Some unbalances with Astro trains?
I did not catch quite what was killing my Turret Astro Train MK II, but something made it go pop very very quick. Granted, I had a ~600 unit fleet, but mostly Mk I and II units. It went down realtivly slow to start with, then some unit suddenly got in range and boom, 70% to 0% in a few seconds. I do not have the save here now, but the units I used was Fighter MK I and II, Bomber Mk I and II, Armor booster MK I, cruiser MK I, Leech starship (and a select few captured units like 2 or 3 sentinel frigs MK I and IV, and a couple of laser gatlings and some other small stuff like eye bots and space planes.)
