The Type 42 or Sheffield class, was a class of fourteen light guided missile destroyers that served in the Royal Navy. A further two ships of this class were built for and served with the Argentine Navy.

The first ship of the class was ordered in 1968 and launched in 1971. Two of the class (Sheffield and Coventry) were sunk in action during the Falklands War of 1982. The Royal Navy used this class of destroyer for 38 years between 1975 and 2013.

No ships of this class remain active in the Royal Navy and just one remains in the Argentine Navy. The Royal Navy has replaced them with Type 45 destroyers.

The class was designed in the late 1960s to provide fleet area air-defence. In total fourteen vessels were constructed in three batches. In addition to the Royal Navy ships, two more ships were built to the same specifications as the Batch 1 vessels for the Argentine Navy. Hércules was built in the UK and Santísima Trinidad in the AFNE Rio Santiago shipyard in Buenos Aires.

Sheffield and Coventry were lost in the Falklands War to enemy action. (This was the first conflict when surface warships of the same design have been on opposite sides since World War II, when four Flower-class corvettes built for France in 1939 were taken over by the Kriegsmarine in 1940.) The final ship of the class (Edinburgh) decommissioned on 6 June 2013. One Argentine Navy ship (Hércules) remains in service, the other vessel (Santísima Trinidad) sank whilst alongside in Puerto Belgrano Naval Base in early 2013.

When the Type 82 air-defence destroyers were cancelled along with the proposed CVA-01 carrier by the Labour Government of 1966, the Type 42 was proposed as a lighter and cheaper design with similar capabilities to the Type 82. The class is fitted with the GWS30 Sea Dart surface-to-air missile first deployed on the sole Type 82 destroyer, Bristol. The Type 42s were also given a flight deck and hangar to operate an anti-submarine warfare helicopter, greatly increasing their utility compared to the Type 82, which was fitted with a flight deck but no organic aviation facilities.
