Boeing B-29 Superfortress
The B-29 Superfortress was manufactured from 1943 to 1946 and were designed for use in the Second World War. They were by far the most expensive weapons project that the United States undertook during World War II. With a four-engine prop, these planes were so effective in the war, that they were also used in the Korean War. When it was first produced, it was among the most highly technological aircraft in the sky and more money went into its design process compared to what went into the Manhattan Project.

Douglas XB-19
Up until 1946, the biggest aircraft which had been made and the United States Army Air Force used was the Douglas XB-19. As technology kept progressing, by 1949, the whole aircraft had been scrapped. This plane’s purpose was to test different design elements that could be used in oversized bombers. Once a prototype of the XB-19 had been created, technology had already surpassed what the aircraft had been equipped with, so it was deemed unsuitable.
