Like the perimeter action ships, corvettes were patrol combatants (Ships of the Star Fleet) designed for high-warp military engagements. Unlike those ships, corvettes were designed for longer-duration missions, had slightly larger crew sizes and had a higher deadweight tonnage (though less than that of destroyers).
During the 25th century, the Orion Syndicate also built and fielded its own corvettes to serve as light raiders. While fast and highly maneuverable, they were generally not considered a threat to larger assault or exploration cruisers. (Star Trek Online: Valkyries)
