Torpedoes are self-propelled, cigar-shaped underwater missiles that serve as the primary weapon for submarines to engage surface ships and other submarines.12
These weapons allow for underwater attacks through several key mechanisms:
- Propulsion and Guidance: Modern torpedoes are typically powered by battery-operated electric motors. They utilize sophisticated internal systems, such as gyroscopes, to maintain a set course and depth.1
- Targeting: To strike a target, torpedoes use advanced acoustic systems. Active-acoustic torpedoes emit sound signals and home in on the resulting echoes, while passive-acoustic torpedoes track the noise generated by the target vessel.1
- Detonation: Once a torpedo reaches its target, it is designed to explode upon contact with the hull or when it comes into close proximity, triggering an explosive-filled warhead.1
By enabling submarines to launch attacks from beneath the surface, torpedoes have historically been a decisive factor in naval warfare, particularly during the world wars.12
