    If you attack it head on you have a very short window of opportunity before it’s past you

    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.
