Bellerophon class battleship
The
Bellerophon class consisted of three
battleships built in 1906 and 1907 for the
Royal Navy.The three ships of the
Bellerophon class (and the subsequent three of the
St Vincent class ) were near-repeats of
HMS Dreadnought. The Bellerophon class was extremely visually similar to the previous
Dreadnought class battleships, with the exception of a second tripod mast. In fact the lead ship ,
HMS Bellerophon, was laid down on the same day of
HMS Dreadnought's final completion, which was also built at
Portsmouth Dockyard.
The
Bellerophon's continued the universal trend of greater displacement and cost. They did address some of the flaws of
Dreadnought. Changes to the hull gave a more complete internal protection and allowed the larger ships to make the same speed with the same powerplant. While
Dreadnought had
bulkheads that protected only the
magazines, the
Bellerophon had complete bulkheads running longitudinally through the ship. The 12-pounder guns that had been added to
Dreadnought for protection from
torpedo boats were recognised as being insufficient and their
secondary armament was made up of 4-inch guns. The foremast which on
Dreadnought was behind the fore funnel so that it could be used for the boat crane was sited ahead of the funnel moving the lookouts stationed on the observation platform out of the smoke plume. A mainmast added ahead of the aft funnel was still affected by the plume of the fore funnel and was not considered a success.These changes did require some compromises in the design resulting in thinner armor, reducing the belt armor from 11 to 10 inches, and a reduced
coal bunkerage, which limited the steaming endurance.
