HMS A11 was an {{sclass2-|A|submarine (1903)|0}} submarine built for the Royal Navy in the first decade of the 20th century. After surviving World War I, she was sold for scrap in 1920. Design and descriptionA11 was a member of the first British class of submarines, although slightly larger, faster and more heavily armed than the lead ship, {{HMS|A1}}. The submarine had a length of {{convert|105|ft|1|in|m|1}} overall, a beam of {{convert|12|ft|9|in|m|1}} and a mean draft of {{convert|10|ft|8|in|m|1}}. They displaced {{convert|190|LT|t}} on the surface and {{convert|206|LT|t}} submerged. The A-class submarines had a crew of 2 officers and 11 ratings.[1]For surface running, the boats were powered by a single 16-cylinder {{convert|600|bhp|lk=in|0|adj=on}} Wolseley petrol engine that drove one propeller shaft. When submerged the propeller was driven by a {{convert|150|hp|0|adj=on}} electric motor. They could reach {{convert|11|kn|lk=in}} on the surface and {{convert|6|kn}} underwater.[1] On the surface, A11 had a range of {{convert|500|nmi|lk=in}} at {{convert|10|kn}}; submerged the boat had a range of {{convert|30|nmi|lk=in}} at {{convert|5|kn}}.[2] The boats were armed with two 18-inch (45 cm) torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as doing so that they had to compensate for their weight by removing an equal weight of fuel.[3] Construction and careerA11 was ordered as part of the 1903–04 Naval Programme from Vickers.[4] She was laid down at their shipyard in Barrow-in-Furness in 1903, launched on 8 March 1905 and completed on 11 July 1905.[2]On 7 September 1910 A11 collided with a barge when leaving Portsmouth Harbour. The barge was sunk, although her two crew were rescued, and A11{{'}}s bow was slightly damaged.[5] Notes1. ^1 Gardiner & Gray, p. 86 2. ^1 Akermann, p. 120 3. ^Harrison, Chapter 27 4. ^Harrison, Chapter 3 5. ^{{cite magazine|title=Naval Matters—Past and Prospective: Portsmouth Dockyard |journal=The Marine Engineer and Naval Architect |volume=33|date=October 1910|p=98}} References
