The Type 23 frigate or Duke class is a class of frigates built for the United Kingdom's Royal Navy. The ships are named after British Dukes, thus leading to the class being commonly known as the Duke class. The first Type 23, HMS Norfolk, was commissioned in 1989, and the sixteenth, HMS St Albans was commissioned in June 2002. They form the core of the Royal Navy's destroyer and frigate fleet and serve alongside the Type 45 destroyers. They were designed for anti-submarine warfare, but have been used for a range of uses. Nine Type 23 frigates remain in service with the Royal Navy, with three vessels having been sold to the Chilean Navy and four being retired since 2021.
The third HMS Argyll is a Type 23 Duke-class frigate. Commissioned in 1991 and prior to her retirement, Argyll was the oldest serving Type 23 frigate in the Royal Navy. Like all of her class she was named after a British dukedom, in this case that of Argyll. HMS Argyll was laid down in March 1987 by Yarrow Shipbuilders at Glasgow, and launched in 1989 by Lady Wendy Levene, sponsored by the Worshipful Company of Paviors.
The Type 45 destroyer, also known as the D or Daring class, is a class of six guided-missile destroyers built for the United Kingdom's Royal Navy in the early 21st century. The class is primarily designed for anti-aircraft and anti-missile warfare and is built around the PAAMS air-defence system using the SAMPSON Active electronically scanned array (AESA) and the S1850M long-range radars. The first three destroyers were assembled by BAE Systems Surface Fleet Solutions from partially prefabricated "blocks" built at different shipyards; the remaining three were built by BAE Systems Maritime – Naval Ships. The first ship in the Daring class, HMS Daring, was launched on 1 February 2006 and commissioned on 23 July 2009.
HMS St Albans is a Type 23 frigate of the Royal Navy. She is the sixth ship to bear the name and is the sixteenth and final ship in the Duke class of frigates. She is based in Devonport, Plymouth.
Future planning of the Royal Navy's capabilities is set through periodic Defence Reviews carried out by the British Government.
The Type 26 frigate, also known as City-class frigate, is a class of frigates and destroyers being built for the United Kingdom's Royal Navy, with variants also being built for the Australian and Canadian navies. The programme, known as the Global Combat Ship, was launched by the British Ministry of Defence to partially replace the navy's thirteen Type 23 frigates, and for export. Its primary role is to conduct advanced anti-submarine warfare missions while supporting air defence and general purpose operations. The type is the first naval platform shared between Australia, Canada and the United Kingdom since the pre-Second World War Tribal-class destroyer.
The River class is a class of offshore patrol vessels built primarily for the Royal Navy of the United Kingdom. A total of nine were built for the Royal Navy (RN), four Batch 1 and five Batch 2.

She was handed over to the Royal Navy in December 2008, entered her base port of Portsmouth for the first time in January 2009 and was formally commissioned on 23 July 2009. As the lead ship of the first destroyer class built for the Royal Navy since the Type 42 in the 1970s, she has attracted significant media and public attention.
