Douglas B-22
The Douglas B-18 Bolo is an American heavy bomber which served with the United States Army Air Corps and the Royal Canadian Air Force (as the Digby) during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2, to replace the Martin B-10. By 1940 standards, it was slow, had an inadequate defensive armament, and carried too small a bomb load. A B-18 was one of the first USAAF aircraft to sink a German U-boat, on 22 August 1942 in the Caribbean. By 1942, surviving B-18s were relegated to antisubmarine, training and transport duties. Design and development In 1934, the United States Army Air Corps requested for a twin-engine heavy bomber with double the bomb load and range of the Martin B-10 then entering service. During the evaluation at Wright Field the following year, Douglas offered its DB-1. It was competing against the Boeing Model 299 (later developed into the Boeing B-17 Flying Fortress) and Martin 146. While th ...

Heavy Bomber
Heavy bombers are bomber aircraft capable of delivering the largest payload of air-to-ground weaponry (usually bombs) and longest range (takeoff to landing) of their era. Archetypal heavy bombers have therefore usually been among the largest and most powerful military aircraft at any point in time. In the second half of the 20th century, heavy bombers were largely superseded by strategic bombers, which were often smaller in size, but had much longer ranges and were capable of delivering nuclear bombs. Because of advances in aircraft design and engineering — especially in powerplants and aerodynamics — the size of payloads carried by heavy bombers has increased at rates greater than increases in the size of their airframes. The largest bombers of World War I, the four engine aircraft built by the Sikorsky company in the Soviet Union, could carry a payload of up to of bombs. By the middle of World War II even a single-engine fighter-bomber could carry a bomb load, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tucker Gun Turret
The Tucker gun turret was a fast-traversing electrically powered gun turret widely described as having been mounted on World War II bombers and on some ground vehicles and small naval vessels like US Navy PT boats. American industrialist Preston Tucker first developed the turret for the experimental Tucker armored car in 1938. Steve Lehto and Jay Leno, in their biography of Tucker, assert that it is a misconception that Tucker's turret was widely used on US bombers during the war. They assert that different manufacturers were each assigned contracts to develop different turrets for different planes, and that Tucker's firm was to build turrets for the Douglas B-18 Bolo. In the end no Tucker turrets equipped any bombers. When Tucker was under investigation by the Security and Exchange Commission, a half-hour film entitled '' Tucker: The Man and his Car'' was prepared and shown to the Commission members. Lehto and Leno described the film's narrator "gushing" over Tucker and noted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowry Field
Lowry Air Force Base (Lowry Field in 1938–1948) is a former United States Army Air Forces (USAAF) training base during World War II and a United States Air Force (USAF) training base during the Cold War, serving as the initial 1955–1958 site of the U.S. Air Force Academy. It is a U.S. Formerly Used Defense Site (B08CO0505). Background The City of Denver, Auraria, and Highland was chartered as the 1859 territorial capital after the start of the 1858 Pikes Peak Gold Rush; and the 1887 Fort Logan was established in the modern Denver Metropolitan Area. East of the state capital, military training at Montclair, Colorado, began at the future airfield when the 1887 Jarvis Hall Military School opened. Montclair was incorporated into Denver in 1903 and Jarvis Hall burned down in 1904. At the military school site the 'Agnes PhippsMemorial Sanatorium was established as a tuberculosis hospital in 1904 at 520 Rampart Way (cf. "East 6th Avenue and Quebec Street") by Lawrence C. Ph ...
