SES Nightbringer

The Nightbringer is a unique special combat vessel used by the Silent Watch, much of it's true capabilities are unknown and/or classified, but it generally specializes in ECM and long range detection/jamming, outfitted with bleeding edge technology, it's been active since the start of the second Galactic war.

It often emerges unseen and undetected seemingly at random, it's jamming abilities ensuring no transmission or signal escapes its web, and it's sensors ensure none escape it's gaze, after activation, it hunts it's targets with it's vast array of weaponry

Despite being twice the size of a Super Destroyer, it's disturbingly fast and agile, chasing down targets until destruction, it then vanishes back into the void without so much as a Whisper, leaving only voiceless ruins in it's wake.

It was last seen on the road to cyberstan, clearing paths for allied destroyers, though they never, if only rarely, caught a glimpse of the Nightbringer.

It's true launch date is unknown.
