How can missiles work underwater?

Flight Profile of Tomahawk Missile Tomahawk missiles can be launched from either a standard 21-inch (53-cm) torpedo tube or, on newer submarines, a vertical launch tube. After the missile clears the submarine, a 7-second burst from its rocket boost motor blasts it out of the water.

When fired, a missile is ejected from the submarine by high pressure gas and only when it breaks the surface does the first rocket stage actually fire. Then the missile’s own inertial guidance system takes over, calculating actual flight behaviour and guiding it to a pre-determined point in space.

torpedo, cigar-shaped, self-propelled underwater missile, launched from a submarine, surface vessel, or airplane and designed for exploding upon contact with the hulls of surface vessels and submarines.

A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads.

Spin they do, but not necessarily at the same speed as a bullet; nor for very long. In the case of rockets, the “spin” is really a roll program, and is part of the maneuver to get the rocket headed the way you want it to go. Thus we see it early after launch, but it frequently stops further along the flight path.

Starting a rocket while submerged technically allows the vehicle to start moving upwards from the positive buoyancy, by dumping ballast getting lift for ‘free’. On the other hand a vehicle starting on land doesn’t need to do anything to reach sea level to start with.

Currently, all submarines launch SLBMs while submerged, at various shallow (CLASSIFIED) depths. The Russians can also launch on the surface.

Endurance: Nuclear submarines can operate underwater for three or four months at a time and cross oceans with ease.

Nuclear-Weapon States: The nuclear-weapon states (NWS) are the five states—China, France, Russia, United Kingdom, and the United States—officially recognized as possessing nuclear weapons by the NPT.

missile launching systems Submarine-launched ballistic missiles (SLBMs) are ejected in this manner to the ocean surface from tubes within the submerged vessel.

Well,for starters,we know that Harpoon guns work really well underwater. This thing can be easily repurposed for underwater warfare due to the fact that It is well-suitted for underwater use. Another weapon that can be used underwater is the APS Assault rifle,or as I like to call It ‘Underwater Kalashnikov’.

BrahMos is the world’s fastest cruise missile.

In flight, the fins of the rocket produce aerodynamic forces. … The torques cause the rocket to rotate. Most full scale rockets produce pitch or yaw motions by gimballing, or rotating, the exhaust nozzle. If the thrust vector is not alligned with the roll axis, it produces a torque about the center of gravity.

Rifling helps impart a spinning motion to a bullet when it’s fired. A spinning bullet is much more stable in its trajectory, and is therefore more accurate than a bullet that doesn’t spin. … How does the spin make the flight of a bullet more stable? By Angular Momentum or gyroscopic inertia.

A rolleron is a type of aileron used for rockets, placed at the trailing end of each fin, and used for passive stabilization against rotation. Inherent to the rolleron is a metal wheel with notches along the circumference. … During flight, this will spin the wheels up to a substantial speed.

The Sea Dragon never made it out of the concept stage in the 1960s. It was not needed for anything that either NASA or the military was doing in space at the time. The Saturn V was quite sufficient for the moon program.

To keep costs low, Sea Dragon was designed to be built from inexpensive sheet steel, launched from the ocean to reduce launch infrastructure, and operate using simple, reliable engineering principles.

Missiles are powered by an engine, generally either a type of rocket engine or jet engine. Rockets are generally of the solid-propellant type for ease of maintenance and fast deployment, although some larger ballistic missiles use liquid-propellant rockets.

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.

This usually provides the guidance that a rocket needs during atmospheric flight, where hypergolic thrusters or reaction wheels cannot be fully effective. This allows the thrust of the rocket’s engines to be pointed in different directions, which would allow the rocket to change its direction.

For cyber-security reasons, the military generally prohibits personal use of military computers and networks. Computer equipment and networks for morale, welfare and recreation (MWR) are isolated from the systems required for the mission. There would be NO allowed personal use of wi-fi or bluetooth within a submarine.

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. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.

No one can smoke on US submarines because it’s been prohibited since December of 2010.

It killed about 80,000 people when it blew up. When the Japanese didn’t surrender after the “Little Boy” bomb destroyed Hiroshima, President Truman ordered that a second atomic bomb, called “Fat Man”, be dropped on another city in Japan.

Atom or atomic bombs are nuclear weapons. Their energy comes from reactions that take place in the nuclei of their atoms. During World War Two, “atomic bomb” usually meant a bomb that relies on fission, or the splitting of heavy nuclei into smaller units, releasing energy.

It is made up of four nuclear submarines. Each sub carries up to eight missiles on board, and each missile carries up to five nuclear bombs – or warheads – on top. Each of these bombs is around eight times as destructive as the bomb which flattened Hiroshima in 1945, killing over 140,000 civilians.

US submarines carry a small number of firearms for the officers, senior NCOs and the small number of enlisted sailors whose battle station duties including guarding the vessel and/or its weaponry. These are stored in the ship’s tiny armory and they are rarely withdrawn (it’s a LOT of paperwork if they get used). Yes.

It’s fired by a steam cannon. First, an explosive charge flash-vaporizes a tank of water into steam. As the pressure of the expanding steam drives the missile out of its launch tube, it provides enough momentum for the weapon to clear the water’s surface.

How firing an AK47 underwater can actually make it work BETTER: Enthusiast proves not only does weapon fire while submerged, it reloads faster. Submerging an AK 47 gun and firing it underwater appears to make it work better, according to high speed footage.

Fires can’t burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.

Depending on the type of gun, it is possible to fire underwater. … There are some pretty common things that happen to guns underwater. Water causes issues with the ammunition, the action, and the projectile ballistics. Once you get your gun underwater, the barrel almost immediately fills up with water.

Basic weight is about 700 pounds (320 kg), although the weights of individual weapons may vary depending on version and fuze/retardation configuration. As of 2020, it is undergoing a 12th modification. According to the Federation of American Scientists in 2012, the roughly 400 B61-12s will cost $28 million apiece.

Development and acquisition. In August 2018, the U.S. Air Force awarded a $480 million contract to Lockheed Martin for the development of an air-launched hypersonic weapon. The resulting missile, the AGM-183A ARRW (“Arrow”), underwent an initial captive carry flight test aboard a U.S. Air Force B-52 in June 2019.

But it has to be remembered that the SR71 was a spy plane, it didn’t need offensive capabilities and its stealth, ability to outrun missiles, and high altitude capabilities were defense enough.

Former Russian/Soviet submarines have been offered for sale. A decommissioned Whiskey Class submarine was offered for sale online at: Vessel for Sale PI12 , and is currently listed as “sold.”

The U.S. military’s latest assessment of Chinese military power, published in September 2020, estimated that China had 50 diesel-powered attack submarines, six nuclear-powered attack submarines and four nuclear-powered ballistic missile submarines. … China’s submarine fleet serves another important strategic function.
