Which aircraft is known as the Sea Ranger?

The aircraft known as the Sea Ranger is the TH-57. This helicopter is primarily used in the United States Navy for training purposes, particularly for training naval aviators in rotary-wing flight. The designation "TH" indicates that it is a trainer helicopter, and “57” references the model year of its introduction.

The TH-57 is a variant of the Bell 206 Jet Ranger, which is known for its reliability and versatility. As a training aircraft, it is crucial in developing the skills necessary for pilots before they transition to more complex helicopter variants or operational roles. It's worth noting that other helicopters, such as the UH-1N, MV-22B, and VH-3D, serve different functions within the Navy, including utility transport and presidential transport, but they do not share the "Sea Ranger" nickname associated with the TH-57.
