Yes, but it also requires a crew of 300,000 and the likelihood of having a fleet beyond it is slim to none considering the state the galaxy is in. If that's the only ship with maybe like, a few escort Nebulon-B's that's one thing...
but if they've got that ship and a sizable fleet... I'm gonna say 'no', unless that SSD is running with a tiny crew and is nowhere near peak capacity. Even then, maintaining one costs vasts amounts of funds. It's why the Empire didn't have fleets of them.
