Yeah I'm not up on my supersonic aero anywhere near enough to work out max-Q for their very pointy projectile, but I'll point out that 'suddenly hitting MaxQ' is a jerk problem, not an acceleration one. MaxQ is MaxQ, whether you've been cruising at that speed and air density for hours or just hit it out of a near-vacuum.
I think centripetal / launch acceleration dramatically outweighs air drag though, by analogy to the SR-71. The max thrust divided by its dry mass gives a maximum thrust/weight of about 1g, and that thing could cruise at Mach 3+ which is about halfway to Spinlaunch's 5000 mph.
Their little teardrop projectiles have got to be way lower drag than anything with wings and intakes, and it's probably much heavier for its size than the SR-71 as well, so I can't imagine MaxQ on these things gets past 10-15g.
