Corvette

A corvette is a small, maneuverable, lightly armed warship, originally smaller than a frigate and larger than a coastal patrol craft or fast attack craft , although many recent designs resemble frigates in size and role...

Sloop-of-war

In the 18th and most of the 19th centuries, a sloop-of-war was a warship with a single gun deck that carried up to eighteen guns. As the rating system covered all vessels with 20 guns and above, this meant that the term sloop-of-war actually encompassed all the unrated combat vessels including the...

. The term 'corvette' was not introduced into the Royal Navy until the 1830s, and at that time its use replaced both the larger sloops and also what had previously been categorised officially as 'post ships', i.e. ships of 20, 22 or 24 guns (vessels of 28 guns and above were classed as 'frigates' until 1817, thereafter ships of up to 32 guns were also counted as sixth rates) which were so-called because they were the lowest grade of warship which could be commanded by a 'post captain'; as such, they formed the lower portion of the sixth rate.

In 1887, both frigates and corvettes were merged into a new category of 'cruiser'. In 1937, escort sloops were officially re-rated as escort vessels and patrol sloops as patrol vessels, although the traditional term continued in use. In 1948 surviving sloops and corvettes were redesignated as frigate

Frigate

A frigate is any of several types of warship, the term having been used for ships of various sizes and roles over the last few centuries.In the 17th century, the term was used for any warship built for speed and maneuverability, the description often used being "frigate-built"...
