The Roebuck-class ship was a class of twenty 44-gun sailing two-decker warships of the Royal Navy. The class carried two complete decks of guns, a lower battery of 18-pounders and an upper battery of 9-pounders. This battery enabled the vessel to deliver a broadside of 285 pounds. Most were constructed for service during the American Revolutionary War but continued to serve thereafter. By 1793 five were still on the active list. Ten were hospital ships, troopships or storeships. As troopships or storeships they had the guns on their lower deck removed. Many of the vessels in the class survived to take part in the Napoleonic Wars. In all, maritime incidents claimed five ships in the class and war claimed three.

HMS Roebuck was a fifth-rate ship of the Royal Navy which served in the American and French Revolutionary Wars. Designed in 1769 by Sir Thomas Slade to operate in the shallower waters of North America, she joined Lord Howe's squadron towards the end of 1775 and took part in operations against New York the following year. She engaged the American gun batteries at Red Hook during the Battle of Long Island in August 1776, and forced a passage up the Hudson River in October. On 25 August 1777, Roebuck escorted troopships to Turkey Point, Maryland, where an army was landed for an assault on Philadelphia. She was again called upon to accompany troopships in December 1779, this time for an attack on Charleston. When the ships-of-the-line, which were too large to enter the harbour, were sent back to New York, Admiral Marriot Arbuthnot made Roebuck his flagship. She was, therefore, at the front of the attack, leading the British squadron across the shoal to engage Fort Moultrie and the American ships beyond.
