RE: Harriers on the deck: The record was set on HMS Invincible in 2004 with a mixed package of FA2s and GR7s, 18 jets in all, op launched off the deck in under 5 minutes.
HMS Ark Royal in 2010 on the Auriga deployment before decommissioning had 12 AV8Bs working the deck.
Back to the subject:
Just because it's being looked at again does not mean the decison will change, however it's all driven by the Treasury, not MOD, so the decision will not be capability or strategy based
