The B-52 Stratofortress
The B-52 (aka ‘aluminum overcast’ or BUFF – Big Ugly Fat Fellow (or cruder term for the 2nd ‘F’...) has been flying for over 50 years now and by all rights, looks to remain in the inventory until around 2040. Volumes have been (and undoubtedly will be) written of the BUFF’s exploits, from forming one of the three legs of the strategic triad, to conventional attack in
The BUFFs’ Beginnings
Even as it was entering frontline service, the B-36 was already on the threshold of obsolescence in the post-WWII years. In July of 1948 Boeing designers were penning what eventually would become the XB-52. As originally conceived, the XB-52 had straight wings and would be powered by six Wright T-35 turboprops. As the design morphed, the wings became swept and eventually the turboprops replaced by eight of the new Pratt & Whitney J57-P-3 turbojets. This final design was approved by the Air Force in October 1948 and on 29 November 1951; the XB-52 was rolled out from Boeing’s

The BUFF – First Person Singular
Your Humble Scribe has had several up close/personal encounters with the BUFF. After all, growing up in the shadow of SAC HQ how could one not? Setting aside for the moment the first glimpse of the BUFF in a flyover at the annual Offutt air show (which to YHS, was more sacred than a pilgrimage to Mecca), the first real encounter was with the B-52B at the SAC museum, which used to be located on the outlying regions of Offutt. There, a collection of aircraft lay under the
Fast forward a decade (or so) and our subject now finds himself roughly mid-way through what would be a 9 month deployment, most of which was spent drilling holes on Gonzo station (off
Oh yes, it also starred in one of YHS’ top 10 favorite movies...
Over the course of its lifetime the BUFF has been responsible for dropping the mundane and the exotic (though by all accounts, a toilet was not included). Besides the usual iron bombs, the BUFF also counted:
- The largest-yield nuclear weapon in the
inventory – the Mk 41 thermonuclear bomb. The Mk-41 was the only three-stage thermonuclear weapon ever deployed by the US It weighed 4,840 kilograms and was 3.8 meters long. It could be carried by the B-52 or the B-47. While about 500 were built from September 1960 to June 1962, retirement began in November 1963 and the last B41s withdrawn in July 1976. A 25 mt yield for the B41 would give it a yield-to-weight ratio of 5.2 kilotons/kilogram. U.S.
- The Lockheed D-21 (Project Tagboard): An unmanned or "drone" aircraft designed to carry out high-speed, high-altitude strategic reconnaissance missions over hostile territory. It is a product of the Lockheed "Skunk Works" program that developed the A-12, YF-12, and SR-71 "Blackbird" manned aircraft in the 1960's. The D-21 ramjet-powered reconnaissance drone was powered by a Marquardt RJ-43-MA-11 ramjet. Cruising at Mach 3.3 at an altitude of 90,000 feet, the D-21 had a range of over 3400 nautical miles. The D-21 was guided by an inertial navigation system on a pre-programmed flight profile. Originally, the D-21 was designed to be launched from the back of a modified A-12 (redesignated M-12) carrier aircraft. The first flight of the D-21/M-12 combination took place on December 22, 1964, but the first D-21 release from an M-12 did not occur until March 5, 1966. two more launches were successful, but on July 30, 1966, a D-21 collided with the M-12 after release, destroying both aircraft and resulting in the death of one of the M-12's crew members. No further "piggyback" launches were attempted. A new launch system was developed using modified B-52H aircraft as carriers. The new D-21 configuration (designated D-21B) had dorsal mounting hooks for carriage under the B-52's wing, and a solid rocket booster for the initial acceleration required to start the ramjet engine. The first launch from a B-52 took place on November 6, 1967, but the D-21 crashed. Several flights followed in 1968 with mixed success.
- AGM-84D Harpoon: A BUFF armed to the gills w/Harpoons was a CICOs best friend when running ASUW in the
North Atlanticduring the Cold War. With lots of loiter time, tough ECM and 8-12 of these hummers slung on wing mounted pylons, one could run some pretty righteous war-at-sea strikes, overloading the bad guys with multiple axis attacks. Between these guys and organic assets (i.e., airwing A-7/A-6’s), we were going hunting. Kirov
- Test vehicles: “Double Balls 8” (referring to the a/c serial # - 0008) was the famous NB-52B that was a fixture around Edwards AFB and used as the mother ship for the X-15 program. Following in the pattern set by the B-29/X-1 team, the NB-52 carried the X-15 to launch altitude for its test flights. But with the end of the X-15 program, the NB-52 continued to fly with a variety of vehicles for test. The NB-52B launched the three X-15 hypersonic rocket planes and the Northrop HL-10, Northrop M2-F2/F3, Martin Marietta X-24A and Martin Marietta X-24B lifting bodies. It simulated the steep, power off approach to landing used by the Space Shuttles. It assisted in the collection of data about wake turbulence from large aircraft. It served as an air-to-air gunnery target. It launched 3/8-scale F-15 Remotely Piloted Research Vehicles (RPRV), a Ryan Firebee II drone, Ryan Firebee based Drones for Aeroelastic Structures Testing (DAST), and the Highly Maneuverable Aircraft Technology (HiMAT) RPRVs. It dropped the 48,000-pound Space Shuttle Reusable Booster Drop Test Vehicle (SRB/DTV) and it released a simulated F-111 crew module from its bomb bay to evaluate new parachute recovery systems. It was the first airplane to launch a satellite into orbit on the Orbital Sciences Pegasus booster. It tested the drag chute used to decelerate space shuttle orbiters. It tested pollution reducing fuel additives with a pair of jet engines mounted under its bomb bay. It launched the X-38 Space Station Crew Return Vehicles and the X-43A Hyper-X Supersonic Combustion Ramjet. A unique aspect for the NB-52 was the tally board for each mission flown. Besides the usual suspects (X-15, Pegasus, etc.) there are a few gems of wry humor to be found sprinkled around.
- B-52 flies unlike other aircraft. Shortly after take-off, as it gains speed, the nose dips and it climbs in an initial nose-low attitude, a consequence of high camber of its wing in the full flaps configuration. This looks strange to most people, who are used to seeing aircraft take off nose-high.
- An aircraft of this massive size, power and weight necessitates hydraulically boosted control surfaces. However, B-29 Superfortress pilots, who were used to using brute force from the human body to actuate the control surfaces, would be transferred to the B-52, which had hydraulic controls. Therefore, strong springs are used to help imitate the control feel of the older aircraft. As a result the B-52 is a physically demanding aircraft to fly.
- The B-52's skin looks wrinkled when the aircraft is on the ground. In flight, the wrinkles disappear as the wing loading causes the wings and airframe to flex to in-flight configurations.
- The ejection seats for the lower-deck crewmembers, the Navigator and Radar Navigator, eject downwards. Because of this, these crewmembers cannot eject at an altitude of 200 feet or less. A Navigator and a Radar Navigator from Fairchild AFB both survived a downward ejection at approximately 200 feet above ground level in a training accident near
on the evening of October 20, 1984. The upper deck crewmembers (Pilot, Copilot, and Electronic Warfare Officer) have seats which eject them upwards. Their seats work at any altitude, as long as the airspeed is at least 90 knots. This is necessary to inflate their parachutes, since their ejection seats are blast propelled and not rocket propelled, and are not 0-0 certified as are more modern ACES-II ejection seats.

- There is a story told by many B-52 pilots that sums up the aircraft: "The B-52, with its familiar wrinkled fuselage sides, has enough metal to make 10,000 garbage cans. The wiring in the Stratofortress is equivalent to five miles of baling wire. Its engines are as powerful as eight locomotives. And that's the way it flies, like eight locomotives, pulling ten thousand garbage cans with five miles of baling wire!"

, has a patch on the cockpit. The damage was caused by impact with an American Bald Eagle during landing. Nebraska
- As part of the 1991 Strategic Arms Reduction Treaty between the
United Statesand Russia, 365 B-52Gs were flown to the Aerospace Maintenance and Regeneration Centerat Davis-Monthan Air Force Base in . The bombers were stripped of all usable parts, then chopped into five pieces by a 13,000-pound steel blade dropped from a crane. The guillotine sliced four times on each plane, severing the wings and leaving the fuselage in three pieces. The ruined B-52s remained in place for three months so that Russian satellites could confirm that the bombers had been destroyed, after which they were sold for scrap. Arizona
- During the early morning of January 17, 1991 the first day of
Storm a B-52G (aircraft 0248) was fired upon by an F-4G Wild Weasel. The B-52's tail gunner locked his tail gun radar on the Wild Weasel mistaking it for an Iraqi MIG. The Wild Weasel immediately detected the B-52 tail gun radar and misidentified the radar signature as an Iraqi Anti-Aircraft Artillery (AAA) site. The F-4G Wild Weasel crew fired a single AGM-88 HARM anti-radiation missile and watched in horror as it headed not towards the non-existent Iraqi AAA site, but to one of the B-52 bombers it was tasked with protecting. Luckily the missile failed to hit the plane, but instead detonated directly behind the bomber. The shrapnel and missile debris damaged the tail section of the B-52G. It ripped off everything aft of the vertical stabilizer. This included much of the tail gun system, the aft Electronic Warfare suite, and the drag chute. The B-52G was able to return safely to the operation Desert . It was later fully repaired at Anderson Air Force Base on islandof Diego Garcia Guamwhere it was renamed "IN HARM's WAY". The tail gunner position was subsequently eliminated from the entire B-52 fleet.
