Frigate vs. Corvette: What's the Difference?

By Aimie Carlson & Janet White || Updated on March 4, 2024
A frigate is a type of warship that is larger, often designed for open ocean warfare and performing a variety of missions, whereas a corvette is smaller, typically used for coastal defense and patrol duties.

Key Differences

Frigates and corvettes are both classes of warships used by navies around the world, each serving distinct roles based on their size, armament, and capabilities. Frigates are larger vessels that operate in open seas, equipped to engage in warfare against submarines, aircraft, and surface ships. Corvettes, on the other hand, are the smallest class of warships considered to be rated vessels. They are primarily used for coastal patrol and defense, anti-submarine warfare, and sometimes mine-sweeping operations.
The decision to deploy frigates or corvettes depends on the mission's specific requirements. Frigates are better suited for blue-water (open ocean) operations where endurance, versatility, and the ability to project power are necessary. In contrast, corvettes are more often utilized in green-water (coastal) and brown-water (riverine or near-shore) operations, where their capabilities are well-suited to the environment and mission scope.
In terms of hierarchy and naval strategy, frigates are typically part of larger task forces or flotillas, serving as the principal combatants in many navies, while corvettes operate either independently or in support of larger vessels, providing localized patrol and escort services. The distinction between frigates and corvettes is not just a matter of size but reflects their intended tactical and strategic use in modern naval operations.

A fast, lightly armed warship, smaller than a destroyer, often armed for antisubmarine operations.


(Obsolete) A fast, light vessel, such as a sailboat.


An obsolete sailing warship, smaller than a frigate, usually armed with one tier of guns.


(nautical) Any of several types of warship:


A flush-decked warship of the 17th-18th centuries having a single tier of guns; it ranked next below a frigate; – called in the United States navy a sloop of war.


(historical) A sailing warship (of any size) built for speed and maneuverability; typically without raised upperworks, having a flush forecastle and tumblehome sides.


(nautical) In a modern navy, a lightly armed and armoured blue water warship, smaller than a frigate, capable of transoceanic duty.


(historical) A sailing warship with a single continuous gun deck, typically used for patrolling and blockading duties, but not considered large enough for the line of battle.


A highly maneuverable escort warship; smaller than a destroyer


(historical) A warship combining sail and steam propulsion, typically of ironclad timber construction, supplementing and superseding sailing ships of the line at the beginning of the development of the ironclad battleship.


(historical) A escort warship, smaller than a destroyer, introduced in World War 2 as an anti-submarine vessel.


A modern type of warship, equivalent in size or smaller than a destroyer, often focused on anti-submarine warfare, but sometimes general purpose.


(fictional) A warship or space warship, inspired by one of the many historic varieties of frigate.


A frigatebird (Fregata spp.).


Originally, a vessel of the Mediterranean propelled by sails and by oars. The French, about 1650, transferred the name to larger vessels, and by 1750 it had been appropriated for a class of war vessels intermediate between corvettes and ships of the line. Frigates, from about 1750 to 1850, had one full battery deck and, often, a spar deck with a lighter battery. They carried sometimes as many as fifty guns. After the application of steam to navigation steam frigates of largely increased size and power were built, and formed the main part of the navies of the world till about 1870, when the introduction of ironclads superseded them.


Any small vessel on the water.


A medium size square-rigged warship of the 18th and 19th centuries


A United States warship larger than a destroyer and smaller than a cruiser


Capable of long-duration missions.
Frigates often undertake months-long deployments without needing to resupply.
