The Manta-Sub is first seen prior to the hijacking of a Russian nuclear submarine. As it docks on top, the crew board and attack the sub's crew. Following Aquaman's intervention, it would seem that David Kane is the only user of the sub now.
Meeting with Orm
Sometime later, in the North Sea, David Kane sits atop the sub whilst waiting for Orm to show up. When his subordinates arrive, they attempt to give Kane his payment for accomplishing his task; but he refuses, demanding that Aquaman be brought to him (as punishment for killing Kane's father).
