The Torped 47 or SLWT (Saab’s Lightweight Torpedo) is a new lightweight 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 as a replacement for the Torped 45.[2]

The torpedo is designed for the Swedish Navy and it will be equipped with both a passive and an active homing device and use wire communication like the Torpedo 45, using a galvanic wire (later also an optical wire).[2]

Torpedo 47 can be launched from a variety of platforms including stationary, surface vessels, submarines, helicopters and airplanes like Saab Swordfish MPA.[3][4] It is specifically designed to operate against littoral submarine 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.[2]

SLWT will be delivered to the Finnish Navy as part of the Squadron 2020 program[5] and will be installed on the Hamina-class during MLU and the new Pohjanmaa-class corvette.[6][7]

In October 2022 Saab delivered the first Torped 47 to the Swedish FMV. This is the final step before it will be introduced in the Swedish Navy.[2][8]
