Notes: Based on the Earth Force Omega Heavy Cruiser from Babylon 5 RPG Ships of the Galaxy book page 16. The ships size came from the Starship Size comparison chart compiled by Dan Carlson, July 13, 2003. One of Earth Forces largest and most powerful ships fielded. Constructed the vessel to the Star Trek Spacedock version with the weapons lowered to a sensible level to prolong a gunfight.

MKII interceptors do variable damage. As an offensive weapon it does 3 damage to a ship or as an interceptor to an incoming weapon 15 as B5 RPG rules. I carried it over from the B5 game as the same. I usually generate up the shielding but not with this version of the ship.

Any suggestions
