| Note = '''5 [[OASW]] (with 4 being strong)''' is the absolute minimum requirement to stabilize the route. Fewer than 5 will increase the retreat rate.

*A "strong OASW" is defined as a setup utilizing [[ASW Synergy]] ([[Small Sonar]] + [[Depth Charge]]).

*It is important to keep in mind that most retreats here are due to submarines. Especially at '''HQ 120''' where 7-4 is mutated into its last scaling stage, changing the enemy patterns and stats such as below:

*It is important to keep in mind that most retreats here are due to submarines. Especially at '''HQ 120''' where 7-4 is mutated into its last scaling stage, changing the enemy patterns and stats, making farming more difficult if lacking enough strong OASW. An example of these changes are as the following:

**Node J always has 3 {{Enemy/Link|Submarine So-Class Flagship|text=So-Class Flagship}}

**The boss gains more armor

[[CVE]] should be either Zuihou or Ryuuhou for OASW. While not as strong as the strong OASW setup above, they can still sink some weaker submarines on the way.<br>
