The MH-53E Sea Dragon has what length and rotor arc?

• A. 99 ft long/79 ft rotor arc
• B. 105 ft long/75 ft rotor arc
• C. 90 ft long/72 ft rotor arc
• D. 100 ft long/80 ft rotor arc

Answer: (A)

Understanding the aircraft’s physical footprint is essential for deck clearance and hangar space planning. The MH-53E Sea Dragon measures about 99 feet in length and has a main-rotor arc (diameter) of about 79 feet. The length tells you how far the aircraft extends fore‑aft on the deck, while the rotor arc indicates the space the turning rotor requires, which drives clearance during flight operations and storage. Therefore, 99 feet long with a 79‑foot rotor arc matches the MH-53E’s documented dimensions. The other numbers would place the aircraft’s footprint outside its real size and would not provide the correct deck or hangar clearance references.
