woohoo just beat it on easy with the kestrel and was able to unlock the red-tail in the process. Them shields get harder and harder to pierce in late game. Ended up swapping out my hull beam for a heavy ion so I ended up with 2 lasers II's a heavy ion and an artemis. Not sure if I want to try normal now or I will probably just try and beat the game a few more times with some other ships/layouts on easy.
