The Type 23 frigate is a frigate serving in the British Royal Navy. All ships of this class are named after the British Duke, so this class of ships is also called the Duke class. Among the current ships of the Royal Navy, the largest number of surface warships is undoubtedly the 16 Type 23 frigates, and the last “St Albans” was officially commissioned in November 2001. The Type 23 frigate is equipped with very strong weapons, with anti-submarine, air defense, anti-ship, and anti-shore three-dimensional offensive and defensive capabilities, especially its anti-submarine capabilities. The Duke-class frigate is the world’s first frigate equipped with a vertical missile launcher.
