    Pretty sure it’s a wild guess.

    No, not a wild guess…

    Also amazingly two tanks are not shown here on the graphic used for the swiss competition,

    http://3.bp.blogspot.com/-oaWYzcZcnHA/UKiGNe6_DmI/AAAAAAAAAD0/npYs1LEcNno/s1600/swissgripene_load.jpg

    or here from a graphic straight from SAAB GRIPEN.COM Saab’s website available here http://saab.com/air/gripen-fighter-system/gripen/gripen/the-fighter/Gripen-NG/

    Now call me crazy but don’t you think if the Gripen E had the capability to carry two tanks on the fuselage stations they would advertise it on their own website, especially given they are happy to claim a whole bunch of other things…

    Also it might be able to carry 2 450 gal tanks on the wings and 2 290 gal on the fuselage:

    Pretty sure the two tanks on the belly idea was shelved.

    YRIC, or it was someone with lotsa fantasy visualizing how a ‘typical’ fight turns out,
    certainly not an official quote

    I will find it and post it up but to clarify that is why I used IIRC. If you understand what the acronym means it acknowledges there is a lack of confidence in the memory.

    yes, obviously :very_drunk:

    Sure, and it says that where?

    By the way, appreciate the endearing nickname…

    time in combat is never provided, its impossible to predict or even predict average.
    just time on station is possible to state.

    Actually, decent range estimations give a description of the combat time. IIRC one of the range estimations provided for a couple of 6g turns and a minute of burner use.

    Time on station is also a somewhat meaningless metric as we don’t know how that time is calculated. Is the aircraft racetracking, is it trading altitude for longer on station time, it is in a very low energy state and would take time to reach a tactically significant speed?

    did it ever occur to you that a typical A2A configuration is =/= from max combat air patrol range ?
    guess not

    Well aware of different mission configurations but Saab decided not to let us know what they are. Instead they can hide behind the ambiguity as described.

    there was never a new fighter built when drag was as known as it is on gripen E,
    yet predictions came within 10%, only fighter in living memory that fell short of 10% was F-35 performance,
    and even then it was more of an objective or guideline than actual prediction,
    and truth to be told most predicted the objectives was just hype anyway, even F-35 became as predicted,
    more or less, or just less

    Of course, they knew so much already they predicted a 15% OEW increase before they started building the jet…

    But this is all academic as the Gripen is the least likely to be chosen by Canada for a host of reasons other than Saab’s claims.

    if anything, i’d sooner expect a slight improvement, on the odd chance perfection can be improved upon

    LOL, you should change your signature block.

    A couple of great contradictions in that document. Page 3 tells us with a typical air to air config the jet will fly for two hours. Then page 7 tells us that on a combat air patrol the jet has a 500nm radius and 100min on station. See an issue there? The text on page 7 also states with a typical air to air config it can patrol for over two hours. No loads, weights, mission profiles or time in combat are provided.

    Of course given the Gripen E has never flown all of this is just marketing…

    Instead of making your usual unsupported claims; here is a good exercise for you:

    Post the Gripen E/F combat radius (CAP, or AtA mission however they state it), from the Brazil competition, and recent power points.

    Then, get the F-35 range on a similar mission profile and post that as well.

    I know the figures for both (estimated numbers from released data). Let’s see what the stated manufacter claims you can come up with show, and if it supports your above statement.

    Should also get him to factor in the 15% OEW increase that the Gripen E has had since those Brazilian figures were published.

    Yes but Vietnam was also the last time western air power was seriously challenged. Exceptions are some engagements here and there like in Desert Storm were tanks were immediately dropped when needed. But thats what WRM tanks are there for.
    Also, there were some stories iirc of Israeli drop tanks claimed to be remnants of shot down jets. Getting rid of everything that can be jettisoned is stil standard practice when in trouble, I guess.

    Sure there are standard rules for peacetime and rules for conflict. The issue is we know USAF jets don’t have an unlimited supply and they are going to have more than most, given their budgets. I would certainly dump my tanks if it meant I had a greater chance to survive an engagement. What it doesn’t provide it great longevity for the fighter force as a whole. It would likely be quite soon into a conflict that the squadron couldn’t execute missions assigned by the AOC because with so many dumped tanks they don’t have the legs to get execute. Alternatively, tankers are required closer to the FEBA, placing those assets in greater harm. The tanks being large and difficult to transport doesn’t bode well for resupply either.

    Eyeball mk1 strikes again!

    There used to be a great website that showed the comparison of various cars and trucks with respect to the drag coefficient, sadly it has been removed by the author.

    Below is a good example though of how looks mean little when it comes to drag, such as the Jaguar E having a higher drag coefficient than a Volkswagen Microbus or a Ford Escort.

    on the contrary, the parameters are better known than any other new fighter,
    in fact nothing is unknown

    Of course, I forgot that the Gripen E has flown, conducted an extensive test program and all the assumptions, weight increases and test measurements and have been factored into the range calculations…

    no, canada isnt guaranteed to sell a single screw, and even if they could, it still doesnt cover operational cost alone,
    its a money sink either way you cut it

    Except economic benefit was a major consideration in 1979 and the Canadian Government have stated repeatedly that the contribution the next fighter makes to the Canadian economy is critical to the selection. In case you didn’t read it, this is from the Canadian Government press release,

    This is about getting our women and men in uniform the equipment they need to do their jobs and protect Canadians in the most effective way possible while maximizing economic benefits for the middle class and those working hard to join it.

    “Today’s announcement demonstrates how our Government is working to generate strong and sustained economic benefits for Canadian companies. The replacement of Canada’s CF-18 fleet will help grow Canada’s aerospace sector, create high-value jobs, and support Canadian innovation.”

    Going from 10.7m to 7.7m would be a 30% reduction, so the carrier could carry about 35% more aircraft. I think for a CVN there is enough space for larger aircraft but the STOVL carriers are smaller, so it would make a big difference. Now does the carrier have enough logistics, fuel and weapons for so many F-35Bs that’s another story, the QEs probably, the smaller carriers not sure.

    The STOVL carriers are not STOVL carriers but amphibious assault ships. Their primary purpose is to support amphibious operations and the delivery and support of troops inland. Therefore if the America class operate as Sea Control ships they do so with the understanding that they carry only a certain sized airwing which will still be enough to fulfill that role if required.

    SAAB states combat radius 800 nm +30 min. on station for A2A,
    which edges out F-22 w 2 600 gallon tanks by around 100 nm taken from the pic above,
    under assumption 30 min on station roughly translates into 150 nm for gripen E.
    And 800 nm combat radius for A2G.

    As with the rest of Saab’s figures we need a very large pinch of salt with that claim.

    as far as i know, the only candidates for RCAF are f-35 & f-18E, so we need not contemplate others,
    and the only quantity we need to compare are upfront and operational cost

    Economic input to the Canadian economy is probably the most important “quantity”.

    Wrong.. it’s $78 million unit recurring flyaway in FY2018 dollars.. the corresponding price of the F-35C is ~$130 million (don’t remember which FY).

    And yet no export customer is offerred a price anywhere near that low… The RAAF and the Kuwaitis were both above $100 mill with additional suppprt contracts after that.

    Then of course you need to factor in the additional range, safer landing, superior sensor fit and two orders of magnitude lower RCS.

    The safer landing is a massive deal, USN pilots can now focus on fighting with the jet instead of prowess being ranked by how well you land.

    Danemark is comparable to Quebec in size, with easy access to flat lands and quite a mild climate in comparison (that’s where the gulf stream ends, warming the climate of whole western europe), while sweden is bigger than that, the places they fly from are much closer to each other and allow for a much easier tracking (and SAR if necessary) than the canadian north…

    Canada does not have fighter jets permentantly based in the north. They rotate small deployments of jets, usually four, through one of four bare bases in the summer, bases which were built essentially with US money in the 80s. Previous to that, Canadian fighter jets rarely flew north in the latitudes you assume.

    Canadian operations in the north are detailed here,
    http://www.forces.gc.ca/en/operations-canada-north-america/north.page

    As for the earlier contention on strike missions, if we calculated how many times Canadian fighter aircraft have intercepted aircraft in north latitudes you will find it is similar or less than the number of operational strike sorties conducted supporting overseas deployments.

    i’m just wondering why everyone is so dismissive on F-16, not just here but various air forces around the world too,
    canada will not have much resistance to win air superiority over arctic/canada,
    and its still a better fighter-interceptor than F-18, while simultaneously being cheaper,
    so why would f-18 be an option but f-16 isnt ?

    Economic value to the Canadian economy for a start, second that the airframe is required to serve for the next 40 years from 2025. Is there a single F-16 operator anywhere who will use the F-16 25 years from then, let alone a teir 1 air force?

    The other contender? F-14, F-15, F-18L, Mirages and Tornado were in the race aswell, at least initially.
    2 engines was I think one the main reasons the Hornet was chosen over the F-16 in the end. Late 70s was a different time though.

    The two down selected candidates were the F-16 and F-18.

    As already discussed much earlier in the thread, two engines was a reason but not the main reason. The ability of the hornet for multi role opeations, including BVR, from day one was one major reason, the better industrial deal offered by McDD the other.
