Completing the current add-ons to the Tier 2 starships available in Star Trek Online is the new Exeter Class. A variant on the famed Constitution Class, the Exeter honors the 400 crew members of the U.S.S. Exeter who were killed by a biological agent in 2268. The Exeter Class comes equipped with an Ionized Gas Sensor that provides a bonus to Starship Sensors and can modify a torpedo to track down and target a cloaked ship. The Ionized Gas Sensor can be equipped in any console slot of any Cruiser.
