USAF/US NAVY 6th Generation Fighter Programs - F/A-XX, F-X, NGAD, PCA, ASFS news

I do love cruising around F-35 threads all over the internet and hearing "we dont have the money!!" then in the next breath Its all about 6th generation, laser firing, super fighters. LOL Suddenly money is everywhere.

NGAD is a concept exploration program. It's not exactly burning through billions. The F/A-XX is intended to fill almost the same roles as the A-12 (when it was cancelled). Right now F/A-XX is just an RFI.
 
This is really unacceptable behaviour by several forum members. I will be handing out bans shortly. I've removed all the clearly offensive posts from the topic, I hope.

That is awesome. Not just the concept of the 3D printing, but the fact that this might be useful in creating an accurate 3-view drawing of the concept...

On an unrelated note, I find it a shame that such an interesting topic is being polluted with personal attacks.

Not to dampen your enthusiasm guys - on the contrary, but 3D printing ("additive manufacturing") has been around in the aerospace industry/academia for at least six-seven years. There are several types of printers that work with different materials. The one in the Boeing video uses powder and resins mixed together. Some of the latest ones (and more expensive too) use metals and lasers to create strong metal or ABS plastic parts suitable for use, unlike the powder ones that are for display only. It's not quite there yet, but there's talk of turbine blades made out of Titanium.

I believe there are cheap printers nowadays to be had for about $2,500.
See for example https://www.inventables.com/technologies/makerbot-replicator%E2%84%A2-3d-printer
The prices are coming down and the capabilities keep improving. It is not absurd to think that soon individuals will be able to afford a 3d printer the same way some have small lathes or vertical mills in their garage. The use of a 3D printer does require CAD/CAM software knowledge though.

I am speaking more to the "build it now!!!" crowd. I don't think its going to go beyond exploratory level either. The Navy will end up buying more F-35s. How do I know? Because they ended going with upgraded Hornets, and the Navy is risk averse.
 
I wouldn't say risk averse. The Navy has undertaken some pretty risky programs like F7U, F4D, A3J and A-12 with varying levels of success. Problem is they found themselves with a slashed post-cold war budget and they basically had to choose between F-18E/F or nothing at all. Had they gone with A/F-X it would probably have been canceled or run into the same problems the F-22 programme did with a vastly underwhelming production run as the result.

A/F-X started out trying to meet the A-12 requirements (as A-X), which were already pretty aggressive. Adding air to air to the A-12 didn't help matters. A/F-X expanded on the air to air requirements, which changed things significantly. Unfortunately F/A-XX is pretty much the same role(s) that A/F-X was to fill.

The Navy, however, is hedging it's bets with UCAV-N/UCLASS. If the program is successful it's possible that a production UCAV could take over the penetrating strike and ISR roles, leaving F/A-XX to focus more on air-to-air.

Let me amend to say the modern US Navy is very risk averse.

I'm aware that they've been around for a while, but that makes them no less amazing. My brother and I have considered purchasing one (which I would no doubt wish to use to create aircraft models of unbuilt projects).
 
Sorry, didn't want to give that impression ;)
I think it's a truly transformational capability and I'd like to get one for our office. Prices have come down drastically, depending on your application you might get one for a reasonable price.

Systems capable of producing aerospace rated parts are still quite expensive and still going through the process of being proven. That said though, I agree with you that this is potentially a transformational capability and one that has an exciting future.

Looking at how the navy sinks billions into high-risk projects like DDG-1000, LCS, Virginia, EM catapults for carriers, railguns, UCAS etc I cannot agree with you.

Suddenly spending money is a measure of risk? Is the Navy a business?
 
Surely spending money on projects that rely on the use of largely new and unproven technologies to provide superlative performance constitutes high risk? If the USN was as risk averse as you claim they would not be building DDG-1000, railguns or build the CVN-78 with EM cats instead of proven steam cats.

Heres an article about navy risk aversion:

http://www.usni.org/magazines/proceedings/2011-01/how-are-mighty-fallen

EM catapults have more to do with easing maintenance and reducing even further people at sea, so the Navy can continue using the ol' trident in the pentagon.
Wow the Navy found a whole different way of doing the exact same thing?? Gutsy!! steam catapults are hard on aircraft so its not a tough decision.

tell me how CVN-78 is drastically different from its predecssors. A smaller Island? wow! an automated systems to have fewer crew members once again. More Super Carriers? What a surprise. What about smaller cheaper to operate carriers? What about a steam catapult version of the America? What about changing your force structure to be faster, better? what about buying F-35Bs to augment smaller alternatives? What about buying certain land based fighters? (F-22s? even Marines have written ideas about buying F-22s and land basing them in lieu of F-35Bs. showing at least an idea of alternative strategies, concepts) Where are the Navy's deep thinkers? Where is the brain trust? Where is the hungry group of officers looking for enemy blood and finding new ways to get it?

DDG-1000?

On 31 July 2008, U.S. Navy acquisition officials told Congress that the service needed to purchase more Arleigh Burke-class destroyers, and no longer needs the next-generation DDG-1000 class,[19] Only the two approved destroyers would be built. The navy said the world threat picture had changed in such a way that it now makes more sense to build at least eight more Burkes, rather than DDG-1000s.[19] The navy concluded from fifteen classified intelligence reports that the DDG-1000s would be vulnerable to forms of missile attacks.[20] Many Congressional subcommittee members appeared incredulous that the navy could have conducted such a sweeping re-evaluation of the world threat picture in just a few weeks, after spending some 13 years and $10 billion on the surface ship program known as DD-21, then DD(X) and finally, DDG-1000. That figure does not include the money spent for the two hulls (DDG-1000 and DDG-1001).[19] Subsequently Chief of Naval Operations Gary Roughead has cited the need to provide area air defense and specific new threats such as ballistic missiles and the possession of anti-ship missiles by groups such as Hezbollah.[21] The mooted structural problems have not been discussed in public. Navy Secretary Donald Winter said on 4 September that "Making certain that we have — I’ll just say, a destroyer — in the ’09 budget is more important than whether that’s a DDG 1000 or a DDG 51

Theres that "damn the torpedos" we need it nowness I have seen from the USN!!

What had once been seen as the backbone of the navy's future surface fleet[28] with a planned production run of 32, the navy has since been replaced, destroyer production reverting to the Arleigh Burke class after ordering three Zumwalts

Easy navy!! don't change too fast!! slow down you sexy traditionalists. 3 ships? and then buying the same old suddenly means you are revolutionary? The Navy is top heavy, brought on by years of "zero defects," and not enough ships for officers to command, but no shortage of promotions of course. The navy has also been very wishy washy about what they choose are going to cut or not cut, showing indecisiveness at what is most important to them. Do we see how spending money in your R&D budget doesn't mean anything?

This is also the bunch that things that airplanes can't fly over water with a single engine.

Do you see the difference between developing a new weapon system/toy/gizmo and then reverting to the old as soon as things get tough or a hard decision must be made? That's called gutlessness. Can you remember the last time the navy made something or invented something and said something as bold as
"there is no plan B- We need this" ??

Uh, no. Having a plan B is called sound management.

Uh, no. Having a plan B is called sound management.

Managers don't win wars, leaders do. Leaders make the hard calls, that the navy no longer does.
 
Leaders don't do fallback plans? That explains why there's so few of them, then.

'No campaign plan survives first contact with the enemy' - Clausewitz
 
Peacetime is when you reflect and start planning for the next war. You develop new tactics and systems, you rely on a brain trust of thinkers to help develop that and steer toward a future vision. Its not easy to fight for new things and big ticket items in peacetime, but thats when you have to do it, because wartime could mean its too late.

The navy is not doing this. They are unable to make hard decisions now that can pay off later.

for example the Zumwalt was brought up. Awesome program, something new, different. Then the navy bought a whole... 3 of them. and then dozens of the old type of ship instead. See how they start to let go of the side of pool before grabbing back onto it, rather than trying to swim?

You are more than welcome to research and prove me wrong using what you find, or you can keep on attacking the messenger and dissecting my words into infinity. Either way it is what it is. I'm only telling you what I am seeing, and how a lot of other military folks (including people in the NAVY itself) are too. You need to look how much the other 3 services have matured and improved in the last 10 years while expanding capabilities and then take a look at the USN.

So unless there is drastic change in Navy Leadership, I feel its a safe bet that the Navy will order more F-35s in the future rather than gamble on a dominating laser firing super fighter. But thats just me.

The Navy is building more DDG-51 ships (specifically, flight III) because their needs changed. The Navy's Radar/Hull analysis program looked at how best to support the Navy's commitment to BMD, and the results favored flight III over changing the DDG-1000 to fulfill that role.

To get back on topic, this Flight Global article talks about the F/A-XX RFI:
http://www.flightglobal.com/news/articles/us-navy-issues-fa-xx-rfi-370806/

The important takeaways are:
- Persistent penetration of a modern air defense network
- Solution should compliment F-35 and UCLASS
- Both air superiority and strike roles
- Solution may be a single platform, or system of systems

As these requirements are based on A-12, and later A/F-X, the survivability requirements are much more agressive than those for the F-35. A/F-X was looking for about 200 aircraft, while if F/A-XX is to replace the Super Hornet it should be a larger production run.

"Future weapons will be complex" and expensive and still easily countered..again do the people making these slides have a bit a clue..

Saying a thing is "easily countered" doesn't necessarily make it so.

countered where 'it counts' to 'easily' is fine enough..

Like I said, talk is cheap.
and so are threat weapons not to be discussed here.. so it will said again, complex, expensive and countered where counts... waiting for your expensive talk.
 
"Future weapons will be complex" and expensive and still easily countered..

Heh. In the late 80s/early 90s, Dark Horse Comics came out with their spin on what a sequel to the film Aliens would look like. It was outstanding and gripping, but the thing that really grabbed me was the weapons developer who wanted to find the aliens' homeworld because the alien itself would soon be "passe" as a bioweapon and they needed to find some sort of creature that could beat it (both on the battlefield and in the marketplace), notwithstanding the fact that they couldn't even control what they had.


This reminds me of that mindset. There is casting about for ideas for the replacement just as the current model goes into service (fair enough), and then there is taking the leap directly to bemoaning the fact that the replacement will one day be obsolete before it's even conceived. The latter does not IMO lead down a realistic path. It's like wanting an F.155T design with Red Dean in 1937 because the Spitfire and the Browning MG might one day be outclassed, and expecting Whittle and either Camm or Mitchell to build it for you within a few months within the same cost limitations. Whatever the US builds in the next generation, there will be only one type of, it will be expensive, and it will have to be got right the first time.

I must say, Boeing certainly knows how to design ugly aircraft. :eek:
 
I actually prefer the Boeing design, aesthically speaking. I don't really like the inlets on the other design. I just don't see how the other design (LM?) inlets would work at high AOA.
 
I would say the same about the Boeing design. The airflow to top-mounted intakes would be very limited in high AOA.
 
Form should follow function, certainly. Beauty is in the eye of the beholder. The Boeing and Lockheed designs are beautiful, they're fighter aircraft. Nothing more useless than a handsome vehicle that doesn't perform.
 
Based on how closely drawings of future fighters from 1975, 1980 and 1985 resembled the ATF prototypes that emerged in 1990, I look at these renders and laugh.
