Search for military personnel continues after Osprey crash off coast of southern Japan

Except for the assault nature of AV-22, the Ospreys used by the Marines, MV-22 , are the same in specifications, isn't it? In other words, Ospreys are all the same basically by whichever branch of forces they may be used.                                           

 And yet, it's only Yokota-based AV-22's that they grounded for safety reasons. Futenma-based MV-22's are still flying and even participating in a rescue work off Yakushima.

Which aircraft being used to rescue crashed Osprey?

That's right, send other Ospreys

The USAF version is equipped for special operations missions deep behind enemy lines. They replace the old HH-53D. It has Terrain Following Radar to permit low level flight in any weather, day or night, a FLIR, additional defensive systems, countermeasures and the like to allow operations behind enemy lines.
