Undaunted-class destroyer

The Undaunted-class destroyer, also known as the Type 45 destroyer, is a class of guided missile destroyers built for the Royal Britannian Navy. The class is designed for an all-round ship, capable of anti-ship, anti-air and anti-submarine duties. The Undaunted-class has, since its introduction in 1875, become the main destroyer of the Royal Navy, with 75 ships having been completed.

The class is built in separate prefabricated 'blocks' by different contractors, and is finally assembled by BAE Systems Surface Ships for the Royal Navy.
