rail gun

A large type of cannon that uses 2 or more rails (hence the name) that are charged with electromagnetic energy. They electromagnets propel a projectile at high speeds over great distances. These weapons do get very hot after use and therefore require great cooling power.

The US Navy is currrently working on a project to equip a new type of Destroyer with rail guns.
