    They are very curved. But they don’t look very curved in some angles. At this vantage point, they are very curved. Nothing looks lined up

    yeah, it’s this amazing new aerodynamic trick known as area ruling. Brilliant minds back in the 1950’s must have mused on compressor face radar reflectivity, or not. I, for one, am going to assume that Sukhoi has done pole testing and found a suitable medium between airflow and RCS concerns.

    No, they’re just different aircraft, the first one’s a C, the second a B model.
    The angles are different on the other wing pylons aswell.

    Hmm, you might have something there. The C has a different Camber with more of a downward twist (mentioned in Air & Space Power journal 2003, to improve handling). There is no doubt there is a difference:

    As for the rail having an outward bend, it may simply have been a separation issue or buffet. Here was an old post on elements of power musing this point:

    Pylon isnt canted, the attached rail is. I’m curious if this is an Aim-9 specific issue.

    I cant seem to find information regarding wing tip pylon modification there , Google Fu doesnt seem to help either
    So do they change the pylon from canted downward to horizontal or other way round ?

    I can’t either. I remember reading about the modification. By the time of the first external weapons pictures, it appears that the current outward canted rail was fitted to the pylon. Will dig for more in a bit. I can tell you in the original weapon configuration schematics circa 2007-8, stations 1,11 are shown with a completely vertical pylon/rail mounting.

    Not wingtip modification. The pylon was changed probably due to vibration or separation issues, this was pretty early on I believe. This is the manufactuer of the F-35 pylons with the different types:

    Nahh , one of them parallel to the nose ,the other isnt

    When was the first pic taken? The outer pylon did get modified, current pylon closeup:

    On the subject on ELINT and A2/AD in Syria and Europe.
    Here is what U.S. Air Force Gen. Philip Breedlove, commander of U.S. European Command told the House Armed Services Committee on February 25:

    http://nationalinterest.org/blog/the-buzz/electronic-warfare-russias-gains-threaten-disconnect-us-15323

    Would suggest reading the actual HASC report. The impressions Breedlove gives are far different in full context than what this article suggests. Dave Majumdar uses some creative cut and paste on the actual comments of Breedlove (as is Majumdar’s habit since leaving Flightglobal).

    This whole section is utter B.S.- “One area that he highlighted was the North Atlantic where the Russian Navy massively increased its activity to nearly Cold War levels.” The Soviets had around 170 submarines in 1989, today there are roughly 38 nuclear submarines (SSBN, SSN, SSGN) active, fitting out, or being re-activated. There are around 20-22 Conventional submarines in service. Yes, sortie rates are way up over the 90’s and early 2000’s. Claiming “nearly cold war levels” of deployment even in the North Atlantic is an exaggeration. This article is the typical “chicken little” piece whipping up fears for no reason.

    1.5% of GDP does not allow for recap of navy, airforce, and army at the same time. The Navy needs to replace the Ula class starting by 2019, and there is no doubt the F-16MLU need a replacement. Same issue all over Nato, peace dividend of 1990 leads to bow wave in 2010’s.

    Impressed with the J-20 fit and finish. The design has come a long way. That, and frankly this is one bird that looks better in the air than on a runway.

    Its very easy to modify ANY aircraft to be neutrally unstable like the F-16, its just a matter of shifting the CoG back to match the CoL

    Well, except that the F-16 has negative static stability. CoG is not at aerodynamic center. How aft and at what loads? No idea.

    Not like Dassault could have simply made this modification to the F1 at the time being discussed. FBW systems took considerable time to develop. As Saab found out, was still required to tailor system to particular aircraft.

    If you’re a civilian, you shouldn’t still be in Aleppo.

    Same problem as Mosul. In some cases they can’t get out, some are being prevented from leaving, some don’t want to leave because it’s their home and there’s nowhere for them to go.

    In your nice moving speech you say you are against undue murder of civilians, but in reality you don’t give damn.. You have it all nicely polarized, when Russians are doing it, you’re the first to point a finger, when the US are doing it, you look the other way.. I can’t wait to hear your excuses when US bombs start killing civilians (among others) in Mosul.

    Thank you for telling me what I think. But I think you just nicely wrapped your own bias in a ribbon for all of us: “Russian bombing of Aleppo is justified and only killing those bad terrorists, but the US actions are an outrage”.

    Think it is safe to say that many civilians will be killed in Mosul, especially considering the sectarian nature of the conflict. US bombs will kill civilians there as well. But if you think there will be the wholesale area bombing with unguided munitions (Thermobaric, CM, WP munitions) as is happening in Aleppo, your delusional as well as bias.

    What an incredibly stupid and ignorant report.

    The “Block Buy” that is being proposed is NOT a multi-year procurement contract. Congress even said so. t

    Spud, if you want to truly be amused, look up the author’s other works. He a master of pseudo-science. He’s a bit of a joke, but he writes negative articles about the F-35 so in the continued tradition of lowest common denominator defense journalism, the article is linked to and quoted.

    TR1 I respect you and what you are saying and don’t entirely disagree.

    However, it is not just “US propaganda”. Being one of the rare breeds who reads reports and news from a variety of sources and nations, there is little doubt about the level of destruction being leveled on Aleppo. And yes, as does ISIS, the opposition in Aleppo has little incentive to let the civilians out. This is a bad situation, period. I take offense to anyone making excuses for it because of US, UK, or anyone’s previous atrocities.

    No, 760 nm combat radius with warload is for fat kids

    you are confusing C with E, its like confusing F-102 with F-106, two different types

    http://saab.com/globalassets/commercial/air/gripen-fighter-system/gripen-ng/technical-brochure-gripen-ng-english-ver.2-jan-2015_low.pdf

    so there you have it: 800 nm + 30 min+ on station with A2A combat radius,
    or 800 nm with A2G combat radius
    800 nm = 1500 km

    Well, your own sources give a combat radius of 500nmi with internal fuel. Saab gives the Gripen E/F a CAP radius of 559 miles (485nmi). And a total combat radius of 932 miles (782nmi), with EFT’s. So the F-35 beats it in CAP range hands down. What are you talking about exactly? Or did not not think to change miles into nautical miles as everyone else uses? Opps!

    In other words, the F-35 carrying bombs and flying a strike profile outranges the Gripen E/F flying a CAP mission with only missiles by 45 nmi in radius of action.
