The SDPS is a propultion system developed by Stevonia. The SDPS makes a ship go very fast and produces little to no heat. The SDPS runs on two blue energy crystals, and these can last up to five marins, making this much more efficiant than a normal Fire-Producing Propultion System (FPPS). The SDPS comes in light blue and pinkish-purple (dubstep pink). The SDPS was first built for the Inknava, and later the "Phaze" Class Energy Fighter.
