The leader of a faction in the Temporal Cold War who allies with Nazi Germany in an altered 1944.
Vosk leads the Na'kuhl, a faction in the Temporal Cold War that has escaped from Daniels using stealth time technology. In Storm Front, Enterprise finds itself in a 1944 where Vosk's aliens have sworn allegiance to Nazi Germany, giving the Nazis advanced weapons in return for the materials to build a temporal conduit back to their own era.
In Storm Front, Part II, Archer joins forces with Silik to stop him. The destruction of Vosk's plans restores the timeline and brings the Temporal Cold War to an end. Vosk was played by Jack Gwaltney.
