Unidentified starship 21211
Unidentified starship 21211 was an unresponsive Federation starship picked up on Sahil's relay station's sensors in 3188.
While searching for the USS Discovery for Commander Michael Burnham, Aditya Sahil was able to pick up two Federation starships within six hundred light years – this one and unidentified starship 21210. A holographic display indicated intermittent long range sensor contact, that there was no response to hails due to possible transmission error, and that it had an indeterminate (possibly non-Federation) warp signature. Its last recorded speed was warp 5 on heading 350 mark 1. (DIS: "That Hope Is You, Part 1")
