I wonder how large these missiles are and if they are in any way comparable to the Chinese YJ-91. Seems to me that they might be a bit larger than the 91, although definitely not YJ-12-sized.
This also raises the question of why there are no air-launched variants of the YJ-12 that could be carried by fighters. Having fighters as your AShM platform dramatically increases their survivability and complicates the enemy's defense strategy. The JH-7B could carry up to two YJ-12s but that project has been axed. Come to think of it, the PLAAF/PLANAF currently has no fighter-borne supersonic AShMs in its inventory. Even the HD-1 missile system has been offered to Pakistan and Egypt for use on their fighters.
This missile, along with the Yun Feng, Wang Chien, and (to a lesser extent) the HF-IIE, represent the biggest threat to the success of a Taiwan operation and possibly to Chinese assets in mainland China itself.
The HF-III is believed to be developed from a US target drone (not the Coyote), the name of which is slipping my memory. Form follows function.It looks suspiciously similar to YJ-12.
