DESTROYER

a medium-sized warship built around steam or gas turbine propulsion and carrying a range of weaponry. Vessels of this type have varied considerably across the 20th century, being originally designed as specialised fast craft with a heavy torpedo armament. In recent years, the term has come to denote a generalised warship designed around a long-range (area defence) anti-aircraft missile system, and carrying a helicopter for anti-submarine operations.Warships of this type have traditionally tended to operate as part of larger formations rather than independently, being similar to Frigates in this respect.
