From another translator:

Currently, we are preparing for the event Summer Event 2015: Limited Time Area "Counter Attack! Second SN Operation" which will be starting on 8/10 the coming week. This operation is a multi-stage "Large Scale Operation". ※「A Operation (甲作戦)」and 「B Operation(乙作戦)」, requires you to devote your fleet strength to each operation stage.
