Strv 103-0

A contract for the production of a turretless vehicle was concluded with the Bofors company in 1960. A total of 10 prototypes of the "zero series" were produced. The vehicles differed from the mass-produced Strv 103 in weaker armor and engine, as well as in the commander's cupola. In 1964, the vehicles were used as a basis for the Strv 103A production.
