On display at the Steven F. Udvar-Hazy Center, National Air and Space Museum. The Okha 22 was an improvement over the Okha 11 that had a range of only 37 km. After a number of Okha 11s were lost along with their carrier G4M2e Betty bombers on several sorties, it became necessary to extend the range to 130 km by installing the Hitachi Tsu-11 hybrid motor-jet engine. This is the only surviving Model 22.

The Ohka 11 was required to be launched within 37 km (23 mi) of the target, making them very vulnerable to defending fighters. The Model 22 was designed to overcome the short standoff distance problem by using a thermojet engine, the Tsu-11. This engine was successfully tested and 50 Ohka 22s were built but never used operationally. This is the only surviving example (marked '59' aft of the blossom) and is on display at the NASM Udvar-Hazy Center.
