The Spring 2015 Event ''Announcement! Operation 11'' [発令！第十一号作戦] is (tentatively) set to start on April 28th, 2015 and end on May 17th. The event will be based upon the planned Operation 11.

The (currently ongoing) Spring 2015 Event ''Order! Operation 11'' [発令！第十一号作戦] started on April 28th, 2015 and is projected to end on May 17th. The event will be based upon the planned Japanese Operation 11.

Like the [[Winter 2015 Event]], it will have selectable difficulties: Operation A (Hard), Operation B (Medium), and Operation C (Easy). This difficulty will be 'locked in' after the second map, and your choice of ships will also be frozen starting at the halfway point. There are numerous predictions that this will be a long event, and that the maps will be relatively difficult as compared to previous events, so teitoku are encouraged to prepare for the coming challenge. The event will last for 20 days.

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. The event will last for 20 days.

**Up to this point, route determination in KanColle was done by compass routing, which could be affected by various conditions such as fleet composition; however, through today's update, some maps will have "[[Active Branching]]", a routing system that allows the admiral to determine his/her fleet route by his/her own decision.
