HMS Sirius (1786) - As HMS Berwick

As HMS Berwick

The newly purchased vessel was fitted out and coppered at Deptford Dockyard between December 1781 and April 1782, for a total sum of £6,152.11s.4d. When completed she carried 10 guns, four 6-pounder long guns, and six 18-pounder carronades. She was commissioned for service under her first commander, Lieutenant Bayntun Prideaux in January 1782, and went out to North America later that year. She spent the last part of the American War of Independence there, transferring to the West Indies in June 1784. Paid off in February 1785 she was initially laid up before being fitted for sea between September and December 1786 for service with the First Fleet. She was nominally rated as a sixth-rate, allowing her to be commanded by a post-captain, though she retained her armament of only 10 guns, and on 12 October 1786 Berwick was renamed Sirius, after the southern star Sirius.
