Well in star wars there are Particle shields and ray shields. Apparently capital class particle shields are meant to stop micro meteors, asteroids, and other low-energy kinetic objects from harming the ship but do JA against really high energy kinetic projectiles such as proton torpedoes and fighters. 

So yes, a 600 ton projectile moving at 30,000 meters per second would...do some damage. lol.

Back reading to where I left off right now.
