Marsh Aviation at Falcon Field Airport Mesa, Arizona, was contracted to replace the Tracker’s Wright R1820-82 radial engines with Allied Signal/Garrett TPE331-15AW turboprops. US-2A 136613 was modified as the prototype and first flew on November 24, 1986, wearing the registration N426DF and marked as tanker number 180. Was tested as a fire bomber for the California DFFP as Tanker Number 180. Marsh also modified S-2A BuNo 136746, which flew as tanker 155. The success of the project led CDF to acquire 26 S-2E/G models in 1996 and convert them to turbo props. Based on the S-2E/G variant of the Tracker, they had longer fuselages and increased wingspan compared with the S-2A. US-2A 136613 Returned to Marsh Aviation.

Possibly Grumman US-2B Tracker BuNo 136436, 136480, 136510 or US-2A 136613 which were all associated with MCAS Iwakuni/Naha/Futenma around 1973, and from the flat terrain and US Marine Corps helicopters in the background – appears to be akin to those bases.
