9M33 Osa

The 9M33 Osa is a Soviet short-range surface-to-air missile family developed for both the land-based 9K33 Osa and the naval Osa-M system. It is a command-guided missile family with early land-based and naval variants, later canistered and improved versions, and a compact design sized for self-propelled and shipborne point-defense launchers.

Sources describe it as a radio-command guided missile carried in a launch tube, with a booster stage that accelerates the missile to high speed before the sustaining section continues toward the target. The family is associated with the 2K22 Tunguska and related naval systems.

In the 2020 Nagorno-Karabakh war it appeared on the Armenian and Artsakh side as legacy area air defense, but reporting from CSIS and Oryx shows it was vulnerable in a battlespace dominated by Azerbaijani UAVs and loitering munitions.
