recent US organization seems to just enjoy numerous debates without doing actions
If they're not going to build NGAD proper
Just get one Boeing to build the US version.A US GCAP/Tempest while I like that idea Forest Green it will never happen, there is too much at stake for the US aircraft companies.
Big news for NVidia too, since it's potentially a new market.On the topic of automation.
Radiation shielding for leading edge gpu.

This should help in using latest hardware in fighters.
Nvidia Orin was released in 2022. Future nodes are rumoured to be built with some radiation shielding because of electron transport and some issues as transistors shrink. Also easier to implement new functions on such powerful hardware. No need to bang the head with 28nm cpu.
Oh I know, but it beats the idea of this light fighter, which is basically just a copy and pasted F-35 re-badged as an NGAD.A US GCAP/Tempest while I like that idea Forest Green it will never happen, there is too much at stake for the US aircraft companies.
That's why I posted the article about GPUs. They can theoretically allow autonomous tech beyond anyone's wildest dreams. It should solve pilot retention problem and leave a ton of space on the jet. Full cost analysis which includes increased cost of research but should allow lower operation costs will need a full study. But I am confident that total autonomy is possible.Isn’t there a pilot retention issue and general shortage? Who’s going to fly these I’m assuming hundreds of light fighters? Another dumb dead end idea IMHO. Just build the darn NGAD.
Well, this is what happens when many different groups or parties of military leaders have varying and contradicting ideas on what they think is best for the Military as a whole. Military politics and the like.Generals don't know what they wants , one time a F-22 successor, one time F-35 , after they are in love of the F-15 after they are in love with CCA , and now they are in love with a light fighter unable to fight the great distance of the Pacific. And what new in inventory since 10 years ? nothing . It change every two years, there was the century series of M Ropper who was a good idea too so why don't continue that strategy ?
Sure David Axe, replacing the F-22 fleet with F-15EXs makes a lot of sense...
far more than Fury or QX-67.

Model 437 has flown. Interestingly I did not known that a lot of detail was released on the aircraft, far more than Fury or QX-67. It is powered by a PW 535 with 3400 lbs thrust and a 10,000 lb MTOW with 4000 of that being fuel. Cruise speed Mach 0.8 and range said to be ~3000 miles. 1000# of stores including a central bay for two AIM-120 sized weapons.
This craft seems larger than the Incr1 vehicles - 41 x 41 feet. But I think it points to what the USAF wants for the first couple increments: a pair of AAMs on a subsonic platform using an off the shelf engine.
Re the 437. That’s a
If you do the stupid person and multiply the cost per dry weight of the F-35 to a 10k pound estimate for 437 that’s a $30mm airframe just to lug two AMRAAMs / JATMs. These are pretty miserable maths to be dealing with tbh.
What are we going to do? In the absence of a) actual cost certainty it’s impossible to the confidence and support in congress to b) fund it. USAF is pushing F-22 as much as possible with new avionics, adaptable compute systems, new LO IRST pods & drop tanks, new coatings all while they try to salvage and upgrade as many early Raptor airframes as possible. Look at all the money invested in F-35 and how all that’s resulted in is severe constipation for TR3/Block 4. Might as well invest in EX if it’s capable of taking a AIM-174 class VLRAAM or lugging a couple HACMs. Those are pretty interesting high volume rooks to move around the TO that are difficult to ignore. I don’t know.
NGAD isn't dead, it has been paused to ensure the direction and set of requirements matches what the USAF thinks it needs going forward. That may result in a change of direction but that change isn't no NGAD, just a different form. The tech developed for NGAD will continue into whatever new form it takes.The more I think about it the more I believe the USAF was right to kill NGAD. Right now they’d be better off approaching a new fighter as they did with Raider.
?? One of the two Primes expected to be in the running for the manned NGAD is LM which built both USAF 5th gen fighters. How is that not continuity?The problem is they don’t have the prime continuity they did with NG to transmute B-2 into B-21, and NG has said NFW to NGAD.
The AF's leadership does not give you much confidence. Frank Kendall is an engineer and acts like one, throwing one idea out after another, before reversing course, pausing programs to reassess, then going off on another tangent. The AF needs leadership that knows what it's doing and sticks with a plan.Re the 437. That’s a

LockMart is kinda busy with unfucking F35 TR3/Block 4. They have absolutely not exactly covered themselves in Glory on this, more like covered themselves in sewage for being so far behind on deliveries.??

And Boing has proven themselves unable to engineer any new items.
Which leaves the one company that has delivered on time on budget, NG. Too bad NG said NFW are we bidding on NGAD...
Back in the eighties, the Northrop-Grumman/LTV combination effectively refused to submit a fixed-price bid on the ATA - which morphed into the A-12 fiasco. NG corporate memory at work?Which leaves the one company that has delivered on time on budget, NG. Too bad NG said NFW are we bidding on NGAD...
There is no indication that NGAD is going to be fixed price development or fixed price production (or both). With Boeing's leadership saying that they would not be bidding on FPC's, and knowing that it was one of the down selected OEM's it might suggest that the contract might not be as restricted in terms of fixed price components as the T-X, or the KC-46 that got the company in trouble over the last few years.Back in the eighties, the Northrop-Grumman/LTV combination effectively refused to submit a fixed-price bid on the ATA - which morphed into the A-12 fiasco.

F-15EX isn't a magic bullet, it is a marginal improvement over the F-15E fleet and it is pretty clear the USAF see it as that despite the marketing bluster from hacks like Axe. HACM is F-15E capable and will eventually make its way to the F-35 which is more than capable of lugging to HACMs externally should a cruise missile carrier role be required. AIM-174 I expect we won't see on the F-15EX or other USAF platforms, I can see it being a USN weapon only especially as the USAF seems all in on AIM-260 which likely matches better to the force structure and 5th gen platform intent.
The question is what role would an F-15EX play in a contested Taiwan straight conflict that is more important than the F-22? Sure it can launch long range AAMs and ASMs forward but who is going to target those and eventually you run out of targets and expensive weapons those F-15EXs can launch. SM-6 is not cheap nor will HACM be either and they likely will never have the stocks available comparted to other weapons. After you have expended those the F-15EX becomes a stooging 4.5 gen platform that cannot survive the dense IADS being developed and deployed by China without significant support likely better applied elsewhere.

I agree with you. there is no way LM, NG or B are willing to abandon their current manufacturing footprint that they have sunk billions into, to say nothing of their workforce (this is probably more of a comment about Boeing than anyone else). We need new primes. We need primes that actually have a software-first technology skill. We need primes that can and are willing to bet on risky new manufacturing approaches. We need primes that are willing to look at new propulsion and planform ideas. I dont know if LM, NG or B *can* ever change, but I suspect that if they can, they won't until they feel like they have no choice... they need to be put into an existential situation. The leaders of these primes are like people who were born on third and feel like they hit a stand-up triple: they survived the great contraction (twice) and have forgotten what a brutal business this can be without an oligopoly and the artificial peace post the Soviet period.The AF's leadership does not give you much confidence.

I've said this perviously, a CCA, costing $20-30 million, being attritable or semi-attritable and having a shelf life of ten years, is a terrible value. Much worse than paying $300 Million for NGAD. An F-35A will be able to carry 6 AMRAAM sized weapons in the near future. It also has a robust sensor suite and is much more versatile than a CCA in terms on weapons load. Seemingly for the price of an F-35A you get three CCAs. But mass has a quality of its own they say. But not if they get shot down like the Iranian and Houthi drones did once they were confronted with 4th and 5th Gen fighters from a first rate military with advanced ISR capabilities.
CCAs will be more capable than the suicide drones produced by Iran. But the AF needs to examine whether the US will be the losing end of a modern Mariana's Turkey Shoot over the Taiwan Strait.
A key questions regarding CCAs will be whether more innovative smaller companies like Anduril can change the cost paradigm with regard to combat aircraft. CSIS has a new report out about CCAs. The author, Greg Allen, thinks that may be CCA manufacturers might follow Space X and find efficiencies by taking a different approach to designing and manufacturing combat aircraft. We will see.

The argument wasn't on the competency, only on the continuity.
Agree neither LM or Boeing are shining themselves in glory right now but NG isn't exactly blameless either, they are running Sentinel after all...
Sentinel's problem isn't the missile, it's the contract written assuming that the 1960s infrastructure was still usable when any of the USAF missile crews could have told them it wasn't and needed total replacement. To the point that attempting to refurbish the old stuff was significantly more expensive than just starting over with new construction.The argument wasn't on the competency, only on the continuity.

F-15E is a 20 year old airframe with city miles bc of GWOT. Guess what? it will have to be replaced, along with the C models aging out.
Make that 30 years, at least. Most of the Strike Eagles have been built around 1990.
Btw. earlier this year, the first Strike Eagle reached the 15k flight hours milestone. Fleet average is about 10k hours.
Not yet, the airframe life was supposed to be 16k hours. They should start hitting 16k about 2028.Has the USAF started sending the oldest F-15Es to the Boneyard?
Assuming that those are the oldest birds, they'd be hitting 16k hours around then.
You replied to my response to an article by David Axe claiming to retire F-22s in favour of F-15EXs. Nothing you have said or I have stated contradicts the stupidity of Axe's claim.no one said EX is a magic bullet. far from it. the whole premise of my post is to look at the realistic options that get us say 100 airframes in the next five years. because the only option is to buy F-15EX, magically restart F/A-18E/F line (for what purpose I have no clue), Bigfoot into the Viper production line, or do the same with F-35. We cannot buy more F-22. Absent a new fighter, these are the options.
