A remotely operated underwater vehicle (ROUV) or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general tasks within the subsea oil and gas industry, military, scientific and other applications. ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of flexible flowlines and umbilicals, and component replacement. They are often used to visit wrecks at great depths beyond the capacities of submersibles for research purposes, such as the Titanic, amongst others.
USS Hartford (SSN-768), a Los Angeles-class submarine, is the second ship of the Navy to be named for Hartford, Connecticut. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 30 June 1988 and her keel was laid down on 22 February 1992. She was launched on 4 December 1993 sponsored by Laura O'Keefe, wife of former Secretary of the Navy Sean O'Keefe, and commissioned on 10 December 1994, with Commander George Kasten in command.
USS Scranton (SSN-756), a Los Angeles-class submarine, is the second ship of the United States Navy to be named for Scranton, Pennsylvania.
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs.
The Naval Information Warfare Center Pacific, formerly the Space and Naval Warfare Systems Center Pacific, the Naval Command, Control and Ocean Surveillance Center (NCCOSC) RDT&E Division, the Space and Naval Warfare Systems Center San Diego, and the Naval Ocean Systems Center (NOSC), provides the U.S. Navy with research, development, delivery and support of integrated command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR), cyber and space systems and capabilities across all warfighting domains. The only Naval technical center headquartered in a major fleet concentration area, NIWC Pacific manages strategic locations both in the Pacific theater and around the world.
Unmanned underwater vehicles (UUV), also known as uncrewed underwater vehicles and underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input.
The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators.
Avenger-class mine countermeasures ships are a class of 14 ships constructed for the United States Navy from 1987 to 1994, designed to clear mines from vital waterways. The ships have the hull designator MCM.
The Lockheed Martin AN/WLD-1 RMS is a remotely controlled minesweeping system to be operated by surface warships. It consists of an unmanned semisubmersible vehicle, which tows a sonar array, and control infrastructure aboard the parent ship. The unmanned semisubmersible vehicle used is the US Navy Snorkeler-Class Unmanned Surface Vehicle.
Explorer autonomous underwater vehicle (AUV) is a Chinese AUV developed in the People's Republic of China (PRC), first entering service in November 1994. It should not be confused with another two Anglo-American AUVs that share the same name: the American Autonomous Benthic Explorer AUV (ABE) built by Woods Hole Oceanographic Institution, and the British Columbia-based International Submarine Engineering built Canadian Explorer AUV, which is based on its earlier ARCS AUV. Many Chinese AUVs later developed, such as Wukong, WZODA, CR series, Exploration series, Micro Dragon series, Sea Whale series, Submerged Dragon series AUVs, are all based on experienced gained from Explorer AUV.
The ASW Continuous Trail Unmanned Vessel (ACTUV) is a DARPA funded project launched in early 2010 to develop an anti-submarine drone. ASW is an acronym for Anti-Submarine Warfare. In January 2018 after successful sea trials it was announced that the "Sea Hunter" prototype has transitioned from DARPA to the Office of Naval Research for further development.
AUV - 150 is an unmanned underwater vehicle (UUV) being developed by Central Mechanical Engineering Research Institute (CMERI) scientists in Durgapur in the Indian state of West Bengal. The project is sponsored by the Ministry of Earth Sciences and has technical assistance from IIT-Kharagpur.
The Fleet-class unmanned surface vessel, also called the Common Unmanned Surface Vessel (CUSV) and later the Mine Countermeasures Unmanned Surface Vehicle, is an unmanned surface vessel designed for the United States Navy to be deployed from Freedom and Independence-class littoral combat ships and intended to conduct mine and anti-submarine warfare missions. As of 2012 four units of the class have been built; the first was delivered to the U.S. Navy in 2008.
The REMUS series are autonomous underwater vehicles (AUVs) made by the Woods Hole Oceanographic Institution and designed by their Oceanographic Systems Lab (OSL). More recently REMUS vehicles have been manufactured by the spinoff company Hydroid Inc, which was a wholly owned subsidiary of Kongsberg Maritime. Hydroid was acquired by Huntington Ingalls Industries (HHI) in March 2020. The series are designed to be low cost, they have shared control software and electronic subsystems and can be operated from a laptop computer. They are used by civilians for seafloor mapping, underwater surveying, and search and recovery as well as by several navies for mine countermeasures missions.
The SeaFox is an anti-mine Unmanned underwater vehicle (UUV) manufactured by German company Atlas Elektronik. It is designed to locate and destroy ground and moored mines. There are three versions, including a training version. The orange SeaFox-I "inspection" variant has sonar and an Inertial navigation system, and the black SeaFox-C "combat" round also has a 1.4 kilograms (3.1 lb) shaped charge warhead. The system is in service with eleven navies. The SeaFox is an advanced design of an Expendable Mine Disposal Vehicle or EMDV. It has a low life cycle cost as it has low running and replacement costs. Its main targets are sea mines that pose a danger to vessels. It communicates with the ship via a fiber-optic cable. The SeaFox uses a custom launch and retrieval system, that may be fitted to a variety of ships, boats or even helicopters. It can be used for a range of tasks such as conduct damage estimation, route surveys, maritime boundary control, intelligence and harbor surveillance missions.
The Knifefish is an autonomous unmanned underwater vehicle (UUV) under development by General Dynamics Mission Systems and Bluefin Robotics for the United States Navy. It is a propeller-driven minesweeping robot designed to replace the Navy's trained dolphins and sea lions after the retirement of the 50-year-old Marine Mammal Program in 2017. The Knifefish was first unveiled at a Navy exposition in April 2012, and was originally intended to operate in concert with the Navy's littoral combat ships (LCS) as part of a specialized counter-mine system.
Bluefin Robotics is an American robotics company, headquartered in Quincy, Massachusetts, which specialises in the design and manufacture of military and civilian autonomous underwater vehicles (AUVs) and related technology. The company was founded in 1997, and became a wholly owned subsidiary of Battelle Memorial Institute in 2005. Its products include the Bluefin-21 underwater search robot and its military derivative, the Knifefish minesweeping AUV, which entered service with the United States Navy in 2017. Bluefin was involved in the development of several advanced Navy projects, including the Black Pearl AUV and the Proteus optionally-manned submersible.
