771st Bombardment Squadron
The 771st Bombardment Squadron is a former United States Army Air Forces unit. The squadron was activated in 1943, and became one of the earliest Boeing B-29 Superfortress units. It moved to the China Burma India Theater in April 1944 and participated in the first attack on the Japanese Home Islands since the 1942 Doolittle Raid in June 1944. In August 1944, it earned a Distinguished Unit Citation. It was inactivated on 12 October 1944, when the Army Air Forces reorganized its very heavy bomber groups to consist of three, rather than four squadrons. History Training in the United States The squadron was first activated on 1 July 1943 at Smoky Hill Army Air Field, Kansas as one of the four original squadrons of the 462d Bombardment Group, and was intended to be one of the first units to fly the Boeing B-29 Superfortress.Maurer, ''Combat Squadrons'', pp. 746–747 Smoky Hill was one of four bases chosen for B-29 training based on their proximity to Boeing's factory at Wich ...

B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 b ...

Martin B-26 Marauder
The Martin B-26 Marauder is an American twin-engined medium bomber that saw extensive service during World War II. The B-26 was built at two locations: Baltimore, Maryland, and Omaha, Nebraska, by the Glenn L. Martin Company. First used in the Pacific Theater of World War II in early 1942, it was also used in the Mediterranean Theater and in Western Europe. After entering service with the United States Army aviation units, the aircraft quickly received the reputation of a " widowmaker" due to the early models' high accident rate during takeoffs and landings. This was because the Marauder had to be flown at precise airspeeds, particularly on final runway approach or when one engine was out. The unusually high 150 mph (241 km/h) speed on short final runway approach was intimidating to many pilots who were used to much slower approach speeds, and when they slowed to speeds below those stipulated in the manual the aircraft would often stall and crash.Ethell 1995, p. 24 ...

Bombing Of Yawata (June 1944)
The Bombing of Yawata on the night of 15/16 June 1944 marked the beginning of the United States Army Air Forces (USAAF) strategic bombing campaign against the Japanese home islands during World War II and was the first such raid to employ strategic bombers. The raid was undertaken by 75 Boeing B-29 Superfortress heavy bombers staging from bases in China. Only 47 of these aircraft dropped bombs near the raid's primary target, the Imperial Iron and Steel Works at Yawata in northern Kyūshū, and little damage was caused. Five B-29s were lost in accidents during the operation and two were destroyed by Japanese aircraft. While the raid did not achieve its aims, it raised Japanese civilians' awareness that their country was being defeated and received positive media coverage in the United States. Intelligence gathered by the B-29s also revealed weaknesses in Japan's air defenses and the raid was the first of many on Japan. Yawata was attacked again by B-29s operating from China ...

Munitions
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and warheads). The purpose of ammunition is to project a force against a selected target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm NATO) that enable their use across different weapo ...

Bangkok
Bangkok, officially known in Thai language, Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand. The city occupies in the Chao Phraya River delta in central Thailand and has an estimated population of 10.539 million as of 2020, 15.3 percent of the country's population. Over 14 million people (22.2 percent) lived within the surrounding Bangkok Metropolitan Region at the 2010 census, making Bangkok an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy. Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew and became the site of two capital cities, Thonburi Kingdom, Thonburi in 1768 and Rattanakosin Kingdom (1782–1932), Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam, later renamed Thailand, during the late-19th century, as the country faced pressures from the ...

The Hump
The Hump was the name given by Allied pilots in the Second World War to the eastern end of the Himalayan Mountains over which they flew military transport aircraft from India to China to resupply the Chinese war effort of Chiang Kai-shek and the units of the United States Army Air Forces (USAAF) based in China. Creating an airlift presented the USAAF a considerable challenge in 1942: it had no units trained or equipped for moving cargo, and no airfields existed in the China Burma India Theater (CBI) for basing the large number of transports that would be needed. Flying over the Himalayas was extremely dangerous and made more difficult by a lack of reliable charts, an absence of radio navigation aids, and a dearth of information about the weather. The task was initially given to the USAAF's Tenth Air Force, and then to its Air Transport Command (ATC). Because the USAAF had no previous airlift experience as a basis for planning, it assigned commanders who had been key figures in ...

Airlift
An airlift is the organized delivery of supplies or personnel primarily via military transport aircraft. Airlifting consists of two distinct types: strategic and tactical. Typically, strategic airlifting involves moving material long distances (such as across or off the continent or theater), whereas a tactical airlift focuses on deploying resources and material into a specific location with high precision. Depending on the situation, airlifted supplies can be delivered by a variety of means. When the destination and surrounding airspace is considered secure, the aircraft will land at an appropriate airport or airbase to have its cargo unloaded on the ground. When landing the craft or distributing the supplies to a certain area from a landing zone by surface transportation is not an option, the cargo aircraft can drop them in mid-flight using parachutes attached to the supply containers in question. When there is a broad area available where the intended receivers have c ...

Bomber
A bomber is a military combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry (such as bombs), launching aerial torpedo, torpedoes, or deploying air-launched cruise missiles. The first use of bombs dropped from an aircraft occurred in the Italo-Turkish War, with the first major deployments coming in the World War I, First World War and World War II, Second World War by all major airforces causing devastating damage to cities, towns, and rural areas. The first purpose built bombers were the Italy, Italian Caproni Ca 30 and United Kingdom, British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure or reduci ...

Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed among the Air Corps, General Headquarters Air Force, and the ground ...
