The body of Nathaniel A. Kibodeaux, 38, was found Sunday about 10 miles west of Mountain Home Air Force Base.
Two friends of Kibodeaux, also airmen, found his body along the Snake River near Grandview, the Mountain Home Sheriff’s Office reported.
Kibodeaux went on a duck hunting trip on Saturday. Search and rescue teams went looking for him after he failed to return.
Kibodeaux was a member of the 366th Aircraft Maintenance Squadron.
The cause of death is under investigation, but sheriff’s officials said they do not suspect foul play.
