In 1958, as a part of the defense materiel plan for the 1960s, it was decided that the Swedish army should acquire a new tank to replace the Centurion. This was more or less a response to the development of the new generation of tanks in the west, such as the Leopard 1 and the Chieftain. Although Sweden had interest in these foreign designs (most notably the Chieftain), it was decided that a native design would be preferable. Based on different ideas about tank development at the time, these designs were categorized as three different classes of tank.
Type A (Based on the English and American model of building heavy and well armored tanks)
Type T (Based on the French and German idea of a lightly armored tank with good mobility)
Type S (Original Swedish concept of a turretless tank that would combine the armor of a heavier tank but with the weight and mobility of a lighter one)
However these were not just categories for foreign tank designs, but these also became the basis for three Swedish proposals called Strv A, Strv T and Strv S.
