Liaoning is no match for a USN strike group. But if J31 deployed onboard. If Liaoning carries 12 J31 then it becomes a credible threat to USN carrier strike group immediately. Just the fact Liaoning carries J31 will be big big unknown factor to the USN, it will acts cautiously. J15 USN fear none. J31 with WS19 will be ready in 2019.
