The weapons factory is necessary to produce spaceships of all kinds. At the same time all defensive arrangements are built in the weapon factory. Every step raises the productiveness and thus shortens the construction times.

^* higher levels of the weapons factory produce faster, than lower ones. Example: A weapon factory level 10 needs only one tenth of the time for the production of a unit compared to level 1. Micro-system accelerator allow an further acceleration.
