Stridsvagn 74 (strv 74) was a Swedish tank in use with the Swedish Army from 1958 to 1984. It was a modification of the older stridsvagn m/42 which was phased out of service in the 1950s. Instead of scrapping the vehicles altogether, the chassis were used to build a new tank which could be used as a supplement to the newly bought stridsvagn 101.
