During the tests, the engine was operated at a maximum altitude of 45,000 feet, with the testbed achieving a maximum speed of Mach 0.90. According to Rolls-Royce, the test campaign achieved all of its objectives and gave the company confidence in the maturity of the program as it continues to work with Dassault on the 10X programme.
