Secretly, you know exactly what this is.

The Aqua-Class Squid

DGA is a branch of Quincy Station, which creates underwater craft. DGA is the newest branch and is getting of to a good start. It has made only 120 models and only 37 are available to the public. The first model was the Aqua-Class Squid as seen in this photo. The craft is lightweight, lightly armored, fast, and can only carry three passengers. It uses a "tentacle" engine which is located behind it which is spun by a hydraulic system.
