Planetary Assault: What gets damaged first?

[ajohn505]

Hi all. Long time reader, first post in awhile.

I just picked up SE4 again after a long hiatus.

Here's the scenario: Lets say I have a planet with 10 Large Weapons Platforms. No fighters or satelites, just the platforms.

If Enemy ships attack this planet, will the Weapons Platforms take damage before the other facilities on the planet? Also: on the SphereWorld thread there was mention of planetary shielding. I know that there's gravitational shielding, but can you also build something to protect your planets from conventional damage?
