Ship project history


New 101-gun ships. Surveyor's Department design of 1857. Longer and broader version of Conqureror class, with the same armament. Both re-classed as 99-gun in 1861, to 85-gun in 1862 and to 81-gun in 1863. In 1867 there was a design proposed by Reed to fit Duncan as a breastwork turret ironclad, but this was cancelled for financial reasons. Wooden hull.

One more ship of class Robust was ordered in 1857 but in 1858 re-ordered as 90-gun ship.
