HMS Swiftsure was a 70-gun third-rate ship of the line of the Royal Navy, built by Sir Anthony Deane at Harwich, and launched in 1673.

She saw action during the unsuccessful Battle of Toulon and was present during the great naval disaster off the Isles of Scilly when Shovell and four of his ships (Association, Firebrand, Romney and Eagle) were lost, claiming the lives of nearly 2,000[5] sailors.

Swiftsure suffered little to no damage and finally managed to reach Portsmouth.

She underwent a second rebuild at Woolwich Dockyard, relaunching on 20 November 1718 as a 70-gun third rate of the 1706 Establishment.

[3] On 25 February 1740 Revenge was ordered to be taken to pieces at Deptford, and to be rebuilt as a 70-gun third rate to the 1733 proposals of the 1719 Establishment.
