Improvement of the S-92 was initially declared in 1992 when Sikorsky revealed a mockup of the new helicopter. In 1993 however Sikorsky delayed propelling the S-92 because of the global helicopter market downturn and rather started hunting down worldwide danger imparting accomplices. By 1995 Sikorsky had framed its Team S-92 gathering and formally propelled the S-92 at that year's Paris Airshow.
