U.S. Navy to Deploy Rail Guns by 2011

Walter Francis writes "The U.S. Navy has apparently been busy. They have been focusing heavily on the next generation of weapons and propulsion systems, including Microwave, Laser, and Electromagnetic-Kinetic weapons, more commonly known as railguns. What specifically surprised me was the fact that the Navy plans to deploy these systems as early as 2011, on their DD(X) frigates. The range of these rail guns is estimated to be over 250 miles."

    If you'd read the article, you'd know that the railgun is better because:

    • Its cheaper than missles, at least 3 times
    • It delivers more energy to the target, and penetrates deeper into hardened targets
    • The ammunition takes less room to store, and doesn't pose a risk of explosion like missles or artillery shells
    • The shells have guidence, and are just as accurate as missles, but travel much much faster

    In other words, it brings a lot to a Real World(TM) battle.

  7. Range to horizon? Really? by Theaetetus · · Score: 4, Informative
    So theoretically, you can shoot these things farther than you can see on the horizon, if the velocity's high enough. Does this mean air support would be crucial in relaying information about targets below the horizon and that the naval ships can technically hit ships that have no way of retaliating.

    Hmm... Well, let's ask Mr. Google. Hey, Google, how far is it to the horizon at sea level? In fact, say you're actually 100' up on the bridge of a cruiser. Google says: "11 miles".

    So, yes, 250 miles is farther than the horizon. Theoretically.

    And is this a new thing? Well, let's let Google tell us again...

    So, in other words, nothing new here in terms of "targets that have no way of retaliating". That's been the case since WWII, when in nearly all of the carrier battles, the opposing forces would be over the horizon and everything was either via plane or via large guns with planes as spotters.

    It has a few obvious benefits, especially as compared to rockets/missiles:

    1: It cannot be tracked in a meaningful amount of time. In other words, because of the comparatively high speed (6 minutes in the air, as compared to 60 minutes or 10 minutes for the ERGM and LRLAP), and significally smaller size (30 inches as compared to 60 inches for an ERGM or 88 inches for an LRLAP) and higher impact force (16.9 MJ as compared to 2.2MJ and 7.8 MJ for the ERGM and LRLAP respectively) the rail cannot be anticipated anywhere nearly as easily.
    2: Because of this, it is almost impossible to deflect it/move out of the way.
    3: Also, the cost of individual rails will be significantly less than the cost of an individual missile.

    Well, Abraham Lincoln wouldn't be a name for a destroyer. President names are used for Nimitz-class super carriers. In fact, Lincoln is already taken by the CVN-72. I think destroyers take their names from famous Navy personnel.

    The article mentions all this. Traditional gas powered navy ships have two sets of turbines, one for propulsion the other for electric. The ships that will be carrying the rails guns will have turbines that power electric motors, the guns, and the rest of the ship. Sounds like it couldn't fire while moving but I doubt they'd really need to.

    Additionally, it's a lot cheaper and safer to drop shells on an enemy from 250 miles away than it is to send an aircraft. Even though these shells are ballistic the do have guidance systems that let them control their 'fall'. They should be just as accurate as a cruise missle.

    The rate of fire is slower than with traditional artillery(6 per minute), but their time to target is faster. So they can drop the same amount of rounds in a 15 minute engagement.

    They won't replace carriers, but may lighten the load for the pilots. If we can take out the radar sites with these before sending in the planes it will save some lives.

    Well I know the story is already two hours old (gasp), but it appears to be ill-supported. The linked article plainly states ...

    1. That this warship class will enter service in 2011:
    "When the U.S. Navy's first integrated power system (IPS)/electric drive warship arrives in 2011 as the DD(X), the service will mark a technological breakthrough ..."

    2. That this warship class will debut without a rail gun or any other advanced weapon system:
    " When the new ship arrives in service it will be armed with very advanced, but conventional weaponry, including two United Defense 155mm Advanced Gun System cannons and an 80-cell vertical launch system for various guided missiles. But these systems are stepping stones to greater capabilities ..."

    3. The Navy won't even decide whether to fund a rail gun for years:
    "Whatever investment decisions are made for weapons the next several years, the Navy already is engineering the potential these technologies require, according to Collins and his IPS/electric drive team for DD(X)."

    The speculative linked white paper goes no further, advocating that a rail gun *proof of concept test* *could* happen by 2008:

    "A focused technology development program that leads to a series of experiments that culminate in a full-scale extended-range naval rail gun proof-of-concept demonstration in fiscal year 2008
    is a sensible approach."

    For a sense of how little this means, consider there was a successful "proof of concept" demonstartion for airborne anti-laser systems -- "Star Wars" SDI technology -- in 1984.
