The Bartini A-57 was an experimental Soviet bomber of the mid-1950s that was designed by Robert Ludvigovich Bartini to take-off and land on water. The aircraft was never put into production. The A-57 was equipped with a lift jet (similar to VTOL aircraft today) facing downward to assist its take-off from the surface of the ocean. It was intended to refuel from submarines out at sea. The bomber had a long, slender delta wing called the Bartini Wing. It was tested in wind tunnels, but the project was scrapped in 1957 before actual production could begin. Possibly because the Soviet Government after the launch of Sputnik 1 believed that the new R-7 ICBM made bombers less required and decided the Tu-95 would do and that the A-57 project was too expensive and that such an aircraft was not needed
