How did torpedoes evolve from explosive charges mounted on poles into sophisticated underwater weapons capable of finding moving targets?

This naval history documentary explores the major types of torpedoes, how they developed, and the engineering challenges that shaped more than 160 years of underwater warfare.

The story opens with the tragic loss of USS Tang in 1944, then travels back to the American Civil War and Robert Whitehead's early self-propelled torpedo. Discover the evolution from straight-running and pattern-running designs to acoustic homing, wake detection, and wire-guided systems.

We also explore the differences between heavyweight and lightweight torpedoes, electric and oxygen propulsion, supercavitation, manned torpedoes, nuclear torpedoes, and modern anti-torpedo interceptors.

Along the way, we examine historical and modern examples including the Mark 24 Fido, Mark 48, Mark 54, Japanese Type 93, VA-111 Shkval, and Mark 45 ASTOR.

Each design represents a different attempt to solve the same fundamental challenge: moving through the ocean, reaching a target, and functioning reliably under difficult conditions.
