex of the Air Force Flight Test Museum, Edwards Air Force Base, California.

20–21 April 1964: Nearly ten years after the first flight of the Lockheed YC-130 Hercules prototype, the Lockheed Model 382, serial number 3946, the commercial version of the military C-130E, made the longest first flight in history when it flew for 25 hours, 1 minute, after taking off from Marietta, Georgia.

The flight crew, led by Chief Production Pilot Joe Garrett, flew the Hercules in a racetrack pattern over Georgia and Alabama, and for all but 36 minutes of the flight, the outboard engines were shut down and their propellers feathered.

The Lockheed Model 382 was certified by the Federal Aviation Administration 16 February 1965.

The L-382 was powered by four Allison 501-D22 turboprop engines, rated at 3,755 shaft horsepower at 13,820 r.p.m., and driving four-bladed Hamilton Standard Hydromatic constant-speed, reversible-pitch propellers with a diameter of 13 feet, 6 inches (4.115 meters). at 1,020 r.p.m.

Maximum operating altitude 32,600 feet (9.936 meters)

N1130E was retained by Lockheed as a demonstrator, however it was briefly leased to Alaska Airlines in March 1965, and returned the following month.

The L-382 was converted to the L382E-44K-20 standard in April 1968, with a 5 foot, 0 inch (1.524 meters) segment added to the fuselage behind the cockpit, and a 3 foot, 4 inch (1.016 meter) section behind the wing.

N1130E was leased to Delta Air Lines in October 1968, and returned after six months.

Lockheed sold N1130E to Pepsico Airlease Corporation, who leased the freighter to Flying W Airways. It was reregistered as N50FW. In March 1973 Pepsico sold it to Philippine Aerotransport and it was operated for the Philippine government, first as PI-97, and then RP-97.

16 April 1949: At Van Nuys Airport, California, test pilot Tony LeVier and flight test engineer Glenn Fulkerson made the first flight of the Lockheed YF-94 prototype, serial number 48-356. The aircraft was the first jet-powered all-weather interceptor in service with the United States Air Force and was the first production aircraft powered by an afterburning engine.

Two prototypes were built at Lockheed Plant B-9, located on the east side of Van Nuys Airport. Two TF-80C-1-LO (later redesignated T-33A) Shooting Star two-place trainers, 48-356 and 48-373, were modified with the installation of air intercept radar, an electronic fire control system, radar gun sight, four Browning AN-M3 .50-caliber (12.7 × 99 NATO) aircraft machine guns and a more powerful Allison J33-A-33 turbojet engine with water-alcohol injection and afterburner. The rear cockpit was equipped as a radar intercept officer’s station.

It was initially thought that the project would be a very simple, straightforward modification. However, the increased weight of guns and electronics required the installation of a more powerful engine than used in the T-33A. The new engine required that the aft fuselage be lengthened and deepened. Still, early models used approximately 80% of the parts for the F-80C fighter and T-33A trainer. The Air Force ordered the aircraft as the F-94A. Improvements resulted in an F-94B version, but the definitive model was the all-rocket-armed F-94C Starfire.

The Allison J33-A-33 was a single-shaft turbojet engine with a single-stage centrifugal-flow compressor, 14 combustion chambers and, a single-stage axial flow turbine. The engine was rated at 4,600 pounds of thrust (20.46 kilonewtons) and 6,000 pounds (26.69 kilonewtons) with afterburner. The J33-A-33 was 17 feet, 11.0 inches (5.461 meters) long, 4 feet, 1.3 inches (1.252 meters) in diameter and weighed 2,390 pounds (1,084 kilograms).

Originally a P-80C Shooting Star single-place fighter, 48-356 had been modified at Lockheed Plant B-9 in Van Nuys to become the prototype TF-80C two-place jet trainer (the designation was soon changed to T-33A), which first flew 22 March 1948. It was then modified as the prototype YF-94. 48-356 was later modified as the prototype F-94B. It is in the collection of the Air Force Flight Test Museum, Edwards Air Force Base, and is in storage awaiting restoration.
