The initiator of the beginning of such a project was the US Navy, which needed high-quality and effective air equipment used to detect and destroy submarines and enemy submarines. Moreover, due to the peculiarities of the design of the aircraft of this model, the aircraft Bell HSL could also be used for other purposes, for example, for performing search and rescue operations, transporting people and heavy loads on its board.

The first test trials helicopter Bell HSL model were conducted aircraft manufacturers of the company «Bell Helicopter» in 1953 year, however, a number of technical flaws, aircraft control was very difficult, as a consequence, the development continued, and only 1957 year the aircraft was officially presented.

The helicopter gave very effective in terms of its operational capacity, and therefore, in the naval forces of the USA 50 aircrafts of this model were delivered, which operated until the end of 70-ies of the last century.
