Roussen-class Fast Attack Craft
The ''Roussen'' class is a seven-strong class of British-designed fast attack missile boats improved and customized for the Hellenic Navy, also known as ''Super Vita''. The class is named after its lead ship, which in turn is named after Lt Nikolaos Roussen, a World War II submarines officer who was killed in the suppression of the Navy mutiny in April 1944. History The modernization program of the Hellenic Navy in the late 1990s included the construction of three modern missile boats and was signed in January 2000. The construction took place at the Elefsis Shipyards, while Vosper Thornycroft (now BAE Systems Surface Ships) provided the necessary design, logistical support and equipment for the ships. In August 2003 and September 2008 options that provided for the acquisition of four more vessels were taken up with the last ship to be commissioned in 2015. On 25 September 2008, a 299 million Euro contract was signed between the Greek State and the Elefsis Shipyards for the con ...

Battle Of Chios (1912)
The Battle of Chios took place from 24 November 1912 to 3 January 1913 during the First Balkan War. It resulted in the capture of the eastern Aegean island of Chios by the Kingdom of Greece, ending almost 350 years of rule by the Ottoman Empire. The occupation of the island was a prolonged affair. The Greek landing force, commanded by Colonel Nikolaos Delagrammatikas, was quickly able to seize the eastern coastal plain and the Chios (town), town of Chios, but the Ottoman garrison was well equipped and supplied, and managed to withdraw to the mountainous interior. A stalemate ensued, and operations almost ceased from the end of November and until the arrival of Greek reinforcements in late December. Finally, the Ottoman garrison was defeated and forced to surrender on 3 January 1913. Background The island of Chios had been ruled by the Ottoman Empire since 1566, when it was seized from the tributary Republic of Genoa, Genoese ''Maona di Chio e di Focea, Maona'' company as a r ...

3D Radar
3D radar provides for radar ranging and direction in three dimensions. In addition to range, the more common two-dimensional radar provides only azimuth for direction, whereas the 3D radar also provides elevation. Applications include weather radar, weather monitoring, air defense, and surveillance. The information provided by 3D radar has long been required, particularly for air defence and Ground-controlled interception, interception. Interceptors must be told the altitude to climb to before making an intercept. Before the advent of single unit 3D radars, this was achieved with separate search radars (giving range and azimuth) and separate height finding radars that could examine a target to determine altitude. These had little search capability, so were directed to a particular azimuth first found by the primary search radar. Techniques Steered beam radars steer a narrow beam through a scan pattern to build a 3-D picture. Examples include NEXRAD Pulse-Doppler radar, Doppler ...

Mark 36 SRBOC
The BAE Systems Mark 36 Super Rapid Bloom Offboard Countermeasures Chaff and Decoy Launching System (abbreviated as SRBOC or "Super-arboc") is an American short-range decoy launching system (DLS) that launches radar or infrared decoys from naval vessels to foil incoming anti-ship missiles. The decoys present false signals and interference to the attacking missiles' guidance and fire-control systems. Description The Mark 36 SRBOC uses the Mark 137 launcher, which has six fixed 130 mm mortar tubes arranged in two parallel rows. One row is set at 45 degrees and the other is set at 60 degrees, providing a spread of the launched decoys. Firing circuits use electromagnetic induction to set off the propelling charges in the decoy cartridges. They are launched at a speed of 75 m/s. Each launcher holds 12–36 rounds, depending on variant. The number and arrangement of Mk 36 launchers installed depends on the size of the ship, ranging from two launchers on a small combatant to as m ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its Mast (sailing), masts or any armament gun turret, turrets. Note that, in modern times, turrets do not always carry naval artillery. They can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure ...

Autocannons have a longer effective range and greater terminal ballistics, terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns, or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single gun barrel, barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or "rotary cannon".
