The ship will be able to carry 14 helicopters; and could possibly carry up to 28 aircraft. However, only 7 ASW helicopters and 2 SAR helicopters are planned for the initial aircraft complement. For other operations, 400 troops and 50 3.5t trucks (or equivalent equipment) can also be carried. The flight deck has 5 helicopter landing spots that allow simultaneous landings or take-offs. The ship is equipped with 2 Phalanx CIWS and 2 SeaRAM for its defense. The destroyers of this class were initially intended to replace the two ships of the Shirane class, which were originally scheduled to begin decommissioning in FY2014.
