Sosna-U

The Sosna-U is a Russian (formerly Soviet) short-range air defense missile system (SHORAD). It is designed to protect military units and installations from air attacks by helicopters, airplanes, cruise missiles, and precision-guided munitions. The Sosna-U is an upgrade of the earlier Sosna system, featuring improved range and accuracy.

Key features of the Sosna-U include its ability to engage targets while on the move, its resistance to electronic countermeasures, and its dual guidance system. The missile uses both laser beam riding guidance and a thermal imaging seeker for terminal homing, providing enhanced accuracy and resilience against jamming.

The system typically consists of a combat vehicle, which includes the missile launcher, fire control system, and optical-electronic targeting system. The vehicle is usually based on a tracked chassis, providing high mobility and cross-country capability. The Sosna-U utilizes the Sosna-R missile, a two-stage solid-propellant missile designed for high speed and maneuverability.

The Sosna-U is intended as a replacement for older systems like the Strela-10. Its development and deployment reflect the ongoing modernization of Russian air defense capabilities.
