Torped 613 is wire-guided and has a dual passive and active sonar seeker head that sends back information through the guidance wire.

The torpedo was developed in the 1970s as a cooperation project between Denmark, Norway and Sweden.

The TP613 was developed during the late 1970s and early 1980s through a collaboration between the navies in Denmark, Norway and Sweden.

The weapon incorporates terminal homing and two-way wire guidance.

[2] Like the older Swedish Torped 61 introduced in 1968, it is driven by a bipropellant piston engine using high-test peroxide and alcohol, which gives long range and a minimum exhaust consisting of water vapor and carbon dioxide.
