The Klingon Bird-of-Prey is especially Designed with combat in mind. This ship was in service with the Klingon Defense Force in the mid-24th century.
Even though the ship was very maneuverable and had strong attacking disruptor weapons – the ship couldn’t fire with its back turned on the enemy, therefore it only had weapons to the front of the ship.
The one thing crews would look out for would be that the Bird-of-prey as it was installed with a cloaking device, making it invisible to sensors and visuals. This made any klingon Bird-of-prey to feared among federation and freighter crews.
Klingon tactics employs having three to five birds of pray in a war zone that are cloaked and one to two other birds of pray that are not. When an enemy comes in for the kill to attack the one klingon ship, it is then set upon by an additional five. these tactics have been use by klingon force since the 22nd century.
