Boeing B-29 Superfortress was a strategic bomber used by the United States Army Air Forces (USAAF) during World War II and the Korean War. The B-29 was designed by Boeing and developed in collaboration with Bell Aircraft, Consolidated Aircraft, and Douglas Aircraft. It was the largest production bomber of its time, with a wingspan of over 140 feet, and was powered by four Wright R-1820 radial engines. The B-29 played a significant role in the Pacific Theater of World War II, conducting bombing raids against Japan, including the Atomic bombings of Hiroshima and Nagasaki.

● Design and Development

The design of the B-29 was influenced by the Boeing XB-15 and the Boeing 314 Clipper, with a pressurized cabin and a remote-controlled General Electric defensive armament system. The B-29 was designed to fly at high altitudes, with a service ceiling of over 30,000 feet, and was equipped with a AN/APQ-13 radar system for navigation and bombing. The development of the B-29 was led by Edgar Gott, a renowned engineer at Boeing, and involved collaboration with other companies, including General Electric, Westinghouse Electric, and Sperry Corporation. The B-29 was also used as a testbed for new technologies, including the AN/ARN-6 radio compass and the AN/APW-11 radar system, developed by MIT Radiation Laboratory and Bell Labs.

● Operational History

The B-29 entered service with the United States Army Air Forces (USAAF) in 1944, with the first operational mission taking place on June 5, 1944, against Bangkok, Thailand. The B-29 was used extensively in the Pacific Theater, conducting bombing raids against Japan, including the Great Tokyo Firebombing and the Atomic bombings of Hiroshima and Nagasaki, which were carried out by the 509th Composite Group led by Paul Tibbets. The B-29 also played a significant role in the Korean War, conducting bombing raids against North Korea and China, including the Battle of Chosin Reservoir and the Battle of Heartbreak Ridge. The B-29 was also used by the Royal Air Force (RAF) and the Royal Australian Air Force (RAAF), with the RAF operating the B-29 as the Washington B.Mk 1.

● Variants

Several variants of the B-29 were developed, including the B-29A, which was an improved version of the B-29 with more powerful engines, and the B-29B, which was a variant with a different armament system. The KB-29M was a variant used for aerial refueling, and the WB-29 was a variant used for weather reconnaissance. The RB-29 was a variant used for reconnaissance, and the TB-29 was a variant used for training. Other variants included the B-29D, which was a proposed variant with a new engine, and the XB-39, which was a prototype with a different armament system, developed in collaboration with Lockheed Aircraft and North American Aviation.

● Specifications

The B-29 had a wingspan of 141 feet 3 inches, a length of 99 feet 1 inch, and a height of 27 feet 9 inches. It was powered by four Wright R-1820 radial engines, each producing 2,200 horsepower, and had a maximum speed of 357 miles per hour. The B-29 had a range of over 5,000 miles and a service ceiling of 33,600 feet. It was equipped with a General Electric defensive armament system, which included 12 M2 Browning machine guns and a M2 Browning cannon. The B-29 also had a AN/APQ-13 radar system for navigation and bombing, developed by MIT Radiation Laboratory and Bell Labs.

● Surviving Aircraft

Several B-29s have survived to the present day, including the B-29 Superfortress "Fifi", which is on display at the National Museum of the United States Air Force in Dayton, Ohio, and the B-29 Superfortress "Doc", which is on display at the Kansas Aviation Museum in Wichita, Kansas. Other surviving B-29s include the B-29 Superfortress "Raz'n Hell", which is on display at the Pima Air & Space Museum in Tucson, Arizona, and the B-29 Superfortress "Sentimental Journey", which is on display at the Commemorative Air Force in Mesa, Arizona. These aircraft are a testament to the significant role played by the B-29 in World War II and the Korean War, and are an important part of American aviation history, along with other notable aircraft like the North American P-51 Mustang and the Lockheed P-38 Lightning.
