Well ( as I'm sure everyone will agree ) I'm no strategic expert, but it strikes me that;
If we stick to asymetric warfare, carriers are very useful
( would the 'Black Hawk Down' incident have happened if there was a US or USMC carrier handy ? )
If we end up in a real, full-on war, carriers will be very useful.
On another tack, going back to the beginning of this thread, I remember seeing high photo-quality images of an American port supposedly taken by a Russian RORSAT quite a few years ago - the point is this thing could map out the UNDERWATER details to quite a depth...
Was that just B.S, or what with that & ever quieter attack subs ( air independent SSK's in particular ) are SSBN's more likely to 'go the way of the battleship ' ?
Hey presto ! Trident replacement budget problem solved...Treasury please PM me for where to send your large cheque in gratitude.
More likely, whether that RORSAT capability exists or not, it doesn't take a genius to see anti-satellite warfare becoming trendy, now other people are joining in and treaties seem redundant.
