    Sure, in a dead heat and as long as there aren’t any big waves. Also, you do realize that it’s possible to attack this thing from other directions than directly behind it while it’s at full speed, right?

      If you attack it head on you have a very short window of opportunity before it’s past you and if you try from the side you’ll have to be really really good at geometry. And that thing won’t go in a straight line while it’s in enemy range.

        So, you have to be accurate. Like we’ve been doing for hundreds of years with projectiles, even non-guided ones. Check.

        if you try from the side you’ll have to be really really good at geometry

        So… good like as in a computer doing the math? Check.

        And that thing won’t go in a straight line while it’s in enemy range.

        Bad news friend, they can’t turn for shit due to ground effect, and they can’t ascend or descend either. There’s a reason these things were immediately abandoned as a viable concept after only 3 years in operation and without seeing any combat.
