Spring 2015 Event

The Spring 2015 Event Order! Operation 11 [発令！第十一号作戦] started on the 28th of April and ended on the 18th of May. The event is based on the planned Japanese Operation 11.

Like the Winter 2015 Event, it has selectable difficulties: Operation A (Hard), Operation B (Medium), and Operation C (Easy). This difficulty will be 'locked in' after you complete a map, and your choice of ships is frozen for several maps. This is a long (6 map) event, and though the maps were foretold to be relatively difficult as compared to previous events, the overall response has been that they are rather easy.

Please consider filling out an event report. You can see all of our collected data so far here.

New content

1. New Ships
   • Two Italian BB sisters from the "main force" will be some of the drops for the event, from the Littorio class.
     • Littorio, who remodels into Italia, can be found from clearing E-4.
     • Roma is an E-6 random drop.
   • The new CV Katsuragi is a reward for clearing E-2.
   • Akitsushima can be found as a reward for clearing E-6.
   • Takanami drops randomly from E2, E3 and E4.
2. New Enemy Vessels
   • Harbor Water Demon, found in E-4.
   • Anchorage Water Demon, found in E-5
3. New Equipment
   • Type 2 Flying Boat
   • 381mm/50 Triple Gun Mount Kai
   • 90mm Single High Angled Gun
   • Pugliese-Type Underwater Bulkhead
   • OTO 152mm triple extended machine gun

Mechanics

Participation requirements

• Must have a 75% sortie win ratio.
• Must have 5 empty ship slots for new ships.
• Must have 20 free equipment slots.

Special Mechanics

1. The difficulty system from the Winter 2015 Event is present, with three levels: Operation A (Hard), Operation B (Medium) or Operation C (Easy).
   • However, you must have cleared at least Operation A or Operation B on the previous map to access Operation A (Hard) difficulty for the following map for E-3 and later maps.
   • The difficulty you select will affect most rewards (including experience gain and ship drops). The only exceptions are ships rewarded as map clear bonus.
   • Once you clear a map on a difficulty (besides easy), you will be locked on that difficulty.
2. The ship-locking mechanic will have full sway in this event:
   • Ships used in E3 cannot be used in E4 on medium or hard.
   • Ships used in E3 or E4 cannot be used in E5 on medium or hard
3. E2, E4, and E6 use the Combined Fleet mechanic.

E-1

Preparation for Operation No.11 【発動準備、第十一号作戦！】 Information Boss: Heavy Cruiser Ri-Class Kai Flagship Accompanied by the Light Cruiser Demon weaker variant on Hard mode's final kill. 5 kills required on all difficulties. Rewards 甲 Hard Food Supply Ship Mamiya Food Supply Ship Irako Furniture Fairy Prototype 51cm Twin Gun Mount 乙 Medium Food Supply Ship Mamiya Food Supply Ship Irako Furniture Fairy Prototype 46cm Twin Gun Mount 丙 Easy Food Supply Ship Mamiya Food Supply Ship Irako Furniture Fairy Prototype 35.6cm Triple Gun Mount Only Destroyers and Light Cruisers can be used. Sparkling is advised, as this is inexpensive with light ships.
Branching rules Node B is a non-combat Active Branching node; . Node D is a submarine node. F and C have LoS checks to reach the boss node; this is relatively low (Reports indicate that 38 or above will clear this), so equipping radars on all of your DD and a recon plane on your CL will suffice. Show/Hide Branching Rules Branching Rules Node Split Condition B C Active Branching D Active Branching C E Chance of E with 4 or more CL? Failure on LoS check to H H LoS check Failure sends to E F G 5 or more CL, or 2-5 Fall LoS Formula≤13.6 (on Hard; unknown on other difficulties) H LoS check for H. (For Hard, 2-5 Fall LoS Formula≥14.5) Failure sends to G
Tips Use a light fleet. Compositions that work: CLx2 DDx4 provides for four high-evasion DDs which have a likelier chance of dodging incoming attacks. CLx3, DDx3 could provide more firing power, however. Between the north and south routes, south is preferred (Yes, you get to choose). The north route only has one battle before the boss but the node has considerably stronger ships, such as elite and flagship CLTs. The south route has four subs in one node that come in at either echelon or line abreast, so they are relatively harmless (the flagship sub has moderate accuracy in echelon, however). The second node has very weak and easy-to-clear ships such as I-class (the DDs you clobber in 1-1 for sparkling). The sub node does not cost you ammo; only fuel. Your composition for the final kill should remain the same. Refer to this example fleet for composition and equipment suggestion.

Branching rules Using a Carrier Task Force will send you to node C at the start, while a Surface Task Force will send you to node A. Carrier Task Force seems to be slightly easier due to enemy CV-heavy nodes. Node D (on hard) has 3 BBs (including a Kai Flagship), and Node E is rather heavy on enemy CV, so if you are using Surface Task Force, you will have to pick your poison here. Node B and F are Active Branching nodes. LoS check from G to K. Show/Hide Branching Rules Branching Rules Node Split Condition START A Surface Task Force C Carrier Task Force B D Active Branching E Active Branching F E Active Branching H Active Branching G I Failure on LoS check for K K LoS Check. Failure results in I
Tips This map is full of enemy carriers, including some Standard Carrier Wo-Class Kai Flagship; you should bring 3 CV to minimize bauxite loss and defend your fleet. Equipping AP shells will make killing the Armored Carrier Princess much easier. Fleet comps that follow standard Combined Fleet mechanics should suffice.

Bagel Bay Transport Destruction Battle 【 ベーグル湾通商破壊戦】 Information Ship Locking: Ships used here cannot be used in E4 or E5 on medium and hard difficulties. Battleships (Aviation included, fast not included) and Standard Carriers cannot be used here! Boss requires 7 kills to complete on Hard (甲). Boss: Transport Ship Wa-Class Flagship Rewards 甲 Hard Pugliese Underwater Protection Bulkhead Ryuusei (601 Air Group) Medal OTO 152mm Triple Rapid Fire Gun Mount Improvement Material 4x 乙 Medium Pugliese Underwater Protection Bulkhead Tenzan (601 Air Group) Emergency Repair Personnel OTO 152mm Triple Rapid Fire Gun Mount Improvement Material 3x 丙 Easy Pugliese Underwater Protection Bulkhead Tenzan (601 Air Group) Emergency Repair Personnel
Branching rules E to J and I to J are both LoS checks. Standard LoS equipment should be enough to clear the requirement. Keep a radar on DDs. Node F is an Active Branching node. You want to pick node D if you have decently leveled ships that can survive the Light Cruiser Demon at node D. If your ships are lower level, you may want to try going south toward node I though you will suffer from lower ammo and the subsequent penalties Show/Hide Branching Rules Branching Rules Node Split Condition START A 5+SS?

B Random D E Fixed E G Failure on LoS check for J J LoS Check (2-5 Fall LoS Formula≥30) F D Active Branching H Active Branching I G Failure on LoS check for J J LoS Check
Tips Be aware of the Light Cruiser Demon in one of node D's formations. Node C is a submarine node; however, unlike other event submarine nodes, you do use up ammo at this node. Boss node has a Ta-class battleship Possible formations: CA, CAV, DDx3, CLT - Provides enough firepower to comfortably take out boss node and the DDs should have high enough evasion to mostly dodge any incoming attacks. Enemy ships mostly consist of light ships like DDs, CLs and CLTs. This formation lets you conserve your CVLs if you don't have many. Keep mind you'll likely need up to 6 CV(L)s for E4 and E5. You can use mostly lower-tier ships in this map and save your best DDs and the like (one player cleared with 3 of DesDiv6 as their DDs).

Final Battle! Ri Lanka Island Invasion 【決戦！リランカ島攻略作戦】 Information Combined Fleet Ship Locking: Ships used here cannot be used in E5 on medium and hard difficulties. You cannot use your E3 ships here (unless being on easy difficulty). Boss: Harbor Water Demon Requires 7 kills to complete on Hard (甲).

Branching rules Node F is an Active Branching node. Node E is the advised choice, as the other branch takes you first through an air battle node (I) followed by a node (K) with similar enemy makeup as node E. Show/Hide Branching Rules Branching Rules Node Split Condition START A Surface Task Force B Carrier Task Force A C LoS Check.

Tips Possible compositions: BBx2 CVx4, CA DDx4 CLT BBx2 CVx4, CA DDx3 CL CLT BBx2 CVx4, CAV CL DDx2 CLTx2 Keep two Reppuus or similar on each CV to clear all aerial superiority requirements. Boss is an installation type enemy. Equip BB's in first fleet with Sanshiki or other anti-installation type weapons; light cruisers and destroyers can greatly profit from using WG42's. Equip second fleet with anti-installation type weapons as well. Refer to this Example Fleet for composition and equipment suggestion.

Attack on Apricot Atoll Anchorage アンズ環礁泊地攻撃作戦 Information Ship Locking: You cannot use your E3 or E4 ships here (unless you're on easy difficulty). Boss requires 7 kills to complete on Hard (甲). Boss: Anchorage Water Demon Rewards 甲 Hard 381mm/50 Triple Gun Mount Kai Emergency Repair Goddess Medal Improvement Material 8x Type 2 Large Flying Boat 乙 Medium 381mm/50 Triple Gun Mount Kai Emergency Repair Goddess Medal Improvement Material 5x 丙 Easy 381mm/50 Triple Gun Mount Emergency Repair Goddess
Branching rules Node B is a maelstrom. It has a maximum of 50 fuel penalty (subject to normal reduction via equipped Radar). Node F is an aerial combat node; two rounds of bombing occur, then you get the normal choice of ending the battle or enter night-time (which proceeds as a normal night battle). Node G is a fuel supply node. Node H is an Active Branching node. Node I is a night battle, as compensation for choosing the shorter route. Show/Hide Branching Rules Branching Rules Node Split Condition START A Weighted random towards A if Fast BB≥1 and Slow BB≥1 Random with B otherwise B Weighted random towards B if SS≥1 and 0 BBV Random with A otherwise A C All else D CV(L)≥3?, OR Fleet includes Mogami and Mikuma OR Suzuya and Kumano OR Choukai and Ryuujou OR Sendai and Fubuki D F All else G Fleet contains Mogami and Mikuma ORSuzuya and Kumano OR2 from Yura, Choukai or Ryuujou OR Sendai and Fubuki F E LoS check failed for H/I H LoS check passed; Random with I I LoS check passed; Random with H H I Active Branching K Active Branching I E Failure on LoS check for N or if BB≥5 or BBV≥3 N LoS check L J (F)BB(V) + CV(L)≥5 M Failure on LoS check and fleet composition doesn't fit route to J N LoS check.
Tips Possible compositions: 2 BB, 1 CV, 1 SS, and [Mogami and Mikuma] or [Suzuya and Kumano] or [Choukai and Ryuujou] will allow for A/B→D→G→H→I→N. There is no battle on B (Fuel Maelstrom), G (Fuel Resource gain), and H (Active Branching). (F)BB x4, CV, SS - The SS will protect your fleet in the dangerous I night-battle node and even divert Anchorage Water Demon's daytime firing; suggested equipment is a torpedo and a damecon; two damecons can also be used. Double damecons will work as you might expect - damecons can activate on two separate nodes. (F)BB x2, CV, SS, Route-fixing Mogami-class pair - This setup will allow route-fixing for full damage on boss node. Equip Sanshiki on your BBs and CA(V)s to help damage the boss. Boss is an installation-type. Being sent to the maelstrom node really hurts as likely by the time you make it to the boss, your fleet's fuel will be completely depleted if you hit node F as well. Consider turning back if sent to Maelstrom depending on your resources, especially if you want to conserve. Consider sacrificing a BB/CA(V)'s daytime artillery spotting in exchange for a Radar. A radar on CV may also be useful. Refer to this Example Fleet for composition and equipment suggestion.

Relentless Operation! Across the Stevia Sea 『打通作戦!ステビア海を越えて』 Information Combined Fleet Ship-locking does not apply to this map; that is, you can use any ship you own, regardless of whether you used it in any other event maps. Boss: Battleship Water Demon Requires 7 kills to complete on Hard (甲) and 8 kills on Medium (乙)/ Easy (丙). Rewards 甲 Hard Akitsushima Medal 2x Type 2 Large Flying Boat FuMO25 Radar First Class Medal 乙 Medium Akitsushima Medal 2x Type 2 Large Flying Boat 丙 Easy Akitsushima Medal This is the only map where Roma dropable.
Branching rules Nodes E and F are Active Branching nodes. Nodes I an J are night battles. M to O is a LoS check. The route you take will determine what branching rules apply to node L; bringing a sub through the north route is not recommended. Show/Hide Branching Rules Branching Rules Node Split Condition START B Fast Speed Surface Task Force D Carrier Task Force F Mixed Speed Surface Task Force A C CLT=3 E CLT≤2 E H Active Branching J Active Branching F G Active Branching H Active Branching G I LoS check L CLT=3 or failed LoS check for I M L Failure on LoS check or SS in escort fleet Random if SS≥1 and previous node was not K? O 1 SS in main fleet and previous node was K Random if SS≥1 and previous node was not K? LoS check otherwise
Tips The Carrier Task Force mitigates damage and sends you to Node D; branching to H is recommended as the southern route contains a night battle against a torpedo squadron led by CA Ri-Class Flagship followed by a day battle against Battleship Princess, both of which can be devastating. A mixed-speed Surface Task Force sends you to node F, giving you a choice between the middle route containing Anchorage Water Demon but with an extra Roma-dropping node (K, hard difficulty only), or the northern route containing a night battle node against a Battleship Princess and a day battle against a torpedo squadron. A fast-speed Surface Task Force fleet is first sent to A ( maelstrom) then (if not sent to C) given the same choice as the Carrier Task Force. Without question, this is NOT recommended as the fuel loss will result in you evading less attacks at pre-boss and boss nodes, reducing your combat capability. For final run attempts: With equipment designed for night battle activating, the northern route is not very threatening; Battleship Princess typically will only inflict scratch damage on your ships, and no other enemy ship in that node is equipped with DA/CI setup. Thus, a mixed-speed Surface Task Force fleet going northern route usually only has to worry about pre-boss node and the boss node; it also conserves your escort fleet's strength, with the trade off being more damage to the first fleet. A Carrier Task Force fleet going through the middle route can also work. You can put 3 CLTs in the fleet in this case, so your first fleet should more likely be able to focus on the boss because your escort fleet should (ideally) clean up the other mobs. Boss node has AS on final run attempts (Aircraft Carrier Princess on Hard and Medium, Wo-Class Flagship on Easy). Node M (Pre-boss) contains an Aircraft Carrier Princess (so Hard and Medium final runs see her in back-to-back nodes). Example compositions: (F)BBx3 CVLx2 CAV, CLTx2 CL CA DDx2 (Surface) [Note that you need to be mixed-speed] (F)BB(V)x4 CA(V) CV, CL CLTx2 BB/CA DDx2 (Surface) [alt. composition] BBx2 CVx4, DDx2 CL CLTx3 (or DDx2 CL CA CLTx2) (Carrier) Consider using a shelling support expedition to assist with the boss kill. Boss does not have AS prior to last kill, so a carrier support expedition may also be useful.

現在「艦これ」運営鎮守府では、春イベント2015：期間限定海域【発令！第十一号作戦】の実装準備を進めています。最近「艦これ」に着任された提督は「丙作戦」を、歴戦の提督方は「乙作戦」、そしてより攻略難易度の高い「甲作戦」への参加も選択可能です。 #艦これ
Currently the 「Kancolle」 Operation Naval Base is working on the preparation for implementing the Time-Limited Area for the Spring 2015 Event 【Order! Operation No. 11】. New admirals can choose 「Easy」 mode, while more experienced admirals can also choose 「Medium」 and 「Hard」 modes which has a higher difficulty.

@KanColle_STAFF	[14]
【春イベ「乙作戦」「甲作戦」参加予定の提督の皆さんへ】 歴戦の提督が選択可能な「乙作戦」及び「甲作戦」は、高難易度の作戦となります。また、作戦中盤以降は各作戦海域ごとへの艦隊戦力の振り分けも重要となります。充実した艦隊戦力と戦備を持つ提督方は、参加をご検討ください！ #艦これ
「Medium」 and 「Hard」 modes are selectable by experienced admirals, are high-difficulty operations. It is also important to figure out which ships to deploy to which map from the middle point on. Admirals who have a well-rounded fleet and stockpile should consider doing so!

@KanColle_STAFF	[15]
【春イベ「甲作戦」参加予定の提督の皆さんへ】 歴戦の提督が選択可能な「甲作戦」では、第2作戦海域以降は前作戦海域を「甲作戦」または「乙作戦」で攻略していることが次作戦参加条件となります。ご留意頂けますと幸いです。 例)【OK】丙→乙→甲 例)【NG】丙→丙→甲 #艦これ
Starting with the 2nd map, the requirement for experienced admirals to choose 「Hard」 mode is to clear the previous map on 「Hard」 or 「Medium」. Please be aware of this. Example: 【OK】 Easy → Medium → Hard Example: 【Not allowed】 Easy → Easy → Hard

@KanColle_STAFF	[16]
【春イベ参加予定の全ての提督方へ】 春イベでは、全ての提督が「丙作戦」を、さらに歴戦の提督方は「乙作戦」「甲作戦」も選択可能です。どの難易度の作戦を選択しても【作戦海域突破によって邂逅できる新艦娘】は入手可能です。その他の褒賞・ドロップする艦娘・経験値などは異なります。 #艦これ
For the Spring Event, all admirals can select 「Easy」, and more experienced admirals can also select 「Medium」 and 「Hard」. Regardless of the operation difficulty, you will be able to obtain 【ships girls encountered after clearing a map】. However, ship girl drops, experience points and other rewards will differ.

@KanColle_STAFF	[17]
【最近「艦これ」に着任された提督の皆さんへ】 春イベがもうすぐスタート致します。開催期間は約20日間ありますので、いきなりイベント海域に飛び込まず、通常海域での艦隊戦力の充実、練度の向上も併行して行って頂けると攻略の鍵がきっと見えてきます。どうぞよろしくお願い致します！ #艦これ
The Spring Event is almost here. The event period will be about 20 days, so keys to clearing the maps will include (a) don't jump right into event maps, (b) rounding out the fleet's operational capability in regular maps, and (c) increasing the ship's experience. Please keep that in mind!

@KanColle_STAFF	[18]
