UNSC Spirit of Fire

The UNSC Spirit of Fire (CFV-88) is a modified UNSC built around 2418. Its Ship Emblem reads "Exitus Acta Probat," Latin for "The result justifies the deed." Over one hundred years after being built, it was refitted for military service during the period of the Human-Covenant War. The AI on board the Spirit of Fire is known as Serina.

In Halo Wars, players will be able to command the troops of the Spirit of Fire including Warthogs, Scorpion Tanks, Marines, and at least five Spartans from SPARTAN Group Omega. It has been speculated that the Spirit of Fire was engaged in the Battle of Harvest, or a nearby moon of Harvest.
