The Submarine is designed to travel underwater allowing it to operate

clandestinely against other naval units. Its main armament consists of

torpedoes which are deadly against all other types of vessel, be they

Carrier, Battleship, Naval Transport or another Submarine. However, the

Submarine can be handicapped by a short range and new technologies to

improve them can be expensive.

​

-   Submarines cannot shore bombard. Instead, they have a higher convoy

    attack value (other ships use their sea attack).

-   Please read the [Submarine

    Guide](/wiki/Submarine_Guide "Submarine Guide") for a detailed

    analysis of this unit in the different versions of HoI.
