Defenses

There is no (known) limits on number of Defenses, and no impact on the fields places available on the planet.

Open to discuss, see: Strategies

You can't build following defenses without the required level of Researches or Buildings


 * Robot and Nanite are not mandatory, but this is a must have!
 * Notice: Defenses can be installed on Planets but also Moons (except Interceptor and Interplanetary missiles, as can't build silos, but Interceptors of the planet also be used for Moon, Should be...)
