The Tetraedr Scientific Industrial Unitary Enterprise has unveiled a number of upgrades for surface-to-air missile systems.

The Minsk, Belarus-based company is offering radar and missile upgrades, concentrating on the Almaz S-125 (SA-3 Goa), and Antey Osa-1 (SA-8 Gecko), although it is also offering modifications for the Fakel S-75 Dvnia (SA-2 Guideline), Antey Krug (SA-4 Ganef), Antey Tor (SA-15 Gauntlet) and Tula KBM Pantsir S1 (SA-19).

The upgrade uses new guidance, sights, and command and control systems but retains existing missile bodies and propul-sion systems.

The company says the changes cut reaction times by 50% and improve minimum and maximum engagement ranges while allowing low-flying cruise missiles to be targeted.

Tetraedr says its new guidance system reduces dynamic errors by 90% and increases the hit probability by 50-80% while changes to the radar increase detection range by 100-200%.
