The T-Sub is a custom-designed submersible craft owned and operated by the Teen Titans.
The T-Sub only requires one pilot to operate the helm, but a support team is required for the comm and navigation systems. Typically, Cyborg pilots the T-Sub, but Nightwing has been known to pilot it upon occasion as well. When not in use, the T-Sub was usually moored at an underwater hangar bay beneath Titans Island. The Titans once used the T-Sub to stage an assault against the terrorist organization known as the H.I.V.E..
It is equipped with a scanner sonar array, counter-communications jamming systems, force field technology and is armed with concussive torpedoes.
