Boeing has announced it is to reveal the 777x on March 13 at its Everett plant in Washington
The 777-9 is powered by the GE9X and is due to enter service next year.
The announcement was made via Boeing’s twitter page.
The 777-9 is one of two variants and can seat 400 to 425 passengers in a standard configuration and offer a range of 7,600 nautical miles (14,075km).
The first 777X test airplane for static ground testing was completed in September 2018. Three additional flight test airplanes will be built after the first flight test.
Systems testing of the 777x started in June 2018 in a new 11,600 square foot laboratory, called “Airplane Zero” built by Boeing Test & Evaluation (BT&E).
The 777-9 is expected to enter service in 2020, with a smaller variant, the 777-8 following a few years later.
