The plan is to go to a preliminary design review this summer and a critical design review next summer, with first delivery in late 2016. From there, intermittent tests will lead to the limited user tests in late 2018. The fielding is not going to be complete until the mid-2020s.

The matter of wheeled versus tracked vehicles is not entirely settled, as other studies are ongoing.
