    Plane and simple distance + elevation. It sounds like it can shoot in a straight line over the horizen on open water. Eventulay with out uplifit it would just hit water with out loosing speed or drop.

    I could be wrong as im a computer scienets not a rocket one. Computers are harder.

    Also im a former cannoneer from the army.
    So i understand a littel bit about direct/ indierct fire from a cannon.

    I was in when the computers took over the calculations.

    We went from stop and fire for effect bieng 3 hours to 30 seconds. And started hiting a soada can every time. With a howetzer.

    It's still experimental, so much like the CV-22, it's definitely going through teething pains in terms of mean time between failures, but in time it will absolutely prove superior. The level of control and precision is just something you can't get out of steam for launching things like UAVs.
    I actually worked on that system. Provided mechanical support during testing on EMALS (ElectroMagnetic Aircraft Launch System) at NAS Lakehurst along with it's compliment AAG (Advanced Arresting Gear). Certainly troublesome but when the kinks are worked out it really will work. My understanding is there are two ships outfitted with it at this point, sea trials incomplete.
    Steam is still the dominant system but EMALS and AAG offer a broader weight/speed capability.

    Warning: I know Judo. If you force me to prove it I'll shoot you.

    Both are based on moving electromagnetic field. Like the old SEATAC levitating train. There was a plan at one time to make a hiway with that principle. IIRC Musk is using it.
    Whatever!
