Re: Carriers??
Also just a comment on availabilities - "Peace Time availability" and "War Time availability" are two very different things. Also dont confuse "War Time availability" with "Dropping bombs on a far off country in support of (not your country's) ground troops availability".
In a proper war where your forces are defending your own land or its ground troops, the aircraft will fly with any number of things that would prevent it flying in peace time. In peace time, the loss of an aircraft for any reason will see generals brought before government inquiries, hard questions, cuts in funding, etc, etc. The loss of an aircraft whilst dropping bombs on a far away land to anything except enemy SAM fire would also be unacceptable in the main.
But in an actual war, those aircraft go up. It doesnt matter if its due mainetance on some bit of equipment, that maintenance will be deferred until after the next attack. No questions asked.
