The Patria ITO 90 is an all-weather short-range air defense system integrated on the Patria Pasi XA-181 6×6 armored chassis and operated by the Finnish Army (Maavoimat).
Features
- Tactical designation: ITO 90 (Ilmatorjuntaohjus 90, Surface-to-Air Missile in Finnish).
- Operational role: All-weather Short-Range Air Defense (SHORAD) system.
- Primary mission: Protect mobile mechanized units, command posts, and critical infrastructure against attack helicopters, low-altitude aircraft, cruise missiles, and unmanned aerial vehicles (UAVs).
- Tactical capability: The self-propelled 6×6 chassis provides high cross-country mobility and armor protection against shrapnel and small arms fire, enabling rapid deployment and relocation capabilities, including shoot-and-scoot operations.
