The Eastern Alliance destroyer is a spacecraft used by the Eastern Alliance of Terra. An Eastern Alliance destroyer tracks the Lunar Avion from Lunar Seven to Paradeen where it eventurally encounters the Galactica. Commandant Leiter commands the destroyer that is captured by the Colonials (Greetings from Earth). The destroyer manages to escape from Galactica, and returns to Terra with the Colonials on its trail (Baltar's Escape).
