The first production Mikoyan-Gurevich MiG-15 (SV), No. 101003. (Mikoyan Design Bureau)
31 December 1948: One year and one day after the first flight of the MiG I-310 S01 prototype, the first production Mikoyan-Gurevich MiG-15, serial number 101003, made its first flight. The production aircraft were based on the third I-310 prototype, S03. No. 101003 was designated МиГ-15(CB) (MiG-15 SV), and was retained by Mikoyan OKB for testing.
The MiG-15 is a single-seat, single-engine turbojet-powered fighter interceptor, designed to attack heavy bombers. Designed for high-subsonic speed, the wings were swept aft to 35° at 25% chord and had 2° anhedral. The wings were very thin to minimize aerodynamic drag and used “fences” to control air flow. The horizontal stabilizer was swept 40°, and the vertical fin, 55.7°.
Rolls-Royce Nene Mk.I and Mk.II turbojet engines had been used in the three I-310 prototypes. The British engine was reverse-engineered by Vladimir Yakovlevich Klimov and manufactured at Factory No. 45 in Moscow as the RD-45F. The engine produced a maximum 22.26 kilonewtons of thrust (5,004 pounds of thrust). It was improved and designated VK-1. Most MiG-15s used this engine.
The production fighter was 10.10 meters (33 feet, 2 inches) long, with a wingspan of 10.08 meters (33 feet, 1 inch) and height of 3.17 meters (10 feet, 5 inches). The total wing area was 20.60 square meters (222 square feet). The interceptor’s empty weight was 3,247 kilograms (7,158 pounds), and its takeoff weight was 4,917 kilograms (10,840 pounds).
The MiG-15 had a cruise speed 974 kilometers per hour (605 miles per hour, 0.79 Mach). Its maximum speed was 1,047 kilometers per hour (565 knots, or 651 miles per hour)—0.99 Mach—at low altitude, and 1,031 kilometers per hour (557 knots, 641 miles per hour, 0.97 Mach) at 5,000 meters (16,404 feet). The maximum rate of climb was 2,520 meters per minute (8,268 feet per minute), and its service ceiling was 15,100 meters (49,541 feet). The fighter had a practical range of 1,335 kilometers (830 miles).
Armament consisted of one Nudelman NS-37 37 mm cannon with 40 rounds of ammunition, and two Nudelman-Rikhter NR-23 23 mm cannon with 80 rounds per gun.
The first MiG 15, 101003, was built at Factory No. 1. Full scale production was considered so important that four other aircraft types were discontinued so that their factories could be used to build MiG-15s. They were also license-built in Poland and Czechoslovakia. More than 18,000 MiG-15s have been built. It has served in the air forces of at least 44 countries.
The MiG-15 soon entered combat in the Korean War. It scored its first air-to-air victory, 1 November 1950, when First Lieutenant Fiodor V. Chizh shot down a U.S. Air Force F-51 Mustang.

27 December 1951: The North American Aviation XFJ-2B Fury, Bu. No. 133756, made its first flight at Los Angeles International Airport with test pilot Robert Anderson Hoover at the controls.
The XFJ-2B was a prototype aircraft carrier-based fighter for the United States Navy and Marine Corps. It was modified from a standard production U.S. Air Force F-86E-10-NA Sabre day fighter. The primary difference was the substitution of four 20 mm Colt Mark 12 autocannon for the six .50-caliber Browning M-3 machine guns of the F-86E. 150 rounds per gun were carried. The aircraft was flown to the Naval Ordnance Test Station, Armitage Field, China Lake, California, for armament testing.
The second and third prototypes were unarmed but fitted with an arrestor hook, catapult points, folding wings and a lengthened nose gear strut to increase the fighter’s static angle of attack for takeoff and landings. These two prototypes were used for aircraft carrier trials.
Production FJ-2 Fury fighters were built at North American’s Columbus, Ohio plant, along with F-86F Sabres for the Air Force.

Robert A. Hoover was one of the world’s best known exhibition pilots. He was a fighter pilot in the U.S. Army Air Corps during World War II. While flying a British Supermarine Spitfire with the 52nd Fighter Group based at Sicily, he was shot down, captured, and held as a prisoner of war at Stalag Luft I in Germany.
After 16 months in captivity, Hoover escaped, stole a Luftwaffe Focke-Wulf Fw 190 and flew it to The Netherlands.
After the war, Bob Hoover trained as a test pilot at Wright Field, Ohio, and remained in the Air Force until 1948. He worked as a test pilot for the Allison Division of General Motors, and then went on to North American Aviation.
Bob Hoover was famous for flying aerobatic demonstrations around the world in his yellow P-51D Mustang and a twin-engine Shrike Commander, both built by North American Aviation.
Robert Anderson Hoover died 25 October 2016 at the age of 94 years.

26 December 1948: Test pilot Ivan Evgrafovich Federov (Ива́н Евгра́фович Фёдоров ) became the first pilot in the Soviet Union to exceed Mach 1 when he flew the Lavochkin La-176 in a dive from 9,050 meters (29,692 feet) to 6,000 meters (19,685 feet).
It was first thought that the La-176’s airspeed indicator had malfunctioned, but during subsequent testing conducted the first week of January 1949, Federov repeated the dive and six times reached Mach 1.02.
The La-176 was destroyed when its canopy failed during supersonic flight. Test pilot I.V. Sokolovsky was killed.
Lavochkin La-176
The La-176 was a single-seat, single-engine fighter, derived from the earlier La-168. The leading edge of its wings and tail surfaces were swept at 45°. The fighter was 36 feet (10.973 meters) long with a wingspan of 28 feet, 2 inches (8.585 meters). It had an empty weight of 3,111 kilograms (6,858.6 pounds) and loaded weight of 4,631 kilograms (10,210 pounds).
The La-176 was powered by a Klimov VK-1 centrifugal-flow turbojet, developed from the Rolls-Royce Nene. The British engines were reverse-engineered by Vladimir Yakovlevich Klimov and manufactured at Factory No. 45 in Moscow as the Klimov VK-1. The VK-1 used a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. It produced a maximum 26.5 kilonewtons of thrust (5,957 pounds of thrust). The VK-1 was 2.600 meters (8 feet, 6.4 inches) long, 1.300 meters (4 feet, 3.2 inches) in diameter, and weighed 872 kilograms (1,922 pounds).
The swept-wing jet had a maximum speed of 648 miles per hour (1,042.85 kilometers per hour) and a range of 621 miles (999.4 kilometers).
Armament consisted of one Nudelman N-37 30 mm cannon and two Nudelman-Suranov NS-23 23 mm cannon.

Colonel Ivan Evgrafovich Federov (23 February 1914–12 February 2011) was a Soviet Air Force fighter pilot who fought in the Spanish civil war (where he was known as Diablo Rojo, the Red Devil), the Russo-Finish War, World War II, China and Korea. He may have shot down as many as 135 enemy airplanes. He was personally awarded the Iron Cross by Adolf Hitler, Chancellor of Germany, in 1941. His Soviet Awards include Hero of the Soviet Union, the Order of Lenin, Order of Alexander Nevsky, Order of the Red Banner, Order of the Patriotic War 1st Degree, Order of the Patriotic War 2nd Degree, and Order of the Red Star.

21 December 1916: Harry George Hawker, M.B.E., A.F.C., made the first flight of the Sopwith Camel at Brooklands Aerodrome, Surrey, England. This airplane would become the Royal Air Force’s most successful fighter of World War I.
The Sopwith Camel F.1 was a British single-place, single-engine biplane fighter, produced by the Sopwith Aviation Co., Ltd., Canbury Park Road, Kingston-on-Thames. The airplane was constructed of a wooden framework, with the forward fuselage being covered with aluminum panels and plywood, while the aft fuselage, wings and tail surfaces were covered with fabric.
The length of the Camel F.1 varied from 18 feet, 6 inches (5.639 meters) to 19 feet, 0 inches (5.791 meters), depending on which engine was installed. Both upper and lower wings had a span of 28 feet, 0 inches (8.534 meters) and chord of 4 feet, 6 inches (1.372 meters). They were separated vertically by 5 feet (1.524 meters) at the fuselage. The upper wing had 0° dihedral, while the lower wing had 5° dihedral and was staggered 1 foot, 6 inches (0.457 meters) behind the upper wing. The single-bay wings were braced with airfoil-shaped streamline wires. The overall height of the Camel also varied with the engine, from 8 feet, 6 inches (2.591 meters) to 8 feet, 9 inches (2.667 meters).
The heaviest Camel F.1 variant used the Le Rhône 180 h.p. engine. It had an empty weight of 1,048 pounds (475 kilograms). Its gross weight of 1,567 pounds (711 kilograms). The lightest was equipped with the Gnôme Monosoupape 100 horsepower engine, with weights of 882 pounds (400 kilograms) and 1,387 pounds (629 kilograms), respectively.

The first Camel was powered by an air-cooled 15.268 liter (931.72 cubic inches) Société Clerget-Blin et Cie Clerget Type 9 nine-cylinder rotary engine which produced 110 horsepower at 1,200 r.p.m. and drove a wooden two-bladed propeller. Eight different rotary engines ¹ from four manufacturers, ranging from 100 to 180 horsepower, were used in the type.
The best performance came with the Bentley B.R.1 engine (5.7:1 compression ratio). This variant had a maximum speed of 121 miles per hour (195 kilometers per hour) at 10,000 feet (3,048 meters), and 114.5 miles per hour (184 kilometers per hour) at 15,000 feet (4,572 meters). It could climb to 6,500 feet (1,981 meters) in 4 minutes, 35 seconds; to 10,000 feet (3,048 meters) in 8 minutes, 10 seconds; and 15,000 feet (4,572 meters) in 15 minutes, 55 seconds. It had a service ceiling of 22,000 feet (6,706 meters). Two other Camel variants could reach 24,000 feet (7,315 meters).
The Bentley B.R.1 rotary engine was designed by Lieutenant Walter Owen Bentley, Royal Naval Air Service (later, Captain, Royal Air Force), based on the Clerget Type 9, but with major improvements. It used aluminum cylinders shrunk on to steel liners, with aluminum pistons. The Bentley B.R.1 (originally named the Admiralty Rotary, A.R.1, as it was intended for use by the Royal Navy) was an air-cooled, normally-aspirated 17.304 liter (1,055.948 cubic inches) right-hand tractor, nine-cylinder rotary engine with a compression ratio of 5.7:1. It was rated at 150 horsepower at 1,250 r.p.m. The B.R.1 was 1.110 meters (3 feet, 7.7 inches) long, 1.070 meters (3 feet, 6.125 inches) in diameter and weighed 184 kilograms (406 pounds.) The engine was manufactured by Humber, Ltd., Coventry, England, and Vickers, Ltd., Crayford.

The Camel was armed with two fixed, forward-firing .303-caliber (7.7×56mmR) Vickers machine guns, synchronized to fire forward through the propeller. These guns were modified for air cooling. Some night fighter variants substituted Lewis machine guns mounted above the upper wing for the Vickers guns. Four 25 pound (11.3 kilogram) bombs could be carried on racks under the fuselage.
The Sopwith Camel was a difficult airplane to fly. Most of its weight was concentrated far forward, making it unstable, but, at the same time making the fighter highly maneuverable. The rotary engine, with so much of its mass in rotation, caused a torque effect that rolled the airplane to the right to a much greater degree than in airplanes equipped with radial or V-type engines. A skilled pilot could use this to his advantage, but many Camels ended upside down while taking off.

Twelve manufacturers ² produced 5,490 Sopwith Camels between 1916 and 1920. By the end of World War I, it was becoming outclassed by newer aircraft, however it was the single most successful fighter of the war, shooting down 1,294 enemy aircraft.
One single fighter, Major William Barker’s Sopwith Aviation Co., Ltd., Camel F.1 B.6313 shot down 46 enemy aircraft, more than any other fighter in history.
It is believed that only seven Sopwith Camels still exist.
