A russian amphibious missile launcher. NATO code name SA-8 Gecko. The SA-8 was the first mobile air defence missile system incorporating its own engagement radars on a single vehicle. Engagement range for the early versions was approximately 2-9 km and engagement altitudes of between 50-5000m. The 9K33 Osa/Romb / SA-8 Gecko Surface to Air Missile system was developed for PVO-SV (Soviet Army Air Defence) and other Warpac Armies to provide a short range terminal point defence capability for armoured and combined arms divisions on the move. Key requirements included high levels of autonomy for the system, an amphibious TELAR vehicle, and the capability to engage targets at altitudes between 50 and 100 m, up to 5 km, at closing speeds of up to 500 m/s, at ranges between 0,8 to1 km out to 8-10 km.
