The X-49 is an experimental compound helicopter developed to demonstrate the ability to increase the speed of existing
helicopters to 200kt (360km/h).
In October 2000, a demonstration contract was awarded by the US Naval Air Systems Command to Piasecki Aircraft.
A Sikorsky YSH-60F was modified as a testbed for the
Vectored Thrust Ducted Propeller (VTDP) system.
During 2004 the VTDP program (now X-49A) was transitioned from the US Navy to the US Army's Aviation Applied Technology Division.
