A nearby memorial plaque remembers those who died during the three air raids in 1940 that targeted the Supermarine works. Reuse of the Supermarine name The name was revived in 1990 by a company in Burslem called Supermarine Aero Engineering Ltd. that hand builds parts for Spitfire planes. Northshore Marine Motor Yachts builds a range of motorboats under the Supermarine name in Itchenor near Chichester, England. The name is also used for Spitfire replicas made by an Australian company in Cisco, Texas. Supermarine aircraft Initially, the company had no system for naming projects with a structured system only coming into use just prior to the company being purchased by Vickers-Armstrongs. The new owners imposed the Vickers' system where once a new project was approved for further work a Type number was allocated. Vickers initially assigned a block of Type numbers from 178 to 190 to Supermarine.
