Project history: Although the Type 22 was recognised as a highly efficient ASW platform, alarm at its high cost led to a call for a cheaper frigate, relying on the Type 2031Z towed array sonar rather than the big Type 2050 and Lynx helicopters. Out of this has emerged the Type 23, expanded to include a bow-mounted sonar, a large ASW helicopter and more general-purpose qualities. Although Falklands experience resulted in improved fire precautions and damage control, the decision to incorporate a double-headed Sea Wolf SAM system predated that conflict. By the time the design was finalized BAE's vertically launched version was nearly ready for trials, and it was selected in place of the earlier lightweight version of GWS25.
The design is optimized for towed array operations, so silencing of machinery was a top priority. Finally a unique combined diesel electric and gas turbine (CODLAG) was chosen, using Spey gas turbines for main drive, and switching to a diesel-electric drive for slow but silent running when using the towed array. The advantage of CODLAG is the elimination of gearbox noise, and the generators are positioned above the waterline to reduce radiated noise.
The opportunity was taken to incorporate ' stealth' features to enhance survivability in surface warfare. This takes the form of a flared hull and the elimination of right angles and radar-reflecting corners in the superstructure, etc. It is claimed that the Type 23 is 'invisible' to the seekers of the current range of anti-ship missiles, and it also claimed to be the quietest ASW ship in the world.
