The Dongfeng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng ({{zh|t=東風|s=东风|l=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. A part of the Dongfeng missile family, the DF-21's development started in the late 1960s, and it was completed around 1985–86, but not deployed until 1991. It was developed from the JL-1 submarine-launched missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers;{{Cite web | title= Military Power of the People's Republic of China 2008 |url=http://www.defenselink.mil/pubs/pdfs/China_Military_Report_08.pdf | publisher=Office of the Secretary of Defense |page=56 (p66 of PDF) }} approximately 10-11 missiles can be built annually.{{Cite web|url=https://www.usnwc.edu/getattachment/23a01071-5dac-433a-8452-09c542163ae8/From-Bottle-Rockets-to-Lightning-Bolts--China-s-Mi|archive-url=https://web.archive.org/web/20160304204038/https://www.usnwc.edu/getattachment/23a01071-5dac-433a-8452-09c542163ae8/From-Bottle-Rockets-to-Lightning-Bolts--China-s-Mi|url-status=dead|title=Pradun: From Bottle Rockets to Lightning Bolts, p.12|archive-date=March 4, 2016}}

Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. It is thought to be able to carry a high explosive, submunition for tactical/theater-level missions, or a 300 kt nuclear warhead for strategic strikes. The latest variant, the DF-21D, was said to be the world's first anti-ship ballistic missile (ASBM). The DF-21 has also been developed into a space warfare-capable anti-satellite weapon/anti-missile weapon carrier.

Though the launcher vehicle itself is mobile to reduce vulnerability, an actual launch unit requires support vehicles that can cover a 300×300-meter area, making it hard to move quickly and easier to detect. Also, the wheeled launcher is not made to travel off-road and requires firm ground when firing to prevent backblast and debris damage due to the hard launch, restricting its firing locations to roads and pre-made launch pads.{{cite web |url=http://fas.org/blogs/security/2010/09/df21c/ |title=DF-21C Missile Deploys to Central China |last1=Kristensen |first1=Hans M. |date=September 28, 2010 |website=fas.org |publisher=Federation of American Scientists |access-date=27 November 2013}}

==Guidance and navigation==

Between 2009 and 2012, China launched a series of satellites to support its ASBM efforts:

China was reported to be working on an over-the-horizon radar in 2013 to locate the targets for the ASBM.{{cite web|url=http://www.fas.org/sgp/crs/row/RL33153.pdf|title=CRS RL33153 China Naval Modernization: Implications for U.S. Navy Capabilities--Background and Issues for Congress}} An apparent test of the missile was made against [https://fas.org/man/eprint/gobi.pdf a target] in the Gobi Desert in January 2013.{{cite web|url=http://www.globalpost.com/dispatch/news/regions/asia-pacific/130130/chinas-test-df-21d-missile-mock-us-aircraft-carrier-gobi-d|title=China tests DF-21D missile on mock US aircraft carrier in Gobi desert|author=Daniel DeFraia|work=GlobalPost}}

==Re-entry vehicle==

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 {{convert|1,400|lb|kg|abbr=on}} 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 {{convert|30|nmi|mi km|abbr=on}} to the target to pitch into a terminal dive. Army training manuals about the missile are available on the internet and public open-source literature extensively describes it; the DF-21 has a comparable range and payload. Though much is made of the DF-21D's damage infliction ability based solely on velocity and kinetic energy, the Australian Strategic Policy Institute has calculated that the energy of an inert {{convert|500|kg|lb|abbr=on}} RV impacting at Mach 6 had similar energy to the combined kinetic and explosive power of the American subsonic Harpoon anti-ship missile, which is one-quarter the energy of the Russian supersonic {{convert|12,800|lb|kg|abbr=on}} Kh-22 missile traveling at Mach 4 with a {{convert|2,200|lb|kg|abbr=on}} warhead.{{cite web|url=http://www.aviationweek.com/Article.aspx?id=/article-xml/AW_01_27_2014_p18-657278.xml&p=1|archiveurl=https://web.archive.org/web/20141006085611/http://aviationweek.com/awin/us-navy-sees-chinese-hgv-part-wider-threat|archivedate=October 6, 2014|title=U.S. Navy Sees Chinese HGV As Part Of Wider Threat|website=Aviationweek.com|date= 27 January 2014}}

=Impact on naval warfare=

In 2009, the United States Naval Institute stated that there was "currently ... no defense against [a warhead able to destroy an aircraft carrier in one hit]" if it worked as theorized. It was reported in 2010 that China was finalizing development of a MaRV warhead for the DF-21.{{cite magazine|url=https://www.wired.com/2010/03/china-testing-ballistic-missile-carrier-killer/|title=China Testing Ballistic Missile 'Carrier-Killer'|date=March 29, 2010|magazine=Wired}}{{cite news|url=http://www.asahi.com/english/TKY201008250379.html|title=China's anti-ship missile is nearly operational|archive-url=https://web.archive.org/web/20100827131804/http://www.asahi.com/english/TKY201008250379.html|archivedate=August 27, 2010|newspaper=Asahi Shimbin|date=August 26, 2020}}{{cite web|url=https://www.andrewerickson.com/2010/12/china-testing-anti-ship-ballistic-missile-asbm/|title=China Testing Anti-Ship Ballistic Missile (ASBM); U.S. Preparing Accordingly–Updated With Latest Analysis & Sources|date=December 25, 2010|website=andrewerickson.com}} The United States Navy has responded by switching its focus from a close blockade force of shallow water vessels to return to building deep water ballistic missile defense (BMD) destroyers. The United States has also assigned most of its ballistic missile defense capable ships to the Pacific, extended the BMD program to all Aegis destroyers and increased procurement of SM-3 BMD missiles.{{cite web|url=http://www.fas.org/sgp/crs/row/RL33153.pdf|title=China Naval Modernization: Implications for U.S. Navy Capabilities—Background and Issues for Congress.}} The United States also has a large network optimized for tracking ballistic missile launches which may give carrier groups sufficient warning in order to move away from the target area while the missile is in flight.Pomfret, John. [https://www.washingtonpost.com/wp-dyn/content/article/2010/12/24/AR2010122403009.html "Military strength is eluding China."] The Washington Post, 25 December 2010. Kinetic defenses against the DF-21D would be difficult. The Navy's primary ballistic missile interceptor, the SM-3, would not be effective since it is designed to intercept missiles in the mid-course phase in space, so it would have to be launched almost immediately to hit before reentry or from an Aegis ship positioned under its flight path. The SM-2 Block 4 can intercept missiles reentering the atmosphere, but the warhead will be performing high-G maneuvers that may complicate interception.[http://nationalinterest.org/blog/the-buzz/chinas-carrier-killer-really-threat-the-us-navy-13765 Is China's "Carrier-Killer" Really a Threat to the U.S. Navy?] - Nationalinterest.org, 2 September 2015 By 2016, the US Navy was testing the vastly more capable SM-6, which is designed to intercept ballistic missiles in the terminal phase.{{Cite web|url=https://nationalinterest.org/blog/the-buzz/how-the-us-navy-trying-make-chinas-carrier-killer-missiles-18766|title=How the U.S. Navy is Trying to Make China's 'Carrier-Killer' Missiles Obsolete|first=Dave|last=Majumdar|date=December 16, 2016|website=The National Interest}} The SM-6 began deployment in 2013.{{cite web|url=https://www.naval-technology.com/projects/standard-missile-6/|title=Projects: Standard Missile-6|publisher=Naval Technology|accessdate=August 4, 2021}}

In late 2013, a Russian Military Analysis report of the DF-21D concluded that the only way to successfully counter it would be through electronic countermeasures. Conventional interceptions of high-speed objectives have worked in the past, with the Russian report citing the 2008 interception of a malfunctioning satellite by a U.S. cruiser, but in that situation the warship had extensive knowledge of its location and trajectory. Against an attack from the Mach 10 DF-21D without knowing the missile's launch point, the U.S. Navy's only way to evade it would be through electronic countermeasures.[http://www.navyrecognition.com/index.php/news/defence-news/year-2013-news/december-2013-navy-naval-forces-maritime-industry-technology-security-global-news/1423-electronic-countermeasures-maybe-only-way-to-counter-chinese-df-21d-ballistic-missile-.html Electronic Countermeasures maybe only way to counter Chinese DF-21D Ballistic Missile] - Navyrecognition.com, 14 December 2013

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.{{cite journal |last1=Erikson |first1=Andrew S. |last2=Yang |first2=David D. |year=2009 |title=On the Verge of a Game-Changer |journal=Proceedings Magazine |volume=135 |issue=5 |publisher=United States Naval Institute |url=http://www.usni.org/magazines/proceedings/2009-05/verge-game-changer |access-date=3 February 2011 }}{{cite news |title=Can a treaty contain China's missiles? |author=Mark Stokes |author2=Dan Blumenthal |url=https://www.washingtonpost.com/wp-dyn/content/article/2010/12/31/AR2010123104108.html |newspaper=The Washington Post |date=2 January 2011 |access-date=3 February 2011}}

=Skepticism=

The emergence of the DF-21D has some analysts claiming that the "carrier killer" missiles have rendered the American use of aircraft carriers obsolete, as they are too vulnerable in the face of the new weapon and not worth the expense. Military leaders in the U.S. Navy and Air Force, however, do not see it as a "game changer" to completely count carriers out.{{Cn|date=January 2021}}

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.[http://www.airforcemag.com/MagazineArchive/Pages/2013/December%202013/1213china.aspx China's Carrier Killer: Threat and Theatrics] - AirForcemag.com, December 2013

Secondly, there is the problem of finding its target. The DF-21D has a range estimated between {{convert|1,035|to|1,726|mi|nmi km|abbr=on}}, so a carrier battle group would need to be located through other means before launching. Over-the-horizon radars cannot pinpoint a carrier's exact location, and would have to be used in conjunction with Chinese recon satellites. Though recon aircraft and submarines could also be used to look for the carrier, they are vulnerable to the carrier battle group's defenses.

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 {{convert|55|km/h|kn mph|abbr=on}}, 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. The U.S. military's AirSea Battle concept involves disrupting such kill chains. Some U.S. analysts believe that the DF-21D does not fly any faster than Mach 5.[http://breakingdefense.com/2014/01/house-gop-defense-heavies-slam-china-after-hypersonic-missile-test/ House GOP Defense Heavies Slam China After Hypersonic Missile Test] - Breakingdefense.com, 14 January 2014

The DF-21D may also not be as fast as theorized. While ballistic missiles reenter the atmosphere at speeds between Mach 8-15 at an altitude of {{cvt|50|km|ft|abbr=on}}, increasing air resistance in the denser low-atmosphere region reduces terminal speed to around Mach 2 at {{cvt|3-5|km|ft|abbr=on}}. It cannot acquire its target until this point due to ionization blockage, leaving a relatively short time to actually search for a ship. This could enable the target to leave the area if the missile is detected soon enough before it engages its terminal sensors, and the slower speed upon reentry leaves it vulnerable to missile interceptors.[https://www.taiwannews.com.tw/en/news/3996716 Can China's DF-21D missile destroy US aircraft carriers as advertised?].

It is a two-stage missile with a range of 3000 km. Weight may have been reduced by using composite materials.{{cite web|url= https://thediplomat.com/2018/04/revealed-chinas-nuclear-capable-air-launched-ballistic-missile/ |title= Revealed: China's Nuclear-Capable Air-Launched Ballistic Missile |website=The Diplomat |date=10 April 2018 |first= Ankit |last=Panda }} 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.

It was in development by 2018. In 2018, the United States projected it would be ready for deployment by 2025.

The missile is carried by the Xian H-6N bomber; the aircraft has a recessed underside to carry the missile externally.

Saudi Arabian purchase

The DF-21 may have been exported to Saudi Arabia.{{Cite book |author=The International Institute for Strategic Studies |title=The Military Balance 2024 |date=13 February 2024 |publisher=Routledge |location=London |isbn=978-1-032-78004-7 |page=384 }} In January 2014, Newsweek reported that the missiles were purchased in 2007. 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. Saudi Arabia wanted the shorter-ranged but much more accurate DF-21 as an upgrade. The United States approved of the purchase on the condition that the missiles were conventionally-armed.{{cite web |last1= |first1= |title=Exclusive: CIA Helped Saudis in Secret Chinese Missile Deal |url=https://www.newsweek.com/exclusive-cia-helped-saudis-chinese-missile-deal-227283 |website=Newsweek |date=22 April 2014 |access-date=2 June 2024}} 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.{{cite web |last1=Fitzpatrick |first1=Mark |title=Saudi Arabia's ballistic-missile programme: an overview |url=https://www.iiss.org/en/online-analysis/online-analysis/2021/08/saudi-arabia-ballistic-missile-programme/ |website=International Institute for Strategic Studies |date=27 August 2021 |access-date=2 June 2024}}
