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 speed from Tokyo to Anchorage, Alaska was 3 hours, 9 minutes, 42 seconds at an average 1,093.4 miles per hour (1,759.7 kilometers per hour); and speed from 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.

26 October 1962: The United States Air Force received the 116th and last Convair B-58 Hustler, B-58A-20-CF 61-2080. It was assigned to the 305th Bombardment Wing at Bunker Hill Air Force Base, Indiana. After just over seven years in service, this airplane was retired to The Boneyard at Davis-Monthan Air Force Base, Tucson, Arizona, 6 January 1970. It is on display at the Pima Air & Space Museum, nearby.

The B-58 weapons load was a combination of Mark 39, B43 or B61 thermonuclear bombs. The weapons could be carried in a jettisonable centerline pod, which also carried fuel. The four of the smaller bombs could be carried on underwing hardpoints. There was a General Electric M61 20 mm rotary cannon mounted in the tail, with 1,200 rounds of ammunition, and controlled by the Defensive Systems Officer.
