no they dont intend on using them as point defence wepaons, that task will fall to metal storm, million rounds a minute, and a new generation of
energy weapons. One of which the department of defense obtained a patent for last year, some sort of proton beam weapon.
The rail gun will be for very long range engagment of surface targets, a much cheaper alternative to guided missles, and much longer ranges than with
conventional naval artillery.
But I agree they are a long way off, still. I have been folowing the development of railguns since the early eighties, when I was told fantastical
tales of a magnetic launcher that could hurl things great distances and at high velocities, by my roommates electrical physics proffesor , that had
been built in the nevada deserts.Then again when one of my college proffesors worked on the first one at Larwence/Livermoore National Lab.
Its taken almost 30 years of contiuous work to get them to this level, and they are still a long way away.
At first the the rails would destroy themselves with every shot, just from the enormous magnetic forces oppossing each other.
There have been some material breakthroughs in the last few years that have helped move it along but 10 shots to a rail is not any where near where a
combat weapon needs to be.
Its a very daunting task to get one of those things stuffed into a the hull of a ship, provide it with adequate power, carry all that current to the
weapon, sheild all of the other stuff on the ship from the intense localized EMP.
One very interesting concept i read about was an adaptation of supercavitation to an underwater ballistic weapon.
Basically an auto cannon fitted in an underwater turret that fires a super cavitating projectile.
The projectile will be almost like an under water rocke fired from a gun and will contain a small amout a propellant that will burn and the gasses
will escape through small holes in the tip of the round.
This gas will form an envelope around the bullet, isolating from the friction of the water. I think they used a 25mm round and achieved a muzzle
velocity of around 2500-3000 feet/sec.
The gun will be be guided by sonar and blue-green lasers, to which sea water is transparent.
There is also work being done on an brilliant underwater powersource.One originally designed for a torpedo motor.
Seawater is injected a super high pressure into a reaction vessel, and it swilrs around, much like water down the drain, at the same time, finely
powdered aluminum is injected in the chamber, and the engery of the flowing around the chamber is enough to start an exothermic reaction with the
water and the aluminum. The oxygen from the water binds with the aluminum, making aluminum oxide, and heat(steam).
The steam drives a turbine and is exhausted like a jet engine.
It is an under water solid state jet engine.
