Tier X Battleship Special

Commonwealth

Irresistible

A battleship with sixteen 234 mm main guns. It could hypothetically have been built in Britain in the late 1940s and subsequently transferred to the Royal Australian Navy. In terms of architecture and hull design, the ship represents a further development of the Vanguard class. The 234 mm guns were considered a promising weapon system for future warships by the Admiralty in the late 1930s.
