HMS A3 was an Template:Sclass2- submarine built for the Royal Navy in the first decade of the 20th century.
Design and description
A3 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 105 feet 1 inch (32.0 m) overall, a beam of 12 feet 9 inches (3.9 m) and a mean draft of 10 feet 8 inches (3.3 m). They displaced 190 long tons (190 t) on the surface and 206 long tons (209 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 450-brake-horsepower (336 kW) Wolseley petrol engine that drove one propeller shaft. When submerged the propeller was driven by a 150-horsepower (112 kW) electric motor. They could reach 10 knots (19 km/h; 12 mph) on the surface and 7 knots (13 km/h; 8.1 mph) underwater. On the surface, A3 had a range of 320 nautical miles (590 km; 370 mi) at 10 knots (19 km/h; 12 mph);[1] the boat had a range of 30 nautical miles (56 km; 35 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged.[2][3]
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 an equivalent weight of fuel.
Construction and career
A3 was built at Vickers, Barrow-in-Furness and was commissioned on 13 July 1904. She primarily served as a coastal defense and training submarine in her over seven years of service. On 2 February 1912, A3, along with several other submarines dispatched from the port of Gosport, conducted training exercises on target ships in the Solent.[4] Whilst attacking the depot ship HMS Hazard, the A3 accidentally collided with its target. Its rudder and propeller were both disabled, and the submarine sank with all hands lost.[4] The submarine was risen in March and was sunk as a gunnery target by shells from the HMS St. Vincent on 15 May 1912.[5] In July 2016 the wreck of A3 was officially designated as a protected site.[6]
