The RVA-818 is an experimental starfighter equipped with Cybernetics Link System and Lock-on Laser system. It proven itself to be an exceptional machine during its testing phase, having completed its flight tests flawlessly. However due to unstable nature of Cybernetics Link System, during a test flight the spacecraft along its test pilot went out of control before it was eventually self destructed.
Development had been indefinitely halted in the aftermath of the accident, with two surviving prototypes were sealed. However, following the failure of Operation Meteor, the two crafts has been brought back to operational status and are being deployed as the main force in Operation Rayforce.
