Probably one of the hardest campaign missions in the game, some players have compared this map to Rendezvous at the Java Sea from the previous game. Primary Objectives
- Land in the water near the German U-boat.
- Sink the enemy convoy.
- Sink the sub-hunting battle group.
Secondary Objectives
- Sink all enemy ships.
Hidden Objectives
- Sink a ship by torpedoing it from both submarines.
If you obtained the gold medal in Hunt for the USS Hornet, you should have the opportunity here to upgrade to the I-400 submarine. You'll need as much help as you can for this mission, so do so. The Kaiten Carrier is completely useless as of the game's initial release. When it is patched, however, the Kaiten Carrier should be able to handle this mission almost single-handedly.
Your first objective is a simple one - land in the water near the German submarine. If you don't have the Flying Fish achievement, you'll get it now. Avoid the enemy convoy escorted by the Clemson - you'll manage to sink them later.
As you approach the German sub, you'll hear some dialogue. You'll then receive orders to land near the German sub. Head for the ocean, throttle back, and make sure your pontoons touch the water. Then pull back on the throttle, and you'll have landed. Don't worry about crashing into the German sub.
Now is your chance to get in attacks on the enemy convoy, and this is the ideal place to get the hidden objective. You outnumber the enemy escort destroyer, so perform the head-on attack to sink it quickly. Neither the Type B nor the I-400 have aft torpedo tubes, and U-580 has only one. Therefore, you'll want to avoid back attacks at all costs.
The head-on attack will prove, therefore, extremely useful when countering destroyers. A head-on attack will effectively eliminate the escorting Clemson-class destroyer. Once this destroyer is down, you can attack the rest of the convoy at your leisure. This is now the best spot to achieve the map's hidden objective. Pick a transport ship and sink it with one torpedo from your submarine, and then another from U-580.
It is best to finish the rest of the enemy on the surface. Some cannonade to the magazine or fuel will, as always, start a fire that will ultimately sink the target ship.
