    Why is the Navy leaving proven technology and to put the rail gun on DD251 would endanger ship. These rail guns use tremendous amounts of power, so what happens if you lose two generators? Captain has to make a real quick decision and no decision would be good for the ship. The same applies to the new carrier catapult which are powered by steam as its free and available. This is becoming scary as Navy brass with Roughead at helm cannot see that these catapults will require bigger demands of power which means you have something that can fail. Catapults are proven technology, and their failure rate is near 2%. To have weapon systems and catapults be dependent on generators is absurd and believe your just doing it to spend the money.The CIC probably does not know a thing about this, but a defenseless ship because generators fail is just down right scary.

    Where do you think that steam comes from? It's piped from the steam generators in the engineering plant. Still takes power to make, but with an electric catapault (which, considering it's the tech on most new "fast-launch" roller coasters, means it probably has a similar low failure rate) you don't have hundreds of pounds of steam released, actually saving wear and tear on the engineering plant. In the cat space, you now have banks of electromagnets that don't corrode, don't catastrophically fail. Remember, a straight deck carrier is proven technology, and how many of them do you see about now? As for the weapons, same point. Yes, you're dependant on power generation, but you no longer need as much magazine space, and your projectiles are inert, or at least much less explosive and ready for a fire to blow the ship in half. I'm sure there will be problems at first, but that's why it's new technology. Before it gets fielded, the kinks should be worked out, and procedures for casualty recovery in place.

    Seven years to get into production? This has taken too long already. This should be fast tracted. The ships (DD-51) they want to put them on are almost out of date now.

    Cool, now we just need to scale this down to where we can put this on an Abrams!

    My god! The 9MJ EMgun finally after what 25Years or so since the RFP !! It sure looks like the one we submitted from GD Pomona.

    @24414563 Swords were proven technology too, why did we move onto a mechanism that had moving parts, chemicals, cloth, and could only be used to kill someone once every few minutes? Oh yeah . . .

    I can see adding this to the Abrahms tank

    Another waste of taxpayer money on a toy project that goes nowhere.

    the concerns re: generators failing could be prevented by a nuke powered boat?? yes? no?

    As retired Navy, I think this is great as long as the system is robust, and can take allot of contamination without causing misfires. I would rather have a few less machs and allot more reliability, if that is an option.
