2nd Map = COMBINED FLEET

今夏の「艦これ」夏イベ、その第一作戦海域は「通常艦隊」、続く第二作戦海域では「連合艦隊」編成での出撃が予定されています. 空母機動部隊編成の「連合艦隊」では、第一艦隊に精強な航空母艦及び同直掩戦力、第二艦隊に水雷戦隊を中核とした随伴護衛艦隊が必要となります.

The Summer Event this year will have its first map for normal fleet, and second map for combined fleet. A Carrier Task Force as a combined fleet will require elite carriers and its direct screening force as the first fleet, and a torpeto squadron-based escort fleet as the second.

I hope it does give carrier fleet its required advantage this time, last time it wasn't enough and ppl just go for surface fleet.
