7 July 1962: Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union, flew the Mikoyan-Gurevich E-152\1 to a two-way average speed of 2,681 kilometers per hour (1,666 miles per hour), setting a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course.¹

The E-152\1 (also known as Ye-152-1) was a prototype interceptor, similar to the production MiG-21. In documents submitted to FAI, the E-152\1 was identified as E-166. Colonel Mosolov made the first flight of the E-152\1 on 21 April 1961. The aircraft displayed at The Central Museum of the Air Forces at Monino, Russia, as E-166 is actually the E-152\2, sister ship of Colonel Mosolov’s record-setting prototype.

This airplane set two other FAI world records. Test Pilot Alexander Vasilievich Fedotov flew it to 2,401 kilometers per hour (1,492 miles per hour) over a 100 kilometer course, 10 October 1961; ² and on 11 September 1962, Pyotr Maksimovich Ostapenko set a world record for altitude in horizontal flight of 22,670 meters (74,377 feet feet).³

The Mikoyan Gurevich E-152\1 is a single-place, single-engine delta-winged prototype all-weather interceptor. It is 19.656 meters (64.448 feet) long  with a wingspan of 8.793 meters (28.848 feet). The leading edge of the wings are swept back to 53° 47′. The empty weight is 10,900 kilograms (24,030 pounds) and takeoff weight is 14,350 kilograms (31,636 pounds).

It was powered by a Tumansky R-15B-300 turbojet engine producing 22,500 pounds of thrust (100.085 kilonewtons) with afterburner. This was the original engine for the MiG-25.

Maximum speed Mach 2.82 (3,030 kilometers per hour, 1,883 miles per hour) at 15,400 meters (50,525 feet). The service ceiling is 22,680 meters (74,405 feet). Internal fuel capacity is 4,960 liters (1,310 gallons), and the E-152\1 could carry a 1,500 liter (396 gallon) external fuel tank. Its range is 1,470 kilometers (913 miles).

After a two-year test program, E-152\1 and its sistership, E-152\2 were converted to E-152M\1 and E-152M\2.

Georgy Konstantinovich Mosolov was born 3 May 1926 at Ufa, Bashkortostan, Union of Soviet Socialist Republics. He was educated at the Central Aviation Club, where he graduated in 1943, and then went to the Special Air Forces School. In 1945 he completed the Primary Pilot School and was assigned as an instructor at the Chuguev Military Aviation School at Kharkiv, Ukraine.

In 1953 Mosolov was sent to the Ministry of Industrial Aviation Test Pilot School at Ramenskoye Airport, southeast of Moscow, and 6 years later, to the Moscow Aviation Institute. He was a test pilot at the Mikoyan Experimental Design Bureau from 1953 to 1959, when he became the chief test pilot.

Georgy Mosolov set six world speed and altitude records. He was named a Hero of the Soviet Union, 5 October 1960, and Honored Test Pilot of the Soviet Union, 20 September 1967. The Fédération Aéronautique Internationale awarded him its Henry De La Vaulx Medal three times: 1960, 1961 and 1962. The medal is presented to the holder of a recognized absolute world aviation record, set the previous year.

On 11 September 1962, an experimental Mikoyan Ye-8 that Colonel Mosolov was flying suffered a catastrophic compressor failure at Mach 2.15. Engine fragments heavily damaged to prototype and it began to break apart. Severely injured, Mosolov ejected from the doomed airplane at Mach 1.78. He had suffered a severe head injury, two broken arms and a broken leg during the ejection and became entangled in the parachute’s shroud lines. His other leg was broken when he landed in a forest. The following day he suffered cardiac arrest. During a surgical procedure, he went in to cardiac arrest a second time.

Mosolov survived but his test flying career was over. His recovery took more than a year, and though he was able to fly again, he could not resume his duties as a test pilot.

Georgy Mosolov served as an international representative for Aeroflot until 1992. He was also a department head at the Higher Komsomol School (Moscow University for the Humanities).

Mosolov was Chairman of the USSR Hockey Federation from 1969 to 1973. He was an Honored Master of Sports of the USSR.

Colonel Georgy Konstantinovich Mosolov, Soviet Air Forces, Hero of the Soviet Union, died 17 March 2018, at Moscow, Russia, at the age of 91 years. He was buried at the Vagankovsoye cemetery in Moscow.
