HMS Hood (51)
 HMS Hood (pennant number 51) was the last battlecruiser built for the Royal Navy. Commissioned in 1920 she was named after the 18th-century Admiral Samuel Hood. One of four Admiral-class battlecruisers ordered in mid-1916 Hood had serious design limitations though her design was drastically revised after the Battle of Jutland and improved while she was under construction. For this reason she was the only ship of her class to be completed.
