I know that Wildcats occasionally enaged and shot down Condor recon aircraft. They also performed missions in North Africa in support of Torch. I think the first A2A kill against Germany by an American pilot was by a Wildcat.
I expect the Hellcat to hold it's own, as it was a great fighter in it's own right. An I happen to be of the opinion that the F4U Corsair was the best American fighter of WW2.
