An underwater missile is an explosive weapon designed to be launched from underwater and deliver a devastating blow to a target on or under the surface of the water. It is also commonly referred to as a torpedo. However, other synonyms for underwater missile include depth charge, submersible bomb, subaqueous projectile, aquatic rocket, and submerged weapon. These synonyms can be used interchangeably to describe a weapon that is capable of traveling underwater with the sole purpose of hitting a target with destructive force. The use of these synonyms depends on the specific context and the desired effect in communication.
