The Seawolf class is a class of nuclear-powered, fast attack submarines (SSN) in service with the United States Navy. The class was the intended successor to the Los Angeles class, and design work began in 1983. A fleet of 29 submarines was to be built over a ten-year period, but that was reduced to 12 submarines. The end of the Cold War and budget constraints led to the cancellation of any further additions to the fleet in 1995, leaving the Seawolf class limited to just three boats. This, in turn, led to the design of the smaller Virginia class. The Seawolf class cost about $3 billion per unit, making it the most expensive United States Navy fast attack submarine and second most expensive submarine ever, after the French Triomphant-class nuclear-powered ballistic missile submarines.
The Virginia class, or the SSN-774 class, is the newest class of nuclear-powered cruise missile fast attack submarines in service with the United States Navy. The class is designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to operate into the 2070s.
The Royal Danish Navy is the sea-based branch of the Danish Armed Forces force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish territorial waters. Other tasks include surveillance, search and rescue, icebreaking, oil spill recovery and prevention as well as contributions to international tasks and forces.
A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
The MEKO family of warships was developed by the German company Blohm+Voss. MEKO is a registered trademark. The portmanteau stands for "Mehrzweck-Kombination". It is a concept in modern naval shipbuilding based on modularity of armament, electronics and other equipment, aiming at ease of maintenance and cost reduction.
The Flyvefisken-class patrol vessels are warships of the Royal Danish Navy. The class is also known as the Standard Flex 300 or SF300 class. The five vessels sold to the Portuguese Navy are locally referred as Tejo class.
The Type 052B is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052B was China's first modern destroyer design and the first Chinese design to incorporate true medium-range air defence capability in the form of Russian Shtil-1 surface-to-air missiles (SAM).
The LR5 is a crewed submersible which was used by the British Royal Navy until 2009 when it was leased to support the Royal Australian Navy. It is designed for retrieving sailors from stranded submarines and is capable of rescuing 16 at a time. The Royal Navy now has the use of the NATO Submarine Rescue System.
A deep-submergence rescue vehicle (DSRV) is a type of deep-submergence vehicle used for rescue of personnel from disabled submarines and submersibles. While DSRV is the term most often used by the United States Navy, other nations have different designations for their equivalent vehicles.
The Scorpène-class submarines are a class of diesel-electric attack submarines jointly developed by the French Naval Group and the Spanish company Navantia. It features diesel propulsion and an additional air-independent propulsion (AIP). It is now marketed as the Scorpène 2000.
INS Ranvijay is a Rajput-class destroyer in active service with the Indian Navy. Ranvijay was commissioned on 15 Jan 1988.
The Shirane-class destroyers were a pair of Japanese destroyers originally built during the late 1970s. They are built around a large central hangar which houses up to three helicopters and they are the natural successor of the Haruna-class destroyers.
The Zubr class, Soviet designation Project 1232.2, is a class of Soviet-designed air-cushioned landing craft (LCAC). The name "Zubr" is Russian for the European bison. This class of military hovercraft is, as of 2023 the world's largest hovercraft, with a standard full load displacement of 555 tons. The hovercraft was designed to sealift amphibious assault units from equipped/non-equipped vessels to non-equipped shores, as well as to transport and plant naval mines.
The Iver Huitfeldt class is a three-ship class of air defence frigates that entered service with the Royal Danish Navy in 2012 and 2013.
The General Electric LM500 is an industrial and marine gas turbine produced by GE Aviation. The LM500 is a derivative of the General Electric TF34 aircraft engine. Current versions of the LM500 deliver 6,000 shaft horsepower with a thermal efficiency of 31 percent at ISO conditions. It has been used in various applications such as in the Royal Danish Navy's Flyvefisken class patrol vessels, and in fast ferries.
The Double Eagle is a remotely operated vehicle (ROV) built by the Swedish defence company Saab Underwater Systems AB and used for the disposal of naval mines.
StanFlex is a modular mission payload system used by the Royal Danish Navy. Originally conceived during the 1980s as a way of replacing several classes of minor war vessel with a single class of multi-role ships, the StanFlex system consists of weapons and equipment mounted in standardised containers, which can be loaded into slots on the ships. These containers can be swapped out in a short period of time, allowing the ship to switch between roles when needed. The success of the modular payload system led the Royal Danish Navy to design all new warships with StanFlex slots, and to install slots on older vessels during major refits. By 2012, nine ship classes capable of carrying StanFlex payloads were in service.
The TRML is a family of air defense radars first developed by Telefunken and currently produced by Hensoldt. It is a development of the earlier TRMS.
