The Fly class were built as a 16-gun class of brig-sloops for the Royal Navy, although an extra two carronades were added soon after completion. The class was designed by one of the Surveyors of the Navy - Sir John Henslow - and approved in 1805. Five vessels to this design were ordered in January 1805; two more were ordered in the summer, although this final pair were planked with hulls of pitch pine ("fir") rather than the normal oak used in the first five.
