Cherokee-class brig-sloop
The Cherokee class was a class of brig-sloops of the Royal Navy, mounting ten guns. Brig-sloops were sloops-of-war with two masts rather than the three masts of ship sloops. Orders for 115 vessels were placed, including five which were cancelled and six for which the orders were replaced by ones for equivalent steam-powered paddle vessels.

In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
