Defenc(s)e analysis frommy corner ofthe Internet.
Speed, altitude and angle of attack in photo?Other aircraft do that as well, at low level, slow and high alpha. Ie, in the landing pattern.
You mean, other stealth aircraft? Note, the F-22 can produce brief contrail events. But not like this. And, it isn't just the contrails you see within the visual spectrum.
My point is that the picture is not representative of an f-35 trying to be "low observable".
What micron band sensor? What would the range v sensitivity requirements be and what are the corresponding false alarm rates against representative clutter backgrounds?What bandwidth do sensors out there use and what would their performance be against these vortices?
I didn't know the F-35 was already practicing with smoke-winders for airshows!Whether or not a 'next-gen' super atmospheric or dual-polarization type sensor could pick up such disturbances at relevant distances, the wing-tip 'vortice' issue could be especially negative in a WVR engagement where visual directional heading and velocity etc are relevant.The above photo pictured however, at what, about 5-8 degrees AOA(?), might also be indicative of greater limiting handling issues which could come into play at higher AOA flight envelopes?
Hardly...Hornets have similar vorticies every day, but only when low and slow.They certainly have no issues with AoA handling.Further,http://www.freeimageslive.co.uk/files/images005/f-22_vapour_trails.jpg
These vortices relegate the JSF to the observable class of aircraft.These are tight but relatively large, powerful wing tip vortices that will persist well behind the aircraft, likely well beyond 1,000 metres.Less powerful vortices have been detected at 10+ nm behind cruising aircraft.By all accounts these vortices are optically visible to the Mk1 calibrated eyeball and IRST systems in both moist and dry air across a large portion of the flight envelope – up high, down low, fast and slow – thus providing a continuous pointer back to the aircraft generating them.Then there is the matter of such vortices being detectable via other remote sensing systems.The probability of dangerous, potentially damaging, and mission limiting WVEs (wake vortex encounters) is also considered to be high if not almost certain.

Which test report are you looking at Horde?
Once again, staggering intellectual input from the pack/sycophants
Perplexed,The foundation of academic argument are sources.Have you ever made an argument of your own?Flash
Reports that some people are scrambling to suppress through various classification devices and threats because these are reports hat they don't want others to see.Just a pity that the jets and their wing tip vortices didn't get the memo.Even if they had, it's pretty hard to hide this phenomona known as VOVS - visible and observable vortex shedding.However, there is no doubt that those who believe the JSF 'a total indifference to what is real' will try, using names like IVS...
Flew on the tankers at Pax River up to about 1.5 yrs ago. F-35 makes the visible vortices almost all the time. You could see them in the area. They always made them while tanking from the KC-130.
