28 April 1961: Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union, flew a prototype Mikoyan-Gurevich MiG-21F interceptor, the Ye-6T/1, 31 Red, to a Fédération Aéronautique Internationale (FAI) World Record for Altitude of 34,714 meters (113,891 feet).¹ This exceeded the record set five months earlier by Captain Joe B. Bailey, U.S. Air Force, with a Lockheed F-104C Starfighter, by 3,201 meters (10,502 feet). ²

The Ye-6T/1 and Ye-6T/3 were converted from the first and third MiG-21F prototypes. These experimental airplanes were built to test various missiles, engines and canard/wing configurations.

Ye-6T/1 was powered by a Tumansky R-11F2-300 afterburning turbojet engine and carried a liquid-fueled Sevruk S3-20M5A rocket engine mounted under the fuselage. The rocket produced 29.42 kilonewtons (6,614 pounds of thrust) at Sea Level. The prototype carried sufficient rocket fuel for 100 seconds burn time.

Mosolov set two world speed records with the Ye-6T/1 on 31 October 1959, with a performance of 2,388.00 kilometers per hour over a straight 15/25 kilometer course ³, and a 100 kilometer closed course.⁴

Major General Vladimir Konstantinovich Kokkinai had also set a world speed record with 31 Red. On 16 September 1960, Kokkinaki flew the Ye-6T/1 to 2,148.66 kilometers per hour (1,335 miles per hour) around a 100 kilometer closed course.⁵

Ye-6T/1 and Ye-6T/3 became the prototypes for the MiG-21-F-13 short range supersonic interceptor (NATO designation: Fishbed-C)

The Микоян и Гуревич МиГ-21-Ф-13 (Mikoyan-Gurevich MiG-21F-13) is a short-range supersonic interceptor with a “tailed-delta” configuration. The MiG-21-F-13 is 13.46 meters (44 feet,  1.9 inches) long, with a wingspan of 7.154 meters (23 feet, 5.7  inches), and height of 4.71 meters (15 feet, 5.4 inches). It has an empty weight of 4,871 kilograms (10,739 pounds), and a normal takeoff weight of 7,100 kilograms (15,653 pounds).

The MiG-21-F-13 was powered by a single Tumansky R-11F-300 engine. This is a dual-spool, axial-flow turbojet with afterburner,. It has a 6-stage compressor section (3 low- and 3 high-pressure stages) and a 2-stage turbine (1 high- and 1 low-pressure stage). The R-11F-300 is rated at 8,600 pounds of thrust (38.26 kilonewtons), and 11,200 pounds (49.82 kilonewtons) with afterburner.

The MiG-21-F-13 had a maximum speed of 1,200 kilometers per hour (746 miles per hour) at Sea Level, and 2,175 kilometers per hour (1,351 miles per hour) at high altitude. It could reach its service ceiling of 19,000 meters (62,334 feet) in just over 13 minutes. Its range is 1,300 kilometers (808 miles).

The -F-13 was armed with one Nudelman-Rikhter NR-30 30 mm autocannon with 30 rounds of ammunition, and two Vympel R-3S infrared-homing air-to-air missiles (NATO: AA-2A Atoll).

Colonel Georgy Konstantinovich Mosolov, Hero of the Soviet Union

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.

15 December 1959: At Edwards Air Force Base, California, Major Joseph William Rogers, United States Air Force, flew a Convair F-106A Delta Dart all-weather interceptor, serial number 56-0467, to a new Fédération Aéronautique Internationale (FAI) World Record for Speed over a 15 Kilometer-to-25 Kilometer Straight Course, breaking the record set two years earlier by Major Adrian E. Drew with a modified McDonnell F-101A Voodoo.¹

At an altitude of 40,000 feet (12,192 meters), Rogers made two passes over the straight 11 mile (17.7 kilometers) course, once in each direction, for an average speed of 2,455.736 kilometers per hour (1,525.924 miles per hour)—Mach 2.31. For his accomplishment, he was awarded the Distinguished Flying Cross, the FAI’s Henry De La Vaulx Medal, and the Thompson Trophy.

Major Rogers was the Air Force F-106 project officer assigned to Convair. He first attempted the record with another F-106A, 56-0459, but when that Delta Dart developed uncontrollable compressor stalls, 56-0467 was substituted. (This has led to confusion over which aircraft actually set the record, but in an interview, Colonel Rogers confirmed that it was 467.)

Joseph William Rogers was born at Chillicothe, Ohio, 28 May 1924. He grew up on a farm, and attended West High School, graduating in 1942. He enlisted in the U.S. Army Air Corps in 1943 and trained as a pilot. From 1944 he was assigned as a flight instructor in California. Rogers remained in the Air Force after World War II.

During the Korean War, Joe Rogers got the nickname “Whistlin’ Joe” when he put whistles on the wings of his North American Aviation F-51D Mustang in an effort to frighten enemy troops. 1st Lieutenant Rogers was awarded the Silver Star for his actions of 8 October 1950, in close support of a British infantry unit, which was surrounded on a hilltop by the enemy.

Though not officially credited, it is widely accepted that on 8 November 1950, with his Mustang Buckeye Blitz VI, he shot down an enemy Mikoyan-Gurevich MiG-15 jet fighter. An aerial victory of a piston-engine fighter over a jet fighter was a very rare occurrence. Rogers was one of a group of “The American Fighting Man” named Man of the Year by TIME Magazine. He flew 170 combat missions in the F-51 and another 30 in the Lockheed F-80 Shooting Star.

Rogers was a 1954 graduate of the Air Force Test Pilot School and worked as a test pilot on the North American Aviation F-86D Sabre radar-equipped interceptor, and then the Convair F-102 Delta Dagger and F-106 Delta Dart.

From 1960 to 1964 Rogers commanded the 317th Fighter Interceptor Squadron at Elmendorf Air Force Base, Alaska, which was, at that time, the largest squadron in the United States Air Force. In 1963, he flew a F-102 in the annual William Tell competition at Tyndall Air Force Base, Florida, which he won, and was named the Air Force’s “Top Gun.”

Next Rogers he commanded the Lockheed SR-71A and F-12A Test Force at Edwards Air Force Base. He is one of the few pilots to have ejected from an SR-71A, when 61-7953 went out of control, 18 December 1969. Both he and Radar Intercept Officer Lieutenant Colonel Gary Heidelbaugh safely escaped the doomed Blackbird.

Colonel Rogers was Vice Commander of the 3d Fighter Wing, flying the McDonnell F-4 Phantom II during the Vietnam War. After serving as Assistant Deputy Commander of the 7th and 13th Air Forces, he was appointed Chief of Staff for Operations at the Aerospace Defense Command Headquarters, Peterson Air Force Base, Colorado. Rogers retired from the Air Force in 1975 after 32 years of service.

Joe Rogers worked for Northrop Aerospace for the next 13 years, marketing the company’s F-5 and F-20 fighters.

During his service in World War II, the Korean War and the Vietnam War, Colonel Rogers was awarded the Silver Star, the Legion of Merit with two Oak Leaf Clusters, Distinguished Flying Cross with two Oak Leaf Clusters, and Air Medal with thirteen Oak Leaf Clusters.

Joe Rogers was married to the former Charis Tate. They had three children. Mrs. Rogers passed away in 2003.

Colonel Joseph W. Rogers died at Healdsburg, California, 6 August 2005, at the age of 81 years. He is buried at Arlington National Cemetery, alongside his wife.

The Convair F-106A Delta Dart was the primary all-weather interceptor of the United States Air Force from 1959 to 1988, when it was withdrawn from service with the Air National Guard. It was a single-seat, single engine delta-winged aircraft capable of speeds above Mach 2. The airplane was a development of the earlier F-102A Delta Dagger, and was initially designated F-102B. However, so many changes were made that it is considered to be a new aircraft.

The F-106A is 70 feet, 8¾ inches (21.558 meters) long with a wingspan of 38 feet, 4 inches (11.684 meters). The top of the vertical fin was 20 feet, 3¼ inches (6.179 meters) high. The Delta Dart weighs 24,646 pounds (11,179 kilograms) empty, 35,500 pounds (16,103 kilograms) gross, andhas a maximum takeoff weight (MTOW) of 41,831 pounds (18,974 kilograms).

The F-106 was powered by a Pratt & Whitney J75-P-17 afterburning turbojet engine. The J75-P-17 was a two-spool axial-flow turbojet engine with afterburner. It used a 15-stage compressor section (8 high- and 7 low-pressure stages) and a 3-stage turbine section (1 high- and 2-low pressure stages. The J75-P-17 was rated at 16,100 pounds of thrust (71.62 kilonewtons) 24,500 pounds (108.98 kilonewtons) with afterburner. The engine was 3 feet, 7.0 inches (1.092 meters) in diameter, and weighed 5,875 pounds (2,665 kilograms)

The interceptor has a cruise speed of 650 miles per hour (1,046 kilometers per hour). Major Joseph Rogers demonstrated the maximum speed of Mach 2.31 (1,525 miles per hour/2,454 kilometers per hour) at 40,000 feet (12,192 meters) during his record-breaking run. The F-106A had a service ceiling is 57,000 feet (17,374 meters) and a rate of climb of 29,000 feet per minute (150 meters per second). It had a combat radius of 575 miles (925 kilometers) and a maximum range of 1,809 miles (2,911 kilometers).

The Delta Dart was armed with four AIM-4 Falcon air-to-air guided missiles and one AIM-2A Genie unguided rocket with a 1.5 kiloton W25 nuclear warhead. In 1972, the General Electric M61 Vulcan 20mm cannon was added.

Convair built 342 F-106 interceptors. 277 were F-106As and the remainder were F-106B two-seat trainers.

F-106A 56-0467 was built in April 1958 and was the eighteenth production aircraft. After being used for flight testing at Edwards Air Force Base it was converted back to an operational interceptor and assigned to the 329th Tactical Fighter Squadron at nearby George Air Force Base.

On 14 August 1961, while taking off from George Air Force Base, Victorville, California, on a routine training mission, 56-0467’s right tire blew out. The pilot, James Wilkinson, flew until most of the airplane’s fuel had been exhausted, and then landed at Edwards Air Force Base because of its longer runway and available emergency equipment. After touching down, the right wheel and brake assembly caught fire. The flames quickly spread to the wing and fuselage. The aircraft slid to a stop and the pilot safely escaped. 467 was totally destroyed.

56-0459, which had been scheduled to make the speed record flights, is on display at the McChord Air Force Base Museum.

19 November 1952. Captain James Slade Nash, U.S. Air Force, a test pilot at the Air Force Flight Test Center, Edwards Air Force Base, California, flew a North American Aviation F-86D-20-NA Sabre, 51-2945, to a Fédération Aéronautique Internationale (FAI) World Absolute Speed Record at the Salton Sea, California. Operating out of NAS El Centro, Captain Nash flew four passes over a 3-kilometer course at an altitude of 125 feet (38 meters). The official average speed was 1,124.14 kilometers per hour (698.508 miles per hour).¹ He was awarded the FAI’s Henry de la Vaulx Medal for achieving the World Absolute Speed Record.

The record-setting F-86D, 51-2945, was damaged in a ground collision with a Douglas RB-26C Invader, 44-35942, 29 October 1953, at K-14, Kinpo, Korea.

The F-86D was an all-weather interceptor developed from North American Aviation F-86 Sabre day fighter. It was the first single-seat interceptor, and it used a very sophisticated—for its time—electronic fire control system. It was equipped with radar and armed with twenty-four unguided 2.75-inch (70 millimeter) Mk 4 Folding-Fin Aerial Rockets (FFAR) rockets carried in a retractable tray in its belly.

The F-86D was larger than the F-86A, E and F fighters, with a wider fuselage. The day fighter’s sliding canopy was replaced with a hinged “clamshell” canopy. Its length was increased to 40 feet, 3 inches (12.27 meters) with a wingspan of 37 feet, 1.5 inches (11.32 meters). The F-86D had an empty weight of 13,518 pounds (6,132 kilograms) and its gross weight was 19,975 pounds (9,061 kilograms).

The F-86D was equipped with a General Electric J47-GE-17 single-shaft axial-flow turbojet engine, producing 5,425 pounds of thrust (24.132 kilonewtons) at 7,950 r.p.m., or 7,500 pounds (33.362 kilonewtons) with afterburner. This engine was equipped with an electronic fuel control system which substantially reduced the pilot’s workload. The engine had a 12-stage compressor, 8 combustion chambers, and single-stage turbine. It was 226.0 inches (5.740 meters) long, 39.75 inches (1.010 meters) in diameters, and weighed 3,000 pounds (1,361 kilograms).

The F-86D had a range of 330 miles (531 kilometers) and a service ceiling of 49,750 feet (15,164 meters). Its rate of climb was 12,150 feet per minute (61.7 meters per second).

Between December 1949 and September 1954, 2,505 F-86D Sabres (sometimes called the “Sabre Dog”) were built by North American Aviation. There were many variants (“block numbers”) and by 1955, almost all the D-models had been returned to maintenance depots or the manufacturer for standardization. 981 of these aircraft were modified to a new F-86L standard. The last F-86D was removed from U.S. Air Force service in 1961.

23 October 1934: At Lago di Garda, Brescia, Italy, Warrant Officer Francesco Agello, Regia Aeronautica, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course when he flew the Macchi Aeronautica M.C. 72 float plane, serial number MM 181, to an average speed of 709.21 kilometers per hour (440.68 miles per hour).¹

A contemporary news article described the event:

FLYING the Machi-Castoldi 72 seaplane (3,000 h.p. special 24-cyl. Fiat) at Lake Garda on Tuesday of last week, Warrant-Officer Francesco Agello, of the Italian Royal Air Force, raised his own world’s air speed record by putting up a mean speed (subject to homologation) of 709.202 km./hr. (440.677 m.p.h.) for the usual four flights. His previous record stood at 682.403 km./hr. (423.76 m.p.h.)

The weather conditions under which the attempts were made were ideal, there being just sufficient breeze to take the glassiness off the water, so assisting the takeoff. Temperature was suitable, and the air was free from bumps.

Just before 3 p.m. Agello took off and made four runs over the three-kilometre course, clocking as follows:—

[Direction]         Secs.               km./hr.          m.p.h

North-South     15 29/100        705.882        438.614
South-North     15 19.2/100     710.433        441.423
North-South     15 18.1/100     711.462        442.081
South-North     15 23.4/100     709.034        440.738

After the successful attempt a banquet was held in the Officers’ Mess at Desenzano in Agello’s honour. The speeds were announced, and Col. Bernasconi, who is in command of the High-speed Flight, stated that Signor Mussolini had honoured Warrant-Officer Agello by promoting him to a full lieutenant.

Only a few modifications had been made to the Macchi-Castoldi since the previous attempt, chief among them being the substitution of wooden floats for the metal ones previously used.

As is well known. the most interesting feature of the machine is the extremely unconventional power-unit, the Fiat A.S.6. The problem of frontal area for such a powerful unit as was specified was solved by placing the twenty-four cylinders (totalling in capacity over fifty litres) in two rows, forming a 60 deg. “vee,” and further, arranging them in two mechanically independent groups.

Each group has its own crank shaft, but a single crank case is used for both. The crank shafts, which rotate in opposite directions, are coupled in the centre by spur-gear reduction units, which drive two airscrew shafts. One of these shafts is hollow, and the other operates within it. The two shafts run forward through the “vee” of the front unit, and each carries an airscrew; so that there are two of the latter, close together, but revolving in opposite directions.

Each engine unit has independent camshafts (two per engine), water pump and dual Marelli magnetos, but a common induction system is used, an eight-jet carburetter being mounted behind the rear unit and mixture being drawn from it passed to the cylinders by a supercharger geared up to 20,000 r.p.m. An interesting point is that this supercharger absorbs 200 h.p., and, since it is driven by the rear engine, the blades of the front airscrew (which the rear engine drives) are given different inclination to correct for the slight difference in power.

The power units develop 3,000 h.p. at 3,200 r.p.m., and weighs 2,045lb., giving a weight per h.p. of 0.706lb. The all-up weight of the machine, with pilot and full tanks, is 6,670lb.

British equipment figured in the success, for Castrol oil and K.L.G. plugs were used.

The Macchi-Castoldi M.C.72 was designed by Mario Castoldi for Aeronautica Macchi. It was a single-place, single-engine, low-wing monoplane float plane constructed of wood and metal. It was 8.32 meters (27 feet, 3.5 inches) long with a wingspan of 9.48 meters (31 feet, 1.25 inches) and height of 3.30 meters (10.83 feet). The M.C.72 had an empty weight of 2,505 kilograms (5,512 pounds), loaded weight of 2,907 kilograms (6,409 pounds) and maximum takeoff weight of 3,031 kilograms (6,669 pounds).

It was powered by a 50.256 liter (3,067 cubic inch) liquid-cooled, supercharged Fiat S.p.A. AS.6 24-cylinder 60° dual overhead cam (DOHC) V-24 engine with 4 valves per cylinder. The engine produced 3,100 horsepower at 3,300 r.p.m. and drove two counter-rotating metal two-bladed fixed pitch propellers with a diameter of 8 feet (2.56 meters). The counter-rotating blades cancelled the torque effect of the engine.

Surface radiators were placed on top of each wing and surface oil coolers on the floats.

Five Macchi M.C.72 float planes had been built for the 1931 Schneider Trophy race, but problems with the Fiat AS.6 engine, which was essentially two AS.5 V-12s assembled back-to-back, prevented them from competing.

Four test pilots, including Francesco Agello, had been selected to fly the airplanes for speed record attempts. Two were killed while testing the M.C.72, and the third died when another airplane crashed. The cause of the accidents were explosions within the engines’ intake tract. Though they ran perfectly on test stands, in flight, they began to backfire, then explode.

It was discovered by Rod Banks, a British engineer who had been called in to develop a special high-octane fuel, that the Fiat engineers had overlooked the ram effect of the 400 mile per hour slipstream. This caused the fuel mixture to become too lean, resulting in predetonation and backfiring. A modification was made to the intake and the problem was resolved.

Francesco Agello was twice awarded the Henry De La Vaulx Medal by the Fédération Aéronautique Internationale, and also awarded the Medaglia d’oro al valore aeronautico. In part, his citation read, “A high speed pilot of exceptional courage and, after competition in difficult and dangerous test flights during the development of the fastest seaplane in the world, twice he conquered the absolute world speed record.”

Captain Agello was killed in a mid-air collision, 26 November 1942, while testing a Macchi C.202 Fogore fighter.

16 September 1975: Alexander Vasilyevich Fedotov, Mikoyan Experimental Design Bureau’s chief test pilot, took the Product 83 prototype, E-155MP 83/1, for its first flight.

Project 83 was a two-seat, twin-engine, Mach 2.8+ interceptor, designed as a successor to the Mikoyan-Gurevich MiG 25 “Foxbat” and would be designated the MiG 31. The Soviet Ministry of Defense assigned odd numbered designators to fighter-type aircraft, while NATO, the North Atlantic Treaty Organization, gave them identifying names beginning with the letter F. NATO calls the MiG 31 “Foxhound.”

The E-155MP is 22.69 meters (77 feet, 5 inches) long with a wingspan of 13.46 meters (44 feet, 2 inches) and overall height of 5.15 meters (16 feet, 11 inches). Its empty weight is 20,800 kilograms (45,856 pounds), normal takeoff weight 40,600 kilograms (89,508 pounds) and maximum takeoff weight of 46,000 kilograms (101,413 pounds).

The aircraft is powered by two low-bypass-ratio Soloviev Design Bureau D-30 F6 turbofan engines, producing 91.00 kN (20,458 pounds of thrust), each, and 152.00 kN (34,171 pounds thrust), each, with afterburners.

The E-155MP had a maximum speed of Mach 2.82 (2,995 kilometers per hour/1,861 miles per hour) at 17,500 meters (57,415 feet) and 1500 (932 miles per hour) at low altitude. The prototype’s service ceiling was 20,000 meters (65,617 feet), and it had a range of 2,150 kilometers (1,336 miles).

The aircraft is unsuitable for air combat manuevering. The airframe is limited to a load factor of 5 Gs.

The production MiG 31 is armed with one Gryazev-Shipunov GSh-6 23 23mm six-barrel rotary cannon with 260 rounds of ammunition. Four Vympel R-33 long-range air-to-air missiles are carried in fuselage recesses, and various combinations of short and medium range missiles can be carried on pylons under the wings.

The MiG 31 was in production from 1979 until 1994. Beginning in 2010, a modernization program to bring the up to the MiG 31BM configuration. It is believed that approximately 400 MiG 31 interceptors are in service.

Alexander Vasilievich Fedotov born 23 June 1932 at Stalingrad, Russia (renamed Volgograd in 1961). He graduated from the Air Force Special School at Stalingrad,  and in 1950, entered the Soviet Army. Fedotov attended the Armavir Military Aviation School of Pilots at Amravir, Krasnodar Krai, Russia, graduating in 1952, and then became a flight instructor. In 1958 he attended the Ministry of Indutrial Aviation Test Pilot School at Zhukovsky. He was a test pilot for the Mikoyan Experimental Design Bureau from 1958 to 1984. In 1983, Alexander Fedotov was promoted to the rank of Major General in the Soviet Air Force.

On 22 July 1966, Fedotov was honored as a Hero of the Soviet Union. He was named an Honored Test Pilot of the Soviet Union, 21 February 1969. He was qualified as a Military Pilot 1st Class. Fedotov was twice awarded the Order of Lenin, and also held the Order of the Red Banner and the Order of the Red Banner of Labor.

During his career as a test pilot, Major General Fedotov had been forced to eject from an airplane three times. He had also set 15 Fédération Aéronautique Internationale world records for speed, altitude and time to altitude. One of these, FAI Record File Number 2825, in which he flew a Mikoyan E-266M to 37,650 meters (123,534 feet), 31 August 1977, remains the current record. The FAI has also honored him three times with The De la Vaulx Medal (1961, 1973 and 1977), and in 1976 awarded him the FAI’s Gold Air Medal.

Major General Alexander Vasilyevich Fedotov and his navigator, Valerie Sergeyvich Zaytevym, were killed when the second MiG 31 prototype, number 83/2, crashed during a test flight. Neither airman was able to eject.
