Stage Guide
The route from D to C is one-way only (you can not move from C to D). All compass spins in this stage are random. Keep trying if you're getting detoured to the maelstrom. Do note that F has heavy cruisers and the boss node has a battleship.

Stage Guide
After playing this stage once you may notice that standard aircraft carriers kind of hurt. For now your only countermeasures are to pick up a few heavy cruisers in this stage or 1-3 and train them up or just trying to craft battleships for doing the same just to push through with firepower and armor. Otherwise you can try to build your own aircraft carrier and put on fighters of your own to shoot down enemy aircraft. Note that this last suggestion will also help in completing the Akagi quest (A11 and B10).

Stage Guide
This is the first map which has branching rules, the first map with a boss HP bar requiring multiple completions, and some very powerful Flagship and Elite enemies if a poorly formed fleet is sortied. As it is an Extra Operation, it is not required to continue on to World 2. This is a complete submarine map, unless your fleet composition is wrong and you go off-course. Clearing this map gives you a bonus medal and a boost to your admiral points for ranking purposes. At the beginning of each month, the boss HP bar will be reset, thus allowing you to obtain the medal and bonus points again. (If the month has reset and the boss bar didn't regen for you, get a new API link if you're using one, or simply refresh the game if you don't)


 * The enemies on the map are scaled to your HQ level, which means that the enemy may rank up when you hit a certain HQ level. Nodes power up at levels 40 and 80.
 * Defeating the boss on this map will give you a large amount of HQ exp. This means if you don't want to inflate your HQ level (which causes you to see stronger enemies) then consider retreating on C node.

Tips

 * You are required to sink the boss submarine 4 times to clear the map.
 * A good place for players with an HQ Level below 80 to level their DDs and CLs. For details, refer to the levelling guide.
 * Recommended composition: 1 CVL 1 BBV 2 CL. This will guarantee that you will reach the boss node. You may replace any number of CLs with DDs or Katori if you wish.
 * Taking more than 4 ships will not allow you to reach the boss node.
 * 1 BBV is recommended as it can equip seaplanes to hit subs while allowing you to enter the 2nd shelling phase.
 * 1 CVL is recommended since it can equip Saiun to prevent T-cross disadvantage a.k.a. Red T, which can make killing the boss almost if not downright impossible. The only downsides of a CVL are its low armour and ASW damage, but the latter can be rectified with the appropriate planes.
 * It's possible to replace the CVL with a CAV or AV, but it's not advisable to do so without good equipment. An AV can equip depth charges, a CAV has better armour and can equip seaplanes to hit subs, but neither of them can equip Saiun to prevent the occasional Red T.
 * Ideal equipment recommended for HQ level over 80 (not including historical rewards that are currently unobtainable):
 * Type 3 Depth Charge (+8 ASW)
 * Type 3 SONAR (+10 ASW)
 * Ka-type Observation Autogyro (+9 ASW) (Stock equipment of Akitsu Maru Kai)
 * Type 3 Spotter/Liaison (ASW) (+7 ASW) (Stock equipment of Akitsu Maru Kai)
 * Zuiun (634 Air Group) (+5 ASW) (Stock equipment of Tone/Chikuma Kai-2; D10 & D12 Quest reward)
 * Zuiun Model 12 (+5 ASW) (Stock equipment of Fusou/Yamashiro Kai-2,)
 * Prototype Seiran (Mountain Haze) (+6 ASW) (Stock equipment of I-401 Kai)
 * Tenzan Model 12 (Tomonaga Squadron) (+6 ASW) (F13 Quest reward, requires Hiryuu Kai-2)
 * Suisei (Comet) (Egusa Squadron) (+5 ASW) (F14 Quest reward, requires Souryuu Kai-2)
 * Type 97 Torpedo Bomber (931 Air Group) (+7 ASW) (Stock equipment of Ryuuhou Kai)
 * Ju 87C Kai (+5 ASW) (D6 & D7 Quest reward)

Stage Guide

 * World 1-6 is unlocked by clearing World 1-5. The monthly map resets also locks 1-6 again, thus making it necessary to clear 1-5 every month to gain access to 1-6.
 * The monthly map reset is conducted at 2359h JST on the last day of the month. It is necessary to refresh the game/reload the API in order to view the reset lock - if you complete it after this time limit, you will not receive any map-clear reward aside from the resources and experience from the nodes themselves.
 * The following ship types are not allowed on this map: (F)BB, CV, CLT, SS(V)
 * You may bring: BBV, CA(V), CVL, AV, CL, DD, Akitsumaru, Katori, Akashi, and Taigei.
 * NOT RECOMMENDED TO USE BBV, CA, CVL AT ALL.
 * Reaching node N 7 times clears the map, rewarding you with 1 Present Box & 75 ranking points. No medal.
 * If you reach Node N again after clearing the map, you will only be rewarded with either 50, 70 or 100 fuel, ammo, steel or bauxite until the bar is reset on the 1st day of a new month.
 * There is no Boss Battle in this map. Instead you will receive a random amount of resources of either Fuel, Ammo, Steel, or Bauxite at the last spot without any battle thus technically it is not a Boss Node and instead a Huge Resource Node.
 * Because Node N, the node after node B and D is the Ending Huge Resource Node, you may advance to the node with a Heavy Damaged Ship after defeating the enemy fleet in node B or D, as you won't be facing any enemies in node N.
 * Using 3 CL 3 DD or 4 CL 2 DD will take you to node C.
 * Using BBV, CA, CVL will take you to node C or K, which will take you to a route where there are very difficult enemies such as Flagship Wo-class, Flagship Ru-class waiting for you. Line Ahead Submarines also exist.
 * Node A is empty node. No Battle.
 * Node E is Submarine Node with Echelon formation. Because this node is so minor in nature, bringing Anti-Submarine equipments is not required.
 * Double-arrow nodes (D, F, L) are Carrier Task Force battle nodes like those in the Summer 2014 Event. On those nodes only two Aerial Combat phases occur during day battle. Only CV/CVL participate here, unless night battle is pursued (Originally ill-advised, but an April 23, 2015 update promised to make this more feasible, still its degree is unknown)
 * Having Anti-Air Cut-In equipments on your ships is highly recommended to survive node F.
 * You can bring either 2 AV or Akitsu Maru + CAV to have a chance at getting a B rank on Node F.

Tips
Recommended Fleet Compositions: Recommended Equipment:'
 * Node E is a good place for Players above Level 80 HQ to do their Daily Quest Bd8 (Sink 6 Submarines) and Weekly Quest Bw5 (Sink 15 Submarines).
 * A - E - G - F - B - N (Huge Resource Node)
 * 1 CL + 5 DD (Ensures movement from Node G to F). Since only CV/CVL participate during day battle in aerial battle node F, the rank for this node will be usually D (i.e. loss). This can be avoided by pursuing night battle, but, apparently enemy evasion is increased for aerial battle nodes and also there is the risk of a ship receiving great damage before the final battle node B (which has some rare drops if cleared at S rank). Therefore, usually it is probably better to just accept the defeat on node F. One should still keep their sortie ratio in mind when doing this (>75% for event participation), though running 1-1 a couple of times should be enough to return to a 'safe' ratio in case of risk.
 * 4 DD + ( 2 AV or 1 CAV + 1 LHA or 1 CL + 1 AV or 1 CAV + 1 AV) (Has a chance to go from Node G to K. The advantage with this composition is the possibility of a B rank at Node F.) (Using Akitsushima could help meet node J's LoS requirement and thus give a higher chance to finish the run even if get diverted away from AEGFBN route)
 * Set at least some of your destroyers with equipment that would allow them to use Anti-Air Cut-In.
