What is the beam of a US Navy America-class amphibious assault ship (LPD-33)?

• A. 90 ft (27 m)
• B. 106 ft (32 m)
• C. 75 ft (23 m)
• D. 120 ft (37 m)

Answer: (B)

Beam is the ship’s maximum width at its widest point. For the America-class amphibious ships, that broad width is essential to support a large flight deck, a sizable hangar, and a well deck, while still maintaining stability in heavy seas and staying within harbor and channel limits. The measured beam for this class is about 106 feet (32 meters), which matches the design requirements for carrying aircraft, amphibious vehicles, and the associated weight distribution. The other figures don’t align with the ship’s hull proportions and operational envelope: 90 feet would be too narrow for the intended mission footprint, 75 feet is even tighter, and 120 feet would be unusually wide for standard port access and stability considerations.
