Victoria-class submarines were originally named the Upholder class, after the most renowned vessel of the former U class. Their British service life was short, with the vessels being decommissioned in 1994. After an unsuccessful bid to transfer these submarines to the Pakistan Navy in 1993–1994, the Canadian government eventually purchased the submarines and a suite of trainers from the Royal Navy for Canadian Forces Maritime Command (renamed to Royal Canadian Navy in 2011) to replace their decommissioned Oberon-class submarines in 1998.
The class is equipped with six 21-inch (533 mm) torpedo tubes in the bow. In British service, the submarines were supplied with up to 18 Marconi Mk 24 Tigerfish Mod 2 torpedoes; they were also capable of using UGM-84 Sub-Harpoon missiles. They could also be adapted for use as a minelayer. The DCC Action Information Organization and Fire Control System (AIS/FC), developed from the DCA/DCB systems in service at that time aboard Royal Navy nuclear-powered submarines, was based on two Ferranti FM1600E computers with a digital data bus linked to three dual-purpose consoles. Up to 35 targets could be tracked, and automatic guidance could be provided for four torpedoes against four separate targets.
During the refit for Canadian service, the Sub-Harpoon and mine capabilities were removed and the submarines were equipped with the Lockheed Martin Libra-scope Submarine fire-control system (SFCS) to meet the operational requirements of the Canadian Navy. Components from the fire control system of the Oberon-class submarines were installed. This gave the submarines the ability to fire the Gould Mk 48 torpedo. This torpedo, operating at 40 knots (74 km/h), is deployed against targets over a range of 50 kilometers. The torpedo range is 38 kilometers at speeds up to 55 knots (102 km/h). The type uses active and passive homing to approach the designated target. In 2014, the Government of Canada purchased 12 upgrade kits that will allow the submarines to fire the Mk 48 Mod 7AT torpedo.

This detailed video explores the Victoria-class submarine, a crucial asset for the Canadian Navy, originally part of the UK Royal Navy. We examine the specifications and weapons systems, including the Mk 48 torpedo, highlighting its role in naval warfare. This history documentary offers insights into its service life and continued importance as a Canadian submarine.
