    So China can legally supply Ballistic/Cruise missiles to Iran and North Korea since both have domestic missiles of much longer ranges?

    Not accurate ones though.

    That is truly hot air^^ Doubt Germany, France etc will follow suite.
    Hell it looks like IAPO still get avionics from Thales(see Su-30SM of the Knights)
    SSJ have no problemo eighter it seems.

    Such idea is more suited to sound smart at domestic domain.. alltough i question the “smart” quotes.

    Interestly, the RusNavy is deploying the meanest and largest Battle group sinse breakup of SU as we speak, and it will arrive ouitside Syria in a few days, and with that Boris the clovn here is talking about a no flight zone with Kerry.. how truly disepointing..

    US is still tramping around like a headless chicken over Syria. They still have no clear goal(End goal) for Syria.

    Oh, and here is one more from the righteousness club; https://www.youtube.com/watch?v=YoLVysMp2HI

    I’m not seeing Assad and Russia with any clear answers for Syria future, but having to listening to these nutters are too much for me.

    I have to say I don’t approve of current foreign policy, it seems to be about upsetting the status-quo and them blaming and sanctioning Russia if they object/intervene.

    The CAMM is based on the ASRAAM and features TV. The CAMM(A) is intended to be used on aircraft. I don’t know if current ASRAAMs will be upgradable. It will have a datalink, so it will be pretty good for BVR.

    Also interesting regarding internal carriage, the Land and Maritime variants will have folded fins. If they could use those folded fins on the Air variant that could save space Inside the F-35. The problem though I guess is that it couldn’t be rail launched on other planes.

    I don’t think the CAMM does have TVC, you may be confusing the cold launch gas turnover pack for TVC. Also not sure what other upgrades ASRAAM is getting, most of them were obsolescence related.

    it looks like LM claim 8% range improvement for F-35 with DT on the pic above from the norwegian request, so its still apples to apples
    http://forum.keypublishing.com/attachment.php?attachmentid=249021&stc=1&d=1476583463
    then there is also the fact that like all fighters, it was designed for DT for a reason, a modular approach on a mission to mission basis

    how did you arrive to the conclusion every mission is going to be 800 nm ?
    it disqualifies F-35 from ever execute a mission in the first instance, not to mention EF.

    i think CPFH went up since janes study, for all a/c, so while the scale is still valid, the absolute numbers are no longer in the ballpark

    Not really because it’s not carrying as much external fuel. And the optimism of the range figures for an untested NG are also in questionable. Do they include dropping the tanks etc. because the F-35 figure is with retaining the tanks as it was for a recon mission.

    Ever heard of IFR?

    The scale isn’t valid either. I could quote $1/hour for an aircraft that isn’t in service yet. And IIRC the cost was for a Gripen C.

    How did USA get away with supplying Tomahawks and Tridents to UK?

    Are there different rules for US vs other countries?

    Because there was no proliferation of missile technology. No proliferation of the ability to design a missile capable of >300km.

    lbf – pounds-force, i.e. for our purposes a measure of thrust rather than mass.

    kgf – metric counterpart to the above.

    daN – 10 Newtons.

    lbst – I think is short for lbf static, i.e. thrust in sea level static conditions?

    So shouldn’t a kg/kgf.hr figure be the same as a lb/lbf.hr figure or lb/lbst.hr figure?

    That would be a good loadout, all the more that the ASRAAM is going to get a thrust vectoring upgrade. I think the launchers should still be capable of carrying 6 AMRAAM by default. Most air forces that are going to get the F-35 have stockpiles of AMRAAMs.

    I wasn’t aware of any TVC upgrade for ASRAAM.

    In terms of lbf, kgf and daN, could someone explain what exactly a lbst is?

    JSM get 300 nm range and still available for export

    Who to though? That’s the question. The MTCR restrictions don’t apply to everybody.

    MCTR apart, several points: the image you’ve posted is not in fact a photo but a montage, and as such subject to error by the artist with respect to perspective & scale. The JSOW is depicted much further back than the Storm Shadow, so we have depend on the accuracy of the artist, which I would not consider bullet proof. Also, far from all sources quote 0.48m (most say 0.7m+) for its diameter, so assuming a ‘conspiracy theory’ to hide its true range is a bit overwrought. Then there’s the configuration of the warhead – Storm Shadow has a dual tandem BROACH warhead, as opposed to the unitary charge on the Tomahawk which is probably more compact.

    By far the most important reason is one you omitted to quote in your list of specs though:

    Tomahawk

    Engine – Williams F107 turbofan
    Thrust – 3.1kN

    Storm Shadow
    Engine – Microturbo TRI60-30 turbojet
    Thrust – 5.5kN

    So the Storm Shadow has 75% more thrust from an engine with significantly worse (as in about 30% worse!) SFC – your facetious comment in the original post was perhaps closer than you realized. As to why the thrust requirement for Storm Shadow is so much higher despite similar size is something I’ve never seen explained, my personal guess is that it (and the Taurus, which was designed to similar requirements and also has powerful engine) flies a more aggressive terrain following profile for improved survivability (harder manoeuvres).

    My estimate is that the fairly common quotes of 400km range for Storm Shadow and 600km for Taurus (turbofan engine like Tomahawk, albeit more powerful!) are reasonably close.

    Well it flies a little faster than Tomahawk, so maybe that’s why.

    Where do you get your SFC figures from? Thrust is actually 5.3kN and 2.93kN for the Williams F1-7-WR-402.

    Okay so 30% difference in SFC but that doesn’t account for a 7-fold reduction in range and even with the less compact warhead surely the extra internal volume should allow extra fuel, or at least mitigate the warhead.

    This source states 300+nm for Storm Shadow but I would still expect 1,000+km.

    Fuel prices are mostly duty and VAT (and most VAT paid on the duty!), the price of the oil is marginal at best compared to the tax; and I don’t know what the difference in duty was between 2008 and 2016. Also, in 2008, VAT was different, wasn’t it? For a while VAT went down to 15% but is now 20%.

    Also, as I mentioned, the refining costs are quite a factor. In 2008 there was a global glut of refined fuel and low oil prices; in 2016 we have a glut of crude oil but demand for refined fuel is far higher globally than it was in 2008, and we buy refined fuel, not crude oil.

    It’s been down as low as $28.50 though and we still haven’t seen <£1/L. 5% more VAT, so that’s about 5p.

    Yes, because the Google back-taxes in France represent underpayment of taxes over ten years!

    Even the article you linked says that…

    Even is the whole of the ‘tax-dodging’ for the EU was recovered by the UK alone it would barely cover the current UK budget deficit at today’s pound / dollar rate.

    I agree about Amazon (and other mail-order companies). They should pay zero corporation-tax but increased VAT based on delivery address; that would also increase the VAT take from mail-order companies that are actually based abroad.

    And how many companies are there? What about the affect that has on borrowing and interest payments on a cumulative basis?

    Well the UK economy is about 1/6th of the EU, so 1/6th of that $76bn is likely ours, or about $13bn/year. Now add that up over ten years, apply interest on borrowing and you have $130bn extra debt, except each year it’s multiplied by (1+[interest rate/100]). It adds up and that’s just corporation tax alone, not individual taxes.

    So you’re looking to pass the cost on to consumers?

    I disagree.. There hasn’t been a single year of civil war since Syria was recognized as an independent republic in 1944. There were some revolts like military coup in 1961, al-Assad’s coup in 1970 or Muslim Brotherhood uprising in Hama 1982, but nothing major..

    So you think IS and Al-Nusra and Ahrar al-Sham and the moderate rebels, Kurds and Shias, will all just get along?

    You certainly are an optimist. Surely the best possible outcome is to try return to the government that kept it peaceful for 40+ years.

    I’m not going to get drawn into a running battle on this one. I don’t say that Assad is the root of all the problems but certainly ones which have since (the UK parliamentary vote against airstrikes on the Syrian government military infrastructure) developed would not have done so in the same way.

    At that point in time, Russia only felt able to cause obstruction through the Security Council and the UN, whereas the UK/US inaction after chemical weapon use served to demonstrate to Russia that there was no stomach for Western military involvement against Assad.

    We’ve already tried all this before though, Afghanistan, Iraq, Libya. You remove the bad guy and all the even worse guys come out to play. There simply isn’t enough moderate secular rebels in Syria to form a democratically elected government, so what you’ll get at best is an Islamist government, see Egypt for how that ends up. So basically applied to Syria, you get the Syrian regime, minus Assad back in control and that’s actually the best possible outcome. For worst possible outcomes, see Libya and Iraq.

    You’d better define ‘after the 2008 crash’ and provide a source that shows fuel at £0.90/litre with oil at $78/barrel to prove that because I couldn’t find one!

    http://www.theaa.com/motoring_advice/fuel/aa-fuel-price-review-2008.html

    Fairly easy to Google it. Oct 2008, $74, price at pumps 9Xp/L locally.

    http://www.macrotrends.net/1369/crude-oil-price-history-chart

    Look at Oct even in your link. 106p/L @ $67/bbl, now 110p/L at $50/bbl.

    We’ve been below th Dec 2008 oil price and never seen anything below £1/L never mind 89p.

    Now given your argument that it’s mostly tax, actual inflation should only have a very small affect on the price at the pumps.
