The previous attempts had been the steam powered <a href="/wiki/British_K-class_submarine" title="British K-class submarine">K-class submarines</a> and the large 12-inch (305 mm) gunned <a href="/wiki/British_M-class_submarine" title="British M-class submarine">M-class submarines</a>. The M class were K-class <a href="/wiki/Hull_(watercraft)" title="Hull (watercraft)">hulls</a> re-engined with diesels and modified to take a single 12 in (305 mm) naval gun directly forward of the <a href="/wiki/Conning_tower" title="Conning tower">conning tower</a>. </p><p>A design was drawn up in the late 1920s and three vessels were built by <a href="/wiki/Vickers" title="Vickers">Vickers</a> in Barrow: <i>Thames</i> in 1932, and <i>Severn</i> and <i>Clyde</i> in 1935. The latter two were a little larger than <i>Thames</i>. Initially 20 were planned, but changes in thinking and cost-cuts limited the building to just the three. </p><p>The design compromised on diving depth to keep weight down and speed up. They had a safe diving depth of some 300 feet (90 m) compared to the <a href="/wiki/Odin-class_submarine" title="Odin-class submarine"><i>Odin</i> class</a> before them which had managed 500 feet (150 m). They were powered by two <a href="/wiki/Diesel_engine" title="Diesel engine">diesel engines</a> delivering 8,000 <a href="/wiki/Horsepower#Brake_horsepower" title="Horsepower">bhp</a> (6,000 kW). Two <a href="/wiki/Ricardo_plc" class="mw-redirect" title="Ricardo plc">Ricardo</a> engines drove generators that supercharged the diesels up to 10,000 bhp (7,500 kW). This gave them a surface speed of 22 knots (41 km/h). A rather unfortunate fault with the River-class was a tendency for engine trouble after several long journeys. Another alarming fault, although this was confined to <i>Clyde</i> was the hydroplanes failing, causing the submarine to bottom. This would put a great stress on the hull of the submarine, as it was of riveted construction, rather than the welded construction of other British submarines. </p> <div class="mw-heading mw-heading2"><h2 id="Operational_history">Operational history</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=River-class_submarine&action=edit&section=2" title="Edit section: Operational history"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>During the Second World War, they initially operated in the <a href="/wiki/North_Sea" title="North Sea">North Sea</a> and <a href="/wiki/Mediterranean" class="mw-redirect" title="Mediterranean">Mediterranean</a>, then moved to the Far East in the latter stages. </p><p><i>Clyde</i> and <i>Severn</i> set sail from Gibraltar heading to take up station in Freetown on 31 August 1939, just four days before the outbreak of hostilities.

Convoy duty was not something that was alien to <i>Severn</i> and <i>Clyde</i>, as they would carry out this duty on a regular basis due to their long range. <i>Clyde</i> and <i>Severn</i> would both go through an extensive refit in the USA </p><p><i>Severn</i> had the most colourful service out of all three. It would be used in the aftermath of the <a href="/wiki/Battle_of_the_River_Plate" title="Battle of the River Plate">Battle of the River Plate</a> to hunt for German Surface Raiders and their support ships. April 5, 1940 would see Severn join the northbound convoy FN139. It would also be put on standby for potential involvement in the hunt for the Bismarck, but the Bismarck was sunk before the Severn was called into action. It would be used for part of <a href="/wiki/Operation_Hawthorn" title="Operation Hawthorn">Operation Hawthorn</a> during June - July 1943. <i>Severn</i> and <i>Clyde</i>, whether it was by choice or accident, would often be stationed together. <i>Severn</i> and <i>Clyde</i> were in service in the Far East (operating out of <a href="/wiki/Trincomalee" title="Trincomalee">Trincomalee</a>) when they were taken out of service - <i>Severn</i> in December 1944 and <i>Clyde</i> in July 1945.
