The opening anti-submarine attack (OASW) can be performed by a ship that meets the minimum required visible ASW stat and necessary equipment requirements. In the case of a combined fleet, only the escort fleet can participate in the OASW.

  • If several ships fulfill the requirements, then they all can perform preemptive attacks, each attacking a random submarine in the enemy fleet. The firing order is determined by the range order, similar to the First Shelling Phase. The order for ships of the same range is random.
  • The damage follows the usual ASW formula and is affected by the usual modifiers (formation, engagement, health, ammo), as well as equipment improvements.

OASW Level Table

The following tables show how much base ASW is needed (in form of required ship level) to enable OASW with a given equipment setup (T4: Type 4 Passive Sonar, T3: Type 3 Active Sonar, DC: Type 3 Depth Charge Projector ASWR: Prototype 15cm 9-tube ASW Rocket Launcher).

Note: Some rare high-ASW equipment (such as Lightweight ASW Torpedo (Initial Test Model)) exist which can allow OASW more easily, but are so rare/low in number that they may not be included in these tables.
