  1. Had my Viggen get blown up by an SA-3 the wing dissapeared but the U22/A was still in the same position relative to the wingless hull as it had been when the wings where there. But now it was hanging in midair !

  2. Has anyone tried using this in VR with a HOTAS as well? The extra joystick screams AJS-37 Radar stick to me, especially with the ability to map the additional buttons for similar functions.

     

    However I feel like controller makers are starting to lose the VR market - and I am torn between jumping into VR but then having to utilize complex button HOTAS only arrangements or sticking to TrackIR and utilizing tools like this and advanced HOTAS units with extra switches to essentially have appropriate commands to unique and easy to know positions.

     

    The joystick has two modes.

    Press one of the buttons on top and it will turn into a "different" joystick that you can map to something else.

    Like switching between radar stick and RB-05 stick !

  3. Would love a Draken!

     

    The problem with a JA 37 is the datalink and some other systems that are still classified. (JAS 39)

     

    The problem with the Draken is that it never got any good missiles....

     

    I wonder how classified. The national ground to air datalink was retired when the JAS-39A/B was retired. Later Gripen versions use the Link 16.

    The link between the Viggens is most likley not the same as in the Gripens either as it's from the early 80's.

     

    The U95 ECM pod is probably classified but we know a few things about it which is probably enough for the limited ECM simulation in DCS.

    The Radar of the Viggen is out of use and soon the Swedish air force weill be using nothing but AESA radars in their Gripen fleet so even the technology it's based on will be obsolete.

    The AIM-120B is in game and the Skyflash is out of service.

    The AIM-9L is well known as is the AIM-9P3 and the Oerlikon gun.

     

    I think there's enough info that could be handed out for them to make a module. There's no need for them to know the intricacies of things like data-links either just what information it sent and how it was displayed would be enough.

     

    In fact DCS there's basically a datalink to all aircraft and to the GCI map. If you see something on your radar it shows up on the map. That's a function the Viggen got in the 1980's.

     

     

    But either a Draken module or a Ja-37 Viggen module would be great.

    Howeveri would like to see two draken versions as well the Danish F-35 and the J35J or the finnish J35XS which was upgraded to J35J but also got an RWR and Chaff/Flare dispensers.

  4. The RB75T hade a mine warhead for use against ships according to the blogger/twitter "Wiseman" who's an actual Gripen pilot so he should know.

    The Warhead was developed in Sweden for that purpose.

     

    This isn't the first time Sweden modifies weapons it buys. When it bought the Hellfire for the coastal artillery as a man portable light anti ship missile they changed the warheads on those missiles too. The system is called the RBS 17 in Sweden.

     

    The Lansen era bombs where old 1940's designs for the most part, i think the illumination bombs where the only carryovers.

     

    The reason I've read is that the Viggen was so expensive to develop there where never enough money to give it a well rounded armament.

    For instance a heavy smart weapon was on the wishlist for it's entire career but never materialized (called TSA in swedish "Tungt Styrt Attackvapen").

     

    But since so few Strike Viggens could be afforded this partially solved itself as the requirement to support the army in northern Sweden was stricken because of the low numbers. There where only enough Viggens to defend against a naval invasion.

     

    As a stop gap a light attack variant of the SAAB 105 trainer called SK60B or C was procured and they inherited some of the Lansen's weapons chiefly the rockets. The Sk60 had weak engines and didn't like asymmetric loads otherwise it would definitely have gotten the RB-05 missile, and i suspect some of the Lansen's old bombs as these aircraft would operate in northern Sweden.

     

     

    FYI: The A32A Lansen's 500kg m/56 bomb is a regular British 1000lb bomb btw, i haven't seen specifics on what version it was but i think it was the ww2 1000lb MC which was extremely common in ww2.

  5. I dont think the RBS 15G was actually developed though.

    It was just a variant that was planned / considered but never actually built.

    (and Sweden did not get the GBU-15 either).

     

     

    And the picture you linked seems to be just Showing a normal RB 15F

    (With a RB75 on the outboard station) being carried by a JAS 39 Gripen.

     

     

    There were multiple ideas / plans for weapons / airplanes etc considered / written about in the 1970s and 1980s that were not fully developed

    (Saab A20, Saab A38/B3LA in the case of aircraft and RB 72, RB 73 and RB 82 as examples Missiles just to name a few)

     

     

    So the RB 15G was just one amongst all of those proposals that was never fully developed / adopted but instead canceled early on.

     

    The Viggen never got a Heavy Guided Attack Weapon, it was always in the studies but the money for it was never there.

    In many ways the Strike Viggen never reached it's full potential because money was always very short. And with the JAS Gripen a replacement was in the pipes for half of it's career.

  6. No it's the Viggen's Avionics that's limiting the range, it simply can't give the proper instructions for a long range stand off drop.

     

    The BK90 has been test dropped from much farther away at high level, i think the 500 meter altitude ceiling is from the Viggen radar altimeter.

    I think the BK90 can fly 22km if dropped from 6000m, but as i wrote the Viggen can't handle that.

     

    That the BK90 can be carried at all is due to the 1553 weapons bus being part of the AJS upgrade

  7. Locking air targets has worked for me at least when i've selected guns or sidewinders.

    One has to be fairly close and then put the radar in lock on mode, the radar will go black and you'll see a distance line on the hud indicating if you are in range for weapons release or not.

    For those who can read Swedish.

    A technician Göran Hawée describes the Hawée 1&2 mods that where applied to the draken in the 80's.

     

    Hawée 1:

    It was a modification of the radar to make it much less ECM resistant and as a byproduct the radar became much better at low altitude.

    The Radar also became more user friendly to operate.

     

    Hawée 2:

    As a result of the new low altitude performance the AIM26B missile was now setting the limit for low altitude engagements as it's proximity fuze had a tendency to detonate below 500m.

     

    So the missile was modified with a new proximity fuze and the Draken got a limited HOTAS setup where you could arm missiles and switch between weapons more easilly.

    The Radar was also modified to be better at locking up targets at low altitude.

  9.  

    In the 1980's one Draken Squadron had a musical band and where quite active in PR work to keep a strong Figther Pressence around stockholm.

     

    Adam Gul = Alpha Yellow = F1 Wing Third Squadron

    Petter Röd = Papa Red = F16 Wing First Squadron.

     

    It was the same squadron and was based at the olf F18 base at Tullinge however it was administered from F1 and when that closed from F16. The Sqiadron was disbanded in 1985 and in 1986 F16 started converting to a Viggen Wing which left F10 as the last Draken Wing in Sweden.

  10. This is very interesting. Do you know how extensive the required modification was? Was this something which could have been applied to the AJ 37 in wartime*? Was this something the Swedish Air Force planned to do?

     

     

    *Leading up to the Falklands war, the RAF bolted Sidewinders to Nimrod maritime patrol aircraft in a matter of days.

     

    A Sidewinder is extremely easy to install any maintenance crew can probably do it in a few hours as long as they have a pylon to work with !

    Also for comparison the fighter version has been reinforced structurally and is actually heavier and that thing carried Rb-74's on the outer pylons all the time.

     

    Something the air force could have done though is use the H7 pylons which was completely unused on the AJS series and only carried dispensers on the JA-37 after and upgrade late in its career.

    Those pylons where rated to 500kg and could easilly have carried say Mk83 bombs if Sweden had used them at the time. That way the two pylons on either side of the drop tank could have used Sidewinders.

  11. Jamming and burnthrough in DCS is unfortunately quite simplistic and we can't really do much about this. For the most part, it's just a multiplier to the ranges of affected radars.

     

    Is there a different modifier between the different systems, from what i've deduced the U22 & U22A is devastating to older non-monopulse radar like the ZSU SA-3 etc which it can totally mislead.

    With monopulse radars like the SA-8 and newer the best it can do is create a bunch of jamming pulses and hope the radar crews don't figure out which one is the aircraft.

  12. Well the outer wing pylons where seriously limited when it came to loading.

    Even carrying Sidewinders there during normal flight seriously limited the airframe life of the Viggen.

    It could be that the heavier cooling assembly fore the RB74 was simply too heavy.

    Or it could have been too complicated to install.

  13. I pressed the quick select IR missile button while i had RB05 selected.

    It seemed to Switch to Sidewinders as the Radar changed mode and i heard the growl.

    However i still launched the RB05 missiles and then the sidewinders when i pressed the trigger.

     

    I had done the same things when carrying other weapons without this behavior
