In late July it was reported that canisters like those of the DH-10 land-attack cruise missile (a Tomahawk-type weapon) were on board a Chinese naval test ship, presumably as a preliminary to surface-vessel deployment in this form. The DH-10 reportedly is based on the Russian Kh-55/65 (AS-15), an air-launched cruise missile developed in the 1980s. In that form it is a long-range turbofan-powered missile (a range of 2,500 km—about 1,350 nm has been quoted) with either a nuclear or conventional payload, the latter typically credited with a 410-kg warhead.
