Corvette vs. Frigate — What's the Difference?
By Tayyaba Rehman — Updated on November 3, 2023
A corvette is a small, maneuverable, lightly armed warship, while a frigate is a medium-sized warship with a mix of weapons for anti-submarine, air, and surface warfare.

Key Differences
Corvettes and frigates are both types of warships, but they differ in size, armament, and role. A corvette is generally smaller than a frigate, designed for coastal defense and patrol missions. Frigates, meanwhile, are larger vessels capable of blue-water operations, including anti-submarine warfare and escort duties.
The corvette is traditionally the smallest class of vessel considered to be a rated warship, while the frigate is recognized for its speed and endurance on the high seas. Corvettes are often utilized in littoral zones, close to shore, and in convoy escort roles, whereas frigates undertake broader range missions, including solo and fleet deployments.
Armament is another distinguishing feature; corvettes carry lighter armaments compared to frigates, which are equipped with more extensive weapons systems, including surface-to-air missiles, anti-ship missiles, and torpedoes. The corvette’s lighter armament reflects its patrol and surveillance duties, while the frigate’s heavier weaponry aligns with its more aggressive patrol, escort, and area defense roles.
In terms of onboard technology, frigates often carry more advanced radar and sonar systems, due to their role in anti-submarine warfare. Corvettes, being smaller, have less space for such systems and are equipped accordingly, with an emphasis on versatility and cost-efficiency for near-shore activities.
The crew size on a corvette is generally smaller because of the ship's size, resulting in more intimate quarters and a tighter shipboard community. Frigates require larger crews to manage their more complex systems and to sustain prolonged deployments.

Frigate
(historical) A sailing warship (of any size) built for speed and maneuverability; typically without raised upperworks, having a flush forecastle and tumblehome sides.
Corvette
Historically, a corvette was ranked between a sloop-of-war and a frigate in naval hierarchy.

Frigate
(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.
Frigate

Frigate
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.
Frigate
