The DF-15 (M-9; Dong Feng-15; NATO: CSS-6) is a short-range, road-mobile, solid-fueled ballistic missile developed by the People’s Republic of China. It has a maximum range of 600 – 900 km and can deliver a 500 – 750 kg payload, with conventional warheads optimized for precision strike, bunker-busting, and anti-runway operations. It is capable of striking Taiwan, the Korean Peninsula, and northern India from mainland China.

DF-15 Development

China’s Academy of Launch Technology (CALT) began developing the DF-15 on April 28, 1984. Designed primarily for export, the system was designated M-9 for foreign sale and DF-15 for domestic production.1 CALT began design work for the M-9 in October 1985 and first displayed the missile at the Asian Defense Exhibition in Beijing on November 4 – 11, 1986. China’s defense ministry approved the M-9 for production on March 2, 1987. On June 17, 1988, conducted its first flight test of the missile.2

China’s first DF-15 brigade entered service in August 1991.3 Following the DF-15, the PRC developed at least three variants of the missile: the DF-15A, DF-15B, and the DF-15C. 4

DF-15 Specifications

The DF-15 (CSS-6) is a single-stage, solid-propellant ballistic missile. It is 9.1 m long, 1 m in diameter, and weighs roughly 6,200 kg.5 The DF-15 can deliver a 500 kg to 750 kg payload up to a range of 600 km. For guidance, the system employs a strapdown inertial navigation system and its warhead features a “miniature propulsion system” for minor trajectory corrections.6 It can be armed with a variety of conventional payloads, including maneuvering, cluster and “bunker-busting” munitions.7 The DF-15 has an estimated accuracy of 200 – 300 m circular error probable (CEP).8

The DF-15 is a tactical missile designed to strike adversary weapons, grounded aircraft, command and control facilities, and other critical infrastructure. The missiles are launched from a Wanshan-produced transporter-erector-launcher (TEL), allowing the system to rapidly relocate after firing. The system’s estimated launch preparation time is 30 minutes.9

DF-15A (CSS-6 Mod 1)

The DF-15A is an improved DF-15 variant with a range of approximately 600 km.10 It is equipped with a high-explosive warhead and uses an inertial guidance system. The missile is reportedly nuclear-capable.11

DF-15B (CSS-6 Mod 3)

Beijing first revealed this missile publicly during an October 2009 military parade in Beijing. Unlike the DF-15A, the DF-15B possesses a biconic, finned warhead capable of terminal maneuvers. Several analysts suggest this warhead incorporates a radar-correlation terminal guidance system, with a potential accuracy of up to 30m CEP. Its reported range is greater than 725 km.12

DF-15C (CSS-6 Mod 2)

China first unveiled the DF-15C variant in 2013. This variant carries an earth-penetrating warhead.13 Distinguished by its rounded nose and extended length, Chinese media has cited DF-15C’s range as over 850 kilometers.14 Media reports additionally suggest that the warhead can penetrate 25 meters of reinforced concrete.15

Service History

While the DF-15 is believed to have entered service in 1990-1991, the DF-15A became operational in 1996, and the DF-15B in 2006. 16 In 1995, China test-launched six DF-15 missiles into the sea near Taiwan, with one missile experiencing mid-flight failure. China launched four more missiles in the direction of Taiwan in 1996.17 Additional flight tests took place in 2003 and 2004. 18

It is believed that between 350-400 DF-15 missiles and 90-110 TEL launchers were operational in 2009 and that at least 30 missiles have been produced annually since.19
