    Interesting. I’m sure you have references to back up that statement…and will show them to us.

    Most books I recall reading said the pilots hated the radar sight. I did a quick check on the internet and founding conflicting opinions. This one page I found here:
    http://scilib.narod.ru/Avia/Sabre_vs_MiG/index.html
    (you have to scroll down in the index to the armament section and click the paragraph link where says “The A1-CM Radar Ranging Gunsight”)

    This page said that it had problems and some pilots liked it, some didnt.

    The F-5 flight envelope is smaller than the F-104’s. In a low altitude hard turn, the F-5 bleeds speed much faster than a F-104 when maneuvering above 400KIAS.

    Lets be honest, a jet does not hardly maneuver at 400 kts, certainly you could not describe the kind of turn you would do at 400 kts as a “hard turn” in any kind of jet, g-force being the limiting factor keeping jets at large sweeping arcs of direction change.

    You failed to explain how the Draken is more versatile than the F-104. Versatile does not mean ‘maneuverable’…in our context, it means having more uses. Are you prepared to defend the opinion that a Draken has a greater number of uses than a F-104?

    Please explain how the F-5 is “far superior” to the F-104 in “maneuver and load carrying”.

    Comparing fighters is kind of a fun game because there is no absolutes, designers go to opposite extremes and still come out with solutions that match fighters at other extremes. I think most people would agree that the F-104 concept of relying on a small wing and powerful engine did not work. Its a fighter that cannot maneuver or carry a decent load for its size. The fact that a fighter like the F-5 can perform better in every regard with engines a small fraction of the size would show that the F-104 is buying you nothing but speed, and false speed at that as it was shown that these small wings do not give untouchable low level speed but rather are easy meat for subsonic fighters like the mig-15 as shown in Vietnam. The F-104 was overwhelmingly bad in every respect and sold well as it was the only major mach 2 fighter sold at the time

    :confused: Lightning had the same engine as Draken – but two, instead of one. MiG-21 had a smaller & less powerful engine.

    If you want to talk about thrust to weight ratio, then there’s less difference, but in absolute terms, there are huge differences in power.

    The F-15 has the same engine as the F-16 – but two, instead of one. The Eurofighter has a smaller & less powerful engine.

    So does that mean that the F-15, F-16 and Eurofighter are not in the same class? I dont think so.

    The F-86 had a ranging radar assisted gun-sight coupled with weapons of higher firing speed. All that gives a greater hit propability from the start and is not debatable. 😉

    The radar ranging gunsight was worthless and ignored by pilots who instead used the “gum sight”, a piece of gum stuck to the inside of the windscreen to serve as a target redicule.

    You’ve completely misread what TooCool said, & turned it round.

    whoops, my mistake, I mis-read mig-15 for F-86, sorry, my brain has been sort of burned out lately

    So you have no problem to bolster your claim about the Draken with some data about inst/sust turning capability for some height and speed values for the benefit of all readers.

    All I can tell you is that the engine intakes served as wing area and provided turning leverage forward of the CoL, which among other things, allowed it to pull off the cobra maneuver.Im not trying to make it out as a wonderfighter, Im sure it bled a lot of speed in a turn. But Im sure its sustained turn rate was much better than the Mirage3/5, although I have no hard data on that.

    Did you red the listing of fighters and subsonic agility without the F-104 to stay polite?! 😉

    OK, I guess seeing the Mirage in that list made me over-react. I would agree that the Draken, Lightning and mig-21 are roughly in the same class of fighter in power and maneuverability. But the Mirage3/5 is really an awful in maneuverability and is in no way comparable to the Draken. I dont mind comparing dissimilar fighters, but when people lump fighters like the Mirage, F-104 and Draken together in the same class, I find it very insulting to an intelligent discussion.

    You maintain that the Draken was a more versatile aircraft than the F-104.

    In what ways?

    The Draken is extremely maneuverable (A0A-wise) for a non-FBW delta wing fighter, whereas most other tailless deltas like the Mirage3/5 just bleed airspeed in a turn. Its a night and day comparison to the F-104 which does nothing but go fast. Even an F-5 is a far superior fighter to the F-104 in maneuver and load carrying.

    * the Mig-15 had the advantage on four points over the sabre:

    – it could climb a little better
    – it could turn slightly tighter, especially at slow speeds
    – it could reach a higher ceiling
    – it had more punch with its canons… when they hit

    Im quite sure you are wrong about the F-86 having better climb and turn rate. If that were true, F-86 pilots would not have had to employ tactics that favored the more obscure advantages that the F-86 held, almost identical to the tactics that Hellcat pilots used in WW2 against the zero. I strongly disagree that 6 .50 cal guns have more punch than 2 23mm and 1 37 cannon. How much the greater hit probability factors in is debatable.

    Yeah … when they get them all, one hell of an Airforce with the whole 154 F-15S/SA( old ones to be modernized), the (87?) Tornado IDS GR4-like, and the at least 72 Typhoons.:rolleyes:

    I read in the news that Saudi Arabia is going on a huge military spending spree to expand the size of it military to become a regional power that will counter any threat by Iran and fill the void left by Iraq. We could see the Saudi AF becoming much larger than what current acquisitions would indicate

    The Draken, Mirage, Lightning and MiG-21 had similar subsonic agility capabilities

    you have no idea what youre talking about

    When it comes to versatility the Draken had the edge over the F-104.

    to say the least

    The F-104 should never have entered service, it was designed in the early 50s in response to the F-86 being inferior to the mig-15 in the Korean war. Im sure the tiny wing/large engine concept seemed like a great idea at the time, but as it turned out speed, engine power and missiles did not make dogfighting obsolete and the vietnam war proved that the concept did not work as F-4s, F-104s and F-105s were all humbled by the more maneuverable mig-15, mig-17 and mig-19. The F-104 was extremely aggressively marketed (forced down the throat of allies) so that superior options like the F-8 and Grumman Tiger did not sell like they should have.

    The Draken was very far ahead of its time with AoA capability unlike any other non-FBW fighter of its time. The Viggen followed the layout of high thrust to weight ratio coupled with large wing area which in the 60s gave it capability similar to that of 4th gen fighters like the F-16. It was slightly stiff, but had acceptable turning rate. Close in the Draken would have the edge.

    Top speed in itself is not necessarily of great importance, but the difference between M1.4-5 & M2.0, with about the same T/W ratio & basically the same engine, suggests that T-50 is much more draggy, which isn’t good for a fighter.

    going by the mach 1.6 top speed being draggy, I guess that would knock out the Typhoon and Hornet out of the competition

    Not “roughly equivalent to the Gripen” at all. T-50 is a trainer with a light attack version, & a fighter version under development. The EL/M-2032 radar (still being integrated, last I read) of the light fighter version may be equivalent in quality to the PS-05 of Gripen C/D, but is smaller & less powerful in the version fitted. Also, it’s Israeli. Would Malaysia want an Israeli radar? If not, it’d either have to put up with the APG-67v4, or wait for something better to be integrated. Even the fighter version lacks some of the other systems of the Gripen. With a slightly less powerful engine & similar T/W ratio, T-50 is significantly slower than the Gripen A/B/C/D.

    OK, so the Gripen does have better systems, that does not make it worth double the price. American equipment could be fitted. And as for being significantly slower, being mach 2 capable is pretty irrelevant nowadays. Mach 1.6 is a reasonable top speed for a lot of 4th gen fighters.

    What relevance does “companies like Naza do business in Korea” have? Many Malaysian companies do business in the UK, Germany, France, the USA, etc.

    oh of course, Malaysia does business with europe and the US, what relevance would there be for them to do any business with Korea, what was I thinking

    Malaysia is not going to buy enough of any type for it to make sense to build it under licence.

    I think Malaysia has only about 50 fighters in their inventory, they are mostly expensive fighters. A cheaper fighter could open the way for a larger purchase

    What would be the chances of Malaysia buying the Korean T-50 be considering companies like Naza do business in Korea? The T-50 is roughly equivalent to the Gripen, but a lot cheaper. Perhaps Malaysia could build it under license.

    Also it would be nice to see the french offer the M2K as a low cost alternative to the Rafale in this competition

    In my opinion one of the best platforms suited for CAS would be upgraded skyhawks, with a simple non afterburning version of the F404 or 414? to reduce cost and complexity. And it’s even carrier capable

    If you look at the specs of the Skyhawk, they are exactly identical to the AMX. The advantage of the AMX is that it has a radome in the nose whereas the Skyhawk is not able to carry anything in its nose but rather on a hump on its back.

    But in my opinion, the F-5 is the best bet for an old fighter to put back into production. Its still used as a front line fighter by first rate airforces all over the world (Korea, Saudi Arabia, Turkey, etc). And it has pretty decent load carrying ability. The cost of fighters is too high for most governments to justify buying, even a K-8 trainer costs $10 million USD. It really surprises me no one has built this fighter under license. The other fighter that has a good shot at being made again is the Jaguar, I wonder if it would be possible for India to build and sell them.

    you guys are forgetting about twin engined fighters, how about a turboprop Mosquito or Ta-154? The Ju-88 when fitted with BMW radials showed incredible low level speed. In fact the Ju-88 was originally designed to be able to use as a dive bomber.
