Overview
A variant of the Changjian-10 (CJ-10) land-attack cruise missile (LACM), the CJ-20 is an air-launched LACM capable of carrying both conventional and nuclear warheads.[i] Still under development, U.S. Air Global Strike Command estimates the nuclear-capable variant will be operational by 2018.[ii] Although the weight and yield of the nuclear CJ-20 is unconfirmed, its CJ-10 predecessor possesses an estimated 400kg payload and yield likely ranging from 20 to 90 kT.[iii] Approximations of the CJ-20’s range vary, and include distances up to 2,200km.[iv]
Strategic Implications
Designed to be launched from the H-6K strategic bomber, which has a 3,700km combat radius and can carry up to six cruise missiles,[v] the CJ-20 will significantly enhance the PRC’s long-range nuclear strike capabilities when fully developed. Likely capable of reaching Japan, Guam, and northern Australia, the CJ-20 will be a crucial addition to the PRC’s anti-access/area denial and first-strike capabilities.[vi]
