The Antonov A-40 Krylya Tanka (Russian: ÐºÑ€Ñ‹Ð»ÑŒÑ Ñ‚Ð°Ð½ÐºÐ°, meaning "tank wings") was a Soviet attempt to allow a tank to glide into a battlefield after being towed aloft by an airplane, to support airborne forces or partisans. A prototype was built and tested in 1942, but was found to be unworkable. This vehicle is sometimes called the A-40T or KT.
