A shield that protects the planet from reconnaissance, attacks or capture can be installed on your Orbital Station in the tabs «Shield» or «Planets», its cost is 1 Solarium or X Energy (depending on the type of planet), and the duration is from 6 to 21 hours of protection (depending on the level of the "Shield" skill in the Skills tab at the Orbital Station, which increases the duration of the Shield by 9 minutes for each out of 100 levels learned).
The Shield does not protect the planet from Blockades, however, it makes it impossible to rob Energy and Solarium from the planet when using the appropriate modules for Blockades.
Do not confuse Shields with structures on the planet called «Shield Generator»!
Players can build the Shield Generator building on their planet, which gains more powerful protection for all buildings on the planet with each new level. With the Shield Generator, it will be harder for the enemy fleet to break through the defenses of your planet, and it will become impossible for occupying ships like Titan to land and conquer your planet.
However, it should be understood that the only Shield Generator will not give tangible protection of the planet! It is necessary not only to upgrade it to the maximum level but also have 3-5 Missile towers of the maximum level in order to turn your planet into a real fortress!
ATTENTION! The upgrade levels of the rest of the buildings on the planet also affect the power of the general defense of the planet under the Shield Generator.
