American military technology during World War II American military technology during World War II American military technologies developed during World War II became more advanced and specialized as the war progressed. The technologies produced ranged in complexity from relatively simple items such as small arms and armored vehicles, including tanks, to more complex items such as the atomic bomb. The latter, produced under the secretive Manhattan Project, proved to be an incredibly powerful weapon that revolutionized warfare and was used to end the war. Other technologies, such as the M4 Sherman tank, the M1 Garand and M1 Carbine, and the gas mask, were refinements on previously existing
Tanks of the U.S. in the Cold War The T95 Medium tank was developed from 1955 to 1959. These tanks used many advanced or unusual features, such as siliceous-cored armor, the APFSDS-firing 90 mm T208 smoothbore gun in a rigid mounting without a recoil system, a new transmission, and the OPTAC fire-control system, which incorporated the "T53 Optical Tracking, Acquisition and Ranging (OPTAR)" system, emitted pulsed beams of intense but incoherent infrared light. The M26 Pershing saw service in the Korean War. When the war began in June 1950, the four American infantry divisions on occupation duty in Japan had no medium tanks, had only light tanks. These
