The Type 74 TORIN (Torpilă Încapsulat) is the Imperial Sea Legion's primary anti-submarine naval mine. This deep-water mine is laid by ship, aircraft or submarine, and is anchored to the ocean floor. When its sonar detects a hostile submarine, the TORIN launches a Type 55 torpedo.
The TORIN is the principle anti-submarine mine mostly due to having enough computer power to detect the difference in acoustic signature between ships and submarines. When an enemy submarine passes close by, the passive sonar detects it and releases the torpedo, which tracks the sound until it contacts the submarine hull and explodes, as well as the Type 55 torpedo offering limited autonomous terming homing abilities.
