HMS Sultan was a 74-gun third rate ship of the line of the Royal Navy, launched on 23 December 1775 at Harwich. Built to take part in the American Revolutionary War, her departure was delayed due to a shortage of crew and it was 9 June 1778 before she finally sailed as part of a squadron led by Rear-Admiral John Byron. In September she was with Richard Howe's fleet, blockading the French in Boston and in 1779, transferred to the West Indies, where she took part in the Battle of Grenada that July. Almost a year later, on 20 June 1780, she was involved in a short action off the coast of the Dominican Republic with a superior French force.

The Battle of Negapatam was the third in a series of battles fought between a British fleet, under Vice-Admiral Sir Edward Hughes, and a French fleet, under the Bailli de Suffren, off the coast of India during the American Revolutionary War. The battle was fought on 6 July 1782. Though the battle was indecisive, Suffren was stopped in his goal by Hughes and withdrew to Cuddalore, while the British remained in control of Negapatam.
