Low Observeability of the F-135 engine

to me it looks like the auto light meter on the camera is being overexposed. As the plane moves, it gets a better look up the pipe, goes overexposed, it then re-adjusts

Did you watch the video with the sound on? It's definitely NOT a light meter.

Super Hornet does the auto A/B night catapult dance at beginning of this video (the rest of video not that interesting). Note at the end of the cat stroke the left anti-collision light flash affects the film then the right one flashes as the aircraft lifts off. I'll post an edited version with slo mo of cat soonish. There are cat SusPEnD/BolTer/arrest bits also.

Okay, I'm convinced.

On page one of this thread a '3 stage afterburner' is mentioned whereas in the recent 'test pilot' lecture video the pilot says 'four stages' (when tanking at heavy weight high altitude behind the iron maiden). https://www.youtube.com/watch?v=faxuDFHJ3NY

FALSE, they will already be dead.

On a more serious note, is there much literature discussing the feasibility of using advanced microphones to perhaps detect stealth jets? I wonder how far these could range, and if they are at all practical.

Well how do you know what your listening to?
Just check out for a moment, this graphic of traffic just over Persian Gulf FOR JUST A SINGLE AIRLINE then mentally add in the other Airlines and then add non-stealth military traffic at various altitudes and then try to imagine your advanced microphones trying to sort out all the various sounds echoing around.

I get that you're trying to locate a stealth aircraft that may or may not be out there somewhere but it isn't clear how you could do that without the assistance of a completely empty location for hundreds of miles.

System of systems?

I'm not saying this will work, but...

If you can build a database of acoustics -- a library of acoustic signatures of all known aircraft, if you will -- then build a real-time "map" of all acoustic signatures... simply subtract all the locations of "known" aircraft from sources such as this, then subtract all "radar" contacts of "known" aircraft (e.g. radar contacts of known military jets)... and you are left with a sets of "unknowns" which may, or may not, be stealthy bogeys.

Not saying this would be easy, or in the end be successful, but isn't that how you would have to approach it?

I suppose the first question one would have to ask is if the acoustic sensors are able to distinguish multiple sources from different ranges / bearings. If not, then the problem just got a lot harder.

Has an integral spraybar/radar blocker, just like the F119 on the F-22.

Yup

some soft porn of F135-PW-600

I thought in years past the Soviet Union deployed a system called, "big ears" to detect incoming American bombers.

Or is that in the same league as "plasma stealth" ?

Dunno about ears, but plasma stealth tech exists and was used on Meteorit cruise missile, masking inlet.

Pentagon And Lockheed Martin Deliver 300th F-35 Aircraft
11 Jun 2018 LM PR

"...The first 300 F-35s include 197 F-35A conventional takeoff and landing (CTOL) variants, 75 F-35B short takeoff/vertical landing (STOVL) variants, and 28F-35C carrier variants (CV) and have been delivered to U.S. and international customers. More than 620 pilots and 5,600 maintainers have been trained, and the F-35 fleet has surpassed more than 140,000 cumulative flight hours...."

I thought that the video at 1:37 really showed the "radar blocker" / AB assembly well. Didn't want to comment in the Program Updates thread for this though.

There are a couple of threads with pics/videos of the **** end with radar blocker butt this one is from the vid mentioned.

See beginning OP of this thread then same viddy here etc..... & variable A/B goes POP!

You mean, a system invented by the British during WWI to detect incoming enemy (German) Zeppelins and aircraft?
