66 sorties, maybe, but they got kills. There are a couple of tales of 152s fighting tempests late in the war. One account was told by one of the pilots.. A flight of 3 152s were heading low to engage some tempests that were attacking something (trains? Front lines? I can't remember what). They saw the tempests and promptly one of the 152s plowed into the ground (pilot error? Malfunction, the pilot telling the tale didn't know). They got into a fight and the pilot that was telling the tale explained that he got into a turn fight with one of them and was out turning it. He was firing his guns then they all stopped (out fo ammo? Probably a G-related jam IMO). He kept turning waiting for something to happen, and it did. The Tempest couldn't turn with the 152.. It's wing dipped and the pilot couldn't recover because they were already barely above trees as it was. The tempest pilot died.
April 24 1945, Walter Loos ran into a group of VVS fighters over Berlin -- my guess is that at this time of the war they were late Yak9s or LA7s -- and shot down 2 of them.
It was rare, sure, but they were in full production and if the war had ended 6 months later they'd have replaced most of the doras, I bet.
I know this is a fun "what if" plane for AH. But it still falls within the guidelines that HTC set up for "allowed planes"

(*whisper* I just wish it performed like the monster it was supposed to be! */whisper*)
