'''Flagship Protection''' is when a non-flagship protects the flagship from being targeted by receiving the attack instead. When activated, a "curved shield" animation plays in front of the flagship's banner.
+
* Activation rate is determined solely by the selected formation. If activated, a ship with HP above Minor Damage ({{lang|ja|小破}}) is randomly selected to be the protector.
+
** If no ships are above Minor Damage, flagship protection cannot activate.
+
** Having more ships above Minor Damage does not increase the rate.
+
* It may activate on any type of attack, including shelling, torpedo, ASW, airstrike, and support.
+
* Submarines do not protect surface ships and surface ships do not protect submarines.
+
* [[Installation]]s cannot perform protection, and cannot receive protection if they are flagship.
+
* In [[Combined Fleet]]s, the escort flagship does not receive flagship protection.
