They have a diesel fuel capacity of 200 tons, giving a range of 8,000 nautical miles (15,000 km 9,200 mi) at 8 knots (15 km/h 9.2 mph) and 10,000 nautical miles (19,000 km 12,000 mi) at snorting depth. This gives the vessels a maximum speed of 12 knots (22 km/h 14 mph) on the surface and 20 knots (37 km/h 23 mph) submerged. The submarine is propelled by a 4.028-megawatt (5,402 hp) GEC dual armature electric motor turning a seven-blade fixed pitch propeller. ![]() The batteries have a 90-hour endurance at 3 knots (5.6 km/h 3.5 mph). There are two 120-cell Chloride batteries. They are equipped with two Paxman Valenta 1600 RPS SZ diesel engines, each driving a 1.4- megawatt (1,900 hp) GEC electric alternator. The submarines are powered by a single-shaft diesel-electric system. The class has a reported dive depth of over 650 feet (200 m). The hull is fitted with elastomeric acoustic tiles to reduce the submarine's acoustic signature. The submarines have a single-skinned, teardrop-shaped hull constructed from NQ1 high tensile steel. The submarines had a complement between 44 and 47 with the Royal Navy. ![]() The submarines are 230 feet 7 inches (70.28 m) long overall with a beam of 25 feet (7.6 m) and a draught of 17 feet 8 inches (5.38 m). The design displaces between 2,168 and 2,220 tons surfaced and 2,400–2,455 tons submerged. (VSEL) Type 2400 diesel-electric patrol submarine design was selected. The Vickers Shipbuilding & Engineering Ltd. However, the need for export potential upped the displacement limit to 2,400 tons to allow for flexibility in construction if the need for alternative machinery and systems arose. ![]() Five designs were put forward, with the MoD selecting the 1,960-ton design. The announcement for the new design took place in September 1979. The new submarine class was intended to provide a more cost-effective alternative for training and in coastal defence. In the late 1970s the United Kingdom Ministry of Defence (MoD) proposed a diesel-electric submarine design to replace the Oberon class. These problems have largely been overcome and the subs have achieved full operational capability.ĭesign and development A cross-section of an Upholder-class submarine These submarines initially suffered from serious electrical problems and were beset by mechanical operational incidents that limited their active service and the scope of their deployments. In Canadian service, the submarines are classified as the Victoria class. 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. Their British service life was short, with the vessels being decommissioned in 1994. The boats were originally named the Upholder class, after the most renowned vessel of the former U class. The Upholder/ Victoria-class submarines, also known as the Type 2400 (due to their displacement of 2,400 tonnes), are the class of the diesel-electric submarines built in the United Kingdom in the 1980s to supplement the nuclear submarines in the Submarine Service of the British Royal Navy.
