We study the dynamics of vortices in strongly disordered d0ex0ex=0ex0ex2 Josephson junction arrays and superconducting films driven by a current. We find a dynamic phase transition in vortex flow at a current Iₚ>Ic. Below Iₚ there is plastic flow characterized by an average-velocity correlation length scale ξᵥ in the direction of motion, which diverges when approaching Iₚ. Above Iₚ we find a moving vortex phase with homogeneous flow and short range smectic order. A finite-size analysis shows that this phase becomes asymptotically a liquid for large length scales.
