Calian Projector is a device that creates Hardlight Projections. the ships that carry this device are: X-33 judicator, Titan Battleship, Colossus Supercarrier, and the CC8 Archangel. these projections come in many shapes and colors, the shapes and colors are not for looks as they do different things. for example the hexagonal shape fires 6 projectiles that creates a reflective barrier, and while the Star shape spins at a insanely fast speed firing projectiles in all directions or tearing a ship's hull apart.
but the Calian Projector is also used in construction work for setting hardlight supports to hold up the structure to allow the worker drones to set up the remaining frames
