DF-21

'East Wind') is a two-stage, solid-fuel, single-warhead medium-range ballistic missile (MRBM) developed by China's Changfeng Mechanics and Electronics Technology Academy.

[9] The basic variant DF-21 had a range of 1,770+ km,[3] and a payload of 600 kg (1,300 lb) consisting of a single 500 kt nuclear warhead, with an estimated circular error probable (CEP) of 300~400 m; this version did not enter operational service.

[9] This is an anti-ship ballistic missile that has a maximum range exceeding 1,450 kilometres (900 mi; 780 nmi), according to the U.S. National Air and Space Intelligence Center.

[14] The US Department of Defense stated in 2010 that China has developed and reached initial operating capability (IOC)[15] of a conventionally armed[16] high hypersonic[17] land-based anti-ship ballistic missile based on the DF-21.

This is the first ASBM and weapon system capable of targeting a moving aircraft carrier strike group from long-range, land-based mobile launchers.

Such a missile may have been tested in 2005-6, and the launch of the Jianbing/Yaogan satellites would give the Chinese targeting information from SAR (synthetic-aperture radar) and visual imaging respectively.

[25] In 2014, the U.S. Navy reported that images that have appeared on the internet showed similarities of a DF-21D re-entry vehicle to the American Pershing II missile's RV, which was withdrawn from service in 1988.

The Pershing II's RV weighed 1,400 lb (640 kg) and was fitted with four control fins to perform a 25-G pull-up after reentering the atmosphere, traveling at Mach 8 and then gliding 30 nmi (35 mi; 56 km) to the target to pitch into a terminal dive.

[35] Use of such a missile has been said by some experts to potentially lead to nuclear exchange, regional arms races with India and Japan, and the end of the INF Treaty between the United States and the Soviet Union, to which the People's Republic of China is not a party.

[citation needed] First, the missile may not be able to single-handedly destroy its target, as the warhead is believed to only be enough to inflict a "mission kill" that makes a carrier unable to conduct flight operations.

[38] Finally, although the DF-21D has radar and optical sensors for tracking, it has not yet been tested against a ship target moving at-sea at up to 55 km/h (30 kn; 34 mph), let alone ones using clutter and countermeasures.

The missile's "kill chain" requires processing and constantly updating a carrier's location details, preparing the launch, programming information and firing.

[45][46][47] US officials subsequently assessed that the People's Liberation Army Rocket Force (PLARF) had fired four medium-range ballistic missiles in total.

[11][49] On 26 August 2020, a DF-26B was fired from Qinghai province into an area between Hainan and the Paracel Islands as a response to a U.S. U-2 spy plane entering into a no-fly zone during a Chinese live-fire naval drill the day earlier.

[54] The War Zone reported two possible warhead configurations; a DF-21D-style "double-cone" tip, and a hypersonic glide vehicle (HGV) similar to the DF-ZF on the DF-17 missile.

Conventionally-armed DF-3 missiles were bought by Saudi Arabia in 1988, but were not used during the 1990-1991 Gulf War due to their poor accuracy and the potential for collateral damage.

[56] The Central Intelligence Agency (CIA) examined the modified nosecones and concluded that nuclear warheads that might be purchased from China or Pakistan could not be fitted.
