Halloween is just around the corner, so it's time to look at a terrifying video. I call it "Day of the Looping J-31." Catchy, right?
(hat tip to Alert 5)
But let's be real. Like any horror movie, if you think about it too much, it stops being scary. The J-31 arrived in Zhuhai today, ostensibly in preparation for the airshow there, which starts on Nov. 11. The maneuver above, a half-Cuban 8, isn't particulalry arduous. It does not show off speed, maneuverability, and certainly not stealth--not that the Chinese military would be eager to put any of those things on display.
What I'm trying to say here is that the J-31 has been flying for a while now, but there remains no confirmable indication that, other than looking awesome, it or the larger J-20 can match or exceed the capabilities of other operational stealth aircraft. (Of which, to be fair, there are just two: the F-22 and F-35, with the retired F-117 flying around Nevada for who knows what reason).
What is "under the hood," specifically, remains questionable. Chinese engine technology is no great shakes, hindering not just military programs, but its commercial aviation industry. Less-obvious systems like low-probability-of-intercept radar, which allows a stealthy aircraft to track targets without its radar emissions giving away its position, are also tricky to develop. Without them or a robust airborne warning and control network, which China does not substantially have, a stealth aircraft's air-to-air capabilities are severely limited.
In the end, this video should be taken solely for what it is: neat footage of a neat-looking plane. It's not a milestone, and it's certainly not an indication of a closing technological gap... even with Jason Voorhees in the cockpit.
