Sonar is a technique that uses sound propagation to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.
K-222 was the sole Project 661 "Anchar" nuclear-powered cruise-missile submarine of the Soviet Navy during the Cold War. Although the Soviets saw K-222 as an unsuccessful design, upon completion it was the world's fastest submarine and the first to be built with a titanium hull.
The Spearfish torpedo is the heavy torpedo used by the submarines of the Royal Navy. It can be guided by wire or by autonomous active or passive sonar, and provides both anti-submarine warfare (ASW) and anti-surface warfare (ASuW) capability. Spearfish development began in the 1970s, with production starting in 1988, and deployment in 1992. By 2004, the new weapon had completely replaced the older Tigerfish torpedo.
The Naval Undersea Warfare Center (NUWC) is the United States Navy's full-spectrum research, development, test and evaluation, engineering and fleet support center for submarines, autonomous underwater systems, and offensive and defensive weapons systems associated with undersea warfare. It is one of the corporate laboratories of the Naval Sea Systems Command. NUWC is headquartered in Newport, Rhode Island and has two major subordinate activities: Division Newport and Division Keyport in Keyport, Washington. NUWC also controls the Fox Island facility and Gould Island. It employs more than 4,400 civilian and military personnel, with budgets over $1 billion.
Rona, sometimes called South Rona to distinguish it from North Rona, is an inhabited island in the Inner Hebrides. It lies between the Sound of Raasay and the Inner Sound just north of the neighbouring island of Raasay and east of the Trotternish peninsula of Skye. It has a total area of 930 hectares (3.6 sq mi) and a population of 3.

USS Tigrone (SS/SSR/AGSS-419), a Tench-class submarine, was the only ship of the United States Navy to be named for the tigrone, a tiger shark found in tropical waters. Her keel was laid down on 8 May 1944 by the Portsmouth Navy Yard. She was launched on 20 July 1944 sponsored by Mrs. Mary B. Grisham, wife of Captain Charles F. Grisham, USN, Superintendent of the Portsmouth, N.H., Navy Yard, and commissioned on 25 October 1944.
Thales Underwater Systems or TUS is a subsidiary of the French defense electronics specialist Thales Group. It was created in 2001 and belongs to its naval division. It specializes in the development and manufacturing of sonar systems for submarines, surface warships and aircraft, as well as communications masts and systems for submarines. Its headquarters are located in Sophia Antipolis, France.
A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low noise-emitting submarine threats, or seismic signals.
The Inner Sound is a strait separating the Inner Hebridean islands of Skye, Raasay and South Rona from the Applecross peninsula on the Scottish mainland. The Inner Sound is the location of BUTEC, a Royal Navy submarine sensor and emissions range.
The Canadian Forces Maritime Experimental and Test Ranges (CFMETR) is a maritime test facility located on the east side of Vancouver Island, at Nanoose Bay.
Anti-submarine warfare is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades.
The Type 039 submarine is a class of diesel-electric submarines of the People's Liberation Army Navy. The class is the first diesel-electric submarine to be made in China and also the first Chinese made diesel-electric submarine to use the teardrop hull shape. Altogether thirteen vessels were completed to the Song Class design between 1999 and 2006, with three variants as the type developed.
The Naval Physical and Oceanographic Laboratory or NPOL is a laboratory of the Defence Research and Development Organisation (DRDO), under the Ministry of Defence, India. It is situated in Thrikkakara, Kochi, Kerala. NPOL is responsible for the Research & Development of sonar systems, technologies for underwater surveillance, study of ocean environment and underwater materials.
The United States Navy's Atlantic Undersea Test and Evaluation Center (AUTEC) is a laboratory that performs integrated three-dimensional hydrospace/aerospace trajectory measurements covering the entire spectrum of undersea simulated warfare – calibration, classifications, detection, and destruction. Its mission is to assist in establishing and maintaining naval ability of the United States through testing, evaluation, and underwater research.
Sonar technician is a United States Navy occupational rating.
Luce Bay is a large bay in Wigtownshire in southern Scotland. The bay is 20 miles wide at its mouth and is bounded by the Rhins of Galloway to the west and the Machars to the east. The Scares are rocky islets at the mouth of the bay.
The SACLANT ASW Research Centre was the predecessor to the NATO Undersea Research Centre. It was known as The SACLANT ASW Research Centre from 1959 through 1986, and the SACLANT Undersea Research Centre from 1987 through 2003. The centre was commonly referred to as SACLANTCEN.
The Deep Sea Range is an RAF missile range in the Outer Hebrides. It has also been known as the Hebrides Guided Weapon Range and the South Uist Missile Range.
The Taigei-class submarines (29SS) (Japanese: たいげい, "Big Whale") is a new class of attack submarines after 2022, developed for the Japan Maritime Self-Defense Force. It is the successor to the Sōryū class.
