Шаблон:Infobox ship imageШаблон:Infobox ship careerШаблон:Infobox ship characteristicsXifias (Шаблон:Lang-el, "swordfish") was a Greek submarine (actually called a "submersible", καταδυόμενον, according to the then current French terminology) which served during World War I. It was the third submarine to enter service in the Greek navy, and the second and last vessel of the Delfin class. It was taken over by the French in 1916, and decommissioned in 1920 without seeing action.
Design and description
The submarine displaced Шаблон:Convert surfaced and Шаблон:Convert submerged. She measured Шаблон:Convert between perpendiculars, had a beam of Шаблон:Convert and a draft of Шаблон:Convert. Delfin had an operational diving depth of Шаблон:Convert and a maximum diving depth of Шаблон:Convert. Its complement consisted of 19 men.Шаблон:SfnШаблон:SfnШаблон:Sfn
Her hull was divided into seven compartments and she was fitted with seven external ballast tanks. The small depth of the flood port in the stern ballast tank meant that it took longer to fill; it was therefore always filled first. Diving was performed with the flood ports closed and the vent valves open, in order to prevent a negative inclination from the inflow of water in the bow and stern ballast tanks. Her rudder was manually controlled from the central compartment and the conning tower. It had two electrical periscopes, the stern periscope was operated from the central compartment while the bow periscope was controlled from the conning tower. Neither of which could modify their magnification or make observations above the line of the horizon. Xifias had three diving planes, the bow and stern ones were below the waterline, while the middle one was above the waterline. Schneider-Laubeuf type submarines had high levels of buoyancy (30-35%) and a complete light hull which protected the pressure hull.Шаблон:Sfn
For surface running, the boat was powered by two Schneider-Carels diesel engines which were heated by compressed air for 10-15 minutes by their corresponding two electric motors before starting. The electric motors used 94-cell batteries. The fuel used was gasoline bordering on paraffin. When submerged the propellers were driven by two Schneider electric motor using electricity from two 192-cell batteries. Xifias could reach Шаблон:Convert on the surface and Шаблон:Convert underwater. On the surface, the boat had a range of Шаблон:Convert, submerged, she had a range of Шаблон:Convert at Шаблон:Convert.Шаблон:SfnШаблон:Sfn
She was armed with one internal Шаблон:Convert torpedo tube in the bow and four Drzewiecki drop collars (two in the bow and two in the stern). She bore six Schwartzkopff type Шаблон:Convert torpedoes, one in the torpedo tube, one in each frame and one stored in the bow compartment.Шаблон:SfnШаблон:Sfn
Construction and service
Construction and delivery
The Hellenic Navy underwent a major reorganization and rearmament in the aftermath of the 1909 Goudi coup. The putschists pressured the Greek government into ordering submersibles (as submarines were known at the time). Thus submersible Delfin and its sister ship Xifias were ordered from the Schneider Shipyards at Chalon-sur-Saône, France in September 1910. Xifias was named after Greek word for swordfish. The submarine was designed by naval architect Maxime Laubeuf.Шаблон:SfnШаблон:Sfn
She was delivered to the Hellenic Navy in March 1913, shortly after the end of the First Balkan War. It was thus unable to participate in any naval operations against the Ottoman fleet.[1]
Service
The French news-photograph concern Agènce Rol produced a series of photographs of Xifias undergoing diving and submerged torpedo-firing tests off Toulon in June 1913. Like its sister ship, Xifias was plagued by mechanical problems and had insufficient operational capabilities; as a consequence, its use was minimal in the years that followed. Xifias and the rest of the Greek fleet were confiscated by the French in October 1916, during the Greek National Schism. When the ships were returned in 1918, the two submarines were in a bad shape, and the following year, they were decommissioned.[1]
Tradition
A second vessel of the Hellenic Navy has received the name Xifias: the British U-class submarine Шаблон:HMS, which was leased to Greece in 1945–1952.
