This is
USS America. It is a Kitty Hawk class vessel. Last of its kind conventionally powered 84000 ton super carrier. Launched in 1964 and decommissioned in 1996. Sunk in 2005.
It took US airforce over 25 days of heavy bombing to sink her. How it was sunk and what took it to be sunk is classified. Even then the superstructure was still afloat albeit mostly submerged.
That is the quality of engineering that goes in to building these super carriers. They are built in such modular formation that flooding a chamber is not enough to cause cascade flooding to get the ship to sink. The newer ships are built with experience gained in the sinking of USS America.
As well as carrying numerous defensive weapons on board like ASW helicopters, Sonars, CWIS and ESSM air defence missiles, a super carrier is accompanied by around 10 ships that form the strike group which are responsible for protecting the carrier. These include destroyers frigates and nuclear submarines, with SAMs of the most modern types that are effective for any threat the strike group may encounter.
Anything less than a nuclear strike, is not going to have much effect to make a dent in this armour.
There are 11 strike groups like this in the US Navy. With a further 5 shown as retired. But most probably, to be ready in the event of an emergency, for active duty. (USS JF Kennedy being readied for joining the naval forces in 2025. )
Anyone thinking that they can take on such a fighting power head on and win, with current technology is having a pipe dream. There will be chinks in its armour that could be exploited. But it is not an easy task to accomplish by any account.
