Retired US officer Eastwood named Poseidon and S-400 Russia's most dangerous weapons

“This weapon (the Poseidon unmanned underwater vehicle -

) is scary because it can be aimed at US cities on any coast.

Russia plans to launch Poseidon from its K-329 Belgorod submarine, Eastwood wrote.

The Russian military can use the S-400 Triumph air defense system not only to destroy enemy manned aircraft, but also against cruise and ballistic missiles at a distance of up to 250 miles, he said.

Among other dangerous types of Russian weapons, Eastwood noted the Pantsir S-1 anti-aircraft missile and cannon system (ZRPK), the Mi-28NM attack helicopter and the Yars missile systems.

Earlier, National Interest columnist Mark Episkopos spoke about the prospects of a threat to the American carrier strike group from Russian weapons.

According to him, the Russian Zircon missile could pose a threat to an aircraft carrier strike group of the US Navy.
