Technology played a crucial role in determining the outcome of World War II. Much of it was developed during the interwar years of the 1920s and 1930s, some were developed in response to valuable lessons learned during the war, and some were beginning to be developed as the war ended.

Almost all types of technology were customized, major developments were:
- Weaponry: ships, vehicles, aircraft, artillery, rocketry, small arms; and biological, chemical, and atomic weapons
- Logistical support: vehicles necessary for transporting soldiers and supplies, such as trains, trucks, ships, and aircraft
- Communications and intelligence: devices used for navigation, communication, remote sensing, and espionage
- Medicine: surgical innovations, chemical medicines, and techniques
- Industry: the technologies employed at factories and production/distribution centers

PRESSURIZED CABINS
Flying at high altitude puts occupants of an aircraft at risk of hypoxia (poor oxygen levels in the blood), altitude sickness, decompression sickness and barotrauma (cause by pressure differences). Despite these risks, bombers at the start of WWII were only equipped with oxygen masks, which restricted movement and were prone to failure. Until the B-29 Super fortress was introduced in 1944, only experimental aircraft had been produced with pressurized cabins. For this plane, the Americans created the first cabin pressure system, with the nose and cockpit sections linked to the aft via a long tunnel, all pressurized. However, the bomb bays remained pressurized. Even so, this advancement meant the crew could move around in comparative comfort. After the war, the benefits of pressurized cabins were rolled out to passenger planes, allowing us all to fly at high altitudes in relative comfort

THE V-2
Hitler's second Vergeltungswaffe, or Vengeance Weapon, may have killed over 2,500 people (and 20,000 more died in the process of making it) but it was a key step forward in putting a flag on the moon, as well as developing GPS, Google Earth and satellite communications.
While the V-1 was a relatively crude guided missile, the V-2 was an astonishingly advanced weapon. The world's first intercontinental ballistic missile had a range of 200-225 miles, reached an altitude of up to 60 miles and could strike London just three minutes after its launch in Holland.
