Warrior Maven Video Analysis Above: Air Force Fast-Tracks New Air Dropped Weapons

During more than five decades of operational service, the Boeing B-52 heavy bomber has been the backbone of the strike capability of the U.S. Air Force. Its long range, ability to operate at high altitudes and capability to carry nuclear or precision-guided conventional ordnance to any point on the globe, has made it a key component of nuclear deterrence and U.S. National Security Strategy.
The B-52 is a long-range, heavy bomber that can perform a variety of missions. The bomber is capable of flying at high subsonic speeds at altitudes up to 50,000 feet. It can carry nuclear or precision guided conventional ordnance with worldwide precision navigation capability.
DEVELOPMENT AND DESIGN
Born of specifications for a new heavy bomber presented by Air Materiel Command in 1945, the first iteration of what would become the B-522, was the Boeing 464-40 created in 1946. This airframe was powered by turboprop engines, as jet engines were not yet seen as reliable or fuel efficient enough for long- range missions.
As development continued through the end of the decade, the project became the keystone for the fledgling U.S. Air Force’s Strategic Air Command under the direction of Gen. Curtis LeMay. At his insistence, the XB-52 and YB-52, which had more operational equipment, featured 35-degree swept wings with eight Westinghouse turbojet engines.

The YB-52 first took flight in April 1952 and subsequent ground and flight testing lead the Air Force to order 282 of the new heavy bombers, beginning with the delivery of three B-52As and 10 B-52Bs by 1954.
During the rollout ceremony, Air Force Chief of Staff Gen. Nathan Twining described the B-52 as “the long-rifle of the air age.”
The B-52 has since received many upgrades to communications, electronics, computing and avionics on the flight deck, as well as engines, fuel capacity and the weapons bay. These upgrades enable the B-52H to integrate into the new digital battlefield and precisely deliver a large array of weapons, from conventional, nuclear and smart bombs to conventional or nuclear cruise missiles, on targets anywhere in the world.

The use of aerial refueling gives the B-52 a range limited only by crew endurance.
Further development included a reconnaissance variant, as well as a model used as a launch platform for 93 NASA X-15 missions to explore the boundaries of space. A B-52H is currently used for launching other research vehicles by NASA’s Dryden Flight Research Center in California.
A total of 744 B-52s were built with the last, a B-52H, delivered in October 1962.

In a conventional conflict, the B-52 can perform strategic attack, close-air support, air interdiction, offensive counter-air and maritime operations.
Throughout the Cold War, B-52s were a cornerstone of the Nuclear Triad, which was comprised of nuclear missile submarines, Intercontinental Ballistic Missiles and bombers capable of delivering nuclear bombs.

Throughout the Cold War B-52s were continuously airborne on alert patrols armed with nuclear weapons should hostilities erupt with the Soviet Union. These missions ended in 1991.
During the Vietnam War, beginning with Operations Arc Light and Rolling Thunder in 1965 and concluding with Operations Linebacker and Linebacker II in 1972, B-52s carried out various bombing campaigns.

During Operation Desert Storm in 1991, B-52s flew over 1500 sorties and delivered 40 percent of all the weapons dropped by coalition forces. They struck wide-area troop concentrations, fixed installations and bunkers, and decimated the morale of Iraq’s Republican Guard.
They also bombed targets in Yugoslavia during Operation Allied Force in 1999 and Operations Enduring Freedom in Afghanistan in 2001 and Iraqi Freedom in 2003, providing close air support through the use of precision guided munitions. They have most recently engaged in missions against ISIL targets in Syria as part of Operation Inherent Resolve.
All B-52s can be equipped with electro-optical viewing sensors, a forward-looking infrared (FLIR) and advanced targeting pods to augment targeting, battle assessment, and flight safety, further improving its combat ability, day or night and in varying weather conditions utilizing a variety of standoff weapons, such as laser-guided bombs, conventional bombs and GPS-guided weapons.

The refueling was part of exercise Immediate Response, which included a three-ship formation of KC-135s delivering a total of 180,000 pounds of fuel to the sole bomber. The KC-135 was designed and built during the Cold War specifically to deliver fuel to the B-52. (U.S. Air Force photo/Tech. Sgt. Austin M. May)
DID YOU KNOW?
- The B-52 is capable of dropping or launching the widest array of weapons in the U.S. inventory, including gravity bombs, cluster bombs, precision guided missiles and joint direct attack munitions.
- Current engineering analyses show the B-52’s life span to extend beyond the year 2040.
- B-52s also assist the Navy in ocean surveillance.
- The lower deck crew of the B-52, the navigator and radar navigator, eject downward.
- In 1972, a B-52 tail-gunner, Albert Moore, shot down a MiG-21 over Vietnam. It was the last recorded bomber-gunner to shoot down an enemy aircraft.
- After the collapse of the Soviet Union in 1991, 365 B-52s were destroyed under the Strategic Arms Reduction Treaty. The aircraft were stripped of usable parts, chopped into five pieces with a 13,000 pound steel blade and sold for scrap at 12 cents per pound.
