Duke of Kent was a proposed 170-gun line of battle ship allegedly designed by future Surveyor of the Navy Joseph Tucker in 1809.

[5] The vessel would have mounted fifty more guns than the contemporary Caledonia class, which were then the Royal Navy's most heavily armed ships.

[3] The model, described as a "beautiful work of art", was donated to the Greenwich Hospital by Tucker's widow in 1852 and was originally displayed in its Painted Hall.

[4] Naval historian Geoffrey Swinford Laird Clowes cast doubt on the claimed 1809 date for the design in his 1932 book Sailing Ships: Their History and Development.

He noted that the inscription on the drawings refers to Sir William Symonds, Surveyor of the Navy from 1832 to 1847 and to two of his ships: Queen laid down in 1833 and Royal Albert of 1844.
