Spearfish Torpedo

The Spearfish torpedo is the heavyweight torpedo choice of Royal Navy submarines - it weighs nearly two tonnes. It is capable of blasting enemy submarines or ships out of the water.

At full speed, Spearfish can attack at target up to 14 miles away. At low speed, that increases to more than 30 miles. It is guided either by a copper wire – constantly fed data by the submarine which fired it – or closes on to its target using its inbuilt sonar, delivering a 660lb explosive charge. That detonates either when it strikes the hull of an enemy submarine, or via an acoustic proximity fuse underneath the target.

The explosive charge is powerful enough to break the back of an enemy vessel.
