UPDATE:Looks like the Point Defense Turret *does* shoot. But it does it silently. And it fires 1 salvo approx every 1 second. And the aim isn't all that good. Totally not what you expect after reading the Encyclopedia description.
This needs a mod to rectify the thing. A PD system has precise characteristics.
This one is a joke, and isn't of help in the Macross Missile Massacres the game is so fond of.

Changing subject...
I just did that bad mission in Act II, the one that has you go from Mwari to Dagda system using an uncharted L-Point or something.
I read on the internet that many Win7 users have a problem with that mission. I had problems too.
The mission itself is easy. The problems start when you want to get back to base: the game will hang or crash! I don't know if it's the GOG version or Win7.
But I know how to avoid the hanging and crashing
Play the mission, follow the events, kill the bad guys, do what you're supposed to do.
Basically in this mission you have to protect 4 transports. Assuming they survive, eventually they'll leave the system, and *then* you will be told to do the same (look at your mission objectives).
This is what you must change:
leave the system before the transports do. Simple as that. The mission won't fail. All goals will be fullfilled. With the difference that your game won't hang or crash.
But it will lag
Don't know why. The lag cyclically gets bad, then better, then disappears, then starts again.
Endure it. Set a course for Lucrecia's Base, go save, then quit. When next you launch I-War2 there won't be lag.
