Navy rail gun shooting multiply shots

a reply to: seagull

do you research

a reply to: dragonridr

one gun at ten rounds per mimute non stop would take 20 megawatts.. so that leaves zummelt and carriers.. but they have a way of just using batteries so are large landing craft with big cargo bay coukd hols enough juice for say 50 shots.

any breakthrough in power production will remove many of the limits on railguns and lasers.

and for those wonderimg they almost moumted this railgun on a navy boat in 2016 for open water testing.. they decided no to this to save money and now they are considering skipping a prototype testing phase and possibly just go live aboard a zummelt in 2018.

sounds like they are excited to put this program into action ASAP

@buddha.. Lol... you have got to be kidding me.

and as far as "line of sight weapon?" i dont know whete that other poster is getting that.. its a ballistic projectile.. it shoots 100 miles.. The horizon is like 3 miles away maybe 4 or 5 at tbe height of the gun..

so you know just let that sink in.. youd have to be at least 6700 feet up in the air to see what you are hitting at 100 miles.

thats line of site.. so a laser being a line of site weapon youd need 6700 feet altitude to shoot the same distance..

ballistic trajectories can shoot "over the horizon"

gotta love the Rail Gun, also no risk of explosions due to ammo storage if it's purely a Kinetic round.

The power of that thing ! make the round out of depleted uranium then that would be quite evil.
Though the power it has its hardly significant really.
cool.

It's actually 25 megawatts the zumwalt has turbines that produce 78 megawatts. This ship is completely electric currently they have a little over 50 megawatts to spare by the time you use propulsion and other weapons systems.

The current gun is is the Long Range Land Attack Projectile. It can fire 3 rounds a second has a 100 kilometer range and only uses 800 kw. It has GPS guidance and even at 100 km will hit with in 3 meters. It is,also capable of shooting incoming missiles. Something a rail gun has yet to do. Now the reason they have 3 generators was to keep one as backup. With a rail gun you can't do this as it's 27 megawatts would be used well most of it.

The advantage of the rail gun would be reduced cost but it will have reduced capabilities then the 155 mm cannons. But the biggest is simple 3 rounds a second 10 rounds a min sounds like a lot but keep on mind a canon could send 180 in the same time period. That's why the have the quick loading system and can even resupply from another ship.

Oops! Dahlgren, Virginia. Sorry. It is White Sands NM btw.

They are going up to 10 shots per minute this year. That was reported on the other railgun thread from earlier this year.

Seeing two in 12 seconds is pretty amazing!

Looks like the lag time is just the recharge time and the amount of energy you have available can make that a lot quicker. How fast it it going BTW?

I think they were referencing directed energy weapons, not the rail guns.

a reply to: humanoidlord

I stand corrected, there has been active research on magnetic rail guns since the 19th Century. However, I don't believe that any actual working models were ever made, not that I've found.

a reply to: dragonridr

the round cost is 800,000 to 1,000,000 compared to 30,000..

the range even at 27 times the cost is 60 km short of railgun range.

and it is supposed to be anti missile capable.. yet to see of course.

now thats going off your idea of what they are doing.. the new round for the 155mm is the excalibur round with a range of only 30 miles... 70 miles short of the railgun.. the 800,000 per round so 2.4 million$ per second... lol.. they wont do that.. excaliber is like 70,000$

how so??

the railgun shoots 100 miles.
yes it is a line of site weapon.

a reply to: Reverbs

A post before, the topic of directed energy weapons came up, and they were told that they were line of sight.

In one of my earlier posts I conjectured, correctly I might add--but won't--that that is why weapons of that sort will be used aboard aircraft, at altitude they'll be much more effective.

impressive. imagine one of those on each arm of a giant mech-suit. hours of fun!

I'm a little confused here. Check it out

"The 10 MJ railgun system has our third-generation railgun launcher, and includes our fifth generation pulsed power system and a new mounting system that allows the launcher to elevate and train for better targeting," Nick Bucci, vice president for Missile Defense and Space Systems at GA-EMS [General Atomics Electromagnetic Systems], said in a press release. "This represents a leap forward in advancing railgun technologies, offering reduced size and weight for the launcher, twice the energy density in a significantly reduced pulsed power footprint, and more capable hypersonic projectiles."

"We'll continue to develop and mature these technologies, perform risk reduction, and test under real-world conditions to ultimately deliver a more capable, effective, and cost-efficient solution to counter future threats."

GA-EMS conducted projectile component testing earlier this year. The testing also demonstrated a continuous two-way data link between the in-flight projectiles and the ground station.

UPI.com, Aug. 1, 2017 - New railgun ready for testing.

This is going to "Dugway Proving Ground in Utah" (same source).

Uh, the other one in NM is BAE, right? Does this mean there are two models?

10 MJ! Crazy!! Article says it can land, airs, or sea based.

The future is here! All they need now are graphene based supercapacitors.

a reply to: TEOTWAWKIAIFF

Not anymore. There were two, but BAE bought out the company working on the East Coast. So now they're both BAE.

Knew you would know the answer!

I SO need to get a life. Heh.

a reply to: penroc3

i smell a rat why would a rail gun sound like a regular cannon and making a muzzle flash like a cannon.

a reply to: proteus33

Because you're talking about temperatures of 1,000C when it's fired. The aluminum that gets flaked off ignites because of the temperatures at the time it's fired.

“A lot of people think a railgun is not going to make a lot of noise,” Garnett says. “It’s electrically fired, and they expect a whoosh and no sound.” In reality, when the bullet emerges, it lets out a crack as electricity arcs through the air like lightning.

The railgun gets its name from two highly conductive rails, which form a complete electric circuit once the metal projectile and a sliding armature are put in place. When current starts flowing through the device, it creates a powerful electromagnetic field that accelerates the projectile down the barrel at 40,000 gs, launching it in a matter of milliseconds. Aerodynamic drag along with a million amps of current heats the bullet to 1,000 °C, igniting aluminum particles and leaving a trail of flame in its wake. The researchers estimate the muzzle energy based on the mass and velocity of the bullet in the barrel and from precisely timed x-ray snapshots during flight.

Thank you for the update and information.

I have seen news reports on this system in the past, and it is fascinating technology.

I had read about the consideration given to building a space-based platform called "Hammer of Thor" (IIRC, and the proposal was decades ago), where the military would lift a couple dozen telephone pole sized projectiles that were truly nothing but dead weight, but that if dropped from space would come with such velocity that they negated the need for nukes, pure kinetic energy supplied all the power needed.

I don't think it was ever deployed bc of the cost of getting the platform up there to begin with, but I don't trust anything the government when it comes to either the military or space, so I really really don't trust what it might say about the military operating in space and so I wouldn't know if we had something like that or not.

My question, though, is this:

What is the huge benefit here over regular missiles/guns? Someone said this system is cheaper? Cheaper in comparrison to what?

I understand that the velocity of the projectile negates the need for some explosive charge on the receiving end, but that in and of itself doesn't necessarily mean it's an improvement, there must be something, so I am asking.

It is a triumph of technology, though, for sure. The only thing that I know that goes mach 7 are UFOs, which - ironically, also run on .... never mind.

What's the benefit over regular guns/missiles?

a reply to: Scrubdog

You can hit a target in minutes from ordering the launch, there's no launch signature to give away that you're under attack, and it tends to look just like something blew up, not an actual attack. Lots of drawbacks though.

Not secretly no, it's just nowhere near as well publicized.
