The G forces are another thing. I wonder why they aren't stsrting wth missle platforms instead.
Sure, winged flight has uses, but taking a missle platform, adding small munitions instead of a big bang?
Regarding your missile platform question, there are several companies that already manufacturing loitering munitions, and long-range loitering cruise missiles are on the roadmap, so to speak.
Of course any planned action would likely try to strike first, by some means.
Price and ease of manufacture. Missiles are expensive and hard to build.
