Re: Well, its good to see the QE going out to sea.
It would be even better if there was any realistic chance of having a sufficient, dedicated RN escort group for her,
Why? In hobby wars against tribals and insurgents there's no need for a battlegroup, as the carrier is simply a mobile airfield beyond their reach. Against any sovereign nation with even the most modest military pretensions, a battlegroup is simple a larger floating collection of targets.
In the age of high speed anti-ship missiles and supercavitating torpedoes, you simply cannot afford to put a battlegroup within operating range of an attacker who can launch missiles from subs, fast patrol boats, ships, aircraft or land sites. The high speed torpedoes (200+ knots) may be as much of a hazard as the more obvious missiles, and as soon as you start losing capital ships the whole battlegroup concept is looking difficult, as basic escort group is only three to five destroyers and frigates, split between air defence and anti-sub. If the attackers get lucky and disable the carrier, then the whole mission is lost, if they disable the one or two air defence escorts then the remaining group is vulnerable.
The Iranians have been experimenting with swam attacks, with reverse engineering a British designed high speed boat to take their fast attack craft speeds up to 70+ knot speeds, and are also attributed with an unmanned surface vessel "kamikaze" attack on a Saudi frigate at sea a few months back. That last one is all on Youtube if you care to watch. That's the sort of "drive up" attack a battlegroup really should protect against, but the torpedoes, mines and missiles remain a very high risk threat. You'd really need to have 100% confidence in all of your technical systems to cope with the various and possibly simultaneous hazards, and be absolutely sure that your limited number of big ticket assets won't be outflanked by the far faster, less conventional approaches of asymmetric warfare.
In this day and age, a big carrier is simply a codpiece for the admirals.
