DF-41

The Dongfeng-41 or DF-41 (NATO reporting name: CH-SS-20 ) is a fourth-generation Chinese solid-fuelled road-mobile intercontinental ballistic missile operated by the People's Liberation Army Rocket Force (formerly the Second Artillery Corps). DF-41 is the fourth and the latest generation of the Dongfeng series strategic missiles developed by China. The missile was officially unveiled at the China National Day military parade on 1 October 2019.

Design
The missile reportedly has an operational range between 12000 to 15000 km. It is believed to have a top speed of Mach 25, and to be capable of MIRV delivery (up to 10). The development of the MIRV technology is reported to be in response to the deployment of the United States national missile defense system which degrades China's nuclear deterrence capability. The project started in 1986, and may now be coupled with the JL-3 program.

Though there have been reports that the DF-41 can carry 3 to 8 warheads, analysts think it most likely carries only three warheads, with the additional payload used for many penetration aids.

Development
In April 2013, Taiwan's National Security Bureau head reported to the Legislative Yuan that the DF-41 was still in development, and not yet deployed.

The U.S. Department of Defense in its 2013 report to Congress on China's military developments made no explicit mention of the DF-41, but did state that "China may also be developing a new road-mobile ICBM, possibly capable of carrying a multiple independently targetable re-entry vehicle (MIRV)", which may refer to the DF-41.

In August 2014, China's Shaanxi Provincial Environmental Monitoring Center website accidentally published a news report about an environmental monitoring site for a DF-41 ICBM; the news report (and entire website) was taken down shortly after getting public attention.

In August 2015, the missile was flight-tested for the fourth time. In December 2015, the missile was flight-tested for the fifth time. In April 2016, China successfully conducted the 7th test of DF-41.

On January 23, 2017, China was reported to have deployed a strategic ballistic missile brigade to Heilongjiang province, bordering Russia, along with another strategic ballistic missile brigade deploying to Xinjiang.

In November 2017, just two days before U.S. President Trump's visit to China, the DF-41 was tested in the Gobi desert.

On October 1, 2019, China publicly displayed the missiles for the first time on its 70th Anniversary National Day military parade.

Rail-mobile versions
On 5 December 2015, China conducted a launcher test of a new rail-mobile version of the DF-41, similar to the Russian RT-23 Molodets.

Silo-based versions
In 2021, the Federation of American Scientists (FAS) said China was building 120 missile silos for DF-41 near Yumen in Gansu and another 110 missile silos near Hami in Xinjiang.

A third site was discovered to be under construction near Ordos in Inner Mongolia in August, 2021. The new site will hold more than 100 ICBM.

Together, the three new missile bases will house 350 to 400 new long-range nuclear missiles, U.S. officials said.
