MNS Virtue was a destroyer of the Navy of Masada. In 1903 PD, the ship was assigned to the base on Blackbird. Prior to the Battle of Blackbird, it was the only other vessel besides MNS Principality that could give any type of resistance against an invading Grayson-Manticoran fleet. Virtue was sent to warn the MNS Thunder of God about the attacking fleet, and was later destroyed in the Battle of Blackbird. The destruction of the ship was unknown to Captain Honor Harrington. (HH2)
