Photos of the day: HQ-6D/LY60D airport point-defense SAM

On the surface, the following photos might seem insignificant, just another bunch of PLAAF PR shots, but look closer there is a HQ-6D point-defense SAM there.  Over the years, the PLAAF has slowly replacing their old 57mm and 37mm AAAs with short-range SAMs.  It is a development that seems to have missed by many.
