The marines have finally received their first monster ch-53k king stallion helicopter – the drive electricity physics formulas

In its own annual review of the program’s activities during the 2017 fiscal year, the Pentagon’s Office of the Director of Operational Test and Evaluation raised main similar concerns, noting that at September 2017 Sikorsky had not yet even finalized the CH-53K design. In addition, at that time, the flight test plan was only 10 percent complete and continued to slip due to technical issues. Beyond that, the Marines do not even plan to submit the aircraft to initial operational test and evaluation until after the IOC date, similar to the controversial decision to put the F-35B into active service without putting it through that process to determine whether or not it is actually ready for combat.

"Pressure is increasing to meet a late December 2019 Initial Operational Capability (IOC), but current projections estimate that the planned 6-month IOT&E [Intiaial Operational Test and Evaluaition] will have started 1 month prior to this desired IOC," the Director of Operational Test and Evaluation’s report for the 2017 fiscal cycle noted. "Schedule compression has the potential to adversely affect training for the IOT&E aircrews and maintainers.

After the Berlin Air Show later in April 2018, which was the international debut for the King Stallion, the Marine Corps dismissed the concerns in the Bloomberg report, saying they were out of date, but did not specifically address any other reports. “You saw the CH-53K fly. Did it look like a helicopter that has a thousand problems with it?” U.S. Marine Corps Colonel Hank Vanderborght, the program manager for CH-53-series helicopters, asked reporters rhetorically.

The Marines are heavily invested in the CH-53K, having determined years ago that it was critical to replace the older E models. The King Stallion has the same physical footprint as the Super Stallion, but is significantly more capable and features a glass cockpit and fly-by-wire technology to further improve performance and reduce pilot workload. The three General Electric T408 turbines provide approximately 50 percent more power to drive an all-new transmission and a rotor assembly with improved, more efficient blades.

This allows the CH-53K to reach a maximum speed of around 230 miles per hour and have a maximum, gross takeoff weight of around 85,000 pounds. It can carry external loads up to 27,000 pounds across distances of more than 100 miles. The CH-53K has increased internal volume, as well, to better handle oversized cargo and small vehicles.

"It gets the Marine and naval force off our amphibious ships or wherever you are in a manner which cannot be accomplished by any other aircraft in DOD [the Department of Defense]," Lieutenant General Steven Rudder, the U.S. Marine Corps‘ Deputy Commandant of Aviation, told members of Congress in March 2018. "We are able to dual lift Humvees, full-up armored Humvees. So that capability allows maneuver on the battlefield."

The King Stallions can also lift the significantly larger Joint Light Tactical Vehicle (JLTV), which will eventually replace many of the older Humvees. "It’s the most advanced logistics support platform to warfighters," U.S. Marine Corps Captain Sarah Burns, a service spokesperson, boasted to Marine Corps Times earlier in May 2018.
