The AJS-37, Improved viggen

[strv122 391]

Overview:

The AJS-37 is a modification of the AJ-37 attacker. Like the Aj-37 it is a Delta canard jet powerd attacker made by SAAB. The planes were modified betwwen 1991 amd 1994, They left service in 2005 with in total 48 AJ-37's being modified to AJS-37's.

Between 1991 and 1994, the modification of AJ 37 was made, which was the first in the modification program of AJ 37, SF 37 and SH 37, in order to give the aircraft a limited JAS(Multirole) capacity. The modification of AJ 37 increased computer capacity aswell as the posibility of using the new Anti-ship missile robot Rb 15F, which was developed for the JAS 39 program. Bomb capsule M/ 90(DWS39) and Rb 74(aim9L) were also added as armament alternatives. Modified aircraft could also carry Sidewinder robots on the outer wing hardpoints, something that only JA 37 could before. In addition to attack and hunting, the aircraft could also carry out reconnaissance missions. The modified aircraft were therefore designated AJS 37 and were placed at the Skåne air flotilla (F 10) in Ängelholm and at the Hälsinge air flotilla (F 15) in Söderhamn.

Added 'no' options for question #2

[Miki_Hoshii 2,449]

Hello strv122,

 

Thank you for your suggestion submission, however all poll questions require a 'no' or negative option. I have edited in a 'no' option into question #2 to make it compliant with forum suggestion guidelines.

Please Do NOT :

 

Naturally, there are also a few things you should try to avoid at all times. Those things are the following:

 

-  Create polls that don't include a "Negative" or "No" answer

While polls offer a good and simple way for individuals to quickly express their stance on a subject, without having to elaborate it in detail, there are ways to manipulate polls to always show a desired result. To avoid having an unfair voting system, make sure to  always include a negative option to a question so that it's fair and unbiased. If this requirements isn't met, the thread author will be notified and the poll will be altered to provide a fair voting system.

 

Open for discussion.

+1, yes please.  I would very much like to see this added to the Swedish air tree.

[KekDermott@live 552]

+1 for me too. could have this after the AJ37 (or as an upgrade package maybe?).

either would work, though how would the designations work? its pretty clear that the ones that were upgraded were called ajs-37 and never as aj37

[Asghaad 2,476]

id say AJ37 could be event/battle pass reward but i would really much preffer the version that has basically the same characteristics but isnt completely useless at BR above 10

 

so if one has to be chosen id rather get the AJS into the tech tree

Again Asghaad this Viggen is a ground attack plane, you need to consider it's capabilities in ground rb (ordinance will make a big difference) over it's capabilities in air rb.

[Asghaad 2,476]

considering the ground strike capabilities of AJ37 and AJS37 are nearly identical and the anti air capabilities are whats differentiating them i dont see a problem with preferring version that is useful in BOTH realistic modes instead of being useless in one of them

 

as AirRb player only, the ground strike capabilities of any platform are frankly irrelevant to me, but its ability or lack of thereof in air to air changes the "please dont screw AirRB over even more than it already is" into "might be nice addition"

 

AJ37 would be horrible detrimental piece of junk making teams in AirRB lose more by being useless there while AJS37 would be both useful in ground RB and it looks to be also well equipped for AirRB.

[RanchSauce39 397]

also shame no cluster muntions in war thunder yet. FOr  the AJS37 viggen would also have acess to BK90. Ot would be brutal but awesome.  BNk90 is Standoff INS guided glide cluster bomb dispensor

Wouldn't the JA 37 Viggen be a even better option. Better radar, engine, weapons, maneuverability, and the advantage of being the only Viggen with a permantly mounted "Autocanon/gun" with a ballistic computer?
And we definitely need the RBS 15 if we ever get the AJS 37

you would add both

2 different roles though.

 

Ja37 was Fighter/Interceptor, with some secondary ground attack. It can use radar guided missiles.

 

AJ37  primarily Ground attacker, with secondary a2a  ( IR missiles) for self defence purposes. No radar guided misisles. Although the Aj37 Viggen can mount gunpods, it does have no leading computing gunsight solution.

 

Different avionics suite too. JA has A2A radar, whereas the AJ37 has an AIr to surface/sea only radar, and some additional  guided munitions unique to it like the anti shipping missiles, that can be used with the radar.

Now with the introduction of AGM65's this means that the viggen would probably get the Robot 75

That is what I mean, the JA37 would fit nicely since it is designed to be a fighter, so you would be able to have some more use of it in Air AB/RB. But I would still love to see both AJ37 and AJS37 added, we need something after the A32 and the Saab105 in the tech tree to use for CAS. 

But as you write, the planes have completely different roles

 

And with the introduction of the AGM65, the RB 75 wouldn't be wrong, or the RB 15 for use in naval battles if we ever get more modern ships.

The JA37 seems to already be in the works and therefore most people want the ajs in to complement it and the swedish tree

I dont understand why people seem to think that planes will get all their possible weapons if its not fitting the state the game is in.

because swedish players will cry if they don't have their own SARH missiles ? wich i can understand

To be fair, the swedish community is honestly the least crying nation in the whole game, I have not seen any other ingame nation players cry less on the forums than the swedes.

Well, maybe having a lower repair costs as a whole wouldn't hurt.

that's a problem for all the minor TT because only high lvl players play those nations and they increase the stats of certain vehicules wich are the exact same as the design nation

[supersaiyan9751@live 366]

+1 for the attack viggen.

Not necessarily. People also play them because they can be fun.

Sweden is easy for anyone to master actually. As soon as I started using Sweden, I learned how to master it and at the time I only had a squadron 262 as a jet and I barely ever used anything besides bombers.
