The goal of this phase is to sink the New Old Submarine Princess found at {{MapRoute|V|Red}} to deplete the HP Bar and clear the map. There are surface engagements {{MapRoute|H|Red|S|Red}} and high airpower air raid {{MapRoute|I|Red}} on route, but the Boss itself is an Anti-Submarine operation. AACI is highly recommended for this route, the surface Nodes can be passed using Vanguard formation as to not sacrifice too many equipment slots that should be occupied with ASW equipment. | The goal of this phase is to sink the New Old Submarine Princess found at {{MapRoute|V|Red}} to deplete the HP Bar and clear the map.
