Sniper Turrets crush them very effectively. 24 Sniper/Spider turrets kill 1 Mark I Raid Starship every 6 seconds. It can stress your caps a little if you have to deal with a lot of Mark III Raid Starships, but it isn't unreasonable.
Also, I'd really prefer if AI Raid Starships had the same stats as human Raid Starships. I'd even say the human Raid SS could have its health come down.
