The Type 42 or Sheffield class, are guided missile destroyers of the British Royal Navy. The Sheffield destroyer class was designed to provide fleet area air-defence. The Type 42 destroyer was built to fill the gap left by the cancellation of the large Type 82 destroyer. It was intended to fulfil the same role, with similar systems yet on a smaller and more cost effective hull. The ships are primarily carriers for the GWS-30 Sea Dart surface-to-air missile system. In total fourteen vessels were constructed in three batches, eight of which remain in service. The ships are all scheduled to be out of service by 2014. In addition, two ships were also built for the Armada Republica Argentinato; they were built to the same specifications as the Batch 1 vessels but are also armed with the Exocet SSM and no CIWS.
