'''Orbital Defense Platforms''' are orbiting [[Space Stations ]] used by the [[Imperial Navy]] personnel and [[Planetary Defense Force]]s for defense of a world against enemy spacecraft. They are deployed within a planets planet or moon's gravity well and are armed with a variety of weapons. The most sophisticated Orbital Defense Platforms, those used to defense defend [[Adeptus Mechanicus]] worlds and key planets, have no crew at all and use complex logic engines to detect and fire at enemy vessels which do not broadcast the correct identification codes.^{{Fn|1}}

*'''Orbital Weapons PlatformPlatforms''': An Orbital Weapons Platform usually mounts mount several [[laser ]] batteries capable of striking at the enemy before they get too close to the planet.^{{Fn|1}}*'''Orbital Defense Laser PlatformPlatforms''': Are are armed with massive [[Defense Laser]]s, large [[laser ]] cannons capable of penetrating a capital ship's armour. Built around a powerful [[plasma reactor]], a defense laser platform is armed with several of these large cannons, giving it the ability to fire them in every direction. Defense laser platforms are particularly effective at destroying fast-moving [[escort ]] craft sent ahead of a main enemy fleet to conduct reconnaissance and raiding.^{{Fn|1}}*'''Orbital Torpedo Launcher''': Orbital [[Torpedo]] Launchers''' and missile batteries are one of the greatest deterrents to an enemy intent on attacking an [[Imperial ]] world. They can attack from a distance to disrupt an enemy fleets fleet's advance and deliver a lethal blow against vessels which approach too closely to a planet. They have proved effective against attacks by [[Ork]] and [[Chaos]] forces.^{{Fn|1}}
