HMS Bellerophon Bellerophon class.  Visually similar to Dreadnought but with a second tripod mast.  The position of the tripod masts was far from ideal and if the wind was in the right direction they could be interfered with by smoke and heat form the funnels.  The positioning was influenced by the peacetime requirement for easy boat handling.

Comments:
Similar to the preceding Dreadnought class.  The main armament was the same but there was an increase in the secondary armament in response to the increasing size of torpedo boats.  They also had improved underwater protection with continuous anti-torpedo bulkheads running from the forward of the  forward magazine and covering to the end of the rear magazine.  Crew 680.

HMS Temeraire.  Some of the secondary anti-torpedo boat guns can be seen on the turret roofs.  It was not expected at the time of construction that these guns would be manned during a fleet action as it was felt that no Admiral would order such an attack during an action as it would interfere with the main action, the torpedo boats being used either before or after the main action.
