### Abstract

We consider the three-dimensional incompressible Navier–Stokes equation on the whole space. We observe that this system admits a $$L^\infty$$ L ∞ family of global spatial plane wave solutions, which are connected with the two-dimensional equation. We then proceed to prove local well-posedness over a space which includes $$L^3(\mathbb {R}^3)$$ L 3 ( R 3 ) and these solutions. Finally, we prove $$L^3$$ L 3 -stability of spatial plane waves, with no condition on their size.
