OH-58 Block II
The OH-58 Block II is the fastest-fielding, lowest-risk, and lowest-cost solution to achieve 6,000 ft / 95°F performance with the Kiowa Warrior. The high/hot performance that our soldiers need can be attained with propulsion and drive train upgrades to the existing Kiowa Warrior platform. Building upon F model Cockpit And Sensor Upgrade Program (CASUP) improvements by adding a new engine, transmission and rotor systems, along with the latest condition-based maintenance (CBM) technologies, the OH-58 Block II will provide greater capability, higher performance, increased safety, and even greater operational readiness.
