Royal Navy Hellcat I's (F6F-3) from 800 squadron were involved in escorting Barracuda attacks on the german battleship Tirpitz from April to August 1944 in Alta Fjord, Norway. One of these operations, on 8 May 1944, the Luftwaffe fighters flew up to protect the battleship. Some of the 800 squadron Hellcats from HMS Emperor went to attack the German aircraft and shot down 1 Fw-190 and two Bf-109G fighters. The Hellcats suffered one loss to the Luftwaffe and another to anti-aircraft fire. Sub Lt. B. Richie claimed the Focke-Wulf and went on to claim a total of 6 kills, becoming one of only a few Royal Navy Hellcat aces.
I have some list of engagements between the F6F and 109's. I'll try to dig it up for you
