Analysis

Kaiboukan No.4 Kai

Priority: Low

Destroyer escorts, also known as kaiboukan, are cheap, mass-produced vessels focused on ASW, and that's what they should be used for.

However, they are a poor fit for surface combat, so make sure not to expose them to enemy surface ships too much.

Furthermore, they can be used for an unique kind of Modernization that can increase HP, ASW and Luck.

Refer to the corresponding page for details on that.

Kaiboukan No.4 (Yottsu) has the doubtful honor of being the least useful ship in the entire game, having the same consumption as other ships of the same type with one equipment slot less.

The reason her remodel isn't listed as Very Low is that with two slots she can actually do ASW work decently and therefore be deployed if one really insists to do so.

No further remodels have been implemented for her yet (as of November 2020).

Recommended Roles

• ASW
