Orbital Defence System is a critical defensive Technology, and players should aim to unlock it as soon as they reasonably can. Researching it unlocks Tier 1 Orbit Defense System structures - guns capable of attacking enemy ships and fleets in their planet's orbit.

These have two general functions; direct fire against enemy fleets in the orbit of the planet they are constructed on (100 damage per shot every three minutes), and destroying 25% of all troops that land as part of a raiding or invasion attempt, regardless of cool-down.

Multiple guns do not stack for anti-invasion purposes (only the effect of the best one is used), but they do stack for direct fire damage. However, a skilled opponent will bait their fire with a cheap Scout before any major attack, then move in while the weapon(s) are on cool-down. This can allow invasion fleets to get in undamaged, but any raiding or orbital bombardment attempts will still have to face surface-to-orbit fire. With all this in mind, players should definitely build at least one of these structures on each planet they control.
