Summary of the Article – Anti-submarine warfare technologies
1. Acoustics particularly in active and passive sonar, sonobuoys, and fixed hydrophones aid in the detection of radiated noise. Sonar can be mounted on the hull or in a towed array. High frequency radio direction finding (HF/DF or huff duff) is used to determine the bearings of U-boats.
2. Radar does not penetrate water, so finding subs from the air is usually a matter of dropping sonar buoys.
3. Passive sonar systems are used primarily to detect noise from marine objects (such as submarines or ships) and marine animals like whales.
4. Stealth submarines carry a radar reflector on the mast, making them visible on the navigation radars of other ships.
5. The most advanced U.S. submarines are nearly undetectable and can stay submerged for months.
6. A submarine at depth cannot be seen from afar, and radio waves fare poorly underwater.
7. Countries like the United States and China have built networks of hydroacoustic sensors to detect submarines.
8. Active sonar pulses can be transmitted at different frequencies and can provide range, bearing, and Doppler information on acoustic contacts.
15 Unique Questions
1. Can a ship detect a submarine? Acoustics in sonar systems and radio direction finding technologies aid in detecting submarines. Sonar can be mounted on the ship’s hull or in a towed array.
2. Can you detect submarines on radar? Radar does not penetrate water, so detecting submarines from the air typically involves dropping sonar buoys.
3. What device is used to detect submarines? Passive sonar systems are primarily used to detect noise from submarines, ships, and marine animals like whales.
4. Can stealth submarines be detected? Stealth submarines can be detected by other ships’ navigation radars because they carry a radar reflector on their mast.
5. How detectable are U.S. submarines? U.S. submarines, along with submarines from other countries like Russia, China, Britain, and France, are highly stealthy and can stay submerged for months.
6. Are U.S. submarines undetectable? Submarines at depth cannot be seen from afar, and radio waves do not perform well underwater, making underwater radar ineffective.
7. Are U.S. submarines detectable? Countries like the United States and China have built networks of hydroacoustic sensors to detect submarines near their coastal borders and strategic military locations.
8. How far can sonar detect submarines? Active sonar pulses can be transmitted at multiple frequencies and can provide range, bearing, and Doppler information on acoustic contacts at depths of up to 457 meters (1,500 feet).

Can stealth submarines be detected
They can also be considered stealth ships — albeit unintentionally. That's why they carry a radar reflector on the mast — an octahedron made out of plated metal. This way the the ship becomes visible on the navigation radars of other ships.
How detectable are U.S. submarines
The world's deadliest weapons are also the stealthiest. The United States, Russia, China, Britain, and France all have fleets of submarines that carry nuclear missiles. The most advanced of these subs are nearly undetectable and can stay submerged for months.
Are U.S. submarines undetectable
A submarine at depth cannot be seen from afar—daylight is all but undetectable at depths of more than a couple of hundred metres. Radio waves fare even worse, making underwater radar a non-starter.
Are U.S. submarines detectable
Countries like the United States and China have built networks of hydroacoustic sensors, which use sonar technology to detect submarines that navigate close to their coastal borders and strategic military locations.
How far can sonar detect submarines
Active sonar pulses can be transmitted at four frequencies (6.5 kHz, 7.5 kHz, 8.5 kHz, and 9.5 kHz) and can operate for up to one hour at depths of up to 457 m (1,500 ft). The echo returns of the active sonar signals provide range, bearing, and Doppler information on acoustic contacts.
Can active sonar detect submarines
Navy Sailors use sonar to detect submerged objects such as submarines and mines. The ocean can be a very noisy place, full of sounds from natural sources like marine animals, breaking waves, rain, lightning, and earthquakes, to man-made sources like ships and seismic exploration.
Can the US detect enemy submarines
Countries like the United States and China have built networks of hydroacoustic sensors, which use sonar technology to detect submarines that navigate close to their coastal borders and strategic military locations. Map of hydroacoustic monitoring stations in the CTBTO's international monitoring system (IMS).
How far can sonar detect a submarine
The detection range is from 10 to 2400m (divided into 15-steps) and there are two types of Sonar: Single Frequency Sonar and Dual Frequency Sonar. The hull unit, with a travel range of 25 to 40 cm, is installed at the bottom of the vessel.
At what depth are submarines undetectable
A submarine at depth cannot be seen from afar—daylight is all but undetectable at depths of more than a couple of hundred metres. Radio waves fare even worse, making underwater radar a non-starter.
Why is it so hard to detect a submarine
Salt water is mostly opaque to electromagnetic radiation, so subs are invisible to radar. Sonar can locate underwater objects, but modern submarines are built to be very quiet.
Can submarines hide from sonar
Submariners can find places between the bending sound waves of active enemy SONAR called shadow zones. There, subs can hide and watch the enemy without being detected. Modern control systems enable a submarine to operate much like an airplane, but subs fly in a sea of water.
Are US submarines undetectable
Salt water is mostly opaque to electromagnetic radiation, so subs are invisible to radar. Sonar can locate underwater objects, but modern submarines are built to be very quiet.
Can Russian submarines be detected
"If a modern nuclear submarine dives and settles on the seabed to hide and wait, it is almost impossible to detect except if you happen to actively pinging it just on the right spot with an active sonar," Pöyry said.
Can submarines avoid detection
And whales they must take action that usually involves turning the sonar down or off completely the way sound waves Bend determines. What can be picked up by sonar submariners can find places between
What is the deadliest submarine in the world
Thank you attack submarines a vital component of Naval Warfare are built with one goal in mind. The destruction of enemy ships. The number of countries with submarine fleets has increased to at least
Has a submarine ever killed another submarine
German submarine U-864 was a Type IXD2 U-boat of Nazi Germany's Kriegsmarine in World War II. On 9 February 1945, she became the only submarine in history to be sunk by an enemy submarine while both were submerged. U-864 was sunk by the British submarine HMS Venturer, and all 73 men on board died.
What is the deepest a submarine can go in the ocean
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world's oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
What’s the deepest a submarine has gone
Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres (35,797 ft) in the Challenger Deep of the Mariana Trench near Guam in the Pacific.
What is the longest a submarine has stayed submerged
111 days
What is the Longest a Submarine Has Stayed Submerged The longest a submarine has ever stayed submerged is 111 days.
How many submarines are in the ocean right now
The Submarine Force is Comprised of More Than 70 Submarines.
In today's Naval Submarine Force, there are 53 fast attack submarines, 14 ballistic missile submarines – which currently carry more than 54% of the U.S.' nuclear deterrent arsenal – and four guided-missile submarines.
How many submarines are lost in the ocean
Nine nuclear submarines have sunk, either by accident or scuttling. The Soviet Navy lost five (one of which sank twice), the Russian Navy two, and the United States Navy (USN) two.
How far can a submarine go down before being crushed
It's generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675–900m (2,250–3,000 ft).
