CCTV disclosed a PLA H-6G bomber launched an anti-ship cruise missile from air. The YJ-12 is perhaps China’s most deadly antiship missile. The YJ-12 is usually air launched, can travel at a speed of around Mach 4 at a range of 400km.
A saturation attack by YJ-12’s fired at long range would pose a grave threat to American carrier strike groups; once the wave of sea-skimming missiles appeared over the horizon and was detected by ships’ own sensors, they would only have some 45 seconds to engage before impact and if there were enough, short range defenses would be overwhelmed. Given that fighters such as the Su-30MKK and J-11B have a combat radius of about 1,500 km, equipping them with the YJ-12 gives them a potential strike range out to 1,900 km (1,200 mi; 1,000 nmi). The U.S. Navy’s counter is to use the Cooperative Engagement Capability to detect and destroy the YJ-12’s launch aircraft with SM-6 missiles and fighters at long range before they can be fired。
It has been test-launched from Xian H-6 bombers[9] and will be fitted on the JH-7B.[1] Reportedly, they may also be launched from the J-10, Su-30MKK, the J-11, and J-16.(fro wikipedia.org)
The above shows YJ-12 has capabiity of terminal trajectory correction before hitting the target
