The Dong Feng-26 or DF-26 (simplified Chinese: 东风-26; traditional Chinese: 東風-26; lit. 'East Wind-26'; NATO reporting name: CH-SS-18^[4]) is an intermediate-range ballistic missile deployed by the People's Liberation Army Rocket Force and produced by the China Aerospace Science and Technology Corporation (CASC).^[5]

Chinese sources claim the DF-26 has a range of over 5,000 km (3,100 mi) and may conduct precision nuclear or conventional strikes against ground and naval targets.^{[1][citation needed]} It is China's first conventionally-armed ballistic missile claimed to be capable of reaching Guam and the American military installations located there;^[3] this has led to the missile being referred to as the "Guam Express" or "Guam Killer".^[6]

The possibility that a DF-26 unit could have nuclear warheads makes it likely an adversary would target these missiles in a first strike.^[7]

The missile was officially revealed at the Chinese 2015 parade commemorating the end of the Second World War.^[3] In April 2018, it was officially confirmed that the DF-26 was in service with the People's Liberation Army Rocket Force (PLARF).^[8] The United States believes the missile was first fielded in 2016,^{[1][citation needed]} with 16 operational launchers in 2017.^{[9][needs update]}

On 26 August 2020, along with a DF-21D, a DF-26B was launched into an area of the South China Sea between Hainan and the Paracel Islands, one day after China said that an American U-2 spy plane entered a no-fly zone without its permission during a Chinese live-fire naval drill in the Bohai Sea off its north coast^[10] (the US confirmed a U-2 sortie but denied it was improper.^[11][12][13]) and came as Washington blacklisted 24 Chinese companies and targeted individuals it said were part of construction and military activities in the South China Sea.^[14][15][16] US officials subsequently claimed that the People's Liberation Army Rocket Force (PLARF) had fired four medium-range ballistic missiles in total.^[15][14] The missile tests drew criticism from Japan, the Pentagon and Taiwan and led to volatility in Asian markets.^{[17][15][14][18]} As of 2019, the DF-26 has not been tested against targets at sea.^[19]
