3 June 1946: Lieutenant Henry A. Johnson, U.S. Army Air Force, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 1,000 Kilometers Without Payload flying a Lockheed P-80A-1-LO Shooting Star, serial number 44-85123, at Dayton, Ohio. The average speed was 745.08 kilometers per hour (462.97 miles per hour). The elapsed time was 1 hour, 20 minutes, 31 seconds.¹
This airplane had earlier set a transcontinental speed record when Colonel William H. Councill flew it from Daugherty Field, Long Beach, California to La Guardia Field, New York, in 4 hours, 13 minutes, 26 seconds on 26 January 1946. It would go on to win the Thompson Trophy Race J Division, 2 September 1946, when Major Gustav E. Lundquist flew it to an average speed of 515.853 miles per hour (830.185 kilometers per hour) over the 180-kilometer course.

The Lockheed P-80-1-LO was the United States’ first operational jet fighter. It was a single-seat, single engine airplane, designed by a team of engineers led by Clarence L. (“Kelly”) Johnson. The prototype XP-80A, 44-83020, nicknamed Lulu-Belle, was first flown by test pilot Tony LeVier at Muroc Army Air Field (now known as Edwards AFB) 8 January 1944.
The P-80A was 34 feet, 6 inches (10.516 meters) long with a wingspan of 38 feet, 10.5 inches (37 feet, 7.5 inches with “clipped” wing tips) (11.849 or 11.468 meters) and an overall height of 11 feet, 4 inches (3.454 meters). The wings had 1° incidence with -1° 30° twist, and 3° 50′ dihedral. The leading edges were swept aft 9° 18′ 33″. The total wing area was 237.70 square feet (22.08 square meters). The P-80A weighed 7,920 pounds empty (3,593 kilograms) and had a maximum takeoff weight of 14,000 pounds (6,350 kilograms).

Early production P-80As were powered by either an Allison J33-A-9 or a General Electric J33-GE-11 turbojet engine. The J33 was a licensed version of the Rolls-Royce Derwent. It was a single-shaft turbojet with a 1-stage centrifugal compressor section and a 1-stage axial-flow turbine. The -9 and -11 engines were rated at 3,825 pounds of thrust (17.014 kilonewtons) at 11,500 r.p.m. They were 8 feet, 6.9 inches (2.614 meters) long, 4 feet, 2.5 inches (1.283 meters) in diameter and weighed 1,775 pounds (805 kilograms).
The P-80A-1 had a maximum speed of 510 miles per hour (821 kilometers per hour) at Sea Level, 520 miles per hour (837 kilometers per hour) at 20,000 feet (6,096 meters), and 495 miles per hour (797 kilometers per hour) at 40,000 feet (12,192 meters). The service ceiling was 45,000 feet (13,716 meters).
Several hundred of the early production P-80 Shooting stars had all of their surface seams filled, and the airplanes were primed and painted. Although this process added 60 pounds (27 kilograms) to the empty weight, the decrease in drag allowed a 10 mile per hour (16 kilometers per hour) increase in top speed. The painted surface was difficult to maintain in the field and the process was discontinued.
The P-80A Shooting Star was armed with six Browning AN-M3 .50-caliber aircraft machine guns mounted in the nose, with 300 rounds of ammunition per gun.

North American Aviation P-86A-1-NA Sabre 47-605, the first production aircraft. (U.S. Air Force)
20 May 1948: The first production North American Aviation, Inc., P-86A-1-NA, 47-605, made its first flight.
The P-86A-1-NA was very similar to the three XP-86 prototypes. As an operational fighter, its empty weight increased 347 pounds to 10,077 pounds. The Chevrolet J35-C-3 and Allison J35-A-5 engines were replaced with a more powerful General Electric J47-GE-1. The fighter’s maximum speed increased 74 miles per hour to 673 miles per hour at Sea Level.
The P-86 was unlike any airplane before it. (The designation was changed to F-86 the following month.) It was the first airplane produced with a swept wing. After analyzing World War II test data for the Messerschmitt Me 262, North American’s engineers designed a wing with a 35° degree sweepback to its leading edge. The wing sweep allowed high speed shock waves to form without stalling the entire wing. The wing tapered toward the tips, and its thickness also decreased from the root to the tip. In order to create a very strong but very thin wing, it was built with a two-layered aluminum skin, instead of ribs and spars, with each layer separated by “hat” sections. The thickness of the skin panels also tapered to decrease weight.

The wing incorporated leading edge “slats” which were airfoil sections that automatically extended below 290 knots, smoothing the air flow over the wing’s upper surface and creating more lift at slow speeds. Above that speed, aerodynamic forces closed the slats, decreasing drag and allowing for higher speeds. Effectively, the wing could change its shape in flight.
Like the XP-86, the P-86A was 37 feet, 6.5 inches (11.443 meters) long with a wingspan of 37 feet, 1.4 inches (11.313 meters) and overall height of 14 feet, 8.9 inches (4.493 meters). The empty weight was 10,077 pounds (4,571 kilograms), gross weight, 14,050 pounds (6,373 kilograms) and maximum takeoff weight was 15,876 pounds (7,201 kilograms).
The J47-GE-1 was an axial-flow turbojet with a 12-stage compressor, 8 combustion chambers, and single stage turbine. It had a normal power rating of 4,320 pounds of thrust (19.216 kilonewtons) at 7,370 r.p.m.; and military power, 5,200 pounds (23.131 kilonewtons) at 7,950 r.p.m. (30-minute limit).
The P-86A had an initial rate of climb 7,470 feet per minute (37.95 meters per second) and could reach 40,000 feet (12,192 meters) in 10 minutes, 24 seconds. Its service ceiling was 48,000 feet (14,630 meters).

The Sabre was armed with six Browning AN-M3 .50-caliber aircraft machine guns placed in the nose, with three on either side of the engine intake. These were lighter and had a higher rate of fire than the World War II AN-M2 machine guns. Ammunition containers had a capacity of 300 rounds, but normally they carried 267 rounds per gun. Early aircraft had small doors covering each gun port. They opened in 0.05 seconds but were difficult to keep properly adjusted, so they were soon deleted.
The airplane could also be armed with two bombs and up to sixteen 5-inch (12.7 centimeter) High Velocity Aerial Rockets (HVAR) on underwing hardpoints.
North American Aviation built thirty-three P-86A-1-NAs. The U.S. Air Force ordered 190 F-86Bs, but these were cancelled in favor of the F-86A-5-NA.
The F-86A became operational with the 1st Fighter Group at March Air Force Base, near Riverside, California. In February 1949, a contest was held within the group to select a name for the new fighter. “Sabre” was chosen.
47-605 was the first production P-86A-1-NA Sabre. (U.S. Air Force)

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.
Probably the best-known Lockheed F-94 variant is the all-rocket-armed F-94C Starfire. (Lockheed Martin)

17 March 1947: The prototype of the United States’ first jet-powered bomber, the North American Aviation XB-45 Tornado, 45-59479, made a one-hour first flight at Muroc Army Air Field in the high desert of southern California (later known as Edwards Air Force Base), with company test pilot George William Krebs and flight engineer Paul W. Brewer.
The Valley Times reported:
Secret Jet Bomber in First Hop
MUROC ARMY AIR FIELD, Calif., March 18—(AP)—America’s first bombing plane with four jet-propulsion engines—the B-45 which has been in secret production for many months—made an initial flight at this field yesterday.
The sleek North American Aviation, Inc., plane, with a wing-spread of 89½ feet and a length of 141 feet, [sic] has lines resembling a fighter more than a bomber and was described by the Army Air Forces as having an “exceedingly high” speed.
George Krebs, North American test pilot, flew the plane for its test, accompanied by Flight Engineer Paul W. Brewer.
The B-45 is considerably smaller than the famed B-29 but company officials said it is a heavy bomber by World War II standards. The company said its range approximates that of earlier heavy bombers while carrying a “substantially” heavier load.
The four General Electric J-35 jet engines are housed in pairs in single nacelles on each wing.
North American Aviation received a $73,900,000 contract to build 96 B-45s for the United States Army Air Forces within the next two years. They would be built by NAA in a leased portion of the Douglas Aircraft Company plant at Long Beach, California.
The photographs below show the XB-45 parked on Muroc Dry Lake. Notice that the windows over the bombardier’s compartment in the nose are painted on.
The North American Aviation XB-45 Tornado was a prototype four-engine bomber. It had a high-mounted straight wing and tricycle landing gear. It was 74 feet, 0 inches (22.555 meters) long with a wingspan of 89 feet, 6 inches (27.279 meters) and overall height of 25 feet, 2 inches (7.671 meters). It had an empty weight of 41,876 pounds (18,995 kilograms) and maximum takeoff weight of 82,600 pounds (37,467 kilograms).

The three prototypes were powered by four Allison-built General Electric J35-A-4 turbojet engines, installed in nacelles which were flush with the bottom of the wings. The J35 was a single-shaft engine with an 11-stage axial-flow compressor section and a single-stage turbine. The J35-A-4 was rated at 4,000 pounds of thrust (14.79 kilonewtons). The engine’s maximum speed was 8,000 r.p.m. The J35 was 14 feet, 0 inches (4.267 meters) long, 3 feet, 4.0 inches (1.016 meters) in diameter, and weighed 2,400 pounds (1,089 kilograms).
The maximum speed of the XB-45 was 494 miles per hour (795 kilometers per hour) at Sea Level and 516 miles per hour (830 kilometers per hour) at 14,000 feet (4,267 meters). The service ceiling was 37,600 feet (11,461 meters).

(U.S. Air Force 061020-F-1234S-017)
The production B-45A Tornado, made its first flight 24 February 1948, when George Krebs and Nick Pickard flew it from the NAA plant at Long Beach Airport to Muroc Army Air Field. The duration of the flight was 1 hour, 4 minutes. It was heavier that the XB-45 and had better performance. It was operated by two pilots, a bombardier/navigator and a tail gunner. It was 75 feet, 4 inches (22.962 meters) long with a wingspan of 89 feet, 0 inches (27.127 meters) and overall height of 25 feet, 2 inches (7.671 meters).
The B-45A had a total wing area of 1,175 square feet (109.2 square meters). The leading edges were swept aft 3° 30′. Their angle of incidence was 3° with -3° 30′ twist and 1° dihedral.
The bomber’s empty weight was 45,694 pounds (20,726 kilograms) and maximum takeoff weight was 91,775 pounds (41,628 kilograms).

The B-45A was powered by four General Electric J47-GE-13 turbojet engines. The J47 was an axial-flow turbojet with a 12-stage compressor and single stage turbine. It had a normal power rating of 4,320 pounds of thrust (19.216 kilonewtons) at 7,370 r.p.m.; military power, 5,200 pounds (23.131 kilonewtons) at 7,950 r.p.m. (30-minute limit); and maximum power rating of 6,000 pounds(26.689 kilonewtons) at 7,950 r.p.m., with water/alcohol injection (5-minute limit). The engine was 12 feet, 0.0 inches (3.658 meters) long, 3 feet, 3.0 inches (0.991 meters) in diameter and weighed 2,525 pounds (1,145 kilograms).
The B-45A Tornado had a cruise speed of 393 knots (452 miles per hour/728 kilometers per hour), and maximum speed of 492 knots (566 miles per hour (911 kilometers per hour) at 4,000 feet (1,219 meters). Its service ceiling was 46,800 feet (14,265 meters) and it had a maximum range of 1,886 nautical miles (2,170 statute miles/3,493 kilometers). An auxiliary 1,200 gallon (4,543 liters) fuel tank could be installed in the bomb bay.

The bomb load was 22,000 pounds (9,979 kilograms). It was capable of carrying the M110 (T-14), the U.S. version of the RAF’s “Grand Slam” bomb.) Two Browning .50-caliber AN-M3 machine guns were mounted in the tail for defense, with 600 rounds of ammunition per gun.
41 B-45As were modified to the “Back Breaker” configuration, which enabled them to be armed with nuclear weapons.
The B-45 served with both the United States Air Force and the Royal Air Force (RB-45C reconnaissance variant). 143 were built, including the three XB-45 prototypes. They served with the United States Air Force until 1959.

On 20 September 1948, near Alpaugh, California, the first production B-45A-1-NA Tornado, 47-001, was put into a dive to test the airplane’s design load factor. During the dive, one of the engines exploded, which tore off several cowling panels. These hit the horizontal stabilizer, damaging it. The B-45 pitched up, and both wings failed due to the g load. The prototype had no ejection seats and test pilots George Krebs and Nicholas Gibbs Pickard, unable to escape, were both killed.

TSGT Samuel O. Turner, U.S. Air Force, rests his hand on one of four air-cooled Browning AN-M3 .50-caliber aircraft machine guns of a B-52 tail turret. (“Bulldog Bulletin, Fall 1985”)
18 December 1972: On the first night of Operation Linebacker II, Staff Sergeant Samuel Olin Turner, United States Air Force, the gunner aboard Boeing B-52D-35-BW Stratofortress 56-676 (call sign “Brown 3”), saw a supersonic Mikoyan-Gurevich MiG 21 interceptor approaching the bomber from below and behind, with a second interceptor following at a distance.
As the Mach 2 fighter made a firing pass, Turner directed the four Browning AN-M3 .50-caliber machine guns of the bomber’s tail turret at the enemy fighter and opened fire. In a single 6–8 second burst, he expended 694 rounds of ammunition. He saw “a gigantic explosion to the rear of the aircraft.”
Master Sergeant Louis E. LeBlanc, the gunner on another B-52, “Brown 2,” had also seen the MiG 21 and confirmed Turner’s kill.

Staff Sergeant Turner was the first B-52 gunner to be officially credited with shooting down an enemy fighter, and the first aerial gunner to shoot down an enemy aircraft since the Korean War. He was awarded the Silver Star.
The citation reads,
Silver Star
Staff Sergent Samuel O. Turner distinguished himself by gallantry in connections with military operations against an opposing armed force as a B-52 Fire Control Operator near Hanoi, North Vietnam, on 18 December 1972. On this mission, Sergeant Turner’s aircraft was attacked by numerous enemy fighters. During these attacks he skillfully operated his gunnery radar equipment to train his guns on the attackers and destroyed one of them. By his courage in the face of hazardous combat conditions and outstanding professional skill, he successfully defended his aircraft and its crew and enabled it to complete its mission and return safely to base. By his gallantry and devotion to duty, Sergeant Turner has reflected great credit upon himself and to the United States Air Force.
