A little known huge advantage that the allies had during WWII is proximity fuses in shells- these are bullets fired from guns, not rockets! They experience both the tremendous linear acceleration from the explosive charge (>10,000gs) and high centrifugal force from the rifling (rotation). The fuse is a complicated radio electronic circuit of the 1940s, meaning it used vacuum tubes. It was powered from a lead acid battery. The firing would release the acid to start the battery.
Anyway, to get this delicate circuit to survive the firing, it was encased in a solid. So perhaps the tardigrades could survive the impact if they were frozen in ice instead of suspended in liquid? I read that they can survive ice...
