The estimated value of the order is around $15.21m (SEK150m), with an additional option to increase the order quantity.
Deliveries of the new torpedo launchers are expected to take place next year.
The new torpedo tubes ordered for launching lightweight torpedoes will be designated as Tub m/20 in Sweden.
According to Saab, the new torpedo launchers will replace the existing torpedo tubes being used on the Swedish Navy’s corvettes.
Saab Underwater Systems business unit head Niclas Kolmodin said: “The new torpedo tube will enhance and future proof Sweden’s capability for operating lightweight torpedoes from surface ships, thereby helping their anti-submarine capabilities.”
Saab’s new torpedo tubes are designed to meet the future needs of the Swedish Navy. It will provide a larger torpedo payload as well as support easier loading and unloading.
Additionally, the launcher will provide higher availability and allow surveillance of the tube from a naval command and control centre.
The company developed the new Tub m/20 torpedo tube after Finland placed an order for the Saab Lightweight Torpedo (SLWT) for its Pohjanmaa-class multi-role corvettes.
Last year in December, Saab received an order from FMV to provide heavyweight torpedo launcher system for the Royal Swedish Navy.
Headquartered in Sweden, Saab focuses on delivering advanced systems in aeronautics, weapons, command and control, sensors and underwater systems.
Recently, the company handed over Swedish Navy’s Gävle-class corvette HMS Gävle to Fourth Naval Warfare Flotilla following a mid-life upgrade.
