World defence

World defence means the defencive structure which you have emplaced upon your planet. World defences can assault any enemy ships but can also be used for refuelling, as airports for some craft, or as shielding for the world.

Outright defences
Outright defences include defences which are weapondary designed from ground up to inflict damage upon orbiting (enemy) vessels.

Shielding Towers
Shielding towers protect defences, buildings, machinery, any landed ships (which are vulenerable with no shields), and any people on the colony. These constitute to a giant planetary-spanning shield which can have immense values requiring bombardment from a massive fleet to be penetrated when used optiumly. Shields also prevent beaming of resources from the colony - stopping stealing and/or raids

Landing platforms
Certain types of vessels cannot land on planets; such as capital ships.

Certain types of vessels require a airport to land their space fairing vessels upon. On landing, crew & peoples join the planets and the vessels consume no energy. This comes at the cost of taking time to start up each craft; its slots in seconds.

Landing platforms range from handling 6000(basic) to as much as 36,000 slots.
