(26 km/h; 16 mph) versus a surfaced speed of 9 knots (17 km/h; 10 mph). They were well-streamlined, having no external ballast tanks, casing, or <a href="/wiki/Deck_(ship)" title="Deck (ship)">deck</a> gun, and a <a href="/wiki/Streamliner" title="Streamliner">streamlined</a> <a href="/wiki/Spindle_(textiles)" title="Spindle (textiles)">spindle</a>-shaped <a href="/wiki/Hull_(watercraft)" title="Hull (watercraft)">hull</a> of circular cross-section<sup id="cite_ref-Fitzsimons_2-0" class="reference"><a href="#cite_note-Fitzsimons-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> (not reproduced until the American <a href="/wiki/USS_Albacore_(AGSS-569)" title="USS Albacore (AGSS-569)">USS <i>Albacore</i></a>) which tapered sharply towards the stern and allowed only for a single <a href="/wiki/Propeller" title="Propeller">screw</a>. The bulbous bow contained five sensitive <a href="/wiki/Sonar" title="Sonar">hydrophones</a> and the lightened <a href="/wiki/Conning_tower" title="Conning tower">conning tower</a> was also well-streamlined. </p><p>Thirty-five per cent of the space inside the pressure hull was occupied by machinery. A single 8-cylinder 480 hp (360 kW) diesel engine was installed for surface propulsion, while high underwater speed was given by two large electric motors arranged one behind the other to drive the single propeller shaft, and powered by a 200-cell battery of the same type fitted to <a href="/wiki/British_J-class_submarine" class="mw-redirect" title="British J-class submarine">J-class</a> submarines. The large battery was, however, sufficient for only about an hour at full power. In addition, the engine took a full day to charge the batteries, using half its power. Charging was therefore undertaken in harbour, using a supply of electricity from the shore or from special battery charging vessels.<sup id="cite_ref-akermann_3-0" class="reference"><a href="#cite_note-akermann-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>Despite being designed for maximum underwater performance, the R-class submarines were extremely difficult to control submerged, especially at high speeds.
