The CM-302 missile exhibited at Airshow China 2016 is being marketed for export as "the world's best anti-ship missile", according to Chinese news media.
The missile's manufacturer, state-owned China Aerospace Science and Industry Corporation (CASIC), reportedly justifies the claim on the grounds that the missile is supersonic throughout its flight, can be launched from air, land, and naval platforms, and used in a land attack role.
A report published by the China Daily newspaper also confirmed that the CM-302, which was allegedly one of the exhibits to have attracted the most enquiries at this year's air show in Zhuhai, is closely related to the YJ-12 supersonic anti-ship missile (ASM), which is in service with China's armed forces.
The report states that the CM-302 has a range of 280 km, a warhead of 250 kg, and a 90% probability of hitting its target. CASIC claims that the missile is effective against large warships, such as aircraft carriers and destroyers, with a single missile having the capacity to disable a 5,000-tonne warship.
While the news report provides few details about the CM-302's propulsion and flight profile, it said that the missile sea-skims for most of the flight and manoeuvres during the terminal phase to defeat the defensive weapons of ships.
Previously published reports about the YJ-12 indicate that the ramjet-powered missile achieves a mid-course speed of Mach 1.5-2, accelerating to Mach 3 or higher during the terminal phase of the flight.
The missile is guided by satellite navigation - specifically by China's BeiDou Navigation Satellite System - to a target location, which can be updated by data link. Terminal homing is driven by an active radar seeker.
Assuming the missile's physical characteristics are similar to those of the YJ-12, the CM-302 is likely to be a large missile of around 7 m in length, 0.6 m diameter, and with an estimated weight of around 2,000-2,500 kg.
