DCS: AJS-37 Viggen Discussion

[zerO_crash]

!!!

 

I assumed the radar had no cursor. I imagine you could, after some experience, visually survey the area and figure out what it would look like on radar then put the cursor where the targets should be. But this violates the Viggen's 20 meter service ceiling.

 

Totally thought you'd have to use JTAC or the radar range scale to figure out an offset from your current position, then manually convert/enter the offset coordinates. Not to mention recalibrating the INS before dropping

 

You don`t recalibrate INS, you update it. And yes, there is a mention of a radar cursor.

 

Stick to facts, guessing doesn`t get you anywhere. Which is why the question to LN in the first place. Since BK-90 has a possibility to receive coordinates, it also means that without a GPS it also has a chance to drift. Yet another unknown.

DCS: AJS-37 Viggen Discussion

 

You can designate targets with the Bk90 in the Viggen in three ways:

1. Preloaded or in-flight inputted coordinates.

2. Radar cursor while radar is in active, passive or "snapshot"-mode

3. Overflying the target and marking it

 

You can't use the HUD unfortunately.

 

Edit: Neither Bk90 nor Viggen itself has GPS but Bk90 has INS which guides it to the coordinates relative to the launching aircrafts own indicated position. So any error in the indicated own position in the airplane will transfer to the glidebomb.

Thanks for the clarification, RagnarDa.

Golden, thx for chiming in :thumbup::thumbup::thumbup:

[mattebubben]

Thanks on the Update Ragnar.

 

Just another question.

 

Will you include multiple BK 90s for the different Submunition Options?.

(One Using MJ1s and one Using MJ2s for example)

 

Since i very much hope we get Both Submunition Options as they are very different in their performance / effect.

 

(The MJ1 Submunition is a 4Kg Air-Bursting Submunition for use against Soft targets where as the MJ2 Submunition is a 18Kg Anti-Tank Submunition)

[RagnarDa]

I did one MJ1-only mix, one MJ2-only mix and one 50/50 of either.

This is gonna be great! Awesome stuff :pilotfly:

[Sporg]

the AJS 37 might still be the first released module to have it.

 

But the A-4E showed it first =P.

 

Though it sadly does not really matter if one has worked on something for a long time and was the first to make it.

 

The first to display it to the public is usually the one who gets the credit =P not the one who discovered it first but only worked behind closed doors.

Well, if that's the criteria, ED's F/A-18 won by a long stretch:

But I guess they "won" so long time ago, that nobody remembers it anymore.. :D :D

 

Let me just say, I prefer to wait and see a module which is actually released with a functioning A-G radar. ;) :)

Sounds more and more interesting this module. :)

Yes i know about that Picture.

 

But a Video is allot different then a picture as it directly shows it working in game where as a picture (that is not even a part of a cockpit) does not tell people as much.

 

But either way its a Race right now between the A-4E the AJS 37 and the F/A-18C on who gets to the public first.

 

My hope is for the AJS 37.

Thanks for the Response and great news =).

 

That was pretty much exactly the options i was hoping for.

@RagnarDa, got some more questions:

 

- Based on what you once wrote about RB-15F, can one assume that RB-15F can be used like a long range A-G missile? Thinking here of how you can setup the waypoints for the missile. In short, can I give the missile coordinates to impact ground on a specific place I wish it to?

 

- As far as I gather, RB-75 (Maverick A derivative) was the only one used on Viggen. But due to display resolution limitations, you implemented the B version maverick version as it should fit and work just as the A does. My question is if the also included Maverick T version is IRL a possibility, or if you would need to modify the pylons/wiring.

The RBS 15F carried by the Viggen has no Air-Ground Functionality,

And you dont give it a impact point for Anti-ship work you tell it to fly to an area and search for targets using its oboard seeker once it gets to a certain spot.

 

The Latest RBS 15 variants the RBS 15 MK III (for Land/Ship based) and RBS-15F ER have Land attack Capabilities but im not sure how they work and im 100% sure that that capability is not present for the RBS 15F we are getting for the AJS 37.

 

And could you please clarify your Question about the Maverick =P.

 

By Maverick T do you mean the RB 75T

(with AGM-65 Seeker / Body but with a heavy 140Kg penetrating blast-fragmentation warhead much like some later US AGM 65 Variants).

 

And if that is the case then the RB 75T was fully used on the AJ and AJS 37 Viggen =P

(Side by side with the Normal RB 75)

and i doubt it would need any modifications to be used as it use the same seeker and guidance units etc as the AGM 65A/RB 75 did.

 

The RB 75T with its heavy warhead was to be used against Bunkers,Bridges landing craft and in general tougher targets where the heavier penetrating warhead was needed.

 

With the Normal RB 75 (AGM 65A) with its Shaped Charge warhead being used against vehicles etc.

I cannot wait to hurl Bk90s

[microvax]

Glorious.

 

MJ2 is self targeting like the skeets right ?

At least the swedish wiki article and the ginormous weight for a submunition indicates that.

[BravoYankee4]

Same here. I guess a group of Viggens with BK90's would end the current discussion in the Blue flag event about clearing out the last few airfields ;)

True, but the BK90 would probably be banned from the current BlueFlag 80s round. :D

When was it introduced btw?

Just about answers it, thx Mattebubben :beer:

[renhanxue]

Mid-late 90's. The national archives library catalog says the technical description was published in 1998, so probably around that time.

 

Which reminds me, I should go photograph that.

[zerO_crash]

Is there any chance of getting the manual on beforehand? Would be nice to get time to study it.

[renhanxue]

I can offer you the unclassified parts of the JA 37C flight manual in English if you want, just need to turn it into a PDF first. Many (but far from all) of the subsystems are the same or quite similar, after all...

 

Speaking of which though, poll: what should I request declassification of next? Some ideas I have kicking around are:

- SFI JA 37

- Taktiska anvisningar för attackförband, 1970 or 1982 edition

- Classified parts of the AJ(S) 37 systems overview binders

 

If you have better ideas, post away. I'm leaning towards Taktiska anvisningar, myself. SFI JA 37 might take forever and a half to get declassified.

[zerO_crash]

Well, anything in english would be nice.

[Krieg]

One vote for the Tactical Instructions for Strike units. The 1982 ed would probably be better if possible as it would be regarding the Viggen rather than Lansen. Thanks for your great work!

[Skjold]

Although the Tactical Instructions sounds interesting, SFI JA 37 is my choice.

[JanTelefon]

The tactical instructions would be a treat. Preferably with as much Viggen in them as possible. :)
