A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or "rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ship below a corvette are coastal patrol craft and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons[1] although recent designs may approach 3,000 tons, which might instead be considered a small frigate.

The word "corvette" is first found in Middle French, a diminutive of the Dutch word corf, meaning a small ship, from the Latin corbis, meaning "basket".[2]

The rank "corvette captain", equivalent in many navies to "lieutenant commander", derives from the name of this type of ship. 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) 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.

Sailing vessels

During the Age of Sail, corvettes were one of many types of warships smaller than a frigate and with a single deck of guns.[3] They were very closely related to sloops-of-war. The role of the corvette consisted mostly of coastal patrol, fighting minor wars, supporting large fleets, or participating in show-the-flag missions. The English Navy began using small ships in the 1650s, but described them as sloops rather than corvettes. The first reference to a corvette was with the French Navy in the 1670s, which may be where the term originated. The French Navy's corvettes grew over the decades and by the 1780s they were ships of 20 guns or so, approximately equivalent to the British Navy's post ships. The British Navy did not adopt the term until the 1830s, long after the Napoleonic Wars, to describe a small sixth-rate vessel somewhat larger than a sloop.

The last vessel lost by France during the American War of Independence was the Corvette Le Dragon, scuttled by her Captain to avoid being seized by a British squadron off Monte Cristi , Haïti in January 1783.[4]

Most corvettes and sloops of the 17th century were around 40 to 60 ft (12 to 18 m) in length and measured 40 to 70 tons burthen. They carried four to eight smaller guns on a single deck. Over time, vessels of increasing size and capability were called corvettes; by 1800, they reached lengths of over 100 ft (30 m) and measured from 400 to 600 tons burthen.

Steam ships

Ships during the steam era became much faster and more manoeuvrable than their sail ancestors. Corvettes during this era were typically used alongside gunboats during colonial missions. Battleships and other large vessels were unnecessary when fighting the indigenous people of the Far East and Africa.

World War II

The modern corvette appeared during World War II as an easily built patrol and convoy escort vessel.[3] The British naval designer William Reed drew up a small ship based on the single-shaft Smiths Dock Company whale catcher Southern Pride, whose simple design and mercantile construction standards lent itself to rapid production in large numbers in small yards unused to naval work. First Lord of the Admiralty Winston Churchill, later Prime Minister, had a hand in reviving the name "corvette".

During the arms buildup leading to World War II, the term "corvette" was almost attached to the Template:Sclass2-. The Tribals were so much larger than and sufficiently different from other British destroyers that some consideration was given to resurrecting the classification of "corvette" and applying it to them. This idea was dropped, and the term applied to small, mass-produced antisubmarine escorts such as the Template:Sclass2- of World War II.

The first modern corvettes were the Flower class (Royal Navy corvettes were named after flowers, and ships in Royal Canadian Navy service took the name of smaller Canadian cities and towns). Their chief duty was to protect convoys throughout the Battle of the Atlantic and on the routes from the UK to Murmansk carrying supplies to the Soviet Union.

The Flower-class corvette was originally designed for offshore patrol work, and was not ideal as an antisubmarine escort; they were really too short for open ocean work, too lightly armed for antiaircraft defence, and little faster than the merchantmen they escorted, a particular problem given the faster German U-boat designs then emerging. They were very seaworthy and maneuverable, but living conditions for ocean voyages were appalling. Because of this, the corvette was superseded in the Royal Navy as the escort ship of choice by the frigate, which was larger, faster, better armed, and had two shafts. However, many small yards could not produce vessels of frigate size, so an improved corvette design, the Template:Sclass2-, was introduced later in the war, with some remaining in service until the mid-1950s.

The Royal Australian Navy built 60 Template:Sclass-s, including 20 for the Royal Navy crewed by Australians, and four for the Indian Navy. These were officially described as Australian minesweepers, or as minesweeping sloops by the Royal Navy, and were named after Australian towns.

The Template:Sclass2-s or trawlers were referred to as corvettes in the Royal New Zealand Navy, and two, Kiwi and Moa, rammed and sank a much larger Japanese submarine, I-1, in 1943 in the Solomon Islands.

In Italy, the Regia Marina, in dire need of escort vessels for its convoys, designed the Template:Sclass-, of which 29 were built between 1942 and 1943 (out of 60 planned); they proved apt at operations in the Mediterranean Sea, especially in regards to their anti-air and anti-submarine capability, and were so successful that the class survived after the war into the Marina Militare Italiana until 1972.

Modern navies began a trend in the late 20th and early 21st centuries towards smaller, more manoeuvrable surface capability. Corvettes have a displacement between 540 and 3,000 long tons (550 and 3,050 t) and measure 180–420 ft (55–128 m) in length. They are usually armed with medium- and small-caliber guns, surface-to-surface missiles, surface-to-air missiles, and antisubmarine weapons. Many can accommodate a small or medium antisubmarine warfare helicopter.

Most countries with coastlines can build corvette-sized ships, either as part of their commercial shipbuilding activities or in purpose-built yards, but the sensors, weapons, and other systems required for a surface combatant are more specialized and are around 60% of the total cost. These components are purchased on the international market.[5]

Current corvette classes

Many countries today operate corvettes; some include Argentina,[6] Bangladesh, Brazil, Bulgaria, China, Denmark, Germany, Egypt, India, Indonesia, Iran, Israel, Italy, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, Singapore, South Korea, Sweden, Malaysia and Turkey. Countries that border smaller seas, such as the Baltic Sea or the Persian Gulf, are more likely to build the smaller and more manoeuvrable corvettes, with Russia operating the most corvettes in the world.

Kamorta-class stealth corvettes of Indian Navy

In the 1960s, the Portuguese Navy designed the Template:Sclass-s as multi-role small frigates intended to be affordable for a small navy. The João Coutinho class would soon inspire a series of similar projects – including the Spanish Template:Sclass-, the German MEKO 140, the French A69 and the own Portuguese Template:Sclass- – adopted by a number of medium and small sized navies.

The first operational corvette based on stealth technology was the Royal Norwegian Navy's Template:Sclass-. The Swedish Navy introduced the similarly stealthy Template:Sclass-.

The United States is developing littoral combat ships, which are essentially large corvettes, their spacious hulls permitting space for mission modules, allowing them to undertake tasks formerly assigned to specialist classes such as minesweepers or the anti-submarine Template:Sclass-.

The Israeli navy operates three Template:Sclass2-s. Built in the U.S to an Israeli design, they carry one helicopter and are well-armed with offensive and defensive weapons systems, including the Barak 8 SAM, and advanced electronic sensors and countermeasures. They displace over 1,200 tons at full load.

The Indian Navy plans to operate four Template:Sclass-s being built by Garden Reach Shipbuilders and Engineers. The first corvette of this class, INS Kamorta, was commissioned in Navy on 23 August 2014. The second corvette, INS Kadmatt was commissioned in Navy on 7 January 2016. The remaining two will be commissioned by 2017.

The new German Navy Template:Sclass- is designed to supplement Germany's fast attack craft and also incorporates stealth technology and land attack capabilities. The Israeli Navy has ordered four Template:Sclass2-s, a more heavily armed version of the type, deliveries commencing in 2019.

Turkey began to build MİLGEM-class corvettes in 2005. The MİLGEM class is designed for anti-submarine warfare and littoral patrol duty. The lead ship, TCG Heybeliada, entered navy service in 2011. The design concept and mission profile of the MİLGEM class is similar to the Template:Sclass- of littoral combat ships of the United States.

Finland has plans to build four multirole corvettes in the 2020s as part of its navy's Project Squadron 2020. The corvettes will have helicopter carrying, mine laying, ice breaking, anti-aircraft and anti-ship abilities. They will be over 100 metres long and cost a total of 1.2 billion euros.

The Greek Navy has categorised the class as fast attack missile craft. A similar vessel is the Template:Sclass- fast attack missile craft of the Turkish Navy, which is classified as a corvette by Lürssen Werft, the German ship designer.
