Thermal torpedoes can have a much longer-range at higher-speeds than their electric counterparts. Liquid fuel stores more energy and can be burned more efficiently in modern gas turbines engines, giving these lethal weapons the engagement range and speed required to hit any target from outside detection range.

How powerful is a torpedo?

The Torpedo 62 has a launch weight of 1,450kg and can carry high explosive warhead. The torpedo operates at depths of 500m and is guided by active/passive homing system. The torpedo is propelled by an advanced pump jet engine and can engage targets within the range of over 40km, at a maximum speed of 40kt.

Why is torpedo so important?

Because of improved submarine strength and speed, torpedoes had to be given improved warheads and better motors. During the Cold War torpedoes were an important asset with the advent of nuclear-powered submarines, which did not have to surface often, particularly those carrying strategic nuclear missiles.
