The USS Yelchin was a Federation starship operated by Starfleet in the 32nd century.
When Earth was threatened by the Dark Matter Anomaly in 3190, the Yelchin participated in the evacuation effort. It reported that it had completed its evacuation orders, shortly before Fleet Admiral Charles Vance called for all remaining ships to depart. (DIS: "Coming Home")
This ship appears to have been named after Anton Yelchin, who played Pavel Chekov in Star Trek, Star Trek Into Darkness, and Star Trek Beyond.
