    so your saying there there is more pressure and more velocity? but what ever pressure and velocity you state the fact of the matter still remains that Only 18k max of thrust will come from the rear! that’s max thrust! The F-35 should not need and will not need FULL AB 50K of thrust just for light up and away.
    How much does the harrier weight? How much Hot gas is the Av-8 Putting out?
    even with the harriers nozzles spread out that’s still more thrust than the F-35 rear nozzle hitting the ground.

    Specifications (AV-8B+ Harrier II Plus)

    Data from Norden,[19] Aerospaceweb[20]

    General characteristics

    * Crew: 1 pilot
    * Length: 46 ft 4 in (14.12 m)
    * Wingspan: 30 ft 4 in (9.25 m)
    * Height: 11 ft 8 in (3.55 m)
    * Wing area: 243.4 ft² (22.61 m²)
    * Airfoil: supercritical airfoil
    * Empty weight: 13,968 lb (6,340 kg)
    * Loaded weight: 22,950 lb (10,410 kg)
    * Max takeoff weight:
    o Rolling: 31,000 lb (14,100 kg)
    o Vertical: 20,755 lb (9,415 kg)

    http://en.wikipedia.org/wiki/McDonnell_Douglas_AV-8B_Harrier_II

    so the Harriers MAX vert weight is 20K+

    What about any vortices created from the mixture of Hot air and cool air directly under the fuselage? you don’t think this will help? Ill tell you what, you find a F-35B and stand exactly the same distance the rear nozzle is from the main fan. if your hat doesn’t even get blows off Ill stand corrected.

    I stand by my point because I saw a Lockheed demo nearly 100% proving my theory. Ill find it.

    JSF Not Too Hot For Carriers

    March 26th, 2010 2:28 pm

    The STOVL version of the Joint Strike Fighter is not too hot and is not too loud, Marine Commandant Gen. James Conway told DoD Buzz during an editorial board session.

    The most troubling operational challenge that appeared to face the F-35B, next to weight, was reports that it would not be suitable for a carrier or other ship because its exhaust would melt the flight deck. Not so, Conway told reporters from Military?.com. The plane, at 1,500 degrees, is just 18 degrees hotter than a Harrier, he said Thursday.

    He also debunked persistent reports that the JSF will blow the ears off of people living near their flight paths, Conway said that noise levels for the plane are “well in range of legacy aircraft” like the F-22 and the F/A-18 E/F. Bottom line, the JSF ain’t a whisper jet, but communities familiar with existing aircraft shouldn’t have much to worry about.

    On the negative side, Conway noted that “we will lose 28 aircraft over the FYDP” but said he thought the “news for us on JSF is relatively positive” given the recent test successes at Patuxent River.

    On an issue dear to his heart, Conway again praised the Expeditionary Fighting Vehicle. Recent blast tests give him “a high degree of confidence” that the flat-bottomed amphib can protect its crew almost as well as an MRAP.

    He also said he had spoken with Reps. Gene Taylor and Roscoe Bartlett, senior members of the House Armed Services Committee who have expressed strong concerns about EFV, and believed he had convinced them that the flat-bottom design is “an absolute need” to cope with requirements for a vehicle capable of handling Category 4 sea states as it plows in to shore. The EFV must be able to plane, he said, and only a flat bottom lets it do that.

    The Corps expects to take delivery of seven EFVs this summer, he said.

    You should be a politician jonesy 🙂
    You completely ignore the fact that the F35 nozzle/jetpipe is a few inches away from and pointing directly at the deck/ramp for a VL.
    An F14 jet blast is going straight into a purpose built blast deflector…slightly different case methinks !!

    1. I still don’t get how the cold wash coming onto the deck@
    18klbs of thrust isn’t going to help cool the deck! I’m sure if you stood underneath it you would have a bad day
    2. Once again its only few degrees hotter than an AV-8
    3. You will say velocity, but I will say 18k of thrust is still 18k
    No matter how you slice it. It can’t exceed the front end air flow for odvious reasons

    Marines Could Fly CTOL JSF Posted by Bill Sweetman at 9/14/2010

    http://www.aviationweek.com/aw/blogs/de … d=blogDest

    “The US Marine Corps could declare initial operational capability with the Air Force’s F-35A variant of the Joint Strike Fighter, as delays and a major review cast more doubt on the feasibility of meeting a late-2012 IOC date with the F-35B short take-off, vertical landing variant.

    The change is one of the options emerging from an in-depth review of the JSF program, covering the path from now until initial operating capability and full production, Lockheed Martin F-35 general manager Tom Burbage said Monday at the Air Force Association convention at National Harbor, Maryland. This is the review that underlies recent discussions about “rephasing” the F-35 program.

    The technical baseline review (TBR) was commissioned after the JSF’s Nunn-McCurdy breach earlier this year and supports a Defense Acquisition Board review in November. Burbage characterizes the TBR as featuring a different role for Air Force Materiel Command and Naval Air Systems Command, which have hitherto delegated the management of the program to the JSF Program Office.

    The syscoms “are taking a much stronger role as we get to introducing the aircraft to operations”, Burbage said on Monday. Although the TBR also includes an independent manufacturing review, a major focus is on the critical path towards IOC.

    In the case of the F-35B, there are three major items on the critical path, Burbage says. The most important, underpinning the others, is the vertical landing test program. Since March, F-35 BF-1, the only jet instrumented for vertical landings in the initial test phase, has accomplished about half as many vertical landings as scheduled, performing a dozen flights. Burbage says that 42 flights are “the magic number” after which the other F-35B test assets can start flying in vertical mode. BF-2 is being modified with the necessary instrumentation to share BF-1’s role and reach that point more quickly.

    The second key critical path item is the “ready for training” date, which indicates that enough testing has been done to allow the aircraft to be flown safely by operational pilots rather than test pilots, and without the constant monitoring in the test environment. The Marines’ IOC criteria include the availability of 20 trained pilots.

    The third big critical item is ship qualification, which was due to start in the first half of 2011, and Burbage adds that “there is a myriad of other things to be done.”

    The Marines have continued to insist that they will declare IOC in late 2012, and Burbage stresses that it is the operator’s role to make that call. However, he says, one of the options being floated as the TBR continues is “why don’t the Marines fly the CTOL aircraft?”

    The F-35As have so far proven more reliable than the F-35Bs, and the Marine IOC plan has always called for training to start on the F-35A. The Marine inventory also includes combat aircraft such as the F/A-18D and EA-6B, which are for practical purposes land-based in Marine service.

    Therefore, an F-35A IOC could form a bridge to the definitive F-35B – while taking some pressure off the program and giving it more time to fix what are still characterized as component-quality issues with the STOVL jet.”

    http://www.aviationweek.com/aw/blogs/defense/index.jsp?plckController=Blog&plckBlogPage=BlogViewPost&newspaperUserId=27ec4a53-dcc8-42d0-bd3a-01329aef79a7&plckPostId=Blog%3a27ec4a53-dcc8-42d0-bd3a-01329aef79a7Post%3a9ef38fbc-a861-4c83-905b-b344e4987680&plckScript=blogScript&plckElementId=blogDest

    speculation or what?

    I interviewed Tom Burbage later the same day (yesterday) and he insisted he DID NOT say the Marines could declare IOC with F-35As.

    According to Burbage, what he said was that the Marines could begin “up-and-away” CTOL flight training on F-35A while waiting for the STOVL training envelope to be cleared.

    IOC as defined by the Marines requires 20 trained pilots and F-35Bs cleared for both expeditionary (land-based) and ship-based operations, he says.

    The Technical Baseline Review to be completed by mid-October will determine the work required to complete JSF development. It will determine whether the steps required to achieve USMC IOC can be accomplished in the time available. Burbage acknowledges the TBR could force the Marines to push back its IOC.

    But he was adamant he did not say the Marines could hold their 2012 IOC by flying As instead of Bs. Pity, because I think it’s quite a good idea…but on that would send the Pentagon beancounters into a tailspin.

    Why would it have to drop its internal A2G Load?
    How will said Flankers get to the merge any way?
    On another note will it be easier to fit 4 AMRAAms in the main bays and leave the doors for the Aim9-X?

    You’re missing the point, the jassm hit the hospital 30 miles away from where the launcher once was when it fired, and the whole incident went to wikileaks.

    Your still missing the point, the F-35 was in egress an couldn’t get to the launcher so there was a hand off. If 1 F-35 sees the launch then every shooter on the battle field will have the data in seconds. and someone was spot on for correcting me that using a munition with a IR terminal seeker would keep collateral damage down, touche. My point is that the F-35 is not just a shooter but a node. As far as hiding in caves goes, those are not hard to close down after they see a few of there m8s buried alive they might be reluctant to come out and play. But you prove my point even further concerning the F-35. its a data sharing scud hunting machine built for this type of work. The pilot doesn’t have to spot a tel with his mark 1 eye ball. If he fly’s over it, its likely that the AESA will spot it. If they don’t come out to play then the mission is still a success.

    At 800mi the launch is well under the horizon, and even if you did instantly locate the launch point the launcher would be long gone by the time a striker got to it.

    I think you are all missing the point.

    1. F-35 detects Iran missile launch 200 miles out but is RTB.

    2. The F-35 relays the data to other shooters in theater

    3. A B-1 with jassm is in launch range. 100 miles out.

    4. launcher dies

    Its simply repeating whats already known.

    1. Its the IPP causing issues.

    2. that the IPP needs design changes

    3. that the F-35 exhaust is only a few degrees above a harrier

    4. that bases will have to be prepped to accomadate the F-35 becaue of the IPP

    I don’t get how you guys keep saying that the exhaust is at a higher velocity.
    my math is terrible, but doesn’t velocity = more Pounds per square inch?
    How do you have twice the velocity but still only max out at 18k Lbs of thrust? how do you have twice the velocity but only 10 degrees more of heat? its not adding up.

    1. That article is from march of this year. the program has since then been restructured

    A senior Department of Defense official says Lockheed Martin is now on track to reduce the cost of each F-35 by as much as 6.25%, only four months after the programme confirmed a major cost breach.

    The remarks by Frank Kendall, principal deputy undersecretary of defense for acquisition, technology and logistics, represent a massive turnaround by the DoD’s leadership since reporting a Nunn-McCurdy cost overrun in June and restructuring the programme last February.

    Instead, Kendall, addressing the Common Defense (ComDef) 2010 conference on 8 September, cited the F-35 as a key example of what Secretary of Defense Robert Gates means about making the defence industry produce more with less.

    “If we can only afford 80 F-35s every year now,” Kendall asked, “can we afford 85?”

    It is not clear if Kendall was referring to a specific future order or if he was speaking generically, but the US Air Force currently plans to buy 80 F-35As per year at peak rates.

    “I don’t think that’s an unrealistic example,” Kendall added. “I think we are on the path to do exactly that.”

    Kendall’s fresh dose of optimism on F-35 costs comes as DoD and Lockheed officials continue protracted negotiations over the fourth yearly contract for low rate production. Lockheed has agreed to convert contract terms from a “cost-plus” to fixed-price-incentive fee structure two years earlier than scheduled, but the details have delayed contract signing by at least three months.

    In late May, the DoD reported that internal cost projections have soared since 2002, with the average cost of each Joint Strike Fighter rising from $50 million to $92.4 million over that period. The cost overrun was blamed on several factors, including the US Navy’s decision in 2002 to slash orders by 409 jets, inflation and unexpected labour and manufacturing cost increases.

    At the time, a senior DoD official told reporters that “we’re going to scrub every column of cost in this programme and try to restore it as a close as possible to what a decade ago the department said it was going to cost”.

    Lockheed officials have consistently maintained that DoD cost projections for the F-35 programme were inaccurate, with internal estimates being as much as 20% lower.

    Part of the DoD’s restructuring plan last April called for Lockheed to adopt a buy-to-budget strategy. In particular, it slashed five of the 48 jets in next year’s budget, but Lockheed could still deliver all 48 for the same price as 43.
