Can you point me to the part of the NAO reports that deal with the actual threat?

JFZ90 30th Jun 2019 15:55

The belief that the NAO reports can be relied upon is touching but I’m sure many understand why they usually fail to provide a balanced view. Surprised this is not a more widely held view.

Roundel not on both wings
 
Out of curiosity, why is the UK roundel only on the port wing? The only other time I recall that happening was on camouflaged heavy aircraft (e.g. Beverley, Victor, C130 etc) in the 1960s/1970s. Never understood the reason for that either...

JFZ, perhaps if you could give us an illustration of what you see as a a "balanced view" it might help us understand your viewpoint?

Cost saving!!!! Every little helps in these troubled times!!! :ok:

Never thought of that. Obviously correct

I hinted at it in my email - e.g. is a balanced view being taken of the cost and difficulty of an LO solution, and how that difficulty could have been seen three times in three bespoke aircraft etc.

And to what extent is the LO worth it? Looking at open source info, if it’s a “metal marble”, then is it useful to have an aircraft costing £100m that is detected/tracked at a range of tens of Km if they other side are lucky, vs a £80m F18 which is seen & tracked and shot down by the same systems at 200+km. Of course its more complex but you rarely see articles recognising the benefits of LO.

Other questions are could it have been done quicker and cheaper through better mgt, or are the signs there that de-risking was comprehensive enough whilst never likely to capture & remove every dev problem in such a bold project, and broadly it does do what it should. It’s no F111B with flaws that would drive cancellation for instance. I suspect they possibly did overlap dev and prod too much, but who is to say what is right - wait too long and obsolescence is an even bigger challenge.

My request is simply based on the fact that a google pulls up loads of what I suspect are pretty ill informed castigations of F35, with stuff about EO tracking and stealth not working etc. It’s simplistic drivel quite often and obviously not so simple.

I read the latest GAO report and found it quite amusing - they sound quite like the NAO! :) Their recommendation to delay the latest development investment in batch 4 in case its takes longer than expected is a particular gem. When you look at the meat of their concern it can sound like they are not practitioners. You can almost see the eyebrows raising as the DoD wrote its response.....

I have no experience of the F35 programme so could be completely mistaken of course.

There is more to the F35 than it ‘simply’ being an LO fighter.

The sensors and other clever wiggly-amps are what really set it apart.

Now, I am not the person to discuss those capabilities on here but there must be something on google to highlight what I am talking about.

I’m sure thats the case Bob, I touched on the SA aspects too. I’ve heard the radar and ew suite are quite something.

I’d have thought there would be something balanced out there - and felt sure the contributors here would know if there was.

I’ve already parked the GAO - their focus is actually quite narrow it seems. Shame.

Single roundel on port upper wing surface, and single on starboard under surface is actually quite common to modern jets, especially NATO, and especially with modern gray low visibility schemes. Not just a F-35 thing, you will see some RAF Tornados and Typhoons in this scheme with only a port upper wing roundel- but not all depending on the date of the scheme, role, special commemorative schemes, etc. Port upper and starboard lower is a US standard and perhaps a NATO standard for tactical jets- results may vary- not all follow the practice.

Note the Israeli F-35's in the formation above have roundels on both wings. Non-NATO countries seem to have a mix single/both wing roundels.

Some of what I've been informed by careless whispers about the F-35B is pretty amazing. No, I will not explain further.

However its 6000kg fuel load isn't exactly generous.

But will the UK buy the F-35A rather than more F-35Bs? If so, will the tankers be modified or the F-35As? Either option will be rather pricey...

melmothtw 1st Jul 2019 19:49

You have to suspect that any F-35A buy will be the tipping point for modifying the Voyagers, and that the expense of this will be factored into the procurement. Of course, that would require some joined-up thinking.

Timelord 2nd Jul 2019 09:09

Or buy the C model. Already probe equipped, more internal fuel and may prove useful if we ever modify the QEs to conventional carriers.

ORAC 2nd Jul 2019 09:25

More fuel, but a bigger wing and more drag, ending up with a much longer transonic acceleration, lower thrust to weight ratio and no greater range than the F-35A. That’s before you add in that it won’t benefit from the proposed conformal tanks etc being looked at by LM for the F-35A.

Thats before you consider the total planned production run of the F-35C is about 320, assuming the USN doesn’t cut its order, as opposed to several thousand planned F-35As, meaning the cost of spares and support will be even more eye watering than the A or B.

Timelord 2nd Jul 2019 09:39

Complicated innit?

melmothtw 2nd Jul 2019 09:57

Is that confirmed? I haven't seen any official announcement that the CFTs are for the A only. On the same subject, do we know if the drop tanks are for all variants (LM seem to be of the opinion that the B is plumbed and wired for them, despite claims on here that this was all stripped out some time ago to save weight).

Thanks - a very reasoned response. I suspect they are focused on outcomes, especially financial ones... it might take a great deal of time to investigate the swamp of procurement decisions and trade offs ..........

Tricky. The F35C is the best looking variant - does that carry any weight? :)

Is it a totally crazy non-starter to put the probe into an F35A?

orca 2nd Jul 2019 18:10

Do the A and C really have the same Combat Radius?
