F-35 Cancelled, then what ?
Ecce Homo! Loquitur...
It is of course possible the additional unexpected loads are generated by the turbulence of flying around with the bomb bay open half the time......

" • The following details discoveries in F-35B flight sciences testing:
- Testing to characterize the thermal environment of the weapons bays demonstrated that temperatures become excessive during ground operations in high ambient temperature conditions. As a result, during ground operations, fleet pilots are restricted from keeping the weapons bay doors closed for more than 10 cumulative minutes prior to take-off when internal stores are loaded and the outside air temperature is above 90 degrees Fahrenheit. Time with the weapons bay doors closed in flight is currently not restricted."

"during ground operations, fleet pilots are restricted from keeping the weapons bay doors closed for more than 10 cumulative minutes prior to take-off when internal stores are loaded and the outside air temperature is above 90 degrees Fahrenheit. In flight, the 10-minute restriction also applies when flying at airspeeds equal to or greater than 500 knots at altitudes below 5,000 feet; 550 knots at altitudes between 5,000 and 15,000 feet; and 600 knots at altitudes between 15,000 and 25,000 feet. ......

If you are stating definitively that the F-35B does not have the same restrictions, my apologies. Though I do find it surprising, as I would have thought the reduced capacity would make heat dispersal even more of an issue, especially when taking IR signature into account.
Trump adds his five cents.

I have asked Boeing to price-out a comparable F-18 Super Hornet!
Proof, if it were even needed, that 'the Donald', hasn't got a clue...

I'd like to see what a "comparable" F-18 super hornet looks like ... in terms of how one could compare a 20 year old (but proven) fighter to something quite a bit different.
Are they both comparable by both being fruits of the poison tree of Congressional mandates on "one size fits all" designs?

Just wondering
With all the long range goodies on our ' fighters ' available since the 60's, I wonder if the ROE re requiring a visual contact before firing is still standard in an air to air situation ??
Other than escaping an incomeing miussile ( very important ) why the old meme re ' dogfighting superiority ' is still being pushed ?
for example

Considering the Donalds latest statement on "nukes", that trillion dollar in life service quotation for F35 would sure come in handy to help pay for the required modernisation and upgrades ...

Sorry for maybe disappointing you, but nobody here is scared of (or even concerned with) this ugly and overpriced plane. An easy target for modern (to say nothing of the future) anti-aircraft systems.

Rewatching some amazing footage of Bs on USS America
Video: Watch As F-35B Nails Vertical Landings Aboard USS America | Defense content from Aviation Week
I was struck again by how fragile that big door over the liftfan looks.
What happens if that door jams shut during seaborne ops? Presumably it would mean the loss of the airframe and hence, I can only hope, a Martin Baker letdown for the driver.
Or is there a jettison thingy for that door?
As ever, I don’t think this has been covered before in the thread - but if it has, I apologise….

Either the door or its support structure will give problems at some stage LOL
The trash can lid on the B does indeed "look" fragile. I was watching B's in the pattern at Patuxent River at 100+ knots and it does look like the whole thing should rip off, but obviously much more robust than it appears, and with so much air being sucked through the fan, the loads are not directly on the door.
I was wondering whom will be first to paint something on the inside of the lid- like the eyes on the cranked up F-8 Crusader wing. Would look great, but I'm sure the designers would cringe with the thought of paint chips going through the fan...

I presume ripping off would not be as catastrophic as being stuck shut, which would prevent vertical landing (embarrassing when you're at sea).

Longer_ron,
Ref Lift Fan Inlet Door redesign, they went through between 2007-2010.
