The Type 23, nicknamed the Duke class since its ships are named after British dukes, is a Royal Navy anti-submarine frigate built by Yarrow and Swan Hunter from the late 1980s. Sixteen were built between 1989 and 2002, and surviving ships carry Sea Ceptor air-defence missiles, a 4.5-inch gun and a Merlin helicopter.
