Broncazonk said:"This is going to have a big tactical impact," one highly experienced officer says. "Anytime you have to lower performance standards, the capability of what the airframe can do goes down as well."
The US Department of Defense's decision to relax the sustained turn performance of all three variants of the F-35 was revealed earlier this month in the Pentagon's Director of Operational Test and Evaluation 2012 report. Turn performance for the US Air Force's F-35A was reduced from 5.3 sustained g's to 4.6 sustained g's. The F-35B had its sustained g's cut from five to 4.5 g's, while the US Navy variant had its turn performance truncated from 5.1 to five sustained g's. Acceleration times from Mach 0.8 to Mach 1.2 were extended by eight seconds, 16 seconds and 43 seconds for the A, B and C-models respectively. The baseline standard used for the comparison was a clean Lockheed F-16 Block 50 with two wingtip Raytheon AIM-120 AMRAAMs. "What an embarrassment, and there will be obvious tactical implications. Having a maximum sustained turn performance of less than 5g is the equivalent of an [McDonnell Douglas] F-4 or an [Northrop] F-5," another highly experienced fighter pilot says. "[It's] certainly not anywhere near the performance of most fourth and fifth-generation aircraft."
At higher altitudes, the reduced performance will directly impact survivability against advanced Russian-designed "double-digit" surface-to-air missile (SAM) systems such as the Almaz-Antey S-300PMU2 (also called the SA-20 Gargoyle by the North Atlantic Treaty Organization), the pilot says. At lower altitudes, where fighters might operate in for the close air support or forward air control role, the reduced airframe performance will place pilots at increased risk against shorter-range SAMs and anti-aircraft artillery.
Most egregious is the F-35C-model's drastically reduced transonic acceleration capabilities. "That [43 seconds] is a massive amount of time, and assuming you are in afterburner for acceleration, it's going to cost you even more gas," the pilot says. "This will directly impact tactical execution, and not in a good way."
Pilots typically make the decision to trade a very high rate of fuel consumption for supersonic airspeeds for one of two reasons. "They are either getting ready to kill something or they are trying to defend against something [that's trying to kill] them," the pilot says. "Every second counts in both of those scenarios. The longer it takes, the more compressed the battle space gets. That is not a good thing."

Certainly a fair point, a more logical comparison would be with an F-16 with six AMRAAMs as that is what the F-35 is said to be able to carry internally- if the configuration is ever cleared. With that said, given that most of the avionics and comms stuff in the F-35 can be retrofitted to legacy platforms the F-35 should be all about improved flight performance and signature reduction. If it is now only offering a major advance in one of those areas it does lessen the overall value of the project.
Broncazonk said:Finally. The truth about the F-35 is finally starting to come out. I can't wait to see how the paid Lockheed Martin internet forum "opinion makers" on this list and others will spin this.
Broncazonk said:Once engaged within visual range, given the F-35's limitations and relative strengths, turning should be minimized in favor of using the jet's Northrop Grumman AAQ-37 distributed aperture system of infrared cameras, helmet-mounted display and high off-boresight missiles to engage the enemy aircraft. If a turning fight is unavoidable, the F-35 has good instantaneous turn performance and good high angle of attack (50°AOA limit) performance comparable to a Boeing F/A-18 Hornet, which means a similar strategy could be adopted if one finds him or herself in such a situation.
But much of the discussion is theoretical at this point, the F-35 has not been operationally tested, nor have tactics been developed for the aircraft's usage. How the aircraft will eventually fare once fully developed and fielded is an open question.
That means that pilots won't be able to fly the F-35 like an F-22 Raptor or even an F-15 (or any other fighter for that matter), it has to be flown like a JSF. Tactics will emphasize stealth and sensor capabilities, says Col Andy Toth, commander of the 33rd Fighter Wing at Eglin AFB, Florida, which is the first DOD F-35 training unit.
"The advantage of the F-35 is a result of being a 5th generation platform and an evolution in technology. Stealth characteristics and sensor fusion will enable it to get in to a target relatively undetected, have the ability to strike a ground asset or engage an enemy and exit the scenario without the threat even knowing it was there," Toth says. "We will continue to work, as the system comes online, to develop tactics that take advantage of the 5th generation capability much like specific tactics were developed for the F-22, different from fourth generation platforms."
Those tactics will inevitably emphasize beyond visual range combat. "Between [the AIM-9X], DAS [distributed aperture system] and the helmet, you deserve to die if you take this thing to the merge," a friend of mine, who is a former naval aviator, told me bluntly after I asked him for feedback on the main article. "I'm sure someone trotted out the 'F-4/Gun' story, but the reality is that the ROE [rules of engagement] that was in place in the 'Nam that drove the need for the gun... ROE that put the F-4 in an environment that made the AIM-7 [Sparrow semi-active radar guided missile] terribly unreliable to start."
But even the best-laid battle plans can fall by the wayside upon first contact with the enemy. "You can only do so much with tactics and sensors when the entire air vehicle is at a disadvantage," warns one highly experienced fighter pilot. "It's going to be interesting to see if tactics can make up for the F-35's shortfalls."

The truth is Lockmart promised more than they could deliver, and they can get away with whatever they please (as long as it doesn't impact the bottom line of the next quarter) because there is no alternative. And so half the airforces of NATO are held hostage and the warfighter does not get what it was promised.

The F-35 program is proof that a whole new idea of incentives and accountability is in order.

Purely my humble opinion, but I have always felt that two fundamental mistakes were made in the JSF programme:
1) Effectively making whoever won the programme a monopolist on fast jet programmes for two decades meaning there were no other options if things started to go wrong. F-35 can not die because any 5th gen replacement aside from even more expensive to operate F-22s (and as that aircraft's upgrade funding shows it would need a lot of development) would be a decade or more away. Splitting out separate USN and USAF programmes- perhaps more akin to the LWF programme, would have kept an element of fear in it for the competitors. Think F-110 Spectre killing F-106A and F-105, far from an exact comparison I admit but hopefully it demonstrates my point.
2) The down-select was made far too early; Lockheed was selected on the basis of what was little more than technology demonstrator rather than a full prototype, essentially they won the contract, were given a position of monopoly and then they got to develop a product without any competition.
Whatever you think of Lockheed and the F-35 one thing is clear; Lockheed knows that there is only ever going to be X amount of money (whatever amount that turns out to be) available for the F-35 programme and over Y number of years. It does not really matter to Lockheed what the end unit price is or what portion of X is spent on RDT&E versus procurement as it all ends up under the heading of revenue on their balance sheet whilst their monopolist position in the western 5th gen market means they are assured 100% of X- whatever it turns out to be.

It is if you compare the USMC F-35B buy to the combined USAF, USN and USMC F-35A/C requirement; 340 versus 2,103. I am not saying it is not an important requirement, it is, but it is still a requirement for only a minority of the US F-35 volume requirement.

In that case you may as well lump the F-35C in there as well and say that "sea-basing is a minority requirement". :![]()

Sea based F-35C didn't dictate the odd fuselage layout common to all three variants. It didn't force F-35A or F-35B to suffer delays because F-35C can't actually take off from carriers, needed to be substantially revised, and forced the already satsifactory F-35A and F-35B to accept the same changes in the name of "commonality" for sake of appearences.

I still can't believe this program wasn't cancelled already out of abject embarassment. Nevermind that damn near every TLR for the program was way off and a hell of a lot of heads should have rolled for it. This program has been one of the greatest failures of management at every level that I have ever seen, both on the corporate and government side.
I would cancel the A and the C and let the Marines do whatever they need to to keep the B variant, including stripping out capabilities that aren't ready and won't be ready for another ten years anyway.
Then I would start a new program based on the Sikorsky approach to the S-97. I would have the few airframers we have left design a fighter first, with attack capability and a basic RADAR ECM system that actually works. Anything else would have to earn it's way on to the airframe by first proving it actually works in reality, not a computer sim or powerpoint war, and that it was affordable.
while Sikorsky has an already outdated mockup pf the S-97 at its AUSA display, the Raider doesn't actually exist yet. The company expects to fly the first of two prototypes it is building in 2014.
first proving it actually works in reality,
But that would make sense. Lets keep throwing money into the most expensive combat turd in history.
Hey guys, send me a few hundreds of billion dollars. I can design and build you a panacea tacair plane twice as good as the F-35. I promise!![]()
SpudmanWP said:That's the difference between a development contract vs a production contract.
If LM had reached the goal of X-gs at Y-speed with Z-fuelrate in SDD and then failed to deliver that in production... you would have a point.
In an SDD program there are certain things that are "required" and others that are "goals". The Customer then gets to decide that if a requirement or goal looks like it will be missed, they can either spend more money to fix it now (which will result in an IOC delay) or they can go to IOC now with what they have and can get back to the original requirement/goal at a later upgrade.
So you're willing to pay for two complete development programs?JFC Fuller said:Why not fund two aircraft until they are ready for LRIP, assuming there is no concurrency? That makes the prize the production contract.

For LM, it is actually irrelevant whether they sell one $100 million plane or 100 $1 million ones, they still get $100 million.
Yea the UK requirement was huge, peaking as it did at 150 airframes, well under half even the USMC B requirement.

chuck4 said:SpudmanWP said:And how would any of that be faster or cheaper than what we have now?
Fundamentally, it seem to me much of the technical problem with JSF can be attributed to lousy upstream engineering. Early technical specifications were set, and early engineering promises and decisions were made based short sighted considerations, and designed to perhaps meeting some short term (perhaps non-technical) objective rather than well considered to best improve the final product. The perception that any resulting deficiency could always be either forced on the procurement authority, or be fixed at the expense of the procurement authority because LM was the sole contractor and the procurement authority has nowhere else to go undoubtedly encouraged this "style" of project "management".
With competitive development, each vendor would live in fear of losing the main source of profit - production contract - if the development portion is not managed better than the other guys'. The procurement authority has somewhere else to go. Therefore vendor would be more motivated to make better upstream engineering decisions because there is no chance to keep the production contract and fix any mistakes made early on further down stream at government expense. The competition will go on for long enough to allow bad engineering decisions made early on to become menifest. So there is no benefit to making short sighted engineering decisions that makes the project look better at the time of vendor selection but which would explode before the project enters production. The vendors with too many bad engineering decisions will be shown the door. Their engineeing errors of judgement won't be fixed at government expense. The project will go on based on the team that didn't make those errors in the first place.

So what you are saying is that by fully funding and backing the F-16 (which had an awful lot of problems in its early days) the USAF missed its chance to develop another aircraft? Or the Navy with the F-14?
I don't know we don't traditionally do it that. We make our pick and we build it. No one seemed to screaming and yelling when the USN was developing the super bug all by its lonesome and it ran into problems. Or the F-22? C-17?
As much as we are praising competition its A. largely government funded B. Government doesn't move at a speed that can actually take advantage of competition. C. Companies depend on making long term plans D. The military also needs to know these things E. What makes us so sure that the government doesn't keep competition moving and the "wrong" plane still wins?
The same government that thought of the JSF and then picked the X-35 over the X-32 is now suddenly going to fund two programs and nimbly use the competition to always make the right decision? :Good luck with that.
chuck4 said:The difference is with JSF, the risk to the services, especially airforce, is much greater. F-16 project was undertaken when the AF had a full F-15 program, a large inventory of relatively low hour airframes of previous generation, and a Northrop alternative that could still be resurrected.

But even then the USAF stuck with the F-16. They could have as you said thrown in the towel, and taken an alternative but they didn't. Same with C-17, F-22, V-22 etc. So you seem more upset that we didn't create a "Bridge" aircraft between the F-16 and F-35. But of course at the time no one minded not spending billions developing and fielding it.
It just seems to be the perception of desperation, even though most military contracts are winner take all despite issues. In case you missed Korea the F-35 is in competition internationally.
Would there be an F-14 Tomcat after 11 of 12 prototypes crashed? Chuck?,Under your idea how can you not award the contract to the F-14's competitor under those circumstances? What if the competitor is not as good as the F-14 and is overbudget, but has yet to crash any prototypes?
The F-X program picked the F-15 without even a flying prototype. Maybe we need LESS competition?
