A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper 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 Hellenic Navy is the naval force of Greece, part of the Hellenic Armed Forces. The modern Greek navy historically hails from the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy it was known as the Royal Hellenic Navy.
The Valour class is a class of frigates built for the South African Navy. Part of the MEKO family of warships, the German shipbuilder Blohm+Voss officially designate the class as the MEKO A-200SAN.
The MEKO family of warships was developed by the German company Blohm+Voss. MEKO is a registered trademark. The portmanteau stands for "Mehrzweck-Kombination". It is a concept in modern naval shipbuilding based on modularity of armament, electronics and other equipment, aiming at ease of maintenance and cost reduction.
The Vasco da Gama class is a class of frigates of the Portuguese Navy. Named in honor of the Portuguese explorer Vasco da Gama, the ships are based on the German MEKO 200 design, and are Portugal's major surface ships. Portugal operates three ships of this class, which were built in Hamburg by Blohm + Voss (B&V) and by Howaldtswerke-Deutsche Werft (HDW) in Kiel, using modular construction techniques.
The Almirante Brown class is a class of warships built for the Argentine Navy. They were commissioned between 1983 and 1984, after the Falklands War. The class comprises four ships; Almirante Brown, La Argentina, Heroína and Sarandí. They are classified as either frigates or destroyers by different publications. The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements. The modular nature of the construction also allows the ships to be modernized or refitted with greater ease. Six vessels were initially ordered, however two ships were cancelled and replaced with orders for MEKO 140 type hulls.
The MEKO 360 is a class of five ships built in Germany for the Argentine and Nigerian navies. The MEKO 360 was the first version of the MEKO family of vessels built by Blohm und Voss. The type comes in two variants, the MEKO 360H1, comprising one ship, and the MEKO 360H2, comprising four ships. The alternatively classed as frigates and destroyers by different sources. The design is based on the modular concept which allows swapping out different armaments to fit mission requirements and allows easier application of upgrades and refits.
The MEKO 200 is a frigate design by the Blohm + Voss shipyard of Germany, as part of the MEKO family of warships.
The Barbaros-class frigates are among the most modern frigates in the Turkish Navy. They were designed in Germany and are part of the MEKO group of modular warships, in this case the MEKO 200 design. Two ships were built in Germany and two in Turkey with German assistance. They are larger than the previous Yavuz-class frigates and are also faster due to using CODOG machinery rather than pure diesels.
The Hydra class are a group of four frigates in service with the Hellenic Navy. They were designed in Germany and are part of the MEKO group of modular warships, in this case the MEKO 200 design. The programme was authorised in 1988 and partially paid for with FMS aid and provisioned for the commission of six vessels. The first ship was built in Germany and commissioned in 1992 but suffered a serious fire while working up near Portland, England. Repairs were completed in 1993. The Greek built warships were delayed due to financial problems on the part of the Hellenic Shipyards completing in the late 1990s which also led to limiting the total number of vessels to four mainly after the acquisition of eight Kortenaer-class frigates from the Netherlands in the late 1990s.
Hydra (F-452) is the lead ship of the Greek Hydra-class frigate and flagship of the Hellenic Navy. The ship was built in the same shipyard as the Blohm + Voss MEKO 200 frigate class, on which its design was based. Three more vessels were built by Hellenic Shipyards Co. at Skaramagas in following years. It is the fifth ship in the Hellenic Navy to bear the name Hydra.
Gölcük Naval Shipyard is a naval shipyard of the Turkish Navy within the Gölcük Naval Base on the east coast of the Sea of Marmara in Gölcük, Kocaeli. Established in 1926, the shipyard serves for the building and the maintenance of military vessels. A total of 3,221 personnel are employed at the shipyard stretching over an area of 255,526 m2 (2,750,460 sq ft) with covered structures of 121,466 m2 (1,307,450 sq ft).
