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.
