British D Class Submarine
The D-class submarine was the Royal Navy's first class of submarines capable of operating significantly beyond coastal waters. They were also the first boats to be fitted with wireless transmitters. Ten were laid down between 1907 and 1910, though only 8 were completed as D-class boats. The final two hulls were completed as British E-class submarine. Design and description The patrol submarines evolved from the C-class boats. They were designed to be propelled by diesel motors on the surface to avoid the problems with petrol engines experienced with the A class. These boats were designed for foreign service with an endurance of at on the surface and much improved living conditions for a larger crew. D-class boats were fitted with twin screws for greater manoeuvrability and were fitted with saddle tanks. The D class were the first submarines to be equipped with deck guns forward of the conning tower beginning with ''D6''. Also, reserve buoyancy was increased to 20.6%. Arma ...

Vickers Limited
Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellers for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965. Financial problems following the death of the Vickers brothers were resolved in 1927 by separating Metro-Cammell, Metropolitan Carriage Wagon and Finance Company and Metropolitan-Vickers, then merging the remaining bulk of the original business with Armstrong Whitworth to form Vickers-Armstrongs.

The first, ''A1'' (ordered as ''Holland No. 6''), was launched in July 1902, the last, ''A13'', in April 1905. Propulsion All were propelled underwater by battery-powered electric motors and on the surface by shaft-drive Wolseley Motors, Wolseley petrol engines of (''A1''), (''A2-A4'') or (''A5''-''A12''). ''A13'' had an experimental Vickers diesel engine, which proved to be unreliable. Armaments Armament was two British 18 inch torpedo, torpedo tubes with four torpedoes except for ''A1'', which had 1 tube and 3 torpedoes.
