Delta III-class Submarine
The Delta III-class submarine, Soviet designation Project 667BDR ''Kaľmar'' (Squid), is a large ballistic missile submarine operated by the Russian Navy. Like other previous s, the Delta III class is a double hulled design, with a thin low magnetic steel outer hull wrapped around a thicker inner pressure hull. Design The technical description and requirements for a new ballistic missile submarine were published in 1972. Development of Project 667BDR was begun at the Rubin Central Design Bureau for Marine Engineering under the direction of main designer Sergeiy Nikiticz Kovalev (Сергей Никитич Ковалёв). The submarine was to be a successor to the project 667BD. The Delta III-class submarines are significantly quieter and have a higher missile section for newer, longer-ranged missiles. The hull is divided into ten waterproof sections. The first, third, and tenth sections are emergency sections with escape hatches and transverse struts added to increase pressu ...

Liquid Rocket Propellants
The highest specific impulse chemical rockets use liquid propellants ( liquid-propellant rockets). They can consist of a single chemical (a monopropellant) or a mix of two chemicals, called bipropellants. Bipropellants can further be divided into two categories; hypergolic propellants, which ignite when the fuel and oxidizer make contact, and non-hypergolic propellants which require an ignition source. About 170 different propellants made of liquid fuel have been tested, excluding minor changes to a specific propellant such as propellant additives, corrosion inhibitors, or stabilizers. In the U.S. alone at least 25 different propellant combinations have been flown. As of 2020, no completely new propellant has been used since the mid-1970s. Many factors go into choosing a propellant for a liquid-propellant rocket engine. The primary factors include ease of operation, cost, hazards/environment and performance. History Development in early 20th century Konstantin Tsiolkovsky pro ...

Dissolution Of The Soviet Union
The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Soviet Union (USSR) which resulted in the end of the country's and its federal government's existence as a sovereign state, thereby resulting in its constituent republics gaining full sovereignty on 26 December 1991. It brought an end to General Secretary Mikhail Gorbachev's (later also President) effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of fifteen top-level republics that served as homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics alre ...

Zvezda Shipyard
Zvezda Shipbuilding Complex (russian: Судостроительный комплекс «Звезда») is a Russian shipbuilding company that operates the country's largest shipyard in the town of Bolshoy Kamen in the Russian Far East. Established in 2015 by a consortium of investors led by the Russian oil company Rosneft, the company has since attracted a large number of orders for oil tankers, LNG carriers and icebreakers. Description The main production facilities at Zvezda Shipbuilding Complex, built at and around the site of the old Zvezda Shipyard, include a graving dock and a horizontal slipway served by a 40,000-tonne floating transfer dock capable of launching hulls. Both production lines are served by 1200-tonne gantry cranes as well as numerous smaller cranes. History At the end of the Cold War, the Zvezda shipyard was used to decommission Soviet nuclear submarines, with funding and support from the US and Canada under the Nunn–Lugar Cooperative Threat Reduct ...

Barents Sea
The Barents Sea ( , also ; no, Barentshavet, ; russian: Баренцево море, Barentsevo More) is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters.World Wildlife Fund, 2008. It was known among Russians in the Middle Ages as the Murman Sea ("Norse Sea"); the current name of the sea is after the historical Netherlands, Dutch navigator Willem Barentsz. The Barents Sea is a rather shallow Continental shelf, shelf sea, with an average depth of , and it is an important site for both fishing and hydrocarbon exploration.O. G. Austvik, 2006. It is bordered by the Kola Peninsula to the south, the shelf edge towards the Norwegian Sea to the west, and the archipelagos of Svalbard to the northwest, Franz Josef Land to the northeast and Novaya Zemlya to the east. The islands of Novaya Zemlya, an extension of the northern end of the Ural Mountains, separate the Barents Sea from the Kar ...

Sea Trial
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a " shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ...
