The Type 1936C ships were derived from the hull of a Type 1936A destroyer but featured upgraded turbines borrowed from reconnaissance cruisers for greater power. The main armament consisted of six 128 mm dual-purpose guns mounted in three turret mounts. A total of six ships of this class were ordered, but none of them were ever launched. Z-46 was laid down in 1943 at the Deschimag shipyard, but her construction faced significant delays due to material shortages and frequent Allied bombing raids.
