Corvette

A corvette or corvet is a small warship.^[1] It is traditionally the smallest class of vessel considered to be rated a 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 roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 and 2,000 tons. 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. However unlike contemporary frigates, a modern corvette does not have sufficient endurance or seaworthiness for long voyages. The word "corvette" is first found in Middle French, a diminutive of the Dutch word corf, meaning a "basket", from the Latin corbis.^[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, Germany, 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.

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 Royal 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 Royal 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.^{[citation needed]}

The last vessel lost by France during the American Revolutionary War was the corvette Le Dragon, scuttled by her captain to avoid capture off Monte Cristi Province, Saint-Domingue on January 1783.^[4] Most corvettes and sloops of the 17th century were 12 to 18 m (40 to 60 ft) in length and measured 40 to 70 tons burthen. They carried four to eight smaller guns on single decks. Over time, vessels of increasing size and capability were called "corvettes"; by 1800, they reached lengths of over 30 m (100 ft) and measured from 400 to 600 tons burthen.^{[citation needed]}

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 Tribal-class destroyer. 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.^{[citation needed]}

This idea was dropped, and the term applied to small, mass-produced antisubmarine escorts such as the Flower-class corvette of World War II. (Royal Navy ships 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. HMCS Sackville is the only remaining member of the class. She is preserved as a museum ship in Halifax, Nova Scotia, Canada.

The Flower-class corvette was originally designed for offshore patrol work, and was not ideal when pressed into service as an antisubmarine escort. It was shorter than ideal for oceangoing convoy escort work, too lightly armed for antiaircraft defense, and the ships were barely faster than the merchantmen they escorted. This was a particular problem given the faster German U-boat designs then emerging. Nonetheless, the ship was quite seaworthy and maneuverable, but living conditions for ocean voyages were challenging. As a result of these shortcomings, 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 Castle-class corvette, was introduced later in the war, with some remaining in service until the mid-1950s.

The Royal Australian Navy built 60 Bathurst-class corvettes, 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.^{[citation needed]}

The Bird-class minesweepers or trawlers were referred to as corvettes in the Royal New Zealand Navy, and two, HMNZS Kiwi and HMNZS Moa, rammed and sank a much larger Japanese submarine, , in 1943 in the Solomon Islands.

In Italy, the Regia Marina, in dire need of escort vessels for its convoys, designed the Gabbiano-class corvette, 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.^{[citation needed]}

Modern corvettes

Modern navies began a trend in the late 20th and early 21st centuries of building corvettes geared towards smaller more manoeuvrable surface capability. These corvettes have displacements between 550 and 3,310 short tons (500 and 3,000 tonnes) and measure 55–128 m (180–420 ft) in length. They are usually armed with medium- and small-calibre guns, surface-to-surface missiles, surface-to-air missiles (SAM), and anti-submarine weapons. Many can accommodate a small or medium anti-submarine warfare helicopter, with the larger ones also having a hangar. While the size and capabilities of the largest corvettes overlap with smaller frigates, corvettes are designed primarily for littoral deployment while frigates are ocean-going vessels by virtue of their greater endurance and seaworthiness.^{[citation needed]}

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. 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.

In the 1960s, the Portuguese Navy designed the João Coutinho-class corvettes as multi-role small frigates intended to be affordable for a small navy. The João Coutinho class soon inspired a series of similar projects – including the Spanish Descubierta-class corvette, the German MEKO 140, the French A69 and the Portuguese Baptista de Andrade-class corvette – adopted by a number of medium- and small-sized navies.

The first operational corvette based on stealth technology was the Royal Norwegian Navy's Skjold-class patrol boat. The Swedish Navy introduced the similarly stealthy Visby-class corvette.

Finland has plans to build four multi-role corvettes, currently dubbed the Pohjanmaa-class corvette, 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 (330 ft) long and cost a total of 1.2 billion euros.

The new German Navy Braunschweig-class corvette is designed to replace Germany's fast attack craft and also incorporates stealth technology and land attack capabilities. The Israeli Navy has ordered four of these, named Sa'ar 6-class corvettes and a more heavily armed version of the type, deliveries commenced in 2019.^{[citation needed]}

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

The Indian Navy operates four Kamorta-class corvettes built by Garden Reach Shipbuilders and Engineers. All of them were in service by 2017. Also Anti-Submarine Warfare Shallow Water Craft corvettes are getting inducted into service.^[6]

The Israeli Navy operates three Sa'ar 5-class corvettes and four Sa'ar 6-class corvettes. The Sa'ar 5's were built in the U.S. to an Israeli design, they each 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 Sa'ar 6's were built in Germany to an Israeli design. They are equipped with a 76 mm main gun, anti-ship missiles, torpedoes, and defense systems like the "Naval Dome" for missile interception, making them exceptionally well-armed for their size of 1,900 tons.

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 Freedom-class littoral combat ship of littoral combat ships of the United States.^{[citation needed]}

In 2004, to replace the Ardhana-class patrol craft patrol boat, the United Arab Emirates Ministry of Defence awarded a contract to Abu Dhabi Ship Building for the Baynunah-class corvette of corvettes. This class is based on the CMN Group's Combattante BR70 design. The Baynunah class is designed for patrol and surveillance, minelaying, interception and other anti-surface warfare operations in the United Arab Emirates territorial waters and exclusive economic zone.

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 Oliver Hazard Perry-class frigate.^{[citation needed]}
