The main weapon is very long range nuclear missiles that home in on enemies. (surplus MX missiles) It's special weapon fires point defense lasers at nearby objects. (surplus SDI systems) In Star Control 2, most earthlings were imprisoned on Earth, but you, the player, were a rogue Earthling in a spaceship that was an ancient alien artifact 100,000 years old.
