Torped 613 is an older heavyweight torpedo still in use by the Swedish Navy. It is wire-guided and has a passive sonar sensor, which sends back information through the wire. The torpedo was developed in the 1970s as an cooperation project between Denmark, Norway and Sweden. Testing was done during the period 1981-1983.

As the older Swedish version Torped 61 introduced in the mid 1960s, it is driven by alcohol and hydrogen peroxide, which gives long range and a minimum exhaust trail.

The torpedo is planned to be replaced by the more modern Torped 62.
