Russia Puts 4th S-400 Air Defense Regiment on Combat Duty

The fourth regiment armed with S-400 Triumf air defense systems will be officially put on combat duty in Russia’s Far East on Thursday, a spokesman for the Eastern Military District said on Wednesday.
“The official ceremony will be held on August 16,” the official said.
The regiment, which is deployed near the port city of Nakhodka in the Primorye Territory, joins other S-400 regiments deployed in the Moscow Region and in the Baltic exclave of Kaliningrad.
By 2020, Russia is to have 28 S-400 regiments, each comprised of two battalions, mainly in maritime and border areas.
The S-400 Triumph long- to medium-range surface-to-air missile system can effectively engage any aerial target, including aircraft, unmanned aerial vehicles, and cruise and ballistic missiles at a distance of up to 400 kilometers (250 miles) and an altitude of up to 30 kilometers (18.6 miles).
