Notes: Although the propusion system is much slower than the warp engines of the Federations Heavy Cruiser Class, the Cloaking device and plasma energy weapon make this a formidable starship. When the Romulan Empire obtained Klingon warships and equipped them with cloaking devices, the Federation mounted a covert operation into the Romulan Nuetral Zone. On stardate 5031.3, the Enterprise was able to obtain a device, thus nuetralizing the Romulans advantage and maintained the balance of power.
