Summary:An extended range projectile (10) includes an outer shell (12), a center projectile body (14) axially moveable from a stowed position to a deployed position within the outer shell, and a pusher plate assembly (16) variably locked to an aft end of the outer shell. The pusher plate assembly includes a check valve disposed at an aft end of the pusher plate assembly, the check valve being moveable from a closed position to an open position. In the open position of the check valve, the check valve is configured to permit entry of a gunfire pressure, created in a barrel of a gun from which the extended range projectile is configured to be projected, into the pusher plate assembly such that, when the extended range projectile exits the barrel, the gunfire pressure moves the center projectile body from the stowed position to the deployed position and propels the extended range projectile.
