3. B-29 Super Fortress (US)
This was the largest bomber to enter the war. It was mostly used in the Pacific region but soon developed a reputation all over the world for dropping the atomic bombs at Hiroshima and Nagasaki.
A total of 3,970 Super Fortresses were built and operated by the US Army Air Forces, US Air Force and Royal Air Force.
The bomber decimated through Japanese cities and reduced them to rubble thanks to nighttime accuracy. It was operated by a crew of 10 and could cruise at 575 km/h. In addition, it could fly for 5230 km on a full tank. Later on, the bomber was used in the Korean War until it was retired in 1960.
