Luckily i have an old savegame with this quest unlocked. This quest seems to be part of the questline to unlock Z1.

First you need to do the first 3 expeditions in 西南海域

The first one needs: 1 light cruiser and 3 DDs, the second one needs: a full fleet with atleast 3 CA and 1DD, the third one needs: 3SS (wikiwiki states, flagship lvl 17?, comined fleet level 30)

Then you unlock the expedition for this quest. It requires 4SS (wikiwiki states, flagship lvl 17?, comined fleet level 62?)
