Future Vertical Lift (FVL) is a program to develop a family of helicopters for the United States Armed Forces. Four different sizes of aircraft are to be developed. They are to share common hardware such as sensors, avionics, engines, and countermeasures. The U.S. Army has been considering the program since 2004. FVL is meant to develop a replacement for the Army's UH-60 Black Hawk, AH-64 Apache, CH-47 Chinook, and OH-58 Kiowa helicopters. The precursor for FVL is the Joint Multi-Role (JMR) helicopter program, which will provide technology demonstrations planned for 2017.
