"—the only device on Earth capable of sinking an aircraft carrier—....a two stage, land-launched missile with a maximum estimated range of 2,700 to 3,000 km. Its single fuel-air explosive warhead packs 200 to 500 kilotons."

Since a kiloton is 2 million pounds, this missile carries a half a billion pound warhead. It simply must land on the carrier, and sink it with its own weight.

500 kilotons is a larger yield than the W-88, our second largest thermonuclear warhead in the active US arsenal.
