The Sussex was a fourth-rate frigate, built for the navy of the Commonwealth of England at one of the national Dockyards, and launched in late 1652.

Her place of building is uncertain, with certain sources recording this as Portsmouth (by John Tippetts), others as Deptford and still others as Woolwich (by Christopher Pett).

A standard practice at this time was to build the hull in one location and masts and superstucture could be at a separate dock, and the fitting of equipment (cannon etc) at a third location.

She was commissioned under Captain Roger Cuttance, and fitted out on the Thames.
