16 October 1963: Operation Greased Lightning. Major Sidney J. Kubesch, Major John Barrett and Captain Gerard Williamson flew from Tokyo, Japan, to London, England, non-stop, in 8 hours, 35 minutes, 20.4 seconds. Their airplane was a Convair B-58A-20-CF Hustler, serial number 61-2059, named Greased Lightning. It was assigned to the 305th Bombardment Wing, 19th Air Division, at Bunker Hill Air Force Base, Indiana.

Five inflight refuelings were required to complete the flight. The bomber had to slow from its supersonic cruise to rendezvous with the tankers. The B-58’s average speed was 692.71 miles per hour (1,114.81 kilometers per hour). The time from Tokyo to Anchorage, Alaska was 3 hours, 9 minutes, 42 seconds at an average speed of 1,093.4 miles per hour (1,759.7 kilometers per hour); and Anchorage to London, 5 hours, 24 minutes, 54 seconds at 826.9 miles per hour (1.330.8 kilometers per hour).

Greased Lightning‘s speed record still stands.

The B-58 Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator located in individual cockpits. The aircraft is a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.

The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and an overall height of 31 feet 5 inches (9.576 meters). The wing’s leading edge is swept back at a 60° angle and the fuselage incorporates the “area rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder, and there are no flaps.

The B-58A was powered by four General Electric J79-GE-5 axial-flow afterburning turbojet engines, suspended under the wings from pylons. This was a single-shaft engine with a 17-stage compressor and 3-stage turbine, rated at 10,300 pounds of thrust (45.82 kilonewtons), and 15,600 pounds (69.39 kilonewtons) with afterburner. The J79-GE-5 was 16 feet, 10.2 inches (5.136 meters) long and 3 feet, 2.0 inches (0.965 meters) in diameter.

The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).

The B-58 weapons load was a combination of a W-39 warhead, and/or Mk.43 or B61 nuclear bombs. The W-39 warhead, the same used with the Redstone IRBM or Snark cruise missile, was carried in a jettisonable centerline pod, which also carried fuel for the aircraft. The smaller bombs were carried on underwing hardpoints. For defense, there was a General Electric M61 Vulcan 20×102 mm six-barreled rotary cannon mounted in the tail, with 1,200 rounds of linked ammunition, controlled by the Defensive Systems Officer.

Convair B-58A-20 CF 61-2059 is in the collection of the Strategic Air and Space Museum, Ashland, Nebraska.

Fitzhugh L. Fulton, Jr., 1942.

Fitzhugh Lee Fulton, Jr., was born 6 June 1925 at Blakeley, Georgia. He was the son of Fitzhugh Lee Fulton and Manila T. Fulton. He graduated from Columbus High School, Columbus, Georgia, in 1942. He later studied at Auburn University, Auburn, Alabama, and the University of Oklahoma, Norman, Oklahoma (just south of Oklahoma City). he graduated from Golden Gate University, San Francisco, California.

Fitz Fulton married Miss Erma I. Beck at Tucson, Arizona, 16 December 1945.

He entered the U.S. Army Air Corps in 1943. He flew the Douglas C-54 Skymaster transport during the Berlin Airlift and Douglas B-26 Invaders during the Korean War. Fulton graduated from the Air Force Experimental Test Pilot School in 1952. He served as project test pilot for the Convair B-58 Hustler supersonic bomber. At Edwards AFB, he flew the B-52 “motherships” for the X-15 Program. He flew the North American XB-70A Valkyrie to more than Mach 3. When Fulton retired from the Air Force in 1966, he was a lieutenant colonel assigned as Chief of Bomber and Transport Test Operations.

Fitz Fulton continued as a test pilot for NASA, flying as project pilot for the YF-12A and YF-12C research program. He flew all the early test flights of the NASA/Boeing 747 Shuttle Carrier Aircraft and carried the space shuttle prototype, Enterprise. By the time he had retired from NASA, Fulton had flown more than 16,000 hours in 235 aircraft types.

Fitzhugh Lee Fulton, Jr., died at Thousand Oaks, California, 4 February 2015, at the age of 89 years.

22 June 1962

The last of 744 Boeing B-52 Stratofortress bombers, B-52H-175-BW, 61-0040, is rolled out at the Boeing plant at Wichita, Kansas. (Boeing)

22 June 1962: The last of 744 Boeing B-52 Stratofortress strategic bombers, B-52H-175-BW, serial number 61-0040, was rolled out at the Boeing Military Airplane Company plant in Wichita, Kansas.

The U.S. Air Force contracted 62 B-52H Stratofortresses, serial numbers 60-0001 through 60-0062, on 6 May 1960. A second group of 40, serials 61-0001 through 61-0040, were ordered later. All were built at the Boeing Wichita plant.

The B-52H, like the B-52G, is a re-engineered aircraft, structurally different from the XB-52, YB-52, and B-52A–B-52F Stratofortress variants. It is lighter, carries more internal fuel, giving it a longer unrefueled range, and is strengthened for low-altitude flight. The shorter vertical fin is intended to prevent the losses caused by the original tall fin in turbulent air. The B-52H is equipped with quieter, more efficient turbofan engines.

The B-52H was developed to carry four Douglas GAM-87 Skybolt air-launched ballistic missiles on pylons mounted under the wings, inboard of the engines. The Skybolt was armed with a 1-megaton W-59 thermonuclear warhead. The program was cancelled, however, and the North American Aviation AGM-28 Hound Dog air-launched cruise missile was used instead. (Interestingly, the Hound Dog’s Pratt & Whitney J52-P-3 turbojet engine could be used to supplement the B-52’s takeoff thrust, and then refueled from the bomber’s tanks before being air-launched.)

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It was originally operated by a crew of six: two pilots, a navigator and a radar navigator, an electronic warfare officer, and a gunner. (The gunner was eliminated after 1991). The airplane is 159 feet, 4 inches (48.565 meters) long, with a wing span of 185 feet (56.388 meters). It is 40 feet, 8 inches (12.395 meters) high to the top of the vertical fin. The B-52H uses the vertical fin developed for the B-52G, which is 22 feet, 11 inches (6.985 meters) tall. This is 7 feet, 8 inches (2.337 meters) shorter than the fin on the XB-52–B-52F aircraft, but the fin’s chord is longer.

The wings of the B-52H have a total area of 4,000 square feet ( square meters). The leading edges are swept aft to 36° 58′. The angle of incidence is 6°, and there is 2° 30′ dihedral. (The wings are very flexible and exhibit pronounced anhedral when on the ground.) To limit twisting in flight, the B-52 has spoilers on top of the wings rather than ailerons at the trailing edges.

The bomber has an empty weight of 172,740 pounds (78,354 kilograms) and its Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

The most significant difference between the B-52H and the earlier Stratofortresses is the replacement of the eight Pratt & Whitney J57-series turbojet engines with eight Pratt & Whitney Turbo Wasp JT3D-2 (TF33-P-3) turbofans, which are significantly more efficient. They are quieter and don’t emit the dark smoke trails of the turbojets. The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, a 14-stage compressor section (7-stage intermediate pressure, 7-stage high-pressure) and and a 4-stage turbine (1-stage high-pressure, 3-stage low-pressure). The TF33-P-3 has a maximum continuous power rating of 14,500 pounds of thrust (64.499 kilonewtons) at 9,750 r.p.m., N1. Military Power, limited to 30 minutes, is 16,500 pounds (73.396 kilonewtons) at 10,000 r.p.m., N1. Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons) at 10,050 r.p.m., N1, with a 5-minute limit. The TF33-P-3 is 11 feet, 4.32 inches (3.4625 meters) long, 4 feet, 4.93 inches (1.3442 meters) in diameter and weighs 3,900 pounds (1,769 kilograms).

The B-52H has a cruise speed of 456 knots (525 miles per hour/845 kilometers per hour). It has a maximum speed, with Military Power, of 555 knots (639 miles per hour/1,028 kilometers per hour) at 20,700 feet (6,309 meters)—0.906 Mach. The service ceiling is 46,900 feet (14,295 meters). The unrefueled range is 8,000 miles (12,875 kilometers). With inflight refueling, its range is limited only by the endurance of its crew.

The B-52H can carry a wide variety of conventional free-fall or guided bombs, land-attack or anti-ship cruise missiles, and thermonuclear bombs or cruise missiles. These can be carried both in the internal bomb bay or on underwing pylons. The bomb load is approximately 70,000 pounds (31,751 kilograms).

The B-52H was equipped with a General Electric M61 Vulcan 20 mm six-barreled rotary cannon (a “Gatling gun”) in a remotely-operated tail turret. The gun had a rate of fire of 4,000 rounds per minute, and had a magazine capacity of 1,242 rounds. After 1991, the gun and its radar system were removed from the bomber fleet. The flight crew was reduced to five.

The B-52H was armed with a 20 mm M61 Vulcan 6-barreled cannon in place of the four .50-caliber machine guns of the earlier variants.

102 B-52Hs were built by Boeing Wichita. Beginning in 2009, eighteen B-52H bombers were placed in climate-controlled long term storage at Tinker Air Force Base, Oklahoma.  In 2014, the entire fleet began a major avionics upgrade. As of December 2015, fifty-eight of the bombers remained in the active fleet of the United States Air Force and eighteen are assigned to the Air Force Reserve.

Recently, a B-52H-156-BW Stratofortress, 61-0007, Ghost Rider, was returned to operational status after eight years in storage at Davis-Monthan Air Force Base, Tucson, Arizona. 45,000 man-hours were required to restore the bomber.

The B-52H is expected to remain in service until 2040.

62 years after roll-out, 61-0040 is still in service with the United States Air Force, assigned to the 23rd Bomb Squadron, 5th Bomb Wing, at Minot Air Force Base, North Dakota.

The B-58A Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator, each located in individual cockpits. The aircraft had a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors. The fuselage incorporates the “Area Rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.

The “Hustler” was 96.8 feet (29.5 meters) long, with a wing span of 56.8 feet (17.3 meters) and an overall height of 31.4 feet (9.6 meters). The wings’ leading edges were swept back at a 60° angle. The wings had a 3°0′ angle of incidence, 2°14′ dihedral, and a total area of 1,542.5 square feet (143.3 square meters).

The B-58A had an empty weight of 51,061 pounds (23,161 kilograms). Its Maximum Takeoff Weight (MTOW) was 90,000 pounds (40,823 kilograms), but once airborne, it could take on additional fuel from a tanker, raising the bomber’s maximum weight to 125,147 pounds (56,766 kilograms).

The B-58A was powered by four General Electric J79-GE-5 afterburning turbojet engines, suspended under the wings from pylons. These were single-shaft axial-flow engines with a 17-stage compressor and 3-stage turbine. The J79-GE-5 had a continuous power rating of 9,700 pounds of thrust (43.15 kilonewtons), Military Power, 10,000 pounds of thrust (44.49 kilonewtons), and Maximum Power, 15,600 pounds (69.39 kilonewtons) with afterburner. (All ratings at 7,460 r.p.m.) The engine was 16 feet, 10.2 inches (5.131 meters) long and 3 feet, 2.0 inches (0.889 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).

The bomber had a cruise speed of 626 miles per hour (1,007 kilometers per hour) from 30,000 to 50,000 feet (9,144–15,240 meters), and a maximum speed of 1,319 miles per hour (2,124 kilometers per hour) at 56,100 feet (17,099 meters). The B-58’s service ceiling was 67,200 feet (20,483 meters).

Jet fuel (JP-4) was carried in three tanks inside the airplane’s fuselage, and two tanks in a streamlined drop tank. The total capacity of the five tanks was 15,369 gallons (58,178 liters). Its combat radius was 2,589 miles (4,167 kilometers) and the maximum ferry range was 6,483 miles (10,434 kilometers).

The B-58 weapons load was a combination of W-39, B43 or B61 nuclear bombs. The W-39 was carried in the centerline pod. (A two-component mission pod was also available.) The W-39 was the same warhead used on the PGM-11 Redstone intermediate range ballistic missile and the SM-62 Snark intercontinental cruise missile. It was a two-stage radiation-implosion thermonuclear warhead with an explosive yield of 3.8 megatons. The warhead weighed 6,230 pounds (2,826 kilograms). The B-43 and B-61 bombs were carried on four hardpoints under the fuselage.

There was a defensive General Electric M61 Vulcan 20 mm rotary cannon mounted in the bomber’s tail, with a maximum 1,040 rounds of ammunition. The gun was remotely-controlled by the Defensive Systems Officer.

17 April 1956: Lockheed Aircraft Corporation rolled out the very first production F-104A Starfighter, 55-2956, at Air Force Plant 42, Palmdale, California. This airplane, one of the original seventeen pre-production YF-104As, incorporated many improvements over the XF-104 prototype, the most visible being a longer fuselage.

Once the configuration was finalized, 55-2956 was the first YF-104A converted to the F-104A production standard. In this photograph, the F-104’s secret engine intakes are covered by false fairings.

The Lockheed F-104A Starfighter was a single-place, single-engine supersonic interceptor. It was designed by a team lead by the legendary Clarence L. “Kelly” Johnson. The F-104A was 54 feet, 8 inches (16.662 meters) long with a wingspan of 21 feet, 9 inches (6.629 meters) and overall height of 13 feet, 5 inches (4.089 meters). It had an empty weight of 13,184 pounds (5,980.2 kilograms), combat weight of 17,988 pounds (8,159.2 kilograms), gross weight of 22,614 pounds (10,257.5 kilograms) and a maximum takeoff weight of 25,840 pounds (11,720.8 kilograms). Internal fuel capacity was 897 gallons (3,395.5 liters).

The F-104A was powered by a single General Electric J79-GE-3A engine, a single-spool axial-flow afterburning turbojet, which used a 17-stage compressor and 3-stage turbine. The J79-GE-3A is rated at 9,600 pounds of thrust (42.70 kilonewtons), and 15,000 pounds (66.72 kilonewtons) with afterburner. The engine is 17 feet, 3.5 inches (5.271 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighs 3,325 pounds (1,508 kilograms).

The F-104A had a maximum speed of 1,037 miles per hour (1,669 kilometers per hour) at 50,000 feet (15,240 meters). Its stall speed was 198 miles per hour (319 kilometers per hour). The Starfighter’s initial rate of climb was 60,395 feet per minute (306.8 meters per second) and its service ceiling was 64,795 feet (19,750 meters).

Armament was one General Electric M61 Vulcan six-barreled revolving cannon with 725 rounds of 20 mm ammunition. An AIM-9B Sidewinder heat-seeking air-to-air missile could be carried on each wing tip, or a jettisonable fuel tank with a capacity of 141.5 gallons (535.6 liters).

Lockheed built 153 of the F-104A Starfighter initial production version. A total of 2,578 F-104s of all variants were produced by Lockheed and its licensees, Canadair, Fiat, Fokker, MBB, Messerschmitt,  Mitsubishi and SABCA. By 1969, the F-104A had been retired from service. The last Starfighter, an Aeritalia-built F-104S ASA/M of the  Aeronautica Militare Italiana, was retired in October 2004.

This Starfighter, 55-2956, was converted to a JF-104A with specialized instrumentation. It was transferred to the U.S. Navy to test AIM-9 Sidewinder missiles at Naval Ordnance Test Station (NOTS) China Lake, approximately 55 miles (88 kilometers) north-northeast of Edwards Air Force Base in the high desert of Southern California. 55-2956 was damaged beyond repair when it lost power on takeoff and ran off the runway at Armitage Field, 15 June 1959.
