9K33 Osa

A Soviet-era, fully self-contained short-range air-defense vehicle combining radar and missiles on a single amphibious 6x6 chassis, once widely fielded for divisional air defense. Older Osa systems remain in reserve and combat use by Russia and Ukraine alike.

In service since 1971 · 25 operator countries

Full specifications

Performance

Speed, range, altitude and engagement capability.

Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.: 2.4 Mach

Stronger than 19% of air-defense systems
Engagement range Maximum distance at which an air-defense system can intercept targets. Higher covers more airspace.: 10 km

Stronger than 14% of air-defense systems
Engagement altitude Maximum target altitude the system can reach.: 5,000 m

Stronger than 12% of air-defense systems
Simultaneous targets Number of targets the system can engage at once. Higher resists saturation attacks.: 2

Bottom 6% of air-defense systems

Firepower

Armament, payload and guidance.

Main armament Primary weapon: main gun, cannon or missile type.: 9M33 interceptor missile
Warhead Warhead mass. Heavier generally means larger effect radius, at the cost of range.: 15 kg

Stronger than 32% of air-defense systems
Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable.: Fragmentation
Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire.: Radio command guidance

Sensors & avionics

Radar, sensor suite and datalinks.

Radar Primary radar. AESA (active electronically scanned array) is the current state of the art.: 9S32 Land Roll acquisition/tracking radar
Radar range Published detection range against a typical fighter-sized target. Higher sees first.: 40 km

Stronger than 19% of air-defense systems

Program

Cost, production scale and operators.

Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.: 1,200
Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 25
