The Swedish Defence Materiel Administration (FMV) has placed an order with Saab for the provision of Saab Lightweight Torpedoes (SLWT) and associated torpedo tubes. The contract is valued at approximately SEK 1.3 billion, with deliveries set to commence in 2026.
The SLWT, designated Torped 47 by the Swedish Armed Forces, represents Sweden’s latest light torpedo system, designed to enhance the Swedish Navy’s capabilities.
This torpedo is primarily intended for deployment from submarines and surface vessels, but it is also adaptable for use on helicopters. This marks the second order for the SLWT from Sweden, following the initial deliveries to FMV that began in 2022.
The torpedo has been specifically engineered for the unique conditions of the Baltic Sea region, characterized by shallow waters and intricate topography and seabed, which impose significant requirements on submarine detection and identification, as well as on the torpedo’s navigation and communication systems.
“We are proud to continue to support Sweden in its efforts to modernise underwater weapon systems in order to protect the Baltic Sea region. This state-of-the-art system is providing the Swedish Armed Forces with increased capabilities, including torpedoes, spare parts, training systems, and technical support,” says Mats Wicksell, Head of Saab’s business area Kockums.
Originally developed for the Swedish Navy, the electrically propelled system incorporates a fully digital homing system, ensuring ultimate impact. Operational in any conditions SLWT operates equally well in both shallow and blue water, as well as under cold, warm or brackish conditions.
State-of-the-art design ensures optimal performance in difficult hydroacoustic situations, with near-neutral buoyancy enabling advanced manoeuvrability and low speeds. The torpedo also has minimal undershoot to allow launches in shallow waters.
Both a fire-and-forget and wire-guided torpedo, SLWT enables the operator to manually navigate narrow passages and complex terrain when required. If the wire breaks, the torpedo can continue its mission, or abort and swim to the seabed
