There is a combat flight sim called DCS where individuals repeatedly attempt different methods of killing carrier groups.<p>The general take away is that anti-aircraft/missile systems are good enough that the only solution is to saturate the air defense and exhaust the 500-1500 million dollar missiles the carrier group has on hand to deploy (assuming you got past the air wing).<p>A swarm of ultra-cheap drones each with 50-100kg of explosive changes the cost dynamics of defending a ship/carrier group.
