"The inconvenient truth is that our Navy has 12 carrier groups and all are now obsolete. The Chinese have developed an antiship ballistic missile (ASBM), the DF-21D, nicknamed the “carrier killer.” It has a range of 1,200 miles and can fly at speeds higher than Mach 5. During descent to the target, it can fly at Mach 10. That’s like launching one in Chicago and hitting the Statue of Liberty three minutes later.
We have no missile-defense systems that can counter the DF-21D. The Navy has a ballistic-missile-defense system, but the problem is it doesn’t work. Last year the Navy performed a test in which it tried to intercept two ASBMs. It couldn’t hit either one. This was a planned test—the Navy knew when the missiles were coming, from what direction and how many. Imagine a surprise attack on a carrier with 20 missiles incoming at the same time."
