The expectation is to buy a new family of helicopters through a competition and field the new aircraft at some point in the early 2030s, although the Army has talked about speeding up that fielding timeline to the late 2020s.But first the Army plans to demonstrate Joint Multi-Role (JMR) air vehicle capability at a 2017 flight demonstration in order to help the service fully define requirements for the Future Vertical Lift (FVL) program.
