Just now I did a brief survey. Apparently until this Chinese report, YJ-
62 was known to launch from a ship. See
C-602 http://en.wikipedia.org/wiki/C-602
(C-602 is export name for 鹰击 Yingji-62; used as anti-ship and land attack)
.
Despite a few earlier photographs (released by China of course) of YJ-62 at
the very instants of firing on a land launcher,
Apparently the 解放军报 report is the first to declare YJ-62 missiles can
fire from a land launcher to target a moving ship--and succeed.
