DCS: AJS-37 Viggen Discussion

[Cik]

my guess is that it's the exact same function that the F-16 does while in ACM radar mode.

 

the AIM-9 seekerhead POI "jumps" to the radar's target and then does a small scan, if it finds something you can shoot it.

 

also ranging information, though tbh it's never seemed that useful considering if you are boresight locking you can shoot no problem except on a very cold target.

[Jediteo]

There is no cueing ability of the radar. You don't really lock targets more than designating them as the range target (place the sight over the target and cycle the fix trigger to the first detent), somewhat similar to the ranging radar of the F-86. The seeker head of the RB24J and the RB74 can be uncaged once they get a tone.

[BravoYankee4]

I know and i have never stated otherwise.

 

I was Curios if it had the abillity to slew the IR Seeker head but never assumed it could.

 

I simply stated that the Manual confirmed the abillity to lock up air-air targets and feeding range info etc.

 

 

 

 

Im not talking about the radar guiding the missile.

 

Im talking about the Radar being able to slew the seekerhead around (on while on the pylon)

to whatever target was locked up making it able to get a good lock at an enemy

(seeker head could still lock any target in that area since it was not locked on the radar locked target that way)

 

Allowing for a Seeker lock at a target not directly infront of the missile etc.

 

And i was curious if the AJ(AJS)37 had this abillity to slave the Seeker head to the Radar.

 

As i am yet to find evidence either way =P.

 

Im leaning towards that it might not be able to do that but im still looking.

 

I wasn't arguing with your statement, more of elaborating in the same direction. This would have been so much easier if we had a Swedish sub-forum ;)

[RagnarDa]

Reading the documents I'm with mattebubben on this, it clearly says "låsning" which I would expect being the same as a lock (just like running the F-16C in ACM Bore Sight Mode)?

What did we miss?

 

 

Long answer: when sending out beams when "locking" in air/air mode the radar uses two return intervals, one "long" and one "short". It sends out a beam and waits for the return on a specific time, either the long return interval or the short one. At first the intervals are set close to the aircraft, where the short one is the time it takes the beam to travel the closest possible distance and back and the long one is the time it takes the beam to travel to a slightly longer range and back. If there is no return signal in, for example the short range interval, the intervals are increased proportionally until both intervals has a return signal. If there is a return signal in both timeframes the interval is frozen. This way the air is longitudinally scanned until both intervals has return on a somewhat common distance, and that distance is where the target is assumed to be. There is no information about the bearing or pitch to the target when "locking", and the wording is a bit confusing. The point of why they designed it this way is to minimize interference, esp ground interference.

[theOden]

I see.

So locking the target is not locking the target but successfully measuring the distance.

(rather than "instantly" getting the range to target using normal radar puls return time, to avoid ground clutter)

This makes me consider the PS-37 way less effective AA tool compared to the PS-01 of the previous J-35 Draken.

Strange.

But i guess in the early AJ years the Draken was taking care of air targets (until JA37 came about).

[RagnarDa]

Yes, and my guess is also that unlike the Draken it was designed to operate close to the ground and this was one way to hunt at those altitudes without using Doppler-technique.

[theOden]

I guess.

And yes, while AJ37 might be capable of some 50000 ft ceiling I would say its effective ceiling is 1000 ft

:)

Also, since AJ means J in secondary role I guess it would be used against non-escorted heavy bombers etc. and not against agile fighters.

 

Oh well, still looking forward to try this one out - there is even a huge risk I will sidestep my rule of not buying beta-releases ever again.

[mattebubben]

From the DCS News Letter.

 

In the first half of 2016, several new 3rd party aircraft modules will also be launched. These include the F-5E Tiger II by Belsimtek, the SA342 Gazelle by Polychop Simulations, and the AJS-37 Viggen by Leatherneck Simulations.

 

So if thats correct then the AJS-37 is not to far away.

[jadebullet]

I don't get what this talk about the Viggen not having radar missiles is about. It was able to carry the Skyflash missile, and is also the only plane in existence to get radar missile locks on the SR71 when they were on their return leg, despite the ECM jamming. (The targeting computer was fed data from ground controlled radar. This would happen pretty regularly and it is believed that had a missile been fired, it would have hit.)

 

I personally can't wait to fly this beast.

Wrong Viggen.

 

JA 37 is the fighter variant that carried the Skyflash and later the AMRAAM.

The variant we will get is the (upgraded) attack variant, AJS 37.

 

J = Jakt (Interceptor)

A = Attack

S = Spaning (Recon)

 

They are in order of relevance, so the variant we're getting is AJS.

 

(A)ttack first, (J) Interceptor second, only AIM-9 and (S) recon third.

Ok LNS, can you guys please just announce this thing now, so we can droll at some screens???

If you read back a "few" pages you will notice that it has been explained several times that the AJS 37 is a ground pounder and more or less only ever carried AA missiles for self defense, and it was only able to carry AIM-9 missiles since the radar was aimed at the air-ground role, and wasn't even remotely as capable as the interceptor variants counterpart in Air to air functionality.

 

As others have said you are thinking about the interceptor variant (JA-37), which is a completely different aircraft in almost every way. :-)

I'm glad we get the ground pounder. We are flush with interceptors, time to move some mud in a fast mover!

Hi all, I don't exactly feel like spitting through tons of pages, and the search option doesn't work correctly for me for some reason, has anything been said about the armament we will get with this beauty in DCS?

Thanks, some nice sequences with the radar in action.

Not sure what LNS is giving us, but here's what is available with the AJS upgrade version of the Viggen.

What BravoYankee4 said but also, everyone must admit that the coolest of them all is the SF-37, looks like a shark mixed with a Ferrari.

I will not take "no" as an reply :)

Here you go:

 

Rb 04E (Anti ship missile)

Rb 15F (More modern anti ship missile, originaly developed for the SAAB 39 Gripen)

Rb 05 (AG missile guided by a joystick in the cockpit. The missile could be fired instantly as soon as a target was spoted and automatically steered in front of the aircraft where the pilot could se it and visually guide it towards the target. It had a liquid fuel rocket engine that did not generate much smoke, and had a tracer element increasing it's visibility to the pilot. It's similar to the AGM-12 Bullpup)

Rb 75 (Maverick TV guided missile)

• Raketkapsel m/70 (Rocket pods with 6 13.5cm rockets, up to 4 pods can be carried at once.)

• Sprängbomb m/61 (120kg conventional bombs)

Bombkapsel 90 (standof cluster bomb system developed for the SAAB 39 Gripen)

• Two external 30mm autocannon pods can be equiped for air to air engagements

• Up to six Rb 24 or Rb 74 missiles (both of these are AIM-9 Sidewinder variants).

 

It doesn't have any internal countermeasures, instead it relies on external pods for this functionality just like the MiG-21bis.

[theOden]

Add to that the Rb 75 also comes in Rb 75T which has a heavier blast warhead (just like the copy-cat 'mericaans later added with the AGM-65G :) )

 

And more important (importanter if you like beer), the Rb 04E looks like a Star Wars Tie Fighter so it must be good or plain awesome.

[CoBlue]

The Viggen is first, however, yes.

"Viggen you're cleared to land nr:1"

I'll say he's on a short final now

I'm so thrilled about this future release and I would do anything to be able to help.

Following pevious post...

I have seen landings like this under my mil service in Sweden and I can just say it is more then VIOLENT!
