Currently, four models are planned.
The "Blackfish" class rapid patrol vessel is equipped with shield generators, S-grade laser cannons and kinetic cannons. Compared to standard patrol vessels, it uses a Spirit Infusion Engine Module, which typical patrol vessels are reluctant to install, enhancing agility and speed.
This is to facilitate the use of wolf pack tactics by the patrol vessels.
Although small, its defensive capability is limited by the patrol vessel's grade and isn't very substantial; it will explode if hit by cannons. However, the "Blackfish" class can rely on its speed and agility, making it easier to dodge locks, reduce the likelihood of being hit, and more easily disperse formation to surround and attack ships much larger than itself.
In short, its design philosophy is for the small to overcome the large through agility.
