CMA Vostok

The UNSC Vostok was a Colonial Military Administration Frigate.

The Vostok was part of Battlegroup 4 led by Captain Veredi of the UNSC Heracles that was sent to Harvest to find out what happened to the scout ship Argo and Harvest. The battle group consisted of his own ship, the Destroyer UNSC Heracles, and two Frigates, the UNSC Arabia and UNSC Vostok. They were sent to discover the fate of the colony on the planet Harvest, where contact had recently been lost with the local populace. The Battle Group encountered a Covenant vessel holding station in Harvest orbit and the Vostok was destroyed almost instantly by the Covenant's superior firepower. All hands were lost aboard the vessel.

Its partner ship, the Arabia, was destroyed at the same time, and the badly-damaged Heracles was forced to retreat.
