Watch Science Ninja Team Gatchaman online: Episode 52 The Secret of Red Impulse

To be able to see his father! Carrying this wish in his heart, Ken follows the whereabouts of the mecha. Before him somebody is shot and wounded. It's Sabu, a friend from Ken's childhood. When Sabu sais that he saw Ken's father in Huntwall, they both go there. In Nambu's office, Katse makes a bold appearance in disguise. He leaves saying that if the world does not surrender to Galactor in Huntwall, the V2 plan will be realized. The V2 plan is the terrible plot to make the Van Allen belt descend with a special rocket, thus extinguishing mankind with radioactive flames... Nambu orders the remaining four team members to stop the rocket without Ken. But the teamwork breaks apart and they can't use their missiles. The God Phoenix is surprised by the mecha and with skill they manage to defeat it, but they were definitely at a disadvantage. Meanwhile, Ken has met Sabu's treason and is held isolated by the defense minister in order to lure the spy Kentaro Washio into a trap. But coming to the rescue is Red Impulse. He scolds Ken that now is not the right time to ask such sweet things like how his father is. He then tells him the actual situation. Joe and the others have arrived in Hontwall, and before their eyes, the rocket takes off into the sky. Blaming the fact that Ken was not there, the Science Ninja Team is told by Nambu that Red Impulse himself is Ken's father.
