Russia want to building a secret bomber that would refuel by submarine.

During the mid 50’s the Soviets fooled the U.S. into believing that they had hundreds of Bison bombers ready to deploy but in real life they still lacked a way of reaching the US mainland. Their answer to this problem was the Bartini-57 a long range strategic bomber that could land on water and refuel by submarine mid road through its mission. The aircraft was the idea of Italian designer Robert Ludvigovich Bartini who built some of Russia’s most advanced aircraft among the 20’s and 50’s. But, Bartini’s bomber was annulled when Sputnik was launched in 1957 by his owner Sergei Pavlovich Korolev. The Soviets would then set their sights on missiles netter than bombers which triggered the Space Race.
