Shchuka Class Submarine
The ''Shchuka''-class submarines (russian: Щука), also referred to as Sh or Shch-class submarines, were a medium-sized class of Soviet submarines, built in large numbers and used during World War II. "Shchuka" is Russian for pike. Of this class, only two submarines (411 and 412) entered service after 1945, although they were launched before the war. Development On 23 January 1930, the USSR Revolutionary Military Council (Revvoensoviet) adapted a proposed submarine concept that were to "execute positioning service on closed theatres". Plans were made to construct up to 200 submarines in three main versions, the later ones would be larger and with longer range than the previous versions. However, due to the outbreak of World War II, only 88 submarines were commissioned. It was still to be the second most numerous submarine class of the Soviet Navy (only the M class were more numerous with 111 built). Seven ship construction yards were involved in the program - No. 189, 190, 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Liberation Army Navy
The People's Liberation Army Navy (PLAN; ), also known as the People's Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People's Liberation Army. The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology. Until the late 1980s, the PLAN was largely a riverine and littoral force (brown-water navy). In the 1990s, following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy, the leaders of the Chinese military were freed from worrying overland border disputes. Traditionally subordinated to the PLA Ground Force, PLAN leaders were now able to advocate for a renewed attention towards the seas. Chinese military officials have outlined plans to operate in the first and second island chains, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulina
Sulina () is a town and free port in Tulcea County, Northern Dobruja, Romania, at the mouth of the Sulina branch of the Danube. It is the easternmost point of Romania. History During the mid-Byzantine period, Sulina was a small cove, and in the 14th century, a Genoese port inhabited by a handful of sailors, pirates and fishermen. In the 18th century, the Ottomans built a lighthouse there in order to facilitate communication between Constantinople (Istanbul) and the Danubian Principalities, the main breadbaskets for the Ottoman capital. Thanks to the signing of the Treaty of Adrianoupolis (Edirne) on September 2, 1829, that unfettered the Danube grain trade, Sulina, by then under Russian control, became an important port. Great sailing boats could not sail fully loaded to Brăila and Galați, which were the main export centres of Wallachia and Moldavia, because of the shallow waters of the river; therefore, they had to tranship at least part of their cargoes to smaller river ...

Snake Island (Black Sea)
Snake Island, also known as Serpent Island or Zmiinyi Island ( uk, острів Змії́ний, ostriv Zmiinyi; ro, Insula Șerpilor; russian: Змеиный, Zmeinyy), is an island belonging to Ukraine located in the Black Sea, near the Danube Delta, with an important role in delimiting Ukrainian territorial waters. The island has been known since classical antiquity, and during that era hosted a Greek temple to Achilles. Today, it is administered as part of Izmail Raion of Ukraine's Odesa Oblast. The island is populated, reported to have under 30 people in 2012. A village, Bile, was founded in February 2007 with the purpose of consolidating the status of the island as an inhabited place. This happened during the period in which the island was part of a border dispute between Romania and Ukraine from 2004 to 2009, during which Romania contested the technical definition of the island and borders around it. The territorial limits of the continental shelf around Snake Island ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shadowgraph Schuka Class V-bis Series Submarine
Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation. In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras. However, all these disturbances refract light rays, so they can cast shadows. The plume of hot air rising from a fire, for example, can be seen by way of its shadow cast upon a nearby surface by the uniform sunlight. Sunlight shadowgraph Some aquatic predators detect their transparent prey by way of their shadows cast upon the ocean floor. It was Robert Hooke who first scientifically demonstrated the sunlight shadowgraph and Jean-Paul Marat who first used it to study fire. A modern account of shadowgraphy is given by Gary S. Settles.

Soviet Submarine S-117
''S-117'' (formerly ''Shch-117'') was a Soviet (V-bis series). The submarine's career was spent with the Soviet Pacific Fleet.
