Same to how normal MVP is determined; Damage dealt. Except you wouldn't be able to attribute which damage was dealt by which carrier except by extrapolation

Unless it's a combined fleet. The flagship of the main fleet of the combined fleet always  gets MVP if you go into yasen. Possibly because of a bug.
