The aircraft carrier gained ascendancy over the battleship in WWII, as signalized by the attack on Pearl Harbor, now almost 70 years ago. Although it maintains an impressive aspect, just as the battleship did at that time, its vulnerability to new weapons and capabilities is obvious. One can only hope that the proof of this will not be given in some vain display of imagined invulnerability.
I think that AEGIS can off set this threat a little.
We lost six carriers to enemy action {sank} in WW2. The Langley, Lexington, Yorktown, Wasp, Hornet, and Princeton. The threat was always there and always will be. The more modern systems built by enemies to sink one the more modern system we should build to detect and counter. The Pentagon needs to get on the ball about defense programs. We played cat and mouse with Russia for years with carriers and subs. Of course we had helos and S-3 Vikings devoted as carrier based anti-submarine {detection} aircraft.
A carrier is still the fastest way to get a fully equipped/operational and supported multitask air response from one part of the word to another in the shortest time frame. When a carrier arrives the airbase is there and ready to go as is about 70 aircraft. The Air Force is great at getting long range bombers from here say to the Middle East in short order. We've made some huge strategic blunders Navy wise including fleet reductions. We are well below 300 ships the lowest since before WW2
. One mistake was ending the two carrier 24/7/365 presence in the MED SEA. Another is the decrease in available west coast carriers in the event Suez is blocked. Yet another was downgrading the Navy Fighter program by ending F-14 production. We had the perfect mouse trap. Now we have a compromise. BTW we went from 1967 to 1981 without a carrier transiting the Suez canal.
There is no such ship as an unsinkable ship or an undetectable one either for that matter. It is a matter of lack of national will to rebuild our defense forces. Try to design a new aircraft and 50 idiots in congress will hold it up a decade deciding who's state gets the contract.
