HMS Diamond is the third ship of the Type 45 or Daring-class air-defence guided missile destroyers built for the Royal Navy. She was launched in 2007, and completed her contractor's sea trials and arrived at her base port in 2010. Diamond formally entered service in 2011.

It is equipped with a SAMPSON active electronically scanned array multi-function radar system that allows the Diamond to track 2,000 threats from over 250 miles away, a Sea Viper missile system that can launch eight missiles in under 10 seconds and can guide up to 16 missiles simultaneously, a Wildcat HMA2 helicopter with Martlet air-to-surface missiles, and a 4.5-inch Mark 8 naval gun.

In December 2023, Diamond shot down a suspected attack drone launched from a Houthi-controlled area of Yemen, with a Sea Viper missile, in what the UK Ministry of Defence said was the first time in decades that the Royal Navy had shot an aerial target in anger. On 10 January 2024, the Houthis carried out a more daring attack on US and UK ships. This was a missile barrage, and all the missiles were shot down by Diamond, USS Dwight D. Eisenhower, and other naval vessels.^[35][36]
