Blue Origin identifies BE-4 oxygen-valve origin in New Glenn ground anomaly

Blue Origin said recovered hardware and inspection traced May's New Glenn ground-test anomaly to the main oxygen valve of one BE-4 engine. The company plans a small valve modification and retrofit, with a return-to-flight goal later in 2026. The causal finding and schedule remain company-reported; the retrofit has not yet completed a return-to-flight demonstration.

Impact: the finding matters to New Glenn and the wider BE-4 ecosystem, including ULA's Vulcan. Investors and mission customers should watch corrective-action verification rather than the target date alone.
