On the Invincible-class starships, shouldn't the XO hold the rank of Fleet Captain? It should be taken into consideration since you could have up to, say, 4 other officers onboard the flagship who also hold the rank of captain and the 69 other ships in the task force would be commanded by Captains (or in lieu of full Commanders). It would make some sense for the number officer to hold the rank of Fleet Captain, in recoginiton to their status as the executive officer of the flagship and the deputy commander of the task force. 71.185.238.205 23:56, December 1, 2012 (UTC)
