Forum:Ackbar's flagship

I need some info sourced. Here it is: "At some point Admiral Ackbar was apparently forced to transfer his flag from RAS Home One to RAS Independence, probably due to severe battle damage in combat with Executor." That is from the Battle of Endor article. Source? Also, what does RAS stand for? Rebel Alliance ships? Chack Jadson 14:13, 28 April 2007 (UTC)
