If I remember correctly, you can only use two of those runways.
Also check the polycount every now and then, make sure you don't go over 2400(?) or somethin.
The doors can be done:
Having them in a separate model. But placed in relative position to where the hangars are in the main model.
And having them animate to open for built planes.
If you're lazy you can ignore doors just right out though, still works.
For the defensive turrets:
A) You can have the player manually upgrade them-- via Overlord-Firebase Style.
Basically you can upgrade it to have MGs or Missile Turrets.
This means, that the W3D Module you're going to be using is W3DTankDraw.
Also, you'll have to provide spawnbones for the turrets.
Since you're using Firebase logic, you should make the turrets as "INFANTRY" and have a weapon to kill them on destruction of the airfield.
B) Or ya' know, you can have one MG and Missile Turret on different sides.
