North Korea displayed a system closely similar to the S-400, with many new products presented at the parade marking the 75th anniversary of the founding of the Democratic People’s Republic of Korea.
The new air defence system shown in the parade (whose name has not been released) is very reminiscent of the Russian S-400 long-range air defence system. Mobile radars have been shown with it, but it is not known whether the Korean system uses external radars operating in different ranges, as does the S-400, or operates a simpler standard detection system, like the American Patriot. It is also unclear whether the North Korean missiles are capable of dual guidance, heat-seeking and radar guidance .
Given that the Russian S-300V4 and S-400 are capable of shooting down targets at a distance of about 400 km, and the Chinese HQ-9B missile at about 300 km, the new Korean system has a range of 250 km.
