Sikorsky CH-53K King Stallion is a heavy American cargo transport helicopter developed by Sikorsky Aircraft in 2015.
This aircraft was developed by American aircraft manufacturers as a worthy replacement for helicopters of this model of previous generations. In particular, American engineers were able to qualitatively optimize the design of the Sikorsky CH-53K King Stallion helicopter, provide multi-purpose use of this aircraft, and, in essence, make the helicopter more operational in terms of performance.
The external design of the Sikorsky CH-53K King Stallion helicopter has practically not changed compared to previous versions, however, at the same time, it acquired some additional elements that do not technically affect the operation of this aircraft, but in fact, provide higher aerodynamic performance.
Like previous versions, the helicopter model Sikorsky CH-53K King Stallion is considered exclusively as a cargo transport aircraft, applicable mainly to the needs of the US Air Force. Depending on the objectives pursued, up to 55 people can be accommodated onboard the helicopter, or the amount of cargo is equivalent in terms of occupied space. Nevertheless, the carrying capacity of the Sikorsky CH-53K King Stallion helicopter has increased significantly, and as the American aircraft manufacturers themselves note, if necessary, the helicopter can carry up to 15,900 kilograms of payload on its board or an external hitch, including to the possibility of transportation by air of various kinds of large-sized objects, equipment, etc.
The armament present in the helicopter does not allow it to engage in open combat clashes, however, in the event of such a need, the helicopter can provide fire support from the air, and it is very effective to combat lightly armored enemy equipment, which is facilitated by the presence of three large-caliber 12.7 mm. machine guns.
The power plant of the Sikorsky CH-53K King Stallion helicopter has undergone several significant changes. Three General Electric GE38-1B turboshaft aircraft engines are used here, each of which is capable of developing a power of 7,500 hp, which is one of the reasons for the rather high carrying capacity of this aircraft. The flight speed of this aircraft has also increased significantly, and now the cruising indicator is 315 km \ h., While the maximum flight speed can reach 345 km \ h. As for the maximum flight range, the reverse changes occurred here – the maximum distance this model can fly was reduced to 865 kilometers, however, as before, if necessary, the helicopter can be additionally refueled during the flight.
