In 2022 King Stallion military helicopter finishes testing

Aircraft designed for Marines expected to enter service in 2023

In 2022 will end the last tests scheduled for the military helicopter CH-53K King Stallion produced by the US Sikorsky, a subsidiary of the Lockheed Martin Group. It is an aircraft designed for the United States Marine Corps, which needs a heavy rotary-wing aircraft that is strong and reliable, capable of transporting equipment and vehicles from shipboard to shore.

The helicopter is expected to enter service in 2023, but first it must pass final technical tests that are expected to be completed, after several postponements, this year. The Marines already deployed the first two King Stallion prototypes on an official Search and Rescue (SAR) mission in the White Mountains in September 2021. 

A 2020 report, later confirmed in 2021 by the US Department of Defense's Office of Evaluation, found that the King Stallion was to be limited to 70 seconds in brownout conditions (lack of in-flight visibility due to dust or sand in the air) and testers noted degradation in engine performance, highlighted problems that could arise past 21 minutes of total activity in those conditions. The manufacturer Sikorsky has announced that it is aware of these problems and has resolved most of the issues highlighted in the report.
