^I don't think the JSF will be cut, as it is so far down the track (although its not impossible that could happen). I think the program will likely change though, the number of aircraft purchased may reduce (and yes, I know that means cost per unit increases, which will primarily hurt international partners), and the B model may be eliminated (IMO a smart move if this happens).

We will know soon if I am right or wrong on this.

.
On price alone, the international partners dont give a dam what the final number of f-35's are built for the usa or how much over-run there is in testing, it has no effect on their price.
What will affect their price somewhat is how many are built each year that they are buying in.

I know what DC is.... A-10's, GR4's Harriers, FA-18's, F-16's F-15E's etc have all done Danger close before.. All of these fighters also have the ability to do it outside of visual range. All of them have saved significant amounts of bacon at times, and all bring something different to the fight.
Its about reinforcing that CAS is a capability - not platform centric

The events you are describing don't sound like they are typical, suffice to say that to make a blanket statement that a B52 is a better CAS platform (as in your opening line) is bogus. To say that they are better in SOME occasional scenario's is a far more accurate statement. Can you describe why an A-10 couldnt reach the contact area? or why a flight or four ship of F-15E's couldn't prosecute the same...

no, you're misunderstanding my point - its not that CAS is better done by a B52 or B1, its the fact that in a number of situations in Afghanistan single seaters or the like were unable to be used due to geographics, logistics etc.... eg they cannot loiter at range, they cannot carry the same load, they cannot redirect conveniently to another fight - and thats been a known problem.. eg ISAF have been unable to call in sustained single seaters due to distance issues and persistence issues, that has meant that the first fallback is to call in support forces in trucks (hercs etc....)

As I acknowledged, the load out and the playtime of a B52 far outweighs the ability of a F-16 or Harrier to deliver the same... But as an example how long does it take to turn a B52 around at 30kft if they abort the pass but you have a tight attack heading restriction..... 10 minutes? Try 2 minutes in a strike eagle or 1 minute if his wingy is doing a good job.
except the smaller assets don't have loiter advantages, there have been basing issues, carrier air has also not been able to assist due to range issues etc....
there's no shortage of examples in the last 5 years where heavy air has done better CAS than smaller air. Again, CAS is about capability and opportunity and the newer weapons actually favour the heavies over the fighters due to logistic and geographic constraints.

my point in all the above is those who dismiss the JSF to do CAS when we already know pet rock theories have been broken in the last 10 years and that the requirement has been addressed by assets that nobody would have thought possible 10 years ago

can the JSF do CAS - yes
can the A-10 do CAS - yes
can Blackhawks do CAS - yes
can B52's, B1's and B2's do CAS - yes.

its a capability issue, it hasn't been a platform centric issue for years, its been an available capability outside of the pet theories since GW2

With hindsight, it is not quite so clear that the Lockheed design was superior. Yes, it won, largely because of the superior performance for STOVL due to the lift fan. But, that fan set up has turned into an extremely expensive problem that has dogged the program, and lead to many of the cost over-runs. The complexity of getting these systems working, from a mechanical and software perspective, IMO wasn't fully understood.

Without the STOVL requirement, I think the contest would have been closer, and may even have favored the Boeing. This may have been the smarter move, the F22 could have remained in production as the premier fighter, without then the need to make the JSF as advanced as it now needs to be, to also carry out roles that perhaps the F22 could have covered / been expanded into.

A more interesting question, is whether or not it was every really that smart to think that a stealth aircraft could cost effectively carry out all roles. Yes, stealth is a huge advantage early in the war zone, but once air dominance is achieved with the F22's and cruise missiles for example, maybe a simpler platform to just deliver bombs like the F16 would have been a smarter option for the bulk of the forces fighters?

The whole concept of a JSF that covers multiple roles was interesting, but maybe a bridge too far. The superhornet was an excellent example of this working for the Navy, but I'm not so sure sticking VTOL in, along with stealth was really that doable. For example, there was even nonesense suggesting the JSF would replace the A-10, which suggests how out of reality / wrapped up in a concept fad, the planners had become. Clearly it can't cost effectively be both a high altitude precision fighter bomber and a low altitude ground support aircraft.
A commendable and very cerebral post.
The STOVL will over time however provide an unmatched capability. I think this will be demonstrated over the next 15 years or so.

In relation to the unexpected CAS role of aircraft nobody initially suspected - the same will apply to the F35. Necessity is the mother of invention.

I think so.. :)

I wasn't arguing that heavies were superior at CAS, just that the capability was no longer platform centric anymore

in respective scenarios, any given platform will demonstrate superiority, but if they're wired up and into the operating picture, then they enable those assets way beyond what they could do on a single task construct.

For all the naysayers on JSF I struggle to see what they don't comprehend about the system warfare element and how and what this plane brings to the battle/tactical picture as a systems enabler in its own right is quite significant.

the changes to the COP picture alone are huge....

If these figures are correct by Tom Burbage $65 million per flyaway cost not the whole of life cost why would you by Super Hornet, unless the program falls over. It would be more interesting to compare Super Hornet costs to an F35C which would be under more scrutiny for the US/UK and I think Italy, Spain would exit the fixed wing carrier ops if this were to be the case, I wonder if the tooling for AV-8 is being stored somewhere.

ADM: JSF better value than Super Hornet?

Because people like the Bill Sweetman and JWCook's of the world make poorly thought through and flippant "you can just bolt that stuff onto any jet but then you'll have the kit AND the airframe performance" type comments which are just rubbish, but they're easily digestible for the general populace and hence believed...

I don't think many people are disputing the F35 will be an excellent aircraft, the electronics will clearly be the best on the battlefield (although of course, the F22's could have been upgraded instead). Some of the issues are:

- Does the military really need as many F35's as originally planned? If not (i.e. if the F35 program is cut back like the F22 program was due to the budget crises, e.g. http://www.dailytech.com/Covering+C...May+Mean+Fewer+Jets+in+LRIP5/article22392.htm), did it really make sense to develop the F35 at huge expense rather than continue to upgrade the F22 and existing aircraft? With hindsight, it probably didn't.
- Does it make sense to have only one future supplier for fighters? Has this resulted in Lochkeed being lazy / fat / milking their development?
- Could simpler existing aircraft (or a new designed aircraft without stealth) perform many of the roles the F35 will be used for (like we see in Libya right now), at a cheaper maintenance cost?
- Is the STOVL variant really that important versus having the marines supported from full aircraft carriers / airfields? Given the extreme cost/complexity it is clearly a waste of resources that could have been spent developing the other variants quicker / more cost effectively. I think its highly likely the F35b variant will be dropped despite the political influence of the Marines, if the RN can live with out it, the Marines can as well.
- Does the US Navy really want the C variant, or would they rather have longer range, dual engine, Superhornets? Boeing clearly wants to have a crack at these contracts with its next gen Superhornet: http://www.boeing.com/farnborough2010/presentation/fas_gss.pdf

I guess I disagree here straight away. The F-22 is an architectural orphan, it was never built along a COTS distributed architecture construct, and the Block 1's are worse. The cost to bring them up to a JSF distributed/COTS architecture for number of frames would have been not just once across the fleet, but a minimum of twice across the Block releases. Integration is a killer. A few of us in here have direct experience of the pain that integration brings to weapons systems, let alone platforms

- Does the military really need as many F35's as originally planned? If not (i.e. if the F35 program is cut back like the F22 program was due to the budget crises, e.g. DailyTech - Covering Cost Overruns on Earlier F-35 Purchases May Mean Fewer Jets in LRIP5), did it really make sense to develop the F35 at huge expense rather than continue to upgrade the F22 and existing aircraft? With hindsight, it probably didn't.
The F-22 was also not seen as a volume priority once the threat visibly changed - the USN went through similar analysis with ASW (in fact everyone delaminated their ASW capability once the Soviets collapsed) The air superiority element required for continental europe no longer existed - the advantages of force compression provided with european/NATO co-basing also became less of an nissue and is fundamentally irrelevant around containing china - the force structure and posture to deal with china is different - its not an air war construct, its a maritime constraint. If anything the US needed more subs, and if you look at the changes in the last few years, the Virginia build program has had more diligent attention paid to it

- Does it make sense to have only one future supplier for fighters? Has this resulted in Lochkeed being lazy / fat / milking their development?
I've never agreed with single points of failure, credentialed engineers would also have the same view.. :) If anything at a minimum it serves to keep the vendors honest, there are just as many people involved militarily anjd politically who are unhappy with Boeing dominance as they are with Lockmart dominance...

- Could simpler existing aircraft (or a new designed aircraft without stealth) perform many of the roles the F35 will be used for (like we see in Libya right now), at a cheaper maintenance cost?
the emergent electronic and systems threats are far more complex though, as soon as you retro fit your assets you're remove inherent capability, when you build an asset your bulding in effect 45 years out. ie 10-15 years before IOC and at least 30 years on sustainment. You can't seriously build latent generation warfighting capabilities and expect it to be competitive in 10-20 years time. the threat and technology has advanced and you're left with sub-par capability. It makes no sense to build at parity technology levels

- Is the STOVL variant really that important versus having the marines supported from full aircraft carriers / airfields? Given the extreme cost/complexity it is clearly a waste of resources that could have been spent developing the other variants quicker / more cost effectively. I think its highly likely the F35b variant will be dropped despite the political influence of the Marines, if the RN can live with out it, the Marines can as well.
when you build a platform part of the process and validation is to build against vignettes and scenarios which test the requirement, in the long run, one would need to see what the USMC had in their vignettes - but you also need to recognise that the USMC have independant capability - and that they also in effect run their own carrier groups albeit ARG/ESG's. That means that the USN in effect has 20+ carrier task forces to field, thats significant redundancy of force and effect

- Does the US Navy really want the C variant, or would they rather have longer range, dual engine, Superhornets? Boeing clearly wants to have a crack at these contracts with its next gen Superhornet: http://www.boeing.com/farnborough2010/presentation/fas_gss.pdf
Again, the frame is limited and was never designed around a distributed architecture and the flexibility that some COTS capability brings, as much as I support mixed fleets (for a variety of reasons) the sustainment and logistics costs rise dramatically - in the current economic climate, mixing the platforms would cost more. The $3bn per year that it costs to support a carrier group would go through the roof if sustaining a mixed air fleet, and the mission flexiblity would take some severe hits as instead of weapons space you're now carrying mixed fleet spares for 2 aircraft types. Fuel and weapons takes a hit

It all depends on how you define cost. The flyaway cost may be $65 million, but the actual cost including all the development, is now closer to $155 million per aircraft:

In 2001 the Pentagon estimated that it would cost $177.1 billion, or $62 million per aircraft, to develop the F-35 and build 2,866 planes. Assuming some inflation and other cost increases, the price tag was projected to rise to $226.5 billion, or $79 million per aircraft.

Those figures have increased almost yearly. Pentagon number crunchers now estimate the development, production and all other costs of acquiring 2,457 F-35s (about 400 fewer than originally planned) could total $382.4 billion, or $155.6 million per aircraft.
Rising F-35 costs not too shocking

Current spending is simply unsustainable, especially when you consider the Baby Boomer social security ticking timebomb:

According to Kotlikoff, one of the biggest fiscal problems Congress should focus on is America’s obligation to make Social Security payments to future generations of the elderly.

“We’ve got 78 million baby boomers who are poised to collect, in about 15 to 20 years, about $40,000 per person. Multiply 78 million by $40,000 — you’re talking about more than $3 trillion a year just to give to a portion of the population,” he says. “That’s an enormous bill that’s overhanging our heads, and Congress isn’t focused on it.”

“We’ve consistently done too little too late, looked too short-term, said the future would take care of itself, we’ll deal with that tomorrow,” he says. “Well, guess what? You can’t keep putting off these problems.”

To eliminate the fiscal gap, Kotlikoff says, the U.S. would have to have tax increases and spending reductions far beyond what’s being negotiated right now in Washington.

“What you have to do is either immediately and permanently raise taxes by about two-thirds, or immediately and permanently cut every dollar of spending by 40 percent forever. The [Congressional Budget Office's] numbers say we have an absolutely enormous problem facing us.”
http://real-agenda.com/2011/08/11/u-s-national-debt-at-214-trillion-not-14-trillion/

Realistically, the US is not going to acquire even 2,457 aircraft now. Despite the goals of defense officials, there is no way in hell that the F35 program is not going to be impacted by the budget crises and the cutbacks that will come to the defense budget. See for example this article which explains why significant cuts would still easily retain US military supremacy:

Imagine the savings that could be had over a 10-year period: roughly $3 to 4 trillion (not adjusting for inflation). Perhaps this is a simplistic view of the mathematics of budgeting, but it seems $3 to $4 trillion over a decade is a rather good amount of savings. And what’s more, it would allow for a working and affordable healthcare system.

Republicans—the anti-tax party—should be front and center in the call for a 30-40% cut in defense spending, with the Tea Party lining up right behind them. For them, however, it is much better to cut funding for social programs.

As I noted in my article “A Modest Proposal to Republicans: How to Trim the Budget,” if the U.S. Department of Defense were hit with such cuts, our country would “still account for 20% of military spending worldwide, with China, our nearest competitor, at around $100 billion.” We’d still be outspending China by a ratio of approximately 4 to 1.
U.S. Defense Budget Cuts Could Save Trillions, And the U.S. Economy | Death and Taxes

It wouldn't surprise me for example, to see the number of aircraft, drop to say, 1,500, which will push the total cost per plane (but not overall) up even higher.

On the other hand, the research and development to get the plane operational will eventually become a sunk cost once all the initial development is out of the way, at which point, the flyaway cost does become more relevant. In other words, the horse has already bolted (except to the extent programs like F35b can be cut), which makes a better case for the F35. However, you also need to consider though, not just flyaway, but also ongoing maintenance, which has also been a disappointment of the program (exceeding existing aircraft, when it was originally supposed to be comparable or even cheaper).

At the end of the day, a number of F35 aircraft will likely be acquired, but probably nowhere near as many as defense officials want (yet still easily enough to retain supremacy, per that 4 to 1 advantage above even if the total defense budget is cut 30% or so). Its bad news for the aerospace industry though, because there won't be another program on the scale of the F35 anytime soon, by messing this up / milking it so much, Lockheed has hurt everyone in the industry, and also hurt military who will end up with fewer planes than they would have, had this program not gone off the rails, or simply hadn't happened.

Well that’s the $64000 question how did he define that amount, it’s a fly away cost no support no munitions integration costs etc. Defence has to determine the actual operating cost between F35A and Super Hornet, just the same as the USN/RN have to determine cost between F35C and super hornet for their carrier fleet now and into the future, there must be a reasoning for a dual fleet of Super Hornets and F35C for the USN and not replace all the hornets with F35.

It is the same with Tiger ARH we had our fly away cost, but defence integrated other munitions at a further cost to the airframe, add those cost to the program and it might have been more feasible to have bought AH-64 Apache in numbers with a quicker in service date than Euro Tiger.

No it isn't. It is very well defined as to what this cost it is: flyaway cost. Which includes the cost of integration of munitions. It doesn't include the cost of weapons expended and fuel burnt but what aircraft buy does?

Of course but it isn't rocket science. The big variable issue in sustainment cost is maintenance with lots of new projects promising all sorts of cuts to costs that they don't deliver on. Which usually isn't as bad as it sounds as the costs of maintenance for old aircraft tends to skyrocket, as in the case of the F-111. Aus DoD, the HM DoD and so on do this all the time and they keep coming back to F-35. I wonder why? Its either the Clown Club's grand conspiracy or the F-35 makes good sense.

The reason the US Navy is keeping a mixed fleet of F-35Cs and Super Hornets is they don't have the money in the next 30 years to buy 1,000 F-35Cs. However when the life of the Super Hornet expires in 2030-40 they will consider additional F-35Cs if they don't have the money for a new build alternative or don't trust a UCAV for 50% of their tacair fleet.

It is the same with Tiger ARH we had our fly away cost, but defence integrated other munitions at a further cost to the airframe, add those cost to the program and it might have been more feasible to have bought AH-64 Apache in numbers with a quicker in service date than Euro Tiger.
This is totally wrong. The cost benefit of the Tiger vs the Apache was in claimed maintenance costs. Eurocopter claimed the Tiger would cost half as much to maintain. This has later been proven to be false and the Army is stuck with ISD delays with no long term payoff.

What a suprise that the F-35 thread has another injection of factual error and subsequently wrong analysis.

Don’t get me wrong I am a supporter of the JSF in the RAAF, only I am bit weary of putting all our eggs in the one basket, if through life cost are better for the RAAF I can understand having a single type in the fleet considering our small ACG compared to a larger Airforce.

I am also led to believe that the flyaway cost to Australia is lower due to being a level three partner and we have been quarantined from paying the R&D cost for the other two models.

So you are saying defence knew how much the integration cost and what time frame would be for a different EO set up and factored that in from the start and give up the royalties from others to do the same.

None of this is true. As a level III partner Australia paid 1% of the programmed R&D cost (~$100m) with no obligation to pay more. There is no quarantining from the F-35B and F-35C, we could order these models without paying more to R&D if we wanted. Because of this partnership will also get any FMS purchases of F-35 program products and services wihtout the additional management loading cost. The US does not charge R&D for all FMS deal, they can't as its the law. You only have to pay for R&D if you contract a US company outside of a US DoD program. But in some cases, like 737 AEW&C, they will wear the R&D cost themselves as they want to profit from selling on the product.

So you are saying defence knew how much the integration cost and what time frame would be for a different EO set up and factored that in from the start and give up the royalties from others to do the same.
The Tiger ARH has exactly the same EO set up as other Tiger HAD helicopters in French Army service. The cost of integrating the Hellfire weapon was a very small element of the program cost and schedule. The delay in the Tiger has been because the entire Tiger program (French and German) has been delayed.

If you have your fact base so wrong you really shouldn't be making calls about whys and hows.

It does have some integration and certification issues outside of the French/German requirements though - if it was just a "batteries not included" issue then people would be happier...

The cost estimates you are jumping on are far from set in stone. I suggest you have a read of the following balanced article:

How Much Is that F-35 in the Window? | The Moderate Voice

Total estimated acquisition cost, PAUC , APUC, lifetime operating and sustainment costs, constant FY2002 dollars, then-year dollars, constant FY2010 dollars, are just a few of the factors and variables involved in coming up with a credible and realistic “price tag” for the F-35.

Now, add to this mix the number of F-35 variants and final configurations, guesses at and adjustments for future inflation, per-unit cost dependency on total aircraft produced — including assumptions for international buys — numerous and continuing changes in government requirements and scope of work, differences, changes and vagaries in cost accounting methodologies and rules, etc., and one begins to get the idea.

Additional factors and considerations are major cost/budget implications of political issues such as the on-again, off-again, on-again alternate engine debate — an engine now to be developed by General Electric and Rolls Royce for the next two years with their own funds, hoping for a” change of heart” by Congress.

Such issues, vagaries and variables contribute to the complexity of putting a credible and reliable price tag on the F-35 and leave plenty of room for error, misunderstanding and confusion.

...

Of course I cannot tell you how much an F-35 will eventually cost the U.S. taxpayer, but then I doubt it whether Lockheed Martin, the JSF Program Office, the Pentagon, the House and Senate Armed Services Committees — or anyone — will be able to.
Even for international partners where there are contracts, like in Canada, there has been huge debate as to what the price will be. The reality is we simply don't know yet what the flyaway cost will actually be. We also don't know what the total cost will be, or the total cost per unit. We also don't know how many units will be built, and what impact that will have on flyaway (it will impact even flyaway as more units will generate economies of scale) and total cost:

Moody's warns that big programs, particularly those behind schedule or over budget are vulnerable to quantity reductions, deferrals or in some cases, cancellation. The report highlights programs such as Lockheed Martin's (Baa1, stable) $385 billion F-35 Joint Strike Fighter project, the Textron (Baa3, stable) partnership with Boeing (A2, negative) on the $55 billion V-22 Osprey tilt-rotor aircraft program, and Lockheed Martin's split (with unrated Austal) $34 billion Littoral Combat Ship program as being exposed to potential cut..
Read more: Moody’s Sees Half-a-Trillion or More in US Defense Budget Cuts | Defense & Security News at DefenseTalk

All we do know, is that to date, the program is massively over budget, which along with a struggling economy and a mandated cut to defense if the budget committee can't come up with alternatives, is far from a good sign. If the program weren't over budget, if Lockheed and the Pentagon had kept the program under control (perhaps pulling the plug on expensive elements, e.g. the F35b), then it wouldn't be one of the ones facing the possibility of the chopping block.

A few questions..

I'm sorry if this has already been mentioned on this thread, but I was wondering why the F-35 has a shorter range than the F-15, F-16 and F/A-18 Super Hornet that it replaces?

As far as I know, its lone engine produces about the same thrust as both the others' twin engines, it weighs about the same and can carry more fuel.. what gives?

Once again, sorry if this was already brought up or if any of my info is incomplete.

The F-35 doesn't have shorter range than the F-15, F-16 and F/A-18. The F-35 is designed to achieve a mixed strike, air to air mission with a radius of 600 NM. It is a bit below this (<10%) at current predictions and this radius includes 4,000 lbs of bombs and 500 lbs of ATA missiles and no external tanks for a full LO profile.

The combat radius of the F-16 and F/A-18 with similar weapons load and all the external tanks they can carry is around 300-350 NM. Without the FAST external fuel packs the combat radius of an F-15 with similar weapons load is about the same as the F-35. With the FAST packs they can achieve a 1,000 NM radius. The F-35 could no doubt achieve a significant increase in range via conformal external fuel. So wait for a later block model to match the F-15E strike radius.

Plus of course none of the F-15, 16 and 18s can match the F-35 for lethality and survivability thanks to the laters mission systems and LO capability.

Just for clarification here, is that 4,500lb warload internal stores in the bays? I assume it is but I want to confirm because if what you say is true then that's a huge improvement in performance, especially when you consider what that implies for a package with external stores available.

I had previously been under the impression that the F-35 offered F-18 style performance with more advanced sig management/sensor and network capabilities, the thought that that kind of raw physical improvement was still possible is quite surprising and impressive.

(apologies for my ignorance but the constant war of words between the 'aye' and the 'nay' side on this one makes it hard to be sure of anything at times)
