Which class has a length of 610 feet and is an amphibious assault ship?

• A. Zumwalt-class destroyer
• B. America-class LPD-33
• C. Freedom-class LCS-1
• D. Whidbey Island-class amphibious assault ship

Answer: (D)

Think about the ship type by both its size and its mission. A class about 610 feet long that is built to carry and deploy landing forces fits as an amphibious assault ship. The Whidbey Island-class fits this: they’re dock landing ships designed to transport Marines and landing craft and support amphibious operations, and they run around 609–610 feet in length. The other options don’t line up with both criteria: the Zumwalt-class is a stealth destroyer (about the same length, but its role is missiles and air defense, not landing troops); the America-class is much longer, over 800 feet, as a full-size amphibious assault ship; and the Freedom-class is a much smaller, faster littoral combat ship. So the class that matches both the length and the amphibious mission is the Whidbey Island-class.
