There are a number of small scale combats involving the hellcat and ace/well trained Japanese pilots. They are the exception rather than the rule, but thy do provide a clue that the Hellcat was not so overwhelmingly superior to the Japanese counterparts as one might assume. The best "lage scale" example I can think of is the Allied counterattack at Phil Sea (6/44). With no mor than 35 fighters remaining, but apparently these being 1942 veterans, the loss rates in the American strikes whilst over the japanese carriers were certainly higher than that. Trouble is, i dont have figures on the numbers of Hellcats shot down in that part of the battle. Total US losses, including those ditched near the US Fleet,amounted to 135 aircraft
