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"

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!

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

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