Technology during World War II

<a href="/facts/Technology/9Uav5WVR">Technology</a> played a significant role in <a href="/facts/World_War_II/2efV5L1U">World War II</a>. Some of the technologies used during the war were developed during the interwar years of the 1920s and 1930s. Many were developed in response to needs and lessons learned during the war, and others were beginning to their development as the war ended. Wars often have major effects on peacetime technologies, but World War II had the greatest effect on the everyday technology and devices that are used today. Technology also played a greater role in the conduct of World War II than in any other war in history, and had a critical role in its outcome.
Many types of technology were customized for military use, and major developments occurred across several fields including:

<ul><li>Weaponry: ships, vehicles, submarines, aircraft, tanks, artillery, small arms; and biological, chemical, and atomic weapons</li>
<li><a href="/facts/Logistical_support/0Hr2w55W">Logistical support</a>: vehicles necessary for transporting soldiers and supplies, such as trains, trucks, tanks, ships, and aircraft</li>
<li>Communications and intelligence: devices used for <a href="/facts/Remote_sensing/pj2crmGs">remote sensing</a>, navigation, communication, <a href="/facts/Cryptography/e94PEVau">cryptography</a> and <a href="/facts/Espionage/oaDJ5fAd">espionage</a></li>
<li>Medicine: surgical innovations, chemical medicines, and techniques</li>
<li>Rocketry: guided missiles, medium-range ballistic missiles, and automatic aircraft</li></ul>
Military weapons technology experienced rapid advances during World War II, and over six years there was a disorientating rate of change in combat in everything from aircraft to <a href="/facts/Small_arms/GuHx4aGE">small arms</a>. Indeed, the war began with most armies using some technology that had changed little from <a href="/facts/Technology_during_World_War_I/ALY8Qzhb">that of World War I</a>, and in some cases, had remained unchanged since the 19th century. For instance <a href="/facts/Cavalry/BstsEn1G">cavalry</a>, <a href="/facts/Trench_warfare/GXDoLeRJ">trenches</a>, and World War I-era <a href="/facts/Battleship/PjjTspo5">battleships</a> were normal in 1940, but six years later, armies around the world had developed <a href="/facts/Jet_aircraft/esXNnbbg">jet aircraft</a>, <a href="/facts/Ballistic_missile/Pl6juY73">ballistic missiles</a>, and even <a href="/facts/Atomic_weapons/QVdBcMdm">atomic weapons</a> in the case of the United States.
World War II was the first war where military operations often targeted the research efforts of the enemy. This included the exfiltration of <a href="/facts/Niels_Bohr/ydLPvQXT">Niels Bohr</a> from German-occupied Denmark to Britain in 1943; the sabotage of <a href="/facts/Norwegian_heavy_water_sabotage/UMooUmCb">Norwegian heavy water production</a>; and the bombing of <a href="/facts/Bombing_of_Peenemunde_in_World_War_II/TutGfqbu">Peenemunde</a>. Military operations were also conducted to obtain intelligence on the enemy's technology; for example, the <a href="/facts/Bruneval_Raid/vvJBdqFE">Bruneval Raid</a> for German radar and <a href="/facts/Operation_Most_III/nFTPMbBx">Operation Most III</a> for the German V-2.
