Here's why Navy and Marine Corps training jets are grounded

A safety stand-down has grounded the Navy's fleet of T-45C Goshawk training jets after one trainer experienced a low‑pressure compressor blade failure before takeoff on October 11. Officials said no prior Goshawk mishaps have been attributed to this engine‑blade fault, though an August incident remains under investigation. The stand-down was ordered on October 14 to allow for a swift, coordinated review with industry partners. T‑45s have trained Navy and Marine Corps fighter pilots since 1988, with the C variant entering service in 1997. Flight operations will stay paused until the fleet can safely return to air. While the issue is being resolved, the Navy emphasizes safety as the top priority and notes that the pause affects training schedules across squadrons worldwide. Officials did not provide a timeline for resuming flights, stating that operations will resume only when it is safe to do so. The grounding follows ongoing preventive maintenance and fault analysis across the service's tactical aircraft programs.
