    @Sign
    Let alone that a 1000 km range increase with just one additional drop tank is extremely optimistic to stay polite. If max ferry range with for EDTs is stated with some 4000+ km, how do you explain that a single drop tank would increase the range by 1000 km, but three more tanks only increase range by some 500+ km? Come on apply some common sense and you’ll see that this claim is in fact completely unrealistic!

    I have no idea as the program goes, at the moment, but Demo A/C has flown with the bigger droptanks. From from there its an straitforward calculation before an empiric verification.
    and its on offer:

    So who has the best data for such a claim? The company who offer it or a guy on a internetforum saying its unrealistic?

    All right, for the wish of Mr.Sign, let me make another “fair comparison” for Mr.Sign:

    According to the Mr.Sign’s data (Personally, I think this data is very pro-Typhoon and extremely unfair to Rafale ~ Do someone here really believe that the fuel consumption of Rafale is > 16% higher than Eurofighter ??):

    EF-2000: 4,996 kg fuel for 2600km ferry range –> 3,843 kg fuel for 2,000 km ferry range.

    Gripen NG: 3,500 kg fuel for 2500km ferry range –> 2,800 kg fuel for 2,000 km ferry range.

    F-18: 6,780 kg fuel for 2,346km ferry range –> 5,780 kg fuel for 2,000 km ferry range.

    Rafale: 4,700 kg fuel 2,100km ferry range –> 4,476 kg fuel for 2,000 km ferry range.

    Mig-35: 4,800 kg fuel for 2,000 km ferry range.

    F-16: 3,160 kg fuel for 1,750km ferry range –> 3,611 kg fuel for 2,000 km ferry range.

    And according to the data mentioned above:

    Empty Weight:
    F/A-18E: 14,552 kg
    MIG-35: 12,000 kg
    EF-2000: 11,150 kg
    Rafale C: 10,000 kg
    F-16 IN: 9,979 kg
    Gripen NG: 7,100 kg

    Internal Fuel:
    F/A-18E: 6,780 kg
    EF-2000: 4,996 kg
    MIG-35: 4,800 kg
    Rafale C: 4,700 kg
    Gripen NG: 3,500 kg
    F-16 IN: 3,160 kg

    A2A Combat Taking-off Weight (fuel for 2,000 km ferry range according to Mr.Sign’s data+ 6 MRAAM and 2 SRAAM):
    F/A-18E: 21,700 kg
    MIG-35: 18,300 kg
    EF-2000: 16,350 kg
    Rafale C: 15,675 kg
    F-16 IN: 14,950 kg
    Gripen NG: 11,200 kg

    Sea-level Static Thrust, AB and Max Mil:
    F/A-18E: 9,980 kg*2 / 6,395 kg*2 (F414-GE-400*2)
    EF-2000: 9,185 kg*2 / 6,125 kg*2 (EJ-200*2)
    MIG-35: 9,000 kg*2 / 5,400 kg*2 (RD-33MK*2)
    Rafale C: 7,650 kg*2 / 5,100 kg*2 (M88-2*2)
    F-16 IN: 14,740 kg*1 / 8,620 kg*1 (F110-GE-132*1)
    Gripen NG: 9,980 kg*1 / 6,395 kg*1 (F414G*1)

    Sea-level A2A Combat Taking-off T/W ratio, AB and Max Mil:
    EF-2000: 1.124 / 0.749
    F-16 IN: 0.986 / 0.577
    MIG-35: 0.984 / 0.590
    Rafale C: 0.976 / 0.651
    F/A-18E: 0.920 / 0.589
    Gripen NG: 0.891 / 0.570

    well, i dont think rafale is underpowered, only if you compare it to EF, and you should compare the A/C for a similar mission, otherwise its not apples and apples.
    All A/C have its ups and downs, EF has its speed and TWR. Rafale has its EW, sensorfusion and strike ability etc.
    Still TWR isnt everything, for example, Close-coupled canard bleeds much less energy in turns which favor Rafale and Gripen.

    But it seems like rafale to have a too high fuelconsumption for western tech, i could agree on that..still its a looong way to F-35 and MIG-35 in this field 🙂

    I don’t remember having read this 2100Km on internal fuel. And you don’t know the mission profile type either and surely SAAB numbers are quite optimistic as reported by pepe Rezende who had access to the FAB evaluation. So really these type of comparison are leading nowhere. Especially internal fuel comparison as a combat aircraft is meant to be loaded. An when an aircraft is being armed the bigger aircraft will have an advantage in terms of retained performance.

    So you are saying offical sources on Saab is wrong??! i think they knows best..Pepe is a baised reporter with small knowledge of the gripen system. Gripen with one EFT goes 3500km(450gal) 😉 that tells you allot of the low fuelburn and also goes hand in hand with the low LCC figures of the gripen system.
    In this stage the Demo A/C has verfied the range data on internal fuel.

    [QUOTE=eagle1;1730595]

    So if we talk about pure kinetic aircraft performances, I will tell you that a rafale can carry more, futher while being the most maneuverable aircraft of the competition. After all it manage to toast Typhoon 8-1 in pure gun dogfight, repeatedly dominate the F16 in various exercises, crush the gripen as well in 2007 without forgetting the SH vs rafale M encounters. It even old its own against the mighty F22 (dogfights). I don’t think that any other aircraft of the MMRCA competition has such a proven record.

    [QUOTE]
    any source on the gripen domination? then only one i heard was a french pilot interview about dogfight high alt, and “Rafale have better sustained turnrate especially at high alt” not “domination”. Also remember its Gripen C/D we are comparing with..

    May we know your source for the Rafale ferry range?

    and for the other?

    Nic

    Nic, I have seen lots of sources telling me 2100km on internal fuel.
    Gripen NG 2500km (official sources)
    EF 2600km(internet)
    F-16 1750km is a very questional single source (which i dont remember), and somebody hopefully have a better one..

    Correct me if im wrong..

    With an AAM load, Rafale, EF2000 and Gripen NG all have about the same fuel fraction and engines with similar SFC.

    There is no reason they’d have vastly different ranges.

    Gripen and EF goes 20% longer in ferry ranges than rafale, i think its significant.
    EF and Gripen goes almost 50% longer in ferry range than f-16. Its significant.

    Sea-level A2A Combat Taking-off T/W ratio, AB and Max Mil:
    EF-2000: 1.046 / 0.697
    F-16 IN: 1.016 / 0.594
    MIG-35: 0.984 / 0.590
    Rafale C: 0.968 / 0.646
    F/A-18E: 0.879 / 0.563
    Gripen NG: 0.839 / 0.537

    EF goes 2600km with specifide fuel amount.
    Gripen NG goes 2500km
    F-18 goes 2346km?
    Rafale 2100km
    Mig-35 2000km
    F-16 1750km?

    Fair comparison??

    Rafale has some US components. They’re trivial, the only significant ones being in the datalink – and AFAIK India isn’t buying the datalink.

    Typhoon has the same datalink, & therefore shares US components with Rafale :diablo:

    those parts arent trivial, otherwise they wouldn´t be there in the first place…

    Sweden magical aerospace industry : the more complex the plane, the less expensive it is.

    If they had developed an F-22, it would have cost the price of a piper club :p

    yes its exactly like that..
    The less you have, the more innovative you get 😉
    The more complex, the more you should buy OTS to keep costs down.

    Systems like RM12 is very expensive, F414 is much less..
    To develop a new radar for only gripen jets from scratch isnt cheap, to develop it together with selex and other platforms on the base of dubble the amount of earlier development programs/expertise is cheaper.
    the list goes on..
    if there are hardware in the international market that fit the requirement why develop again?
    more money left for development of the things that really needs some heavy development.
    And there you have it. More for less.

    This is the way Saab works, its cheaper and less risky. But still there are critics of this way of integration. Yes it isnt all swedish, french, brittish or american, its a mix and international and cheaper.

    F-22 is a very bad examble of political steering and destruction of a program with superspecialized hardware led to a superexpensive jet.

    Unit cost was going back up at the time the program was terminated. I think it was a bad idea to cut the program at <250 units, but let’s not kid ourselves: it’s an expensive aircraft.

    But a B-version can be cheaper…the same things that goes into the F-15 can go into the F-22 frame…
    I just cant see why f-15 frame can be better then a F-22 “light”.

    wouldnt it be better to make a cheap version of the f-22 frame?
    cheaper RAM, incorp. a “lighter” F35 avionics, no or cheaper thustvectoring etc.

    This will also be what f-22 should have been in numbers..

    F-15 in general is still extremly old platform and isnt a step forward…Silent Eagle exist only because F-22 didnt become bigger in numbers, exportrestricted and expensive..

    To have some sort of air policing/QRA capability requires at least 20 front line aircraft. Keeping the bare minimum of two birds ready to go 24/7 means that there are going to be a number of aircraft dedicated to training. Maintenance and attrition also need to be accounted for. Anything less than this is not a real capability IMHO.

    Cuba, Serbia, Croatia, Baltic states and any number of other smaller nationds are all kind of in the same boat here. If the decision is to go for the bare minimum capability then there are a number of options that might be affordable/politically acceptable.

    • JF-17/FC-1
    • Tejas
    • Super Tucano/ALX
    • Used JAS-39A Gripens (the Swedes have mothballed a bunch of them)
    • T-50

    i dont think US will grant any export of F404 derivate or f414´s that leaves JF-17/FC-1?

    I believe he’s talking about the overall package price, not individual aircraft price and as the Super Hornet package price includes a large weapon, sensor and support package, but it is unclear if the other proposals do or whether these would be an additional cost, the prices are hardly worth being used to ‘prove any sort of point’.

    Unless it is an apples to apples contest with similar overall packages, quoting a price is futile.

    like to see a source thou..
    i´m kind of sceptic to such a claim to be polite..

    brazilian prices shows rafale at same gripen price, lower than the upgraded F18

    any source? Never heared anything like it..
