A naval ship is a military ship that is used by a navy. Naval ships are differentiated from civilian ships by construction and purpose. Generally, naval ships are damage resilient and armed with weapon systems, though armament on troop transports is light or non-existent.
The Royal Netherlands Navy is the maritime service branch of the Netherlands Armed Forces. It was founded on 8 January 1488, making it the third-oldest naval force in the world.
The Russian Navy is the naval arm of the Russian Armed Forces. It has existed in various forms since 1696. Its present iteration was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States.
The Military Sealift Command (MSC) is an organization that controls the replenishment and military transport ships of the United States Navy. Military Sealift Command has the responsibility for providing sealift and ocean transportation for all US military services as well as for other government agencies. It first came into existence on 9 July 1949 when the Military Sea Transportation Service (MSTS) became solely responsible for the Department of Defense's ocean transport needs. The MSTS was renamed the Military Sealift Command in 1970.
Underway replenishment (UNREP) or replenishment at sea (RAS) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century, it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely.
Sealift is a term used predominantly in military logistics and refers to the use of cargo ships for the deployment of military assets, such as weaponry, vehicles, military personnel, and supplies. It complements other means of transport, such as strategic airlifts, in order to enhance a state's ability to project power.
A joint support ship (JSS) is a multi-role naval vessel capable of launching and supporting joint amphibious and airlift operations. It can also provide command and control, sealift and seabasing, underway replenishment, disaster relief and logistics capabilities for combined land and sea operations.
Mobile offshore base (MOB), sometimes called a joint mobile offshore base (JMOB), is a concept for supporting military operations beyond the home shores, where conventional land bases are not available, by deploying on the high seas or in coastal waters, in-theater multipurpose floating base assembled from individual platforms. In essence, a MOB is a multipurpose modular self-propelled floating platform, or several interconnected platforms, that can perform multiple functions of a sea base including strike, deployment and logistics. An ocean-wise semi-submersible wave and wind resistant platform capable of moving at one-half the speed of conventional prepositioning monohull cargo ship has been researched and proposed, but never built.
A primary measure of a nation's power projection is its over-the-beach capability (OTB). This consists of the number of soldiers, tanks, vehicles, and helicopters that a nation can stage over an adversary's defended coast in a time of war. Generally, these elements only count if they can be projected across hundreds of kilometers of open ocean. Over-the-beach capability determines a nation's power projection together with forward airpower, alliances, and nuclear options.
Expeditionary warfare is a military invasion of a foreign territory, especially away from established bases. Expeditionary forces were in part the antecedent of the modern concept of rapid deployment forces. Traditionally, expeditionary forces were essentially self-sustaining with an organic logistics capability and with a full array of supporting arms.
United States Naval Districts is a system created by the United States Navy to organize military facilities, numbered sequentially by geographic region, for the operational and administrative control of naval bases and shore commands in the United States and around the world. Established in 1903, naval districts became the foundational system for organizing U.S. naval forces ashore during the 20th century. The term "Naval" forces includes United States Marine Corps and current United States Coast Guard units.
A line of communication is the route that connects an operating military unit with its supply base. Supplies and reinforcements are transported along the line of communication. Therefore, a secure and open line of communication is vital for any military force to continue to operate effectively. Prior to the advent of the use of the telegraph and radio in warfare, lines of communication were also the routes used by dispatch riders on horseback and runners to convey and deliver orders and battle updates to and from unit commanders and headquarters. Thus, a unit whose lines of communication were compromised was vulnerable to becoming isolated and destroyed, as the means for requesting reinforcements and resupply is lost. The standard military abbreviation is LOC. There is also SLOC for Sea Line of Communication, GLOC for Ground Line of Communication, or ALOC for Air Line of Communication.
An offensive is a military operation that seeks through an aggressive projection of armed forces to occupy or recapture territory, gain an objective or achieve some larger strategic, operational, or tactical goal. Another term for an offensive often used by the media is "invasion", or the more general "attack". An offensive is a conduct of combat operations that seek to achieve only some of the objectives of the strategy being pursued in the theatre as a whole. Commonly an offensive is carried out by one or more divisions, numbering between 10 and 30,000 troops as part of a combined arms manoeuvre.
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the world's most powerful navy and the largest by displacement, at 4.5 million tons in 2021 and in 2009 an estimated battle fleet tonnage that exceeded the next 13 navies combined. It has the world's largest aircraft carrier fleet, with 11 in service, one undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of July 18, 2023.
Seabase Delta is a text adventure game by Firebird released in 1986 for the Amstrad CPC, Commodore 64, and ZX Spectrum home computers. It is the sequel to Subsunk.
An Expeditionary Transfer Dock (ESD), formerly the Mobile Landing Platform (MLP), is designed to be a semi-submersible, flexible, modular platform providing the US Navy with the capability to perform large-scale logistics movements such as the transfer of vehicles and equipment from sea to shore. These ships significantly reduce the dependency on foreign ports and provide support in the absence of port availability. The class also houses a sub-class variant called the Expeditionary Mobile Base (ESB), formerly the Afloat Forward Staging Base (AFSB).
USNS Montford Point (T-ESD-1),, the lead ship of her class of Expeditionary Transfer Docks (ESD), is a ship named in honor of African American Marine Corps recruits who trained at Montford Point Camp, North Carolina, from 1942 to 1949. After $115 million was allocated for long-lead time material and advanced design efforts, in late 2010 General Dynamics's National Steel and Shipbuilding Company was awarded the contract, worth approximately $500 million, to build the first of three planned vessels.
The Sea Battalion is a land formation of the German Navy. It was formed in Eckernförde on 1 April 2014, succeeding the Naval Protection Force and the Naval Force Protection Battalion, against a background of rapidly escalating tensions in Eastern Europe centering around Ukraine.
Sotenäs is a wave farm located in Kungshamn, in the municipality of Sotenäs, Sweden. The facility consists of 36 wave energy converters (WECs), with a total installed capacity of nearly 1 MW. Each WEC generates power using point absorber buoys connected to linear generators on the seabed. The generators are located at a depth of 50 m (160 ft). According to Seabased, the technology used in the project could deliver electricity for under 10 cents per kWh. Initial announcements stated that the power plant would eventually expand to around 10 MW capacity, but in 2017 Seabased announced it would no longer expand the plant beyond the 36 WECs already in place. The Sotenäs wave park was not in operation between 2016-2020, with no buoys connected to the gravity-based PTOs. The site remains inactive, and is studied as an example of an artificial reef.
Ocean development refers to the establishing of human activities at sea and use of the ocean, as well as its governance.
