Ship project history


Enlarged Bellerophon with heavier guns and armour, improved hull form and embrasures fore and aft of the battery for end on fire.

Ship protection


There was a narrow waterline strake 229mm-thick part was 22.5m-long, forward and aft from this part the belt was 152mm. Upper and lower sections of the belt had a uniform 152mm thickness from bow to stern. The box 254mm guns battery sides had 203mm lower strake and 152mm upper strakes closed at the ends by 152mm fwd and 127mm aft bulkheads. 229mm guns at each end of the main deck were protected by 152mm armour.

Designed speed was 14kts at 6750hp, boiler pressure was 2.1kgf/cm2. Hercules was ship rigged, sail area was 4600m2 including stunsails, but she was not a good sailer, the best speed under sails was 11kts. She was a good seaboat and a steady gun platform, but was difficult to handle in heavy weather.
