DCS: AJS-37 Viggen Discussion

Inställn is shorthand for "inställning" = setting. Klaff = flap (in aeronautical context).

 

Ah kay, could have thought of that one myself.

Setting is Einstellung in german and flap is more or less Klappe, Landeklappe tbh exact in case of landingflaps. Airbreak would be Bremsklappe [breaking klaff :D]

 

Not a bad guess, but not right either. The switch says "1:A VAL RB05/75, RB 15, BK". 1:a val is short for "första val" = first choice (compare English "1st"). V and H are short for vänster and höger = left and right respectively. It determines which weapon is fired first, so that's why you see it set to H in case of asymmetric loadouts with something else on the left pylon. The "default" setting is V.

 

Also, weapon options in parantheses indicate you can choose yourself if you want to fill that station or not - no extra preflight button pressing necessary.

 

Ah yee, that makes sense. Thx !! :)

I heard another story about a J35 from F4 returning to base after having reported a bird strike. When the mechanics looked at the damages they found needles from a spruce tree so they confronted the pilot and questioned his bird strike report. He replied "So what? I can't help that the @$#o@#% bird was sitting in the top of a tree, can I?"

 

Great, just got coffee up my nostrils -_-

 

:D

I think this bit of weirdness is a result of the way they upgraded the computers and interfaces - or rather how they didn't upgrade the old interfaces. Rb 75 is one of the original weapon systems from before the upgrade and uses the old (most likely analog) interfaces made with vacuum tubes and wizardry - that is to say, it can't really "talk" to the computer. The rb 15 and bk 90 are new, post-upgrade weapons which talk to the computer using this wonder of modern technology called a serial bus - kinda like the one you might have used to plug your 14.4k modem into your computer back in the 90's (internally the computer actually uses RS232, but to talk to weapons it's the serious business NATO compatible MIL-STD-1553B). Just put them on a bus-enabled station (so any of the S7 and V7 ones) and it'll self-identify to the computer and they can figure out together on which weapon station it is and if it's working properly etc etc.

 

Combining new weapons is (and now I'm speculating) probably not an issue as far as the computer goes, you just put them there and the computer will figure out what's there and how to fire it. The problem is that the old weapon selector switch combines all the modern weapons into one choice (04/15/BK).

 

Yee collecting old industrial/in general critical application computers here. VAX and Alpha systems from DEC running OpenVMS mostly. That stuff the murricans used to run there ICBM launch sites and the russians copied for exactly same purpose. Which lead to this anecdote of the cold war:

https://micro.magnet.fsu.edu/creatures/pages/russians.html

"VAX - when you care enough to steal the very best "

So I pretty much know what kind of interfaces there is. :D

 

Hmm, dunno if the interface to the 75s is really analog, which is pretty probable, I mean its just a TV image, a seeker position and a few signals the connection would have to provide, there should be no problem to have it on one of the bus stations, as long as the analog and digital systems can work at the same time. Or to be more exact, independant of each other, or if they only have exclusive access to an HUD interface etc..

Fun fact, AIM9x was the first AIM9 to feature digital interface to the plane, has an analog fall back still, but still interesting for how long the analog interface was kept.

So the question for the AJS37 is really, if the AIM9s are handled by the same firing Computer like 04/05 and 75 would be. Which I somehow doubt, which would explain why it can load old aim9s while it cant load 75s if digital interfaced Weapons are on board.

Any confirmation on whether we will get the Mk III version of the RBS-15 that was land target capable, or will we receive the anti ship only version?

Rbs 15 Mk III didn't start production until 2004 so there's really no reason to include it AFAIK.

 

Also, Wikipedia says this about the mk III: "There is only a ship launched version."

RBS 15 Mk. III is ship launched only. Air force still uses (a variant of the) Mk. II even to this day.

Edited July 20, 2016 by Skjold

[microvax]

RBS15F is the one we get, was the only one carried on the AJS37.

 

We would need an JAS39 to launch RBS15F ER.

 

EDIT:English Wiki says there is an MK. III which is airlaunched, named RBS15F ER, but that is proabbly not even in service I guess.

EDIT2:[ame]http://saab.com/globalassets/commercial/air/weapon-systems/air-to-surface-missile-systems/rbs15f/rbs15_missile_system_family_high.pdf[/ame]

SAAB says its in service with the swedes.

Ah, I see- anti ship only, then!

[Skjold]

And yes - realistic loadouts is preferred. Any non-realistic ones should be optional.

The RBS-15 Mk III can be launched from ground vehicles as well...

Since there has been so many variants perhaps some clarification is in order:

 

First version was RB-15 M1/M2 which was adopted on the Norrköping class vessels (former Spica II class torpedo boats). Then the airforce got their version RB-15F (which is the one we will see in DCS). Next Kustartilleriet (today the Amphibious Corps) got the RB-15 KA. There has also been some special export versions like the "SF" (for Finland) and "B" that was exported to former Yugoslavia. The Mk II variant was initially supplied to the Navy, and again to the Norrköping class vessels when they underwent a modernisation in the 1990's. The Mk III is ordered by the Swedish armed forces (and Germany if I'm not mistaken) and there is even a Mk IV I think. But the airforce is still using the 15F...

 

Speaking of the Norrköping class vessels. They almost sounded like Viggens when "taking off"...

Thanks for the clarification Hadji, what i meant was that the the only planned operators of the Mk III is naval. You are correct, they are planned to be used on the Braunschweig class amongst others in the German Navy.

[renhanxue]

The Norrköping/Ystad class look amazing and sound amazing. That long, low hull makes them look even faster than they are, and the acceleration is unreal. They were never the biggest or the most powerful ships but they were an icon of the Swedish Cold War navy. They are the closest you get to a Viggen on the sea and were designed for similar tactics - run out, shoot a lot of ASM's and/or torpedoes, run away.

 

Someone earlier in the thread mentioned a Viggen at the altitude of the bridge of his ship. This isn't quite that low, but it's a really cool air force/navy hi-five photo.

Not bad is someone can get that ship on DCS on the future.

I agree. Then we could test Swedish cold war defense tactics against any potential invader coming from the sea. :thumbup:

 

 

This is one of them, HMS Västervik, moored at Marinmuseum in Karlskrona.

 

Fun fact: In 1981 during the "Whisky on the rocks" incident, U137's captain Gustjin was interrogated on board the HMS Västervik.

(Västervik was still a torpedo boat back then but was converted to a missile boat in 1982.)

 

The sound they made (or make since HMS Ystad is operated by enthusiasts today) comes from the 3x Marine Proteus gas turbine engines. Each provding 4000+ HP...

Extra points for batmobile exhaust!

[Angelthunder]

A heads up Viggen fans.I just saw in my Combat Aircraft Magazine that it is going to publish an Glory Days article about the aircraft in next months August issue.

[MA_Goblin]

El Hadji, that's my old boat :) After that and the naval officers academy I went under the water instead :) See ya in I./ZG_Wespen mate ;)

[El Hadji]

The only boats I only saw from the inside during my service were the noisy and diesel smelling 200-boats fitted with wooden benches. Many people thought that the fast disembarking during amphibious landings happened because we were well trained. The truth is that we couldn't get out of those tin cans fast enough to get some fresh air after the bumpy ride...

[dartuil]

Time to show that viggen!! :)

F-5E is out!!

I think he meant that now that the F-5 is out we need a Lansen!

agree! time to relase AJS-37,

[scaflight]

Comparing Swedish fighters/strikers to NATO equivalents

Out of curiousity -- how do the Lansen and Draken, at their respective heights of service, compare to other aircraft? Can we make rough comparisons to F-86, Starfighter, Thunderchief or first F-4 when it comes to radar? The Viggen has a lot of unique whistles, not to mention firsts, but I've mentally placed it (or rather the several versions) approximately in the category of the F-16A.

I can't say for sure about the AJ and AJS but I know the last iterations of JA 37 (fighter variant) was said to be more technically advanced than the currently active JAS 39 GRIPENS (although that was the Gripen A at the time.) :-)
