One from my collection of scratch built warships
Sheffield Class Type 42 Destroyers
The principle role of the Sheffield Class Type 42 destroyers is to provide area air defence for a task force and since their introduction into service they have constituted the fleet's principle anti-air warfare capability. However they also have the secondary roles of confronting surface and anti-submarine targets. A total of sixteen ships were built between 1972 and 1985, although two were tragically lost in the Falklands War.
