Defense Department officials don’t think China’s stealthy J-20 combat aircraft will vie for supremacy of East Asian skies for at least another seven years, according to the Pentagon’s new report to Congress on Chinese military developments. “Although the appearance of this prototype underscores the level of [People’s Republic of China] investment in advanced defense systems, the Defense Department does not expect the J-20 to achieve an effective operational capability prior to 2018,” states the document, released Aug. 24. China unveiled the J-20 last December and began flying it in January. Although US defense officials have acknowledged that the J-20’s emergence came earlier than intelligence estimates had predicted, they maintain that it won’t be a cakewalk for the Chinese to field the aircraft. The report reinforces this, stating: “China faces several hurdles as it moves toward J-20 production, including the mastery of high-performance jet engine production.” But eventually, it notes, the J-20 will “give the PLA Air Force a platform capable of long-range, penetrating strikes into complex air defense environments.” (China report; caution, large file.)

Depot-level maintenance took longer than expected for nearly three-quarters of Air Force aircraft from fiscal 2019-2024, according to a new report, as unplanned repairs rise across the aging fleet. The report, from the Government Accountability Office, also found that the extent of the delays has been masked because officials often revise their target timelines after unplanned work occurs.
