The December incident with the F-35B, which got out of control and, as they say, nodded on the runway of the Fort Worth Naval Aviation Base, prompted officials to temporarily stop accepting new aircraft, as well as F135 engines, while the investigation continues.
During the investigation of the accident, officials identified a vibration problem known as harmonic resonance and allowed engine deliveries to resume on February 24. The Joint Strike Fighter company was ordered to make adjustments to mitigate the harmonic resonance problem, which, according to the office, will allow fighters on the ground to return to flight.
In an official statement, a representative of the F-35 Joint Program Office said that within the framework of the program, efforts were made to mitigate the problem of harmonic resonance on aircraft awaiting acceptance from Lockheed Martin, and after mitigation and safety flights, aircraft acceptance by the Pentagon resumed.

Until recently, the US Air Force was considering whether to develop a new adaptive engine for a fighter within the framework of a program called Adaptive Engine Transition Program. During a briefing with reporters on the service's budget for fiscal year 2024, US Secretary of the Air Force Frank Kendall said that the service decided not to use the new engine in its budget request for next year, but instead will seek funding for a plan to modernize the existing engine model.
