That is a wonderful animation turret and also fitting factorio theme.
I have an idea suggestion: This laser turret will have x2 range of rocket turret, very slow attack time (charging up etc...) and the laser shot should be bigger and deal area damage (something like this https://mods.factorio.com/mod/kj_laser) This could be big gun for defense aim for heavy targets (or asteroids if it hit those like rail gun). Better and more beautiful replacement for rail gun(?).
Cheers!
