I've noticed on a lot of Japanese army aircraft, and some Russian also, that they have a fixture on the end of the propeller hub for a starter truck to back up to the aircraft and start the engine.
Did these aircraft have other means of starting the engine, like hand cranked inertia staters ? Or was the Hucks all they had ?
If it was only Hucks or nothing, I imagine sudden surprize air attacks really turned some IJA airfields into cunfusion, with a few starter trucks trying to start a lot of aircraft .
