Design
Although dimensionally similar, the three engine CH-53E Super Stallion or Sikorsky S-80 is a much more powerful aircraft than the original Sikorsky S-65 twin engined CH-53A Sea Stallion. The CH-53E also added a larger main rotor system with a seventh blade.
The CH-53E can transport up to 55 troops or 30,000 lb (13,610 kg) of cargo and can carry external slung loads up to 36,000 lb (16,330 kg). The Super Stallion has a cruise speed of 173 mph (278 km/h) and a range of 621 miles (1,000 km). The helicopter is fitted with a forward extendable in-flight refueling probe and it can also hoist hose refuel from a surface ship while in hover mode. It can carry three machine guns: one at the starboard side crew door, one at the port window, just behind the copilot, and one at the tail ramp. The CH-53E also has chaff-flare dispensers.
The MH-53E features enlarged side mounted fuel sponsons and is rigged for towing its mine sweeping "sled" from high above the dangerous naval mines. The Sea Dragon is equipped with mine countermeasures systems, including twin machine guns. Its digital flight-control system includes features specifically designed to help towing mine sweeping gear.
Upgrades to the CH-53E have included the Helicopter Night Vision System (HNVS), improved .50 BMG (12.7 mm) GAU-21/A and M3P machine guns, and AAQ-29A forward looking infrared (FLIR) imager.
The CH-53E and the MH-53E are the largest helicopters in the Western world, while the CH-53K now being developed will be even larger. They are third in the world to the Russian Mil Mi-26 and Mil Mi-12, which can lift more than 22 tons (20 tonnes) and 44 tons (40 tonnes), respectively.

Famous quotes containing the word design:
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (16721719)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (16131680)
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
