Why was the submarine invented?
Perhaps the most successful early submarine was designed by American inventor Robert Fulton. He lived in an age of naval battles, but hated war. Fulton hoped that a device that could make warships ineffective would end war altogether.
What makes submarines different from submersible?
The difference between a submarine and a submersible is a submarine has enough power to leave port and come back to port under its own power. A submersible has very limited power reserves so it needs a mother ship that can launch it and recover it.
What is the most likely to limit how long a modern submarine can remain submerged?
The only factor limiting the amount of time that a submarine can remain submerged is the amount of food and water that it can carry. Even Bishop John Wilkins, when he imagined the military capabilities of future submarines in 1648, could not have dreamed of such an amazingly powerful watercraft.
Do submarines have the best food?
When a submarine leaves on patrol, food fills every available corner. Eating takes place in the crew’s mess. Despite the tight galley space, good meals are the rule, with the same menu for officers and enlisted men. Extra funding for food makes submarines the best “feeders” in the Navy.
Has a submarine ever hit a whale?
It can be quite spectacular sometimes. It happens on rare occasions. Whales make sounds that can be heard by the submarine sonar. Submarines usually try to avoid the whales, but on the rare occasions that a collision occurs, it is the whale that suffers the worst of it.
Is a submarine faster than a ship?
A submarine can be faster than a boat. Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr).
How deep can a torpedo go?
| Mark 48 torpedo | |
|---|---|
| Propellant | Otto fuel II |
| Maximum depth | 500 fathoms, 800 m (2,600 ft) (estimated), officially “greater than 1,200 ft” |
| Maximum speed | 55 kn (63 mph; 102 km/h) (estimated) officially “greater than 28 kn (52 km/h; 32 mph)” |
| Guidance system | Common Broadband Advanced Sonar System |
Can a sonar ping kill you?
Yes, it can kill you if you are close enough. The U.S. Navy’s sonar emits 235-decibel pressure waves of unbearable pinging and metallic shrieking. At 200 Db, the vibrations can rupture your lungs, and above 210 Db, the lethal noise can bore straight through your brain until it hemorrhages that delicate tissue.
How fast can a torpedo go underwater?
The British Spearfish torpedo designed to counter high-speed Russian submarines, such as the Alfa-class submarine, is reputed to have a speed in excess of 70 knots (130 km/h). The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h).
Can a torpedo sink an aircraft carrier?
During World War II, submarine and aircraft-dropped torpedoes sank hundreds of merchant ships and warships. Unlike the numerous aerial bombs or cannon shells required to sink large warships, just one or two torpedo hits could and sometimes did suffice to sink huge aircraft carriers and battleships.
Could a submarine survive a tsunami?
Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. Large enough waves can cause a submarine to be pulled (sucked) up to the surface.
Could you survive an asteroid impact in a submarine?
2. The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.
Why does the ocean pull back before a tsunami?
Why does the water level drop before the tsunami hits? Because it is like a tide, the tide goes out before it comes in. As the tsunami approaches water is drawn back from the beach to effectively help feed the wave.
Can you live on a submarine?
CRAMPED, ISOLATED, AND HEAVILY-ARMED: What Life Is Like On A US Navy Submarine. US Navy With deployments underwater typically running 90 days, life onboard a submarine is anything but normal. Of course, even once qualified, serving aboard a submarine is not a walk in the park.
Do submarines have AC?
Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.
How deep can submarines go in the ocean?
about 300m
Can you legally own a warship?
Yes you can legally own a functioning Battleship. The thing with a Battleship or multiple gun machine is that each gun on it would have to be Tax Stamped or disabled.
Is it illegal to buy a submarine?
“When a submarine is on the surface, it’s the same like another ship,” van Eijk said. There are no specific legal restrictions on civilian subs anywhere in the world.
How much is the cheapest submarine?
The costliest personal submarine in the SportSub collection is priced over US$ 5, 00,000 while the cheapest is priced at around US$ 30,000.
Can I buy a military submarine?
Sure. You can build and operate as large as a submarine as you can afford. It would not be legal to in the US to operate it as a warship and obtain weapons for it, as those weapons would not be legal. The catch with most tourist subs is that they can only dive to a few tens of meters.
