Emil, also known as the Kranvagn, KRV or Emil Olsson was a tank developed secretly in Sweden during the early 1950s, Kranvagn, meaning mobile crane was a cover-name. The intention was to replace the Swedish Army's disparate tank fleet with a tank that could counter the Soviet IS series heavy tanks and be upgraded continuously. The initial design, in 1951, proposed mounting a 10.5 cm autoloader in an oscillating turret. Due to its size, weight and power to weight it was considered by many to be more of a medium tank than a heavy tank. The project was discontinued during development and only two chassis were built. They were later rebuilt and served as testing platforms for the Artillerikanonvagn 151 and Stridsvagn 103 projects.
