In this paper, we prove the global existence of analytic solution for 3D anisotropic Navier-Stokes system with initial data which is small and analytic in the vertical variable. We shall also prove that this solution will be analytic in the horizontal variables soon after t > 0. Furthermore, we show that the ratio between the analytic radius, Rh(t), of the solution in the horizontal variables and √t satisfies limt→0+ Rh(t) √t = ∞.
