Railgun Uss Zumwalt - Zumwalt-class destroyers still have ammunition, but the US Navy has an idea, or at least the beginning of an idea.
The Navy has invested hundreds of millions of dollars and more than a decade in rail research, which has run into several technological barriers. But while rail may not become a major project, rail transit seems to show promise.
Railgun Uss Zumwalt
The Navy fired up to two hypervelocity bombs (HVP) — special rounds originally designed for electromagnetic railguns — from the Mk 45 5-inch gun on the Arleigh Burke-class destroyer USS Dewey during the Pacific Rim of last year (RIMPAC) ). ) exercise, USNI News first reported. Guns and guns have been coming standard for ships and destroyers for 40 years.

The same concept can be applied to the 155 mm Advanced Gun System (AGS) on the Zumwalt-destroyer. "That's one thing that's been considered in terms of the capabilities of this class of ship. We're looking at a long-term project that's affordable, so that's one thing that's being considered," said Captain Kevin Smith, director of the Zumwalt Company. at the Surface Navy Association symposium, USNI News reported Tuesday.
This is obviously only one possibility. "There are a lot of things we're looking at as far as deep magazines that have other types of weapons that go farther," Smith explained. Early ideas included a Raytheon Excalibur 155 mm guided gun, but that plan was abandoned.

The Zumwalt 155mm AGS gun, which is designed to attack at a range of more than 80 miles, is very expensive to fire, as one Long Range Land Attack Projectile costs about $1 million. The acquisition closed two years ago, leaving Zumwalt without ammunition.
The Navy "will develop a gunship or what we will do in that position if we decide to remove that gun in the future," Vice Adm. William Merz, deputy director of naval operations at war. system, he told the Senate Judiciary Committee in November, Breaking Defense reported at the time.
So, if the Navy can't find the right ammunition for the destroyers to steal, it can get rid of the gun altogether to replace it with something else down the road.
The Zumwalt Destroyer Is Here, Now What About The Railgun?
Despite numerous failures, including everything from loss of privacy to engine and electrical problems, the Navy insists "the ship is in good working order." Merz told Congress that the ship should be operational by 2021. In the past, ships have used multiple thrusters to propel them, with motors and engines that connect directly through large, rigid shafts. But all Zumwalt electric boats will come equipped with what's called an "Induction Power System (IPS)," designed to connect the electrical system around the boat in an instant, eliminating the need for machinery and allowing power to be used for both propulsion and other electrical systems. . system - including powerful new weapons.
It will have almost 10 times more power available than its predecessor. It may be the first ship to be armed with future weapons such as an electromagnetic railgun, which uses powerful electromagnetic pulses, rather than gunpowder, to fire bombs.
IPS can release up to 80 percent of the boat's rated power in a fraction of a second. "We don't limit the engine to just providing propulsion," says Adam Kabulski, marine account manager at Power Conversion, which developed the IPS. "This design allows you to send electrical energy wherever you need it. You can get a lot of megawatts in a short amount of time and turn it into energy. It's instantaneous."
The system is also redundant. Instead of a conventional three-phase motor, the "Zumwalt" advanced motor" has 15 phases. "The design is new, smaller and quieter than a traditional motor, and also more durable," says Kabulski.

The IPS, which supplies power at 4, 160 volts, also has integrated filters, electronic devices and other technologies to maintain the quality of the electricity and electrical disturbances that do not spread in the system.
These powerful steering forces give boat designers many options. The US Navy recently announced that the Navy is considering a third electromagnetic train for the planned Zumwalt-class destroyer, the USS Lyndon B. Johnson.
According to military.com, the weapon can release up to 5 million amps, or 1,200 volts in 10 milliseconds. That's enough to propel a 45-pounder from zero to 5,000 mph in one hundred-seconds, the website said. "Special weapons, like the EM rail, are the future of naval warfare," said Rear Adm. Matt Klunder, director of naval research.
The Navy said it plans to test-fire a series of GPS-guided missiles from a gun mounted on a speedboat on a floating barge up to 50 miles away. US Navy program director Mike Ziv told military.com "We're going to shoot it on a floating cage," he said. "We're trying to measure the ability to engage over the horizon. We'll be slowly gathering data." Exams are scheduled for spring 2016.

Has been providing power distribution technology for centuries. The Navy's first electric ship, the aircraft carrier USS Jupiter, was commissioned in 1913.

The Office of Naval Research's EMRG program is part of the Department of the Navy's science and technology investment, focused on the development of new technologies to support the needs of naval and naval warfare.

BATH, Maine — The development of a futuristic weapon seen in video games and science fiction is going so well that the head of the Navy wants to jump ship a prototype to install a nuclear-powered unit expected to enter service in 2018.
The Navy has been testing an electromagnetic railcar and may have a manufacturing unit ready to go into one of the new Zumwalt loudspeakers under construction at the Bath Iron Works.
Adm. Navy Admiral Pete Fanta has suggested abandoning the current plan to put the prototype on another ship this year and putting it directly on the future USS Lyndon B. Johnson, though no final decision has been made. done. .
Navy Matters: Zumwalt Status Update
Lt. "The Zumwalt class is one of many different types of railguns that are being researched," he said. Cmdr. Hayley Sims, a Navy spokeswoman. "Due to size, weight and power requirements, some sites will be more suitable for the technology than others."
The future USS Zumwalt (DDG 1000) continues on December 7th for the first time conducting tests and sea trials in the Atlantic. The multi-mission ship will provide independent frontline and deterrence, support special forces, and serve as an integral part of the combined force.
A rail gun uses electricity instead of powder to accelerate the projectile to six or seven times the speed of sound – creating enough kinetic energy to destroy a target.
It's a typical whiz-bang technology that has the potential to deliver better weapons for the dollar than smart bombs and missiles.

Ever since the Zumwalt program began it has been rumored that the destroyer could be a potential weapon candidate for the power plant. The USS Johnson will be the third and final destroyer in the Zumwalt class.
The 600-meter-long warship uses marine turbines similar to Boeing 777 propellers to help generate up to 78 megawatts of electricity for propulsion, weapons and sensors. That's more than enough juice for the train.
When deployed on the battlefield, the system can replace one of the front warheads which includes a 155mm gun that fires artillery shells.
