Communist Party in China funded a new super missile that can sink a Nimitz aircraft carrier within 900 miles of the coast. The new missile is called the Dong Feng (or East Wind) 21D. They attack our government computers all the time. It's a cyber cold war.
DF-21 is a two-stage, solid-fuel, medium-range ballistic missile (MRBM) developed by the 2nd Aerospace Academy (now China Changfeng Mechanics and Electronics Technology Academy) in late 1970s. It was the first solid-fueled ballistic missile deployed by the Second Artillery Corp. The missile carries a single 500 kt nuclear warhead, up to 2,500 km range. The DF-21 also served as the basis for the submarine-launched ballistic missile (SLBM) JL-1 (CSS-N-3), used on the XIA-Class SSBN. In 1996, an improved variant, the DF-21A, was introduced. Currently, an estimated 60-80 DF-21/DF-21A are in service.
The only thing that can protect a carrier is a HELLADS (High Energy Liquid Laser Defense System) pod on the flight deck. Maybe have some HELLADS on the West Coast. Maybe have a LGM-118 Peacekeeper re-commissioned, because it is 15 years newer than the LGM-30 Minuteman III in service until there is plenty of HELLADS manufactured.
