Andrew Carlson and the crew of Zumwalt took the ship to Alaska, where they experienced some heavy seas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe took advantage of a storm up near Alaska that presented us with Sea State Six conditions,\u201d said Carlson, referring to sea\u2019s waves between 13 and 20 feet high. \u201cAll told I\u2019d rather be on that ship than any other ship I\u2019ve been on.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The motion of the ship is different from previous classes of ship, Carlson told Defense News, but all told said it handles heavy seas better than other ships he has served on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cYou definitely have to get used to the roll, which is very short compared to other ships,\u201d Carlson said. \u201cFor those of us who have been on cruisers, especially up top, you kind of lean over 15 degrees and you wonder if you are going to come back. We didn\u2019t experience any of that. As long as you get used to the finer oscillation, it really handles very well.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The next step for Carderock will be to take the data from the testing on Zumwalt back to its enormous wave pool in the Maryland D.C. suburb and replicate the conditions on their model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cEffectively, we will be re-running critical portions of the trial at model scale onsite at Carderock,\u201d said Stephen Minnich, who ran the testing on Zumwalt, according to the press release. \u201cThis will enable us to quantify the differences between our model-scale predictions and our full-scale observations.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"990\" height=\"382\" src=\"\/wp-content\/uploads\/2026\/08\/carderock.jpg.jpg\" alt=\"\" class=\"wp-image-84225\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/carderock.jpg.jpg 990w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/carderock.jpg.jpg?resize=300,116 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/carderock.jpg.jpg?resize=768,296 768w\" sizes=\"auto, (max-width: 990px) 100vw, 990px\" \/><figcaption class=\"wp-element-caption\">The wave pool at Carderock in Bethesda, Maryland.
