As World War II drew to a close, the Soviet government was well aware that todays allies would soon be tomorrows adversaries. This meant new bombers had to be developed for dealing strikes at the potential adversaries military and political centers. Having gained access to German jet aircraft technology and the men behind it in 1945, the Soviet Union put them to good use when developing its own jet bombers.The first jet bomber to fly in the USSR was the Junkers EF131. Built in 1946, it was based on the unconventional forward-swept wing Ju 287 V2, which had been captured in incomplete form.
