Origin

The Type 23 was initially conceived as anti-submarine warfare platform, with a Lynx or EH-101 Merlin helicopter and a towed-array sonar, intended to replace the frigates of the Leander class. They were to hunt and destroy Soviet submarines in the North Atlantic, and it was even proposed initially that they would not mount anti-aircraft missiles. Instead the Sea Wolf missile system was to be carried by the Fort class replenishment ship, one of which was to support typically four Type 23s, providing servicing facilities for the force's helicopters; the Type 23 would have facilities only for rearming and refuelling them. Anti-submarine warfare is a term referring to warfare directed against submarines. ...

Current Development

As a result of lessons learnt from the Falklands War, the design grew in size and complexity to encompass a medium calibre gun for shore bombardment, and Vertical Launch Sea Wolf (VLS) as a defence against sea-skimming anti-ship missiles such as Exocet. With the addition of Harpoon surface-to-surface missiles, the Type 23 had evolved into a complex and balanced warship which introduced a host of new technologies and concepts to the Royal Navy, including: extensive radar signature reduction design measures, automisation to substantially reduce crew size, a CODLAG (Combined Diesel-electric and Gas) propulsion system providing very quiet running for anti-submarine operations along with excellent range, vertical launch missile technology and — after a false start — a fully-distributed combat management system.

COmbined Diesel-eLectric And Gas (CODLAG) is a modification of the combined diesel and gas propulsion system for ships. ...

The Vertical Launch Sea Wolf surface-to-air missile system was designed for and first deployed on the Type 23. Unlike conventional Sea Wolf, the missile is boosted vertically until it clears the ship's super-structure and then turns to fly directly to the target. Consequently, the ship's structure does not cause no-fire zones that would delay or inhibit missile firing in a conventionally launched system.

As a result they have proven to be excellent ships, despite the fact that the highly specialised role for which they were intended disappeared just as the first examples were entering service.

HMS Norfolk (F230) was the first of the class to enter service, commissioned into the Fleet on June 1, 1990 at a cost of £135.449 million^{[citation needed]}. Later vessels cost £60-96 million.
