Satellite imagery released by military enthusiast shows Soviet-era S-300PT surface-to-air missile system at the military range in the United States.

Enthusiast posted imagery of surface-to-air missile system on social media that looks like elements of the Soviet-designed S-300PT system.

A 30N6 fire control system and semi-trailer arrangements of 5P85 Transporter Erector Launchers (TEL) have been seen in satellite imagery of the U.S. military range. All these vehicles are part of the S-300PT surface-to-air missile system.

S-300PТ system is designed for the defensive purpose of administrative, industrial and military buildings and objects against all kind air attacks.

The S-300PT system was first deployed by the Soviet Union in 1979, designed for the air defense of large industrial and administrative facilities, military bases, and control of airspace against enemy strike aircraft. The project-managing developer of the S-300 is Russian Almaz corporation which is currently a part of “Almaz-Antei” Air Defense Concern.

According to Air Power Australia, the missile of S-300PT deployed and handled in a sealed cylindrical launch tube/canister, with a cold start gas generator used to eject the missile vertically before its motor was initiated. The 5P85 TEL was a semi-trailer arrangement, with the forward booms splayed when deployed as stabilisers. The four launch tubes were mounted on a hydraulically elevated frame, retained in later TEL designs.

The U.S. military commonly practices air assault with Russian-style air defense systems during training exercises. It uses styled or real combat vehicles and air defense systems to add extra realism to various exercises.
