The Boeing B-29 Superfortress was the largest bomber to enter production during World War II. The first prototype flew in September 1942. It was the first bomber to have a pressurized cabin and a central gunnery control system operated by remote control. It fought mainly in the Pacific Theatre and caused massive destruction on the Japanese Home Islands. It was heavily armoured and heavily armed, and when fully loaded it weighed in at 60 tons. With a 20,000lb bombload it had a range of 5,000 miles. The ultimate example of this aircrafts striking power was the dropping of the atom bomb on Hiroshima and Nagasaki in August 1945 and thus ending WWII.
