HMSA10 was anA-classsubmarine built for theRoyal Navy in the first decade of the 20th century. After surviving World War I, she was sold forscrap in 1919.

A10 was a member of thefirst British class of submarines, although slightly larger, faster and more heavily armed than thelead ship,HMS A1. The submarine had a length of 105 feet 1 inch (32.0 m)overall, abeam of 12 feet 9 inches (3.9 m) and a meandraft of 10 feet 8 inches (3.3 m). Theydisplaced 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 9ratings.^[1]

For surface running, the boats were powered by a single 16-cylinder 600-brake-horsepower (447 kW)Wolseleypetrol engine that drove onepropeller shaft. When submerged the propeller was driven by a 150-horsepower (112 kW)electric motor. They could reach 11knots (20 km/h; 13 mph) on the surface and 6 knots (11 km/h; 6.9 mph) underwater.^[1] On the surface,A10 had a range of 500nautical miles (930 km; 580 mi) at 10 knots (19 km/h; 12 mph); submerged the boat had a range of 30nautical miles (56 km; 35 mi) at 5 knots (9.3 km/h; 5.8 mph).^[2]

The boats were armed with two18-inch (45 cm)torpedo tubes in the bow. They could carry a pair of reload torpedoes, but generally did not as their weight had to be compensated for by an equivalent weight of fuel.^[3]

A10 was ordered as part of the 1903–04 Naval Programme fromVickers.^[4] She was laid down at theirshipyard inBarrow-in-Furness in 1903,launched on 8 February 1905 and completed on 3 June 1905.^[2] She collided with thebattleshipHMS Empress of India inPlymouth Sound on 30 April 1906.^[5]

A10 was sold forscrap to the Ardrossan Drydock Company ofArdrossan,Scotland, on 1 April 1919 .
