Three MiG-25RB reconnaissance/strike aircraft were also modified with the R15BF2-300, which were used to set a series of time-to-height world records (under the designation Ye-266M) on 17 May 1975, and two altitude world records in 1977.

May 28, 2009 · On July 17, 1962, American test pilot Robert White took the X-15 to an altitude of 314,688 feet. But it’s Russian pilot Alexandr Fedotov who holds the world altitude record, set on August 31, 1977,...

Aug 31, 2017 · To establish that record, Fedotov flew an experimental MiG-25 fighter. The aircraft was actually a MiG-25RB re-engined with the powerful R15BF2-300. Flying this aircraft he reached the record height of 123,523 feet above Podmoskovnoe, Russia.

The official FAI (Fédération Aéronautique Internationale) altitude record is 37,650 m (123,523 ft), by Alexandr Fedotov (USSR) flying a highly modified MIG-25 'Foxbat' (designated E266M) from Podmoskovnoe Aerodrome, Russia, on 31 August 1977. The altitude was reached during a near-vertical climb. See also Highest altitude in horizontal flight.

Apr 7, 2024 · SR-71 & MiG E-266M disputed the record for the highest flights, set during the Cold War in the '60s and '70s. U.S. military aircraft can go above 50,000 feet, while the U2 & MiG-31 have the highest service ceilings.

A.Fedotov and P.Ostapenko in 1975 on the MiG-25RB #601, which in protocols of the FAI was known as E-266M with RD-F engines, put up three world records in speed-climbing to 25, 30 and 35 km altitude.

While the MiG-25 was hella fast to begin with, the E-266M was even more optimized for speed and altitude. It still to this day holds the absolute altitude world record for an air breathing jet aircraft, at 37,650 meters (123,524 ft) set in 1977.
