UNSC Thermopylae

The UNSC Thermopylae was a destroyer in the UNSC Navy during the Human-Covenant War. The ship was part of Battle Group-3 at the Battle of 18 Scorpii in 2543. During the battle, the Thermopylae took moderate damage and would likely have been destroyed, but she and the rest of Battle Group-3 was saved by insurrectionist forces.

The ship is obviously named for the famous Battle of Thermopylae, where the 300 Spartans made a last staand against the Persian Empire.
