The Black Prince-class ships of the line were a class of four 74-gun third rates built for the Royal Navy in the closing years of the Napoleonic War. The draught for this class of ship was essentially a reduced version of the captured Danish ship Christian VII.

The Wellesley, while ordered to be built to this design and always officially so classified, was actually built to the design of and used the moulds of the Cornwallis, a Vengeur/Armada class ship previously built at Bombay; this was because the set of plans sent from the Navy Board and intended for the construction of the Wellesley were lost en route to India when the ship carrying them was captured and burnt by the Americans.

The Hawke was converted to screw propulsion in the 1850s when adapted as a 60-gun "blockship".
