Silent Destructors are in incredibly powerful long-range weapon, containd only in UNO Warships.
The design is unknown; it isn't even a cannon and is contained inside the ship.
Since all of Time contains Dark Chronoscopic and Chronoscopic due to the Time Matrix, from a fairly long distance away, the Silent Destructor can manipulate this without needing to fire a beam. Used in stalemate situations or as alast resort, as they require a lot of charging up.
Not even firing a beam, the Silent-Destructor manipulates the Time-Space Continuum with Dark Chronoscopic to contact the Dark Chronoscopic at the other end of the weapon, the other end being the target. The weapon will then cause natural diststers or twist time. In this way, it can cause comets to destroy the planet etc by speeding up time or by finding a possible traumatic effect on the planet.
They can do a similar effect on stars; by rewinding/slowing time on the star to stop it from working properly, killing the star system. Once this is done they can revert these effects after the enemies' colonies are defeated and claim the planet for themselves. With its large range, UNO often use it to destroy a planet far from their fleet's reach, such as the enemies' greatest manufacturing/economic planet, or what is most strategic to them/strategic to destroy.
There needs to be an incredibly strong defensive device to prevent the weapon from causing catastrophic effects.
The weapon can be used to destroy strategic locations, weakening the enemy when needs be. It's also a good demonstration of their power, as it's UNO's greatest weapon. The Silent-Destructor is also good for pre-emptive attacks as it can't be detected. This makes it good for simply causing fear and panic, useful in stalemate situations or war-enders.
