On 10 May 1961, a U.S. Air Force/Convair B-58A-10-CF Hustler, serial number 59-2451, The Firefly, did just that. Flown by a crew consisting of Aircraft Commander, Major Elmer E. Murphy, Navigator, Major Eugene Moses, and Defensive Systems Officer, First Lieutenant David F. Dickerson, the Mach 2+ Strategic Air Command bomber flew 669.4 miles (1,077.3 kilometers) in 30 minutes, 43 seconds. Their average speed was 1,302.07 miles per hour (2,095 kilometers per hour).

The Convair 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 has a delta-winged configuration similar to Convair’s 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 overall height of 31 feet 5 inches (9.576 meters). The wings’ 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. There are no flaps.
The B-58’s delta wing has a total area of 1,542.5 square feet (143.3 square meters) and the leading edges are swept back at a 60° angle. The wing has an angle of incidence of 3° and 2° 14′ dihedral (outboard of Sta. 56.5).
The B-58A had an empty weight of 51,061 pounds (23161 kilograms), or 53,581 pounds (24,304 kilograms) with the MB-1 pod. The maximum takeoff weight was 158,000 pounds (71,668 kilograms).
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. It had a Normal Power rating of 9,700 pounds of thrust (43.148 kilonewtons). The Military Power rating was 10,000 pounds (44.482 kilonewtons), and it produced a maximum 15,600 pounds (69.392 kilonewtons) at 7,460 r.p.m., with afterburner. The J79-GE-5 was 16 feet, 10.0 inches (5.131 meters) long and 2 feet, 11.2 inches (0.894 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).
The bomber had a cruise speed of 544 knots (626 miles per hour/1,007 kilometers per hour) and a maximum speed of 1,147 knots (1,320 miles per hour/2,124 kilometers per hour) at 67,000 feet (20,422 meters). The B-58A had a combat radius of 4,225 nautical miles (4,862 statute miles/7,825 kilometers). Its maximum ferry range was 8,416 nautical miles (9,685 statute miles/15,586 kilometers).
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.

On 26 May 1961, The Firefly, flown by a different aircrew, set a speed record by flying New York to Paris, while enroute to the Paris Air Show, a distance of 3,626.46 miles in 3 hours, 19 minutes, 58 seconds, for an average of 1,089.36 mph.
Convair built 116 B-58s between 1956 and 1961. They were retired by 1970.
On 3 June 1961, the Blériot Trophy-winning crew of Murphy, Moses and Dickerson departed Le Bourget Airport aboard 59-2451 for the return trip to America. The B-58 crashed five miles from the airport. All three men were killed and the aircraft totally destroyed.

Convair B-36J-1-CF 52-2220 at NMUSAF, Wright-Patterson AFB, Ohio.
30 April 1959: Convair B-36J-1-CF Peacemaker, serial number 52-2220, landed at Wright-Patterson Air Force Base, Dayton, Ohio, completing the very last flight ever made by one of the giant Cold War-era bombers. It is on the collection of the National Museum of the United States Air Force.
Convair B-36J 52-2220 was among the last group of 33 B-36 bombers built. It was operated by an aircraft commander/pilot, co-pilot, two navigators, bombardier, two flight engineers, two radio operators, two electronic countermeasures operators and five gunners, a total 16 crewmembers. Frequently a third pilot and other additional personnel were carried.

Back (L-R):A.S. Witchell, J.D. McEachern, J.G. Parker and R. D. Norvell. (Jet Pilot Overseas)
The bomber is 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 9 inches (14.249 meters). The empty weight is 171,035 pounds (77,580 kilograms) and combat weight is 266,100 pounds (120,700 kilograms). Maximum takeoff weight is 410,000 pounds (185,973 kilograms).
The B-36J has ten engines. There are six air-cooled, supercharged 4,362.49 cubic-inch-displacement (71.49 liter) Pratt & Whitney Wasp Major C6 (R-4360-53) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. The R-4360-53 had a Normal Power rating of 2,800 horsepower at 2,600 r.p.m. Its Military Power rating was 3,500 horsepower at 2,800 r.p.m., and 3,800 horsepower at 2,800 r.p.m. with water injection—the same for Takeoff. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-53 is 9 feet, 9.00 inches (2.972 meters) long, 4 feet, 7.00 inches (1.397 meters) in diameter, and weighs 4,040 pounds (1,832.5 kilograms).
Four General Electric J47-GE-19 turbojet engines are suspended under the wings in two-engine pods. The J47 is a single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilonewtons).
The B-36J had a cruise speed of 203 miles per hour (327 kilometers per hour) and a maximum speed of 411 miles per hour (661 kilometers per hour) at 36,400 feet (11,905 meters) . The service ceiling was 39,900 feet (12,162 meters) and its range was 6,800 miles (10,944 kilometers) with a 10,000 pound (4,536 kilogram) bomb load. The maximum range was 10,000 miles (16,093 kilometers).

Designed during World War II, nuclear weapons were unknown to the Consolidated-Vultee engineers. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in two bomb bays. It could carry the 43,600 pound (19,776.6 kilogram) T-12 Cloudmaker, a conventional explosive earth-penetrating bomb, or several Mk.15 thermonuclear bombs. By combining the bomb bays, one Mk.17 25-megaton thermonuclear bomb could be carried.
For defense, the B-36J had six retractable defensive gun turrets and gun turrets in the nose and tail. All 16 guns were remotely operated. Each position mounted two M24A1 20 mm autocannons. 9,200 rounds of ammunition were carried.

6 March 1961: The B-52H is the final version of the Boeing B-52 Stratofortress intercontinental strategic bomber. There are discrepancies as to the date of its first flight, with sources varying by as much as eight months. One very reliable source writes that the flight took place on 20 July 1960. A U.S. Air Force publication says that it was in March 1961, and another source (Boeing) says that it was 6 March 1961. An article in The Kansas City Times confirms the date:
B-52H IS TEST FLOWN
Initial Flight Is Made by Bomber at Wichita
Wichita, March 6.(AP)—The first of this nation’s newest missile bombers, the global B-52H, took to the air in its initial flight today.
A 6-man test crew of the Boeing Airplane company manned the production model super bomber, which is capable of flying 650 miles an hour over an 11,000-mile range.
The bomber will carry four Douglas Skybolt missiles.
—The Kansas City Times, Vol. 124, No. 56, 7 March 1961, Page 21, Columns 7–8
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.
A fourth source identifies the aircraft in the photograph above, Boeing B-52H-135-BW Stratofortress 60-0006, (Boeing serial number 464-371) as the first B-52H to fly. The existence of a nice aerial portrait suggests that this may be correct.
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 B-52H is also 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. 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). Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF33-P-3 is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (1,769 kilograms).
The B-52H has a cruise speed of 525 miles per hour (845 kilometers per hour). It has a maximum speed of 632 miles per hour (1,017 kilometers per hour) at 23,800 feet (7,254 meters)—0.908 Mach. The service ceiling is 47,700 feet (14,539 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 was armed with a 20 mm M61A1 Vulcan 6-barreled rotary cannon in place of the four .50-caliber machine guns of the earlier variants. The gun was removed after 1991.
The B-52H was armed with a 20mm M61A1 Vulcan six-barreled rotary cannon 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 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 first of 102 B-52H Stratofortresses entered service on 9 May 1961. The last one, 61-0040, was rolled out 26 October 1962. Beginning in 2009, eighteen B-52H bombers were placed in climate-controlled long term storage at Tinker Air Force Base, Oklahoma. 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. In 2014, the entire fleet began a major avionics upgrade. B-52Hs remaining in the Air Force inventory will be upgraded with new engines, new radar, communications and navigation equipment, and will be redesignated B-52J. The B-52 is expected to remain in service until 2040.

60-0006, the first B-52H to fly, crashed while making a ground-controlled (GCA) approach to Wright Patterson Air Force Base, Dayton, Ohio, at 2:07 a.m., 30 May 1974. The bomber’s rudder and elevators failed. Although 60-0006 was destroyed, all seven airmen on board, Captains Charles Brown, Robert E. Smith, William G. Heckathorn, Paul C. Hoffman, 1st Lieutenants John D. Weaver, James R. Villines, and 2nd Lieutenant Robert E. Pace, survived the accident without serious injuries.

The bomber is powered by four General Electric F101-GE-102 turbofan engines, mounted in two-engine nacelles under the wing roots. These are rated at 17,390 pounds of thrust (23.578 kilonewtons) and produce 30,780 pounds (41.732 kilonewtons) with “augmentation.” The engine has two fan stages, a 9-stage axial-flow compressor and a 3-stage turbine. The F101-GE-102 is 15 feet, 0.7 inches (4.590 meters) long, 4 feet, 7.2 inches (1.402 meters) in diameter and weighs 4,460 pounds (2,023 kilograms).
“The Bone” has a maximum speed of Mach 1.2 at Sea Level (913 miles per hour, or 1,470 kilometers per hour). The service ceiling is “over 30,000 feet” (9,144 meters). The Lancer’s maximum range is “intercontinental, unrefueled.”
It can carry up to 84 Mk.82 500-pound (226.8 kilogram) bombs, 24 Mk.84 2,000-pound (907.2 kilogram) bombs or other weapons in three weapons bays. The B-1B was built with the capability to carry 24 B61 thermonuclear bombs, though, since 2007, the fleet no longer has this capability.
100 B-1B Lancers were built between 1983 and 1988. As of May 2018, 62 B-1B bombers are in the active Air Force inventory. The Air Force plans upgrades to the aircraft and plans to keep it in service until 2036.

Convair B-36J-75-CF Peacemaker, 52-2827, the last B-36 built. (U.S. Air Force)
The Last Peacemaker: This gigantic airplane, a Convair B-36J-75-CF Peacemaker, serial number 52-2827, was the very last of the ten-engine strategic bombers built by the Convair Division of General Dynamics at Fort Worth, Texas. It was completed 1 July 1954. On 14 August, it was delivered to the Strategic Air Command, 92nd Bombardment Wing, Heavy, at Fairchild Air Force Base, Washington. In April 1957, 52-2827 was assigned to the 95th Bombardment Wing, Heavy, at Biggs Air Force Base, El Paso, Texas.
The last one built, 52-2827 was also the last operational B-36.

On 12 February 1959, after 4 years, 5 months, 30 days service, the Air Force returned the bomber to Fort Worth. 52-2827 departed Biggs Air Force Base at 11:00 a.m., under the command of Major Frederick J. Winter. Other pilots were Colonel Gerald M. Robinson, commanding the 95th Wing, and Captain Wilson P. Smith. (Colonel Robinson flew as first pilot during the takeoff, while Major Winter flew the landing.) The bomber’s crew were hand-picked, and included two navigators, two flight engineers, an observer, two radio operators, two gunners and a crew chief. Ten newspaper, radio and television reporters were on board as well.

The B-36 touched down at Amon Carter Field at 2:55 p.m. The Peacemaker’s log book was closed out with a total of 1,414 hours, 50 minutes, flight time.
After a ceremony attended by thousands, the bomber was officially retired. A bugler blew “Taps,” and then the Peacemaker was towed away.
It was put on display at Amon Carter Field. After decades of neglect, the bomber was placed in the care of the Pima Air and Space Museum at Tucson for restoration and display.

Convair B-36J 52-2827 is one of 14 “Featherweight III” high altitude variants. It was built without the six retractable defensive gun turrets of the standard B-36, retaining only the two M24A1 20 mm autocannons in the tail. This reduced the crew requirement to 13. It is 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 9 inches (14.249 meters). The empty weight is 166,125 pounds (75,353 kilograms) and loaded weight is 262,500 pounds (119,068 kilograms). Maximum takeoff weight is 410,000 pounds (185,973 kilograms).
The B-36J has ten engines. There are six air-cooled, supercharged 4,362.49 cubic-inch-displacement (71.488 liter) Pratt & Whitney Wasp Major C6 (R-4360-53) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. The R-4360-53 had a Normal Power rating of 2,800 horsepower at 2,600 r.p.m. Its Military Power rating was 3,500 horsepower at 2,800 r.p.m., and 3,800 horsepower at 2,800 r.p.m. with water injection—the same for Takeoff. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-53 is 9 feet, 9.00 inches (2.972 meters) long, 4 feet, 7.00 inches (1.397 meters) in diameter, and weighs 4,040 pounds (1,832.5 kilograms).
Four General Electric J47-GE-19 turbojet engines are suspended under the wings in two-engine pods. The J47 is a single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilonewtons).
The B-36J Featherweight III had a cruise speed of 230 miles per hour (370 kilometers per hour) and a maximum speed of 418 miles per hour (673 kilometers per hour). The service ceiling was 43,600 feet (13,289 meters) and its combat radius was 3,985 miles (6,413 kilometers). The maximum range was 10,000 miles (16,093 kilometers).
The B-36 was designed during World War II and nuclear weapons were unknown to the Consolidated-Vultee Aircraft Corporation engineers. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in the four-section bomb bay. It could carry the 43,600 pound (19,777 kilogram) T-12 Cloudmaker, a conventional explosive earth-penetrating bomb. When armed with nuclear weapons, the B-36 could carry several Mk.15 3.8 megaton thermonuclear bombs. By combining the bomb bays, one Mk.17 15-megaton thermonuclear bomb could be carried.

TDiA has received an number of comments recently regarding the safety of the Convair B-36 Peacemaker strategic bomber. Based on our research, out of the 384 built, 27 B-36s were lost in accidents between 1950 and 1957, amounting to just 7% of the fleet. 165 crew members were killed. The most common cause seems to be a fire following a landing gear collapse. The first, a B-36B, was lost on 14 February 1950. That incident is described at https://www.thisdayinaviation.com/13-february-1950/ . On 27 April 1951, a flight of four North Americaan Aviation F-51D Mustangs attacked a B-36D over Oklahoma. One fighter collided with the bomber, which crashed, resulting in the death of 12 of the 17 airmen on board. (The F-51D pilot was also killed.) 6 May 1951, a B-36D crashed while attempting to land in high winds at Kirtland AFB, New Mexico. 23 of 25 on board were killed. 22 August 1951, a taxiing RB-36E collided with a parked RB-36E, which was destroyed. No injuries. 29 January 1952, a B-36D landed short of the runway and skidded into a snow bank at Fairchild AFB, Washington. The aircraft was destroyed by fire, but there were no fatalities. 6 March 1952, a B-36F was destroyed by fire while parked. A fuel leak was caused when the left landing gear failed on landing. There were no fatalities. 15 April 1952, a B-36D overran the runway during a maximum weight takeoff at Fairchild AFB, WA, because flight control trim had been incorrectly set. The aircraft was destroyed by fire. 15 of 17 on board were killed. 28 May 1952, a B-36F returning to Carswell AFB after takeoff due to a loose cowling, crashed and caught fire when its landing gear collapsed on landing, 7 on board were killed. 4 August 1952. A B-36F was destroyed by fire while parked at Carswell AFB. While being fueled, gasoline overflowed from a fuel vent and was ignited by a ground power unit. No injuries or deaths. 13 February 1953, a B-36H was misdirected during a GCA approach to Goose Bay, Labrador. It crash landed on a hill. 2 of 17 on board were killed. 5 August 1952, a modified B-36D being flown by a Convair crew crashed in the ocean west of San Diego, California, when it’s number 5 engine caught fire, which then spread to the rest of the wing. 7 of 8 crewmen bailed out while the pilot remained at the controls to guide the bomber away from the populated area. He was killed. 1 crewman drowned. 4 crewmen received minor injuries. 18 February 1953, an RB-36H was destroyed by fire when it’s landing gear collapsed during landing at Walker AFB, New Mexico. Of the 22 on board there were no fatalities. 18 March 1953, an RB-36H was destroyed when it hit a hill in Labrador. The aircraft was off course and one-and-a-half hours ahead of schedule. All 23 on board were killed. 5 August 1953, an RB-36H went down in the Atlantic Ocean (cause not discovered at this time.) 19 of 23 on board were killed. 11 December 1953, a B-36D crashed into a mountain in poor visibility while on approach to Biggs AFB, Texas. (Not in GCA radar contact). 9 of 9 on board were killed. 26 February 1954, at Fairchild AFB, the landing gear of a taxiing B-36D collapsed, resulting in the aircraft being destroyed by fire. No fatalities among the 20 on board. 29 March 1954, a B-36D crashed while practicing a takeoff abort at Fairchild AFB. All 7 on board were killed. 27 August 1954, an RB-36H making its sixth practice night approach at Ellsworth AFB hit an obstruction on a hill with its left wing and crashed. (Obstruction lights were inoperative due to a lightning strike.) 26 of 27 on board were killed. [Altimeter was in error, GCA was out of calibration, resulting in the aircraft being 150 feet lower on the glide slope than it should have been.] 8 February 1955, a B-36D landed short of the runway during a practice landing at Carswell AFB, Texas. Landing gear was sheared off and the aircraft damaged beyond economical repair. No fatalities. 6 March 1955, a B-36D landing at Loring AFB, Maine, hit a wingtip on a snowbank, resulting in the aircraft being destroyed by fire. No fatalities but some (unknown how many) serious injuries among the 11 on board. 25 May 1955, a B-36J disintegrated in flight during a thunderstorm/tornado near Sterling City, Texas. All 15 on board were killed. (Lost outboard wing panels and all tail surfaces. Impacted in level attitude with little forward motion.) 4 January 1956, an RB-36H crashed on landing at Ellsworth AFB, South Dakota after uneven power reduction. Destroyed by fire. No fatalities. 19 January 1956, a B-36D made a hard landing at Biggs AFB, Texas. No fatalities. Aircraft damaged beyond economical repair. 15 November 1956, a B-36H lost power on takeoff from Lowry AFB, Colorado, due to fuel starvation. It crashed one mile short of the runway attempting an emergency landing at Stapleton Airport, Denver. Aircraft destroyed by fire. No fatalities among 21 on board. 6 June 1957, a B-36H was damaged beyond economical repair while flying through a thunderstorm near Carswell AFB, Texas. No fatalities. 9 November 1957, an RB-36H was destroyed by fire while parked at Ramey AFB, Puerto Rico. No fatalities… A major incident occurred 1 September 1952, when a tornado struck Carswell AFB. 61 B-36s on the ground were damaged. Most were repaired and returned to service within two weeks.
