Which ship sustains sea operations for seven days?

• A. LCU - Landing Craft Utility.
• B. LCAC - Landing Craft Air Cushion.
• C. T-AH - Hospital Ship.
• D. MPF Ship.

Answer: (A)

Endurance at sea is about how long a vessel can operate between resupply while carrying out its mission. The Landing Craft Utility is designed to sustain operations for about a week at sea when supporting amphibious tasks from a mother ship. It carries its own crew accommodations, fuel, and basic provisions to keep lifting and transferring equipment and personnel for the duration of a seven-day period, making it the best fit for this requirement. The other vessels have different primary roles and operating envelopes: landing craft air cushions are built for fast, short-range shuttle work with limited on-board endurance; hospital ships focus on medical capability and patient care rather than sustaining seven days of general sea operations; MPF ships are oriented toward prepositioned support and long-range logistics, with endurance framed by their specific deployment concepts rather than a seven-day operational window.
