The rank is the most junior of three "captain" ranks in several European (e.g., France, Spain, Italy, Croatia) and South American (e.g., Argentina, Chile, Brazil, Colombia) navies, because a corvette, as the smallest class of rated warship, was traditionally the smallest class of vessel entitled to a commander of a "captain" rank. The rank " corvette captain", equivalent in many navies to " lieutenant commander", derives from the name of this type of ship. The word "corvette" is first found in Middle French, a diminutive of the Dutch word corf, meaning a "basket", from the Latin corbis. However unlike contemporary frigates, a modern corvette does not have sufficient endurance or seaworthiness for long voyages. Recent designs of corvettes may approach 3,000 tons and include a hangar to accommodate a helicopter, having size and capabilities that overlap with smaller frigates. These corvettes are typically between 500 and 2,000 tons. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. It is traditionally the smallest class of vessel considered to be a proper (or " rated") warship. Anti-submarine-warfare corvette INS Kamorta of the Indian NavyĪ corvette is a small warship.
