Core Mechanics
All POSes are initally erected with a control tower which provides a protective forcefield, CPU and powergrid space for adding modules, a strontium calathrate (stront) bay for reinforcement and a UI to configure related roles and access to the forcefield.
Once the tower is fueled and a password entered for the first time it will generate the forcefield bubble, granting protection from enemies. Ships and structures inside the forcefield cannot be locked or lock anybody outside. Smartbombs and bombs don't work either. While the forcefield protects everything inside it, the tower itself is exempt from this feature.
If the stront bay is fueled and an unfriendly entity starts shooting the tower, at 25% 
shield;
- The tower will resist all locking attempts,
- Any modules requiring CPU will be turned off,
- Shield hitpoints will no longer regenerate over time,
- The fuel and stront bays will be locked,
- Parts of the configuration UI will reject input.
- The tower shields cannot be repaired.
At this point the structure is in what is called reinforced mode or RF for short. A timer visible to anybody on grid begins depending on how much stront is in the bay, for a maximum of 41.7 hours. Once the timer reaches zero it is possible to start shooting or repairing the tower again. If the shields are repaired up to 50% any attempts to destroy it can be impeded by another reinforcement cycle at 25% shields, provided the stront bay has been refilled.
Modules
Control towers only provide the protective forcefield without modules. To receive the benefits of various modules, they must be purchased and anchored after the control tower has been onlined.
