A submarine at crush depth is subject to forces of such intensity that it will be crushed. This is due to the increased pressure and force exerted by the water in its environment. As the submarine descends deeper into the sea, the pressure increases exponentially.
The outer hull of the submarine must be strong enough to resist the force without buckling. If the sub is unable to do so, it will collapse and deformation will occur. Eventually, the outer hull will buckle under the immense pressure and the submarine will be crushed.
Inside the submarine, the crew may experience a rapid increase in pressure and temperature as the water compresses the air within the vessel. As the outside pressure increases, the air inside will become harder to breathe and the temperature will rise dramatically.
This can lead to an array of medical issues for the crew, including the bends, an often fatal decompression sickness caused by a rapid change in pressure.
What is the maximum crush depth of a submarine?
The maximum crush depth of a submarine depends on the class and materials used to construct it. Submarines are generally designed with an operating depth of 2,000-2,500 feet (610-762 m) with a maximum or crush depth of around 3-4 times the operating depth.
For example, for a deep-diving submarine operating at a depth of 2,000 feet, the crush depth could be 6,000-8,000 feet (1,830-2,440 m). However, some of the most advanced submarines designed today have an operating depth of over 6,000 feet (1,830 m) and a maximum crush depth of up to around 24,000 feet (7,300 m).
What happens to humans when submarine implodes?
When a submarine implodes, the effects on humans depend on the depth of the implosion and the severity. In the event of a shallow implosion, the pressure of the imploding hull could cause irreparable damage to the crew, resulting in serious injuries or death.
If the submarine imploded at a deeper level, the immense pressure of the surrounding water would be far greater and the effects could be catastrophic. The high pressure would cause rapid compression of the air contained within the submarine, and any survivors would likely suffer from extreme decompression sickness.
The sudden and rapid decrease in pressure would cause dissolved gases to come out of solution and form bubbles, leading to severe tissue damage, gas emboli, and systemic failure. In the worst-case scenarios, survivors could suffer embolisms, cardiac arrest, complete loss of consciousness and possibly fatal fatalities.
Due to the high pressure and implosion of a submarine, it is difficult to survive, and implosions are some of the most dangerous incidents a submarine can face. Any survivors are likely to suffer from severe trauma, along with physical and psychological injuries.
What is the longest a submarine has stayed submerged?
The record for the longest a submarine has stayed submerged belongs to the Russian Navy. The crew of the K-162, a Soviet aluminum-hulled deep-submergence vessel, took their sub to a depth of 3,000 meters and stayed submerged for an astounding 645 days.
The historic voyage began on 2nd December 1969, during the Cold War, and lasted until 23rd August 1971. During this time, the crew of the submarine survived on rations of 30 grams of bread and 10 grams of oatmeal each day.
The submarine was part of the Soviet fleet that patrolled the waters around the world reporting on underwater activity to the Navy. The K-162 was decommissioned after their record-breaking, two-year voyage and is currently moored at a Russian submarine museum.
Can you survive a tsunami in a submarine?
Yes, it is possible to survive a tsunami in a submarine. Submarines are designed to be able to withstand changes in underwater pressure, which makes them suitable for underwater survival. The submarine can be submerged to depths of hundreds of metres and the pressure will equalise with the outside water pressure to maintain a stable environment.
Submarines also have several other features that can help them survive. They are equipped with robust sonar systems which detect any incoming tsunami waves and give the crew time to prepare for the potential impact.
They also have a hull made of high-strength steel which can absorb the force of a tsunami and help protect the crew. Additionally, submarines have stabilising systems which can be used to maintain control during turbulent waters.
Finally, because submarines are manoeuvrable, they can quickly avoid any large underwater objects or debris brought by the tsunami. All these features can help submarines survive a tsunami.
Has a submarine ever reached the bottom of the ocean?
Yes, submarines have reached the bottom of the ocean. The first-ever deep-sea expedition was the Trieste dive made in 1960. This historic dive was taken by Don Walsh and Jacques Piccard and descended 35,800 feet (10,911 meters) into the Mariana Trench in the Pacific Ocean.
Since then, other submarines have attempted and achieved deeper dives into the abyss.
The deepest known manned submarine dive is the DEEPSEA CHALLENGER dive taken in 2012, which descended 35,853 feet (10,927 meters). The submarine was piloted by the well-known director James Cameron. This dive set the record for the deepest solo dive by a human and the first solo dive to the bottom of the ocean.
In addition, many unmanned submarines have reached even greater depths. The deepest recorded dive by an unmanned submarine is currently held by the Kaiko, which descended 37,000 feet (11,232 meters) into the Mariana Trench in 1995.
This robotic submarine recorded a variety of images and readings during its dive, providing scientists with invaluable data about the ocean floor.
Though no dive has ever exceeded the depth of the DEEPSEA CHALLENGER dive, submarines have been instrumental in providing us with an understanding about the depths of the ocean. Through these incredible expeditions, we are able to gain knowledge about the world beneath the sea and learn more about marine life and its habits.
How deep can US nuclear subs dive?
The depth that US nuclear submarines can dive is classified information, but generally speaking, it is believed that nuclear submarines are capable of diving to depths of up to 1000m (3,280 feet). This is deep enough to avoid detection by many other vessels and avoid interference from shallower objects and shoals.
Nuclear submarines are designed to be able operate in the depths of the ocean, both to avoid detection and to detect other vessels. They are also designed to be able to travel underwater for months at a time if necessary.
Can a shark bite a submarine?
No, a shark cannot bite a submarine. Sharks are large, powerful predators, but they do not have the strength or bite force to puncture a submarine. Submarines are designed to be able to withstand great depths and strong pressures encountered in the ocean, and a shark’s bite force isn’t powerful enough to be able to penetrate their thick hulls.
Also, the metal and other materials that submarines are made of are too hard for the teeth of a shark, so even if a shark was able to swim close enough to nibble at the hull of a submarine, it would not have the capability to cause any significant damage.
How do submarines not hit whales?
Submarines have a variety of tactics for avoiding collisions with whales. They typically use their sonar systems to detect the presence of such large aquatic animals and alter their course accordingly.
Sonar technicians onboard the submarine are also tasked with manually scanning the water and looking for whales. Additionally, submarines employ a form of passive sonar which ‘listens’ to the sounds created by whales and other aquatic animals.
In some cases, submarines also ‘ping’ the water with a sound of their own to alert whales of their presence and encourage them to move away. When in the open ocean, submarines are known to travel and surface together in groups in order to reduce the risk of a collision.
Specialized submarine trained crewmembers, called lookouts, scan the horizon for any approaching objects that could potentially cause a collision. If a whale is observed and a collision is imminent, submarines can also deploy water jets to create a powerful thrust of water which can push the whale away.
What’s the deepest a Navy submarine has gone?
The deepest a Navy submarine has ever gone is 8,375 meters, or 27,480 feet. This happened during the Mariana Trench Expedition in June 2019, when the U. S. Navy submarine USS San Francisco, a Seawolf-class fast-attack submarine, descended to the bottom of the Mariana Trench in the western Pacific Ocean.
During the 16-hour mission, the submarine’s crew members collected data and observed creatures living in the deepest part of the world’s oceans. The ship’s deep-diving capabilities helped the crew observe the environment and its inhabitants in ways never before possible.
This deep-dive capability was made possible by the advanced engineering design of the USS San Francisco submarine and its robust array of sensitive instruments.
How deep can a submarine go before being crushed?
The maximum depth a submarine can reach before being crushed depends on the different materials used in its construction and the level of technology involved. Most modern-day submarines have been designed to withstand the pressures of depths up to 2,000 meters (6,560 feet).
However, the most advanced submarines are capable of reaching depths of at least 4,800 meters (15,700 feet).
It is important to note though, that despite being built to resist the huge pressures of incredible depths, there is still a limit as to how deep a submarine can safely go. To prevent being crushed by the immense pressures, submarine hulls are typically built with great strength and a number of safety systems in place to protect the crew.
To provide additional protection, submarines incorporate buoyancy control systems and other innovative technologies. These help to provide the necessary stability and buoyancy to remain mobile in the depths and avoid the crushing forces of the surrounding water.
Ultimately, the depth a submarine can reach is dependent on a variety of factors and is constantly in a state of improvement. As technology continues to advance and submarine designs become more sophisticated, submarines will be able to reach greater depths safely.
How fast do submarines go?
The speed of a submarine can vary greatly depending on various factors such as the type of submarine, its overall design, the type of propulsion system it is using, and the payload it is carrying. Generally speaking, the average speed of a modern submarine is around 20 knots (23 mph) while submerged, with some capable of reaching speeds up to 35 knots (40 mph).
The speed of a submarine can also be increased or decreased depending on its depth. For example, most submarines can travel faster while on the surface since there is less water resistance; however, as a submarine dives deeper, the amount of water resistance increases, making it more difficult for the submarine to achieve higher speeds.
There are also specific classes of submarines that are designed to have much higher speeds than the average submarine. For instance, some high-speed submarines may have the ability to reach up to 50 knots (58 mph) while submerged.
What was the last US submarine to sink?
The last U. S. submarine to sink was the USS Bullhead (SS-332). The Japanese warship, I-58, sank the Bullhead on March 3rd, 1945 in the South China Sea about 70 miles south of Anambas Islands. All 73 enlisted men and officers on board were reportedly killed in the attack.
The Bullhead was a Balao-class submarine built during World War II and commissioned on January 20th, 1944. She was the first Balao-class submarine lost in combat during the war. The Bullhead was involved in six war patrols during her operational history and is credited with sinking seven Imperial Japanese Navy vessels.
Why depth charges don’t have to touch a submarine to sink it?
Depth charges don’t have to touch a submarine to sink it because they rely on the shockwave created by their explosive force to destroy or damage the vessel. The shockwave moves outward from the detonation point and creates a powerful pressure wave which can cause extensive damage to a submarine’s hull, resulting in flooding of the vessel and eventual sinking.
Additionally, the pressure wave can cause disruption to the submarine’s systems and equipment, leading to a loss of control and further increasing the risk of sinking. As the length and strength of the shockwave is determined by the size of the explosive, larger depth charges can have greater impact over longer distances, allowing them to sink targets without making direct contact.
How deep could a WWII submarine dive?
Typical World War II-era submarines were capable of diving to depths of around 300 feet (90 m). Submarines built after the war were generally capable of diving deeper—some could submerge to depths of over 900 feet (275 m).
The deepest-diving submarines were capable of reaching depths of up to 1,500 feet (460 m), though this was a dangerous depth, as it put tremendous strain on the vessel and its crew.
