The fourth Type 45 joined the Royal Navy

She joins her sister ships HMS "Daring", HMS "Dauntless" and HMS "Diamond". As Class Output Manager for the fleet, BAE Systems also provides in-service support to the Type 45 destroyers, with the company’s engineers coordinating all aspects of repair, maintenance and support to improve ship availability and reduce through life support costs.
 
The Type 45s will provide the backbone of the UK’s naval air defences for the next 30 years and beyond. The destroyers are said to be capable of carrying out a wide range of operations, including anti-piracy and anti-smuggling activities, disaster relief work and surveillance operations as well as high intensity war fighting.
