Greek Battleship Spetsai
''Spetsai'' (Greek: ''Θ/Κ Σπέτσαι'') was a Greek ironclad battleship of the that served in the Royal Hellenic Navy from 1890 until 1920. She was named after the Saronic Gulf island of Spetses, which played a key role in the war at sea during the Greek War of Independence. ''Spetsai'' she was ordered in 1885 in response to a crisis in the Balkans and Ottoman naval expansion. The ship was launched in 1889 and delivered to Greece by 1902. She was armed with a main battery of three guns and five guns, and had a top speed of . ''Spetsai'' and her sisters saw extensive service with the Greek Navy. They participated in the Greco–Turkish War in 1897 until the Great Powers intervened and prevented the Greek Navy from capitalizing on their superiority over the Ottoman Navy. ''Psara'' saw action in the First Balkan War at the Naval Battle of Elli and was present at the Naval Battle of Lemnos, but was too slow to actively engage the Ottoman forces. She did not see action dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek War Of Independence
The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. The Greeks were later assisted by the British Empire, Bourbon Restoration in France, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their North African vassals, particularly the eyalet of Egypt Eyalet, Egypt. The war led to the formation of modern Greece. The revolution is Celebration of the Greek Revolution, celebrated by Greeks around the world as Greek Independence Day, independence day on 25 March. Greece, with the exception of the Ionian Islands, came under Ottoman rule in the 15th century, in the decades before and after the fall of Constantinople. During the following centuries, there were sporadic but unsuccessful Ottoman Greece#Uprisings before 1821, Greek uprisings against Ottoman rule. In 1814, a secret organization called Filiki Et ...

Main Battery
A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a gun or group of guns, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles as a vessel's principal offensive weapon, deployed both on surface ships and submarines. A main battery features common parts, ammunition, and fire control across the weapons which it comprises. Description In the age of cannon at sea, the main battery was the principal group of weapons around which a ship was designed, usually its heavies. With the coming of naval rifles and subsequent revolving gun turrets, the main battery became the principal group of heaviest guns, regardless of how many turrets they were placed in. As missiles displaced guns both above and below the water their principal group became a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are fro ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured paral ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Naval Battle Of Lemnos
The Second Battle of Lemnos ( el, Ναυμαχία της Λήμνου, tr, Mondros Deniz Muharebesi), fought on , was a naval battle during the First Balkan War, in which the Greeks defeated the second and last attempt of the Ottoman Empire to break the Greek naval blockade of the Dardanelles and reclaim supremacy over the Aegean Sea. This, the final naval battle of the First Balkan War, forced the Ottoman Navy to retreat to its base within the Dardanelles, from which it did not venture for the rest of the war, thus ensuring the dominion of the Aegean Sea and the Aegean islands by Greece. Prelude Following the loss of a number of Aegean Islands to Greece during the first phase of the war in 1912, and its first defeat at the Battle of Elli, the Ottoman Navy sought to check Greek progress by destroying the Greek fleet docked at the port of Moudros, Lemnos. However, it faced the problem of countering the Greek flagship, the , which had already defeated them at Elli. The Ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Battle Of Elli
The Battle of Elli ( el, Ναυμαχία της Έλλης, tr, İmroz Deniz Muharebesi) or the Battle of the Dardanelles took place near the mouth of the Dardanelles on as part of the First Balkan War between the fleets of the Kingdom of Greece and the Ottoman Empire. It was the largest sea battle of the Balkan Wars. Background Since the start of the war the Hellenic Navy acted aggressively, while the Ottoman navy remained in the Dardanelles. Admiral Kountouriotis landed at Lemnos, while the Greek fleet liberated a series of islands. On 24 October (O.S.), Kountouriotis sent a telegram to the Ottoman admiral: ''"We have captured Tenedos. We await the exit of your fleet. If you need coal, I can supply you."'' On 3 December (OS), the Ottoman fleet left the Dardanelles. Battle The Royal Hellenic Navy, led by Rear Admiral Pavlos Kountouriotis on board of the flagship ''Averof'', defeated the Ottoman Navy, led by Captain Ramiz Bey, just outside the entrance to the Dardanelles ...

First Balkan War
The First Balkan War ( sr, Први балкански рат, ''Prvi balkanski rat''; bg, Балканска война; el, Αʹ Βαλκανικός πόλεμος; tr, Birinci Balkan Savaşı) lasted from October 1912 to May 1913 and involved actions of the Balkan League (the Kingdoms of Bulgaria, Serbia, Greece and Montenegro) against the Ottoman Empire. The Balkan states' combined armies overcame the initially numerically inferior (significantly superior by the end of the conflict) and strategically disadvantaged Ottoman armies, achieving rapid success. The war was a comprehensive and unmitigated disaster for the Ottomans, who lost 83% of their European territories and 69% of their European population.''Balkan Savaşları ve Balkan Savaşları'nda Bulg ...
