HMS Bulldog is a Type 31 frigate of the Royal Navy and the eighth vessel named Bulldog.[7] The name was selected to represent key themes that represent the future plans of the Royal Navy and Royal Marines.
Bulldog, named after the Second World War B-class destroyer HMS Bulldog (H91), which escorted convoys in the Atlantic, was chosen to represent operations in the North Atlantic. Bulldog captured a German Enigma machine and associated codebooks that were on board U-boat U-110. Its capture enabled British intelligence to decipher German naval messages.[8] The plan for the Type 31 project envisages all five units of the class being in service by February 2030.[9]
The first steel for HMS Bulldog was cut on 24 February 2026.[10]
