    here’s an interesting point, on the F-5 vs the F-16
    http://www.f-16.net/forum/viewtopic.php?t=6082

    it seems upgraded F-5s do have advanced radars, DASH and the latest missiles
    which I’m guessing means they can at least match current USAF F-16s one on one at BVR, and are actually superior WVR with helmet cueing and Python missiles
    here’s a Thai F-5 with said upgrades

    However, previous generation aircraft just were not designed to have all that stuff which is today seen as necessary equipment for a fighter. You can’t install DAS to an F-16, much less MiG-21, there is no room. New requirements keep coming up, this means new systems, new sensors, new equipment, better performance -> volume and weight requirements go up, and you need a larger plane.

    interesting point, but why can’t you install DAS on an F-16? from what I can tell it’s just a number of small camera’s. if anything it’ll be much easier to install on an older aircraft, because you have no worry about stealth

    Nearly everything has to be carried externally as there is no room inside the aircraft

    which is one of my biggest beefs with stealth aircraft, they have extremely limited room for new stuff
    for example we can assume that lasers will become a deciding factor in future air combat. let’s assume for a moment that they make missiles and cannons pretty much obsolete
    but what if the size of the laser is an essential factor, that decides power and range?
    in that case stealth aircraft would be at a big disatvantage, their laser would be limited by their need for stealth. like the Super, maybe they’ll only be able to carry it outboard, reducing their stealth
    you might be able to put it in a stealth pod, but you see my point: the nature of stealth aircraft greatly reduces their ability to integrate new technology

    so the pilot has a thigh-mounted mini-display for maps and other essential information.

    which is a very effective and innovative way of integrating new tech onto an old aircraft. you install something new and useful wherever you find the room
    it’s the same thing with guns for example: put a new scope onto a 50 year old design like the M-14, and you’ve got a weapon that can match the best
    sure the newer models are lighter, have a silencer, adaptable to lefties… but this way you get 90% capability for the price of the scope, rather than buying a whole new weapon
    which might have the newest scope integrated, but this will become a limitation as scopes evolve. good example of this is the Steyr Aug rifle, which came with built in scope, but this means at one point it becomes outdated

    With today’s WVR dogfight missiles and HMS, everybody dies in the furball.

    agreed, which is why I’m a big fan of unmanned fighter UCAVs, at least for that initial WVR identification
    fast and cheap, they’d be little more than a big missile
    or you can take an actual missile, explosives optional, and send it to the target so you can get a visual ID. I imagine modern data-linked missiles with optical sensors like the AIM-9X can already do this
    if you make it reusable (parachute, or even re-atach to the launch aircraft), it becomes a relatively cheap way of avoiding a dogfight

    For 99.9% of air policing tasks, a high end business jet from Gulfstream, Bombardier or Falcon fitted with an IRST pod would perform quite well and be substantially cheaper to purchase and support than a fighter.

    again, then you might as well go for a UAV, it’s even cheap, with better endurance and no pilot at risk

    At the same time you get much higher processing power from a smaller volume.. LED displays are much lighter and thinner than CRTs… modern radios and GPS receivers are a fraction of the size and weight of their predecessors..

    exactly, the F-22 is already outdated in many ways, how long before the F-35 is?

    Sanem, you would upgrade your F-16 so much that they would look like an F-16 block 70 which would cost a lot. If your goal is to confront a plane like a PAK-FA, it would be very cost effective I think to add 50-66% to the cost and get a stealthy F-35.

    ah but then you’re talking about buying the brand new block 70 F-16, which will cost you 70 million. then an F-35 is probably better
    I’m thinking more along the lines of upgrading warehouse F-16As to block 90 if you will. then for maybe $20 million you get F-35 level abilities and more (if you use more recent tech, considering the F-35 tech is already 10 years old)

    Sure thing, you can make big improvement over old equipment. But a whole new aircraft remains more capable.

    and a lot more expensive
    I mean if you could choose between an F-35, or a 50 year old F-5 upgraded with the latest technology, their technological level will not be that different (other than stealth) but the F-5 would be a fraction of the price

    if you read about geopolitics, the US has a long history of trying to divide the EU, by turning the member states against each other. divide and conquer
    the same principle likely applies to the European defence, a lot of EU countries are now buying American UAVs, which means money and a large degree of US control over Europe’s defence
    it’s probable that the US is using the UK to delay the European UCAV project, as it would compete with both American industrial interests and the F-35
    “sure you can buy the F-35, if you don’t mind asking the Pentagon’s permission everytime you take it out of the box. or you can buy a European UCAV, at 30% of the cost, with full control and better range”

    UCAVs could have been operational by now (J-UCAS and the RQ-170 prove that), which would have been more effective and efficient, and resulted in a less dependant Europe, but then some people would have made a lot less money

    a little something for @Sanem

    ha, interesting 😉
    for one hour of F-35 you can get over a 100 hours of Predator

    I wonder where turbofans fit in that list?
    for example the Avenger has a PW500 which has a lb/h of 0.44, whatever that means

    on a different note, any thoughts of the possibility of Israel having UCAVs?
    here’s an article from 2012, stating that IAI which builds Heron and Eitan has been working on stealth since the 1990’s
    http://www.flightglobal.com/news/articles/israel-working-on-low-observable-uav-379564/

    seeing how Israel has been a front runner in UAV tech and has little of the USAF’s bias towards UAVs, it would be a logical step, both for intel and attack missions
    with rapid prototyping and 3D printing, it’s be very easy and cheap to develop, and a huge force multiplier

    The only reason for such a buy would be to ensure that ONLY US could undertake the mission you mentioned above.

    ah good point but
    a) I don’t thinkIsrael would actually attack Iran, that’d be extremely risky, if only because it’s such a long flight
    b) even 150 J-10s or S-400 would be of limited use against Israel, because they would counter them some way or another
    for example how Israel started using UAVs back in the 70’s to defeat its enemies’ advanced defences
    in the same way Israel could use a number of unconventional strategies and tactics if it did want to attack Iran. contrary to the US, which mainly relies on traditional and thus predictable tactics and assets
    except maybe UCAVs, but who’s to say Israel doesn’t have those as well? they are the world’s foremost UAV builder, and stealth technology can’t be very hard for them to develop or copy from others

    edit: discussion on Israeli stealth UCAVs, something I disagreed with at the time :p
    http://aviationintel.com/israel-developing-a-stealth-ucav/

    edit2: thinking some more about it, a stealthy UCAV would allow Israel to attack Iran effectively, as it has range, expendability and a relatively low cost
    and would make J-10s pretty much useless

    Taiwan’s version of Predator drone.

    that is so cool
    I guess (not) buying from the US for so long has thought them to build it themselves

    nice find, but can’t see it either
    no smoke without fire, so I’m guessing they wanted to post about it and then changed their mind (for whatever reason)

    an important factor for autonomous air combat is computer aircraft recognition

    here’s a pdf article on ISR image recognition from 2012

    I am aware of quite a number of prototypes, all related to the programs that i´ve listed above, but the dam thing is that no one in the industry (be that Boeing, Northrop, LM, GA, BAE, Dassault, Piaggio, Selex, IAI, whoever) is going to develop a highly advanced combat system without some MOD footing the bill, and the Finnish MOD doesn’t have the kind of budget to pay that bill.

    oh absolutely, but as you suggest UCAV development has nothing to do with the technological possibilities, and everything with military/political choices and budgets
    there’s a pretty good chance the USAF does have UCAVs in its black ops inventory, armed MQ-170s if you will, kind of like unmanned F-117s
    it’s not for sale, but it can and should be
    buying anything else in serious numbers at this point is a waste of money

    that said, it’s a matter of time before they become available
    as companies put work into UAVs, they can use the software and hardware on pretty much any platform, be it a slow prop recon UAV or a stealthy jet armed UCAV. the sensors, computers and flight/mission algortims are mostly the same, regardless of size or design
    and new techniques like 3D printing are greatly reducing production cost, time and needed investments. one machine can print manned jet or UAV parts equally well
    meaning in the near future, there could very well be an explosion in UAV and UCAV systems offered, the way we see it happening in the civilian UAV sector, as the price for such systems comes down and its capabilities become ever more useful

    Being very optimistic a “Neuron offspring” (its called “FCAS”) will be available for evaluations circa +2030. Its entirely irrealistic to expect the Finnish air force to seriously look at hardware that will only be available in the mid thirties. This is a straight toss between the F-35A and the Gripen, any unmanned component looked at will be a recon/ISTAR platform with (maybe) a bit of (very) light attack added, think Predator or a Israeli solution (on a stretch the Italians might offer something) in very small numbers to add to a manned combat jet fleet.

    talk about bogus
    the X-45A succesfully executed an autonomous training mission in 2005
    BAe suggested it made great progress with the Mantis and Taranis programs
    NG, Boeing, LMT and GA all say they can have UCAVs ready before 2020
    the technology is there. there’s no reason it would take another 15 years to get FCAS ready, other than to keep it from competing with the F-35

    that said, Finland doesn’t have the money and won’t have the money for (many) fancy new jet fighters
    my guess is they’ll keep going with the F-18, and add UAVs and UCAVs as the market matures
