SM U-XXIII (Austria-Hungary)
SM ''U-23'' or ''U-XXIII'' was a or U-boat built for and operated by the Austro-Hungarian Navy ( or ) during the First World War. The design for ''U-23'' was based on that of the submarines of the Royal Danish Navy's Havmanden class submarine (1911), ''Havmanden'' class (which had been designed by Whitehead & Co. in Fiume), and was largely obsolete by the beginning of the war. ''U-23'' was just over long and was armed with two bow torpedo tubes, a deck gun, and a machine gun. In February 1918, ''U-23'' was sunk with all hands by the Italian torpedo boat ''Airone'' while attempting an attack on the Italian transport . ''U-23'' had no wartime successes.

Sister Ship
A sister ship is a ship of the same Ship class, 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 trio, consisting of , and . As with some other liners, the sisters worked as running mates. Of the three sister ships, ''Titanic'' and ''Britannic'' would both sink within a year of being launched, while RMS ''O ...

Paravane (weapon)
The paravane is a towed winged (hydrofoiled) underwater object—a water kite. Paravanes have been used in sport or commercial fishing, marine exploration and industry, sports and military applications. The wings of paravanes are sometimes in a fixed position, else positioned remotely or by actions of a human pilot. Pioneer parafoil developer Domina Jalbert considered water kites hardly different from air kites. However, paravanes generally orient themselves in respect to the water surface. They may have sensors that record or transmit data or are used entirely for generating a holding force like a sea anchor does. While a sea-anchor allows a vessel to drift more slowly downwind, the paravane travels sideways to the pull at one to several times the pulling speed. Paravanes are, like air kites, often symmetrical in one axis and travel in two directions, the change being effected by gybing, shunting, or flipping over. Military applications The paravane , a form of towed underwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Straits Of Otranto
The Strait of Otranto (; ) connects the Adriatic Sea with the Ionian Sea and separates Italy from Albania. Its width between Punta Palascìa, eastern Salento, and Karaburun Peninsula, western Albania, is less than . The strait is named after the Italian city of Otranto. History Since ancient times, the Strait of Otranto was of vital strategic importance. The Romans used it to transport their troops eastwards. The legions marched to Brundisium (now Brindisi), had only a one-day sea voyage to modern Albania territory and then could move eastwards following the Via Egnatia. World War I During World War I, the strait was of strategic significance. The Allied navies of Italy, France, and Great Britain, by blockading the strait, mostly with light naval forces and lightly armed fishing vessels known as drifters, hindered the cautious Austro-Hungarian Navy from freely entering the Mediterranean Sea, and effectively kept them out of the naval theatre of war. The blockade was k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ship naming and launching endow a ship hull with her identity, but many milestones remain before it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship.
