Star Fleet Academy Class of Y143
Colony planets can’t always count on a Star Fleet or local National Guard ship to protect the planet. Sometimes the planet may be too remote or there just aren’t enough ships to adequately patrol the area. Colonies that have the means can purchase orbital defense satellites which provide some means of self-defense against attacking ships. Defense satellites can disrupt an attacking ship(s) just long enough for reinforcements to arrive. In some cases, the defense satellites can repulse the attacking force.
Typical Federation defense satellites are equipped with all types of phaser cannons (except for the large type-IV phasers), laser cannons, photon torpedoes, or guided drones. They are typically deployed in groups of five.
