A CZ-6 rocket can technically be a multiple independently targetable reentry vehicle (MIRV) for up to 20 missiles, each of which is capable of being aimed to hit one of a group of targets. This offers a distinct advantage over multiple reentry vehicles (MRV), which can carry several warheads which are dispersed but not individually aimed.
The Dongfeng-41 (DF-41, CSS-X-10) is a Chinese nuclear solid-fueled road-mobile intercontinental ballistic missile.
It has an estimated operational range of between 12,000 km to 15,000 km. This could make the DF-41 the world's longest ranged missile, surpassing the range of the US LGM-30 Minuteman which has a reported range of 13,000 km. It is believed to have a top speed of Mach 25, and to be capable of MIRV delivery (up to 10). China had test-launched a DF-41 using multiple reentry vehicles for the first time on 13 December 2014.
A Long March 5 will be a larger version of the Long March 6. Long March 5 (LM-5, CZ-5, or Changzheng 5) is a Chinese next-generation heavy lift launch system that is currently under development by China Academy of Launch Vehicle Technology (CALT). Currently, six CZ-5 vehicle configurations are planned for different missions, with a maximum payload capacity of 25,000 kg to LEO and 14,000 kg to GTO.
