>>102871915eh, depends which godzilla
AT fields can easily block futuristic nuclear weaponry far superior to our strongest modern warheads point-blank, so early/weaker godzillas wouldn't be able to land a scratch
most versions of the big G should be in for a decent fight overall, might have a hard time keeping up speedwise or getting through AT fields initially but his regen/durability should allow him to survive nearly anything an EVA can dish out
