Key Features of British Submarines
Key Features of British Submarines
The main armament of the newcomers is represented exclusively by acoustic torpedoes. There is a large number of torpedoes per salvo, and they have a fast reload, but low damage. Also, Undine and Sturdy have a 76mm secondary battery gun, and Thrasher is armed with a 102mm main battery gun that can be directly controlled by the player. All of these guns fire SAP shells.
British submarines have a large dive capacity, but low manoeuvrability. They will be able to stay underwater for long periods of time, but it will be difficult to quickly change direction or retreat if detected. Attacks should also be executed with extreme caution, as the new submarines have a small HP pool, even compared to other nations' submarines.
They perform best in close- and medium-range combat. It will be difficult for British subs to do effective damage from a very close range: acoustic torpedoes have low damage, and the submarines themselves have a low HP pool. Therefore, you should play British submarines more carefully, considering the torpedo range and large dive capacity.
