I don't know if this has been done already, but here's a factory which you can blow up! I've included a single mission, and tested on stock 1.4
The drawback is you have to place it on low ground, because it sits on sea level. It probably has other bugs that i didn't discover yet.

Here's how i did it:
1. Cloned a ship
2. In the zon file removed collision from all spheres
3. In CollisionableObject set rebound=0
4. In the sim file, found correct values so that the object doesn't bounce.
You get a kill report in your logbook, but if you don't want the report, use the CoastalDefense Controller & cmdr instead of AIShip controller & cmdr.
Feel free to use, mod and improve it!
