Which craft is Landing Craft Utility, used for land equipment and personnel in amphibious assaults with range > 400 nm and speed 10 knots?

• A. LCU
• B. UH-1N
• C. UH-1Y
• D. LCAC

Answer: (A)

The key idea is matching the asset to its typical amphibious landing role, considering both range and speed. Landing Craft Utility is designed to move land equipment and personnel from ship to shore during amphibious operations, and its performance profile fits a longer endurance with a modest speed. Its range exceeds 400 nautical miles and its speed sits around 10 knots, which is ideal for deliberate beach-settling and transporting heavier loads ashore.

LCAC, while fast and capable of delivering gear quickly, operates with a much shorter range and is optimized for rapid insertions rather than long-range shuttle operations. Helicopters like UH-1N and UH-1Y are air-mobile assets that lift troops and equipment through the air, not waterborne landing craft, and their profiles don’t match the specified beach-assault range and speed in this context.

So the choice that aligns with transporting land equipment and personnel over a substantial distance to the shore at about 10 knots is the Landing Craft Utility.
