TH-57 Sea Ranger Helicopter

The TH-57 is a derivative of the commercial Bell Jet Ranger 206. Although primarily used for advance training in the rotary-wing (helicopter) pilot syllabus; these aircraft are also used for photo, chase and utility missions.
The Jet Ranger was initially designed to compete in a U.S. Army light observation helicopter competition. Bell lost that competition but the 206 was commercially successful. The TH-57 Sea Ranger provides advanced Instrument Flight Rules training to several hundred aviation students a year at Naval Air Station Whiting Field in Milton, Florida. The current TH-57B was introduced in 1981 and the TH-57C was introduced in 1982.
