Norfolk was the lead ship of the Type 23 Frigates. She was built at Yarrow Shipbuilders in Glasgow and comissioned in 1990. The type 23 had a new vertical launched Seawolf Anti-aircraft Missile System along with Harpoon antiship missiles and a 4.5 inch gun. It also had a smaller compleiment of crew than previous Royal Navy frigates. Norfolk only served for 15 years being a victim of defence cuts in 2005.
