 Ukrainian soldiers destroy Russian OSA air defense system with Himmars. Ukrainian soldiers with Himmars destroyed the Russian OSA anti-aircraft missile system in the southern direction according to the Special Operations Forces of Ukraine. Reportedly, while conducting reconnaissance in the southern direction, the crew of the 73rd Marine Center of the Special Forces, despite poor visibility, discovered the OSA anti-aircraft missile system that the enemy used against Ukrainian troops. The Special Operations Forces operators adjusted the Himmars fire of the missile and artillery unit of the Ukrainian Defense Forces to the enemy target. As a result of the fire damage, the Russian anti-aircraft missile system was destroyed to the ground. The OSA-M is a naval SAM system of Soviet origin. It was developed to act as a point defense system against aircraft and inbound anti-ship missiles. Over time, it was upgraded for more effectiveness against low-flying targets. The OSA-M is derived from the land-based 9K-33 OSA self-propelled SAM system. There is a 70% commonality in missile design and guidance systems, whereas the land-based 9K-33 is one of the first self-propelled SAM systems where radars, operators and missiles are on the same vehicle, the OSA-M has a more modular layout.
