S3E9 · Battle at Barnard's Star

As Dagon continues his attack on the Argo, Derek Wildstar tries to locate the Galman base. He discovers that Galman ships, not satellites, are reflecting the lasers toward the Argo, and launches an attack on them. The Cosmo Tigers provide additional support, destroying the ships. Derek locates the relay stations and orders a surprise attack. Dagon launches a proton missile at the Argo, but the Star Force fires the Wave Motion Gun, destroying both the missile and the base. Dr. Sane tries his best to save the old man rescued from the planet, but is unsuccessful. Derek then learns that the woman he rescued from the planet is four months pregnant and decides to send all the women on the ship, except for Nova, back to Earth. 306 days remain before the sun destroys Earth.
