The Type 42 Destroyer is a class of guided missile destroyers that were primarily used by the Royal Navy of the United Kingdom. Designed in the 1970s, these ships were built for air defense and anti-submarine warfare. They feature a sleek hull design and are equipped with advanced radar and missile systems, making them effective in naval combat. A total of 14 ships were constructed, with the first entering service in 1978. The Type 42 destroyers played a significant role during the Falklands War and were gradually replaced by the more advanced Type 45 Destroyers in the 2000s.
