    Our two Frenchmen making donuts in the sky to make sure they have a chance to spot them, tells the story by itself.

    1. What is the RoC of the F35?
    2 Agility is defined by the ability and rates to move from one plan to another (vector and trajectory). With extreme alpha and beta values compared to a Eurocanard (we are in the 50deg range in pitch and dwarfing values in beta), what makes you think that agility is lagging somewhat? Oh, let me guess, Bill Sweetman?

    If “speed, climb, agility” was a preset formula that you ‘d use without thinking much, it’s a rather stunning use of such on an aviation forum.

    I wrote :

    with a vstol stealth aircraft

    What can led anyone into confusion (this I wrote latter also).

    If we look at Switzerland geography, there are no needs to have a range of 590nm. This is 3.5 time the span of the entire country!

    With 13000/2.5 lb of fuel (2.5 and not 3.5 to take in effect the invariable T.O + Climb + Land expense of fuel), an armed F35lb can cover 590/3.5=166nm mission, hence cover a 300 km country.

    13000/2.5=5200lb, which by itself, is nearly reaching the bring back capability of the aircraft**.

    It’s arithmetic*, not me.

    LAst but not least, it would be interesting to know how much at reduce fuel does Switzerland operates its F18 if any.

    *hairy, yes but representative somewhat.
    ** In A2A, everybody will agree

    I am mainly focusing on combined STOL and VTOL where needed, yes. This is why I speak about plateaus and not parking lots 😉

    Can you please repost a link of the 35B perfs? I mean, the RAF plans to use it as well and they have among the most experience in this kind of operation.

    If the Belgian Gov pays for it, certainly. An then it’s about Sabca to do the job… And who is behind Sabca? Let’s be realistic, there is enough ground for a deal.

    They’re stealthy — that’s why you can’t see them.

    (Sorry, couldn’t resist.)

    I wonder how the crew manage to get on board hence (Houston, we have lost sight of the hatch). 😉

    STOVL, not VTOL. They’re not the same thing. That is exactly my point. I went on about it at some length, & you’ve just ignored it completely.

    I did understood. But you failed to notice past my wording mistake that a Swiss F35B won’t operate at maximum permissible weight in a typical mission. Either load-out will be restricted to A2A and few A2G at first day of war (yes, the buy is all about planing a war on their own ground at first), either the fuel will be restricted to gain that margin in Operation readiness that I am talking about.

    For sure, if the SAF want to intercept airliners faster than its neighbors, a Typhoon or a Mig29 will do the trick better than anything else (Don’t forget the SH that was designed for this also). If they want to bomb Paris or Berlin or the Gulf os Sirte, a Rafale will do the trick better. If they plan to join NATO without fully stepping in it, a Gripen will be the thing… [CaricaturingMode=OFF]

    But then, if they want to have a resilient airforce able to support the attrition war on their own ground, then a stealth thing, able to operate hiddenly from a tinny inhabited plateau is the real deal.

    Don’t forget that it’s all about answering a need. It’s not because some have made a job of dragging their compagnies all over the world after any expensive competition open to choose an aircraft* that we have to stick here to that motto.

    A two bases country that intend to defend itself valley after valley (if this is still the doctrine) does not need a Typhoon that will be pluck on the ground the first day of war. It needs resilience at first.
    And then, I doubt that any of the modern design that are envisaged here won’t be able to fulfill the airliner intercepting mission.

    Australia and France eye collaboration on special forces NH90 helos

    Meanwhile, in Australia…

    The Tiger has had a troubled history � essential upgrades are programmed to maintain the capability�s effectiveness. Defence will invest in a future armed reconnaissance capability to replace the Tiger, which could include manned or unmanned systems or a combination of both, to be introduced from the mid-2020s.�

    We have discussed this before but a pod is more difficult to build and hence offer less cap than an internal unit. Usually pods are adaptable to many platforms, what pull their price down and help bring more capacities for the same price.
    With the F35, we are dealing with systems that de-facto beneficiate from the program scale effect, easing the introduction of added perfs at at a given price. The fact also that the 35 is going to be hegemonic as a front line fighter will increases that margin by simply rarefying the number of fighter in need for a system upgrade.

    The pod is not dead, but death by suffocation is near.

    It can leads someone into confusion but I am referring to some particular geographical location as mentioned to exemplify that all presumed tactical basing won’t be in high altitude terrain.
    VToL or SToVL is doable in CH as much as it is in the California deserts or in Nevada. Dissemination of base location will be much more dense than with road basing, drastically increasing resilience at a given cost. Hence, F35B will be in overall much cheaper for the same effect.

    McCain Threatens To Block New Air Force Bomber

    “Silicon Valley built the latest one of these without a cost-plus contract,” he said of his smartphone. “ ‘Well, the technology is such that we’re not sure of it.’ Somehow the commercial side can do this without a cost-plus contract. It is an evil that has grown and grown and grown over the years, and I will not stand for it on any weapon system.

    Silicon Valley specializes on building high ROI products. The cost of serial manufacturing a smartphone is 30% that of the pricing in most advertised case.

    The risk inherent to R&D and productions are much lower and the possibility of admortizing a loss following an error are manifold than that of an airplane. It’s not like the aero industry has not lost any Giants in the past with that kind of thinking.
    Now, let’s say that Northrop take Senator Mc Cain by the words, who will be comfortable with that kind of profit margin?

    So the Marines that plan to forward locate their 35 with STOVL and have built the logistical ressources to do just this are just dreaming?

    Also a plateau in CH is not the same as in the Himalaya. From my mem:
    Alt of a plateau around Geneva is 600m
    Alt around Interlaken: 900/1000m
    Alt around Neuchatel: 800m

    F-35B can take off vertically. The STOVL requirement was 550ft (10knt wod) now 600ft KPP with full fuel and 5,500lbs payload. Obviously, considering the VLBB requirements, it can take off vertically with some weapons and fuel (in an emergency)- obviously not enough to fly a significant distance.

    OK guys, you’ve spotted it. STOVL: SHORT TAKE-OFF AND VERTICAL LANDING. The culprit will copies 50 lines of this.

    Regarding range and Switzerland, believe me, you can spent more time climbing back to your own chalet after work than crossing the entire country!
