Cryptanalysis of the Enigma bombes were, however, very fast and the most successful. They were extensively used by Bletchley Park over teleprinter links (using the Combined Cipher Machine) to OP-20-G for both 3-rotor and 4-rotor jobs. Although the German army, SS, police, and railway all used Enigma with similar procedures, it was the "Luftwaffe" (Air Force) that was the first and most fruitful source of Ultra intelligence during the war. The messages were decrypted in Hut 6 at Bletchley Park and turned into intelligence reports in Hut 3. The network code-named ‘Red’ at Bletchley Park was broken regularly and quickly from 22 May 1940
Technology during World War II also developing an atomic Bomb, however, it floundered due to lack of resources despite gaining interest from the government. The collaboration between the British and the Americans led to the 1958 US-UK Mutual Defence Agreement between the two nations, whereby American nuclear weapons technology was adapted for British use. Electronics rose to prominence quickly in World War II. The British developed and progressed electronic computers which were primarily used for breaking the “Enigma” codes, which were Nazi secret codes. These codes for radio messages were indecipherable to the Allies. However, the meticulous work of code breakers based at Britain’s Bletchley
