The submission says that such images were published “deliberately” - in order to convey to foreign colleagues information about what weapons Russia can use in Syria.
The publication notes that the C-400 "Triumph" systems pose "a serious threat to NATO aircraft that perform antiterrorist tasks." A statement is made that for C-400 there is no such thing as stealth technology, and therefore C-400 is “threatened” not only by F-15 and F-16, but also by F-22 Raptor.
As a kind of evidence of the presence in Latakia C-400 "Triumph" the British media gives this photo.

The official representative of the Ministry of Defense Igor Konashenkov called the statement of the British media about finding C-400 in Latakia disinformation.
Igor Konashenkov:
Before you frighten the British and the world by locating our C-400 anti-aircraft missile system here, you had to see what it was like at least in Wikipedia or on the website of the Russian Defense Ministry
