The Starfleet Constitution class Cruiser is an extensive upgrade and refit of the original Constitution cruiser from the mid-23rd century, but incorporates the latest technological innovations seen in the newer Excalibur and Vesper classes.
The Constitution (and her sister ships, the Excalibur and Vesper) are the Cruiser class ships of the second tier of starships for available for command in Star Trek Online.
The Constitution and her sister ships become available once the player attains the rank of Lieutenant Commander. Like most Cruiser class ships, the Excalibur, Constitution and Vesper rely upon their high hull ratings and prefer wide weapons arcs due to their sluggish manoeuvrability compared to the Science Vessels, Light Cruisers and Escorts. However, with their large warp cores, they can provide far more power to their systems than any of these other ships, meaning their shields will recharge more quickly and their weapons will have a shorter cooldown period. Additionally, Cruisers have Device slots than any other class in its tier.
