Torpedo 45 is a 400 mm torpedo intended for ASW and surface targets, providing multiple-target active/passive homing combined with wire guidance. It is designed and manufactured by Saab Dynamics in Skandinavia.

Versatile and flexible[edit | edit source]

Torpedo 45 can be launched from a variety of platforms including stationary, surface vessels, submarines and helicopters.

A proud legacy[edit | edit source]

The Torpedo 45 is based on the experience gathered from the well proven 43-series of torpedoes.

Features[edit | edit source]

The Torpedo 45 is an ASW lightweight torpedo that can be used against shallow-water targets and surface vessels. It is controlled using wire guidance and has a hydro-acoustic homing system for the final phase. The torpedo has features that are unique for lightweight torpedoes.

Standard features[edit | edit source]

  • Torpedo 45 combines wire guidance and homing control
  • It can be launched from submarines, surface vessels and helicopters
  • It can be wire-guided from a flying or hovering helicopter (no parachute necessary)
  • Its warhead has a main charge large enough to take out any conventional submarine or seriously damage light surface vessels

Exercise launchings[edit | edit source]

In exercise torpedo launches, the warhead is replaced by an exercise head carrying identical homing equipment. Instead of explosives, the exercise head has a tape recorder for logging a number of torpedo functions, communication with fire-control and hit indications. After each run, the recordings are analysed and torpedo and fire-control functions are checked.
