Some though have called the carrier a 21st Century version of a battleship — high on looks and weapons but can be taken down by modern weapons. Critics note air-power killed the battleship, people now suggest super-sonic 'carrier-killer' missiles will make the carrier a relic of the past. With their cost in the billions of dollars, some point to killing off carriers as an obvious cost saving measure.
Carriers though still have a lot of uses. Many navies like India and China are adding them to their arsenal and they are still feared by many. While carriers might be old, they are a symbol of power that no missile or submarine below the surface can match yet.
