[Coyotte]

Hello there !

 

Firstly, thanks to share all theses files... Really appreciate, even if I don't speak swedish :D

 

 

Does anyone is able to share somes files about endurance/ fuel cons. or anything else what could help us to plan flight more realisticly ?

:helpsmilie:

Now that's something I will read through! :thumbup:

[TOViper]

Don't think so, but ... is there an English version available?

Not for free, but consider it buying if there was an English version ...

[TobiasA]

Yes! Please pin it, it is awesome!

I'm just starting with the viggen (and swedish) so this is a great possibility to learn both. Struggling to get started, because I finished the training missions and feel like I just scratched the surface...

An article about the SK37E variant in Swedish i just stumbled upon while searching for the U/22A

Maybe it's interesting at some point.

 

Edit: the site actually got a whole library of pdf files which seem to be about Swedish airforce. Maybe a swedebloke can have a look if theres something relevant for us? -> https://www.fht.nu/fv_dokument.html

 

Edit 2: https://www.fht.nu/fv_dokument_fv_nytt_80_tal.html 

 

That's scans of the official air force magazine (the title literally translates to "Air Force News"). It was published 4-5 times a year between 1960 and 2003. There's a number of interesting articles in there but as an offical propaganda outlet it's not always the most useful source, and it's usually pretty thin on the sort of interesting details nerds love to see.

 

Also, that page only has some articles scanned. Here are scans of every issue 1960-2003: https://www.aef.se/Flygvapnet/Tidskrifter/FV_Nytt/FVN_oversikt.htm

I remember reading Flygvapennytt when I visited my cousin, but to be honest the article that have stuck the hardest in my memory was the very early pictures of Mig-29 and Su-27's taken by Swedish and Norwegian air force pilots checking out Soviet planes as they where getting close to the borders.

Google recently did as they are wont to do and broke a bunch of links for some convoluted reason. Seems to only have applied to people who had never opened the link before, so it probably didn't affect any of the usual suspects, but if you found this thread recently and one of the Google Drive links asked you to log in and request permission to view the document, try again now and it should hopefully work without any of that nonsense. Let me know if it doesn't.

That's the unclassified part, which is almost identical to the one for the JA 37C which is already in the OP (although that one is in English). The interesting changes on the JA 37D were all classified and as such aren't in the unclassified part of the manual.

With the exception that has information about the middle display and the scratchpad below it wich i am highly interested in.

This thread has been dead for years because I just didn't have the time to visit the archives anymore. That doesn't stop other people from visiting though, and Heatblur Discord user VF-103 AJ made an attempt to get the tactics manual for the AJ 37 squadrons declassified, with a little bit of assistance from me. We ran into some trouble with the officially published version from the mid-80's, but we did manage to locate a draft version from 1975 and get that declassified. Some of you have been waiting since at least 2017 for this, so it is with great pleasure I present to you, the Proposal for Tactical Advisory for Strike Squadrons, 1975 provisional edition:

Förslag till taktiska anvisningar för attackförband, 1975 (TAA 75): provisorisk utgåva, issued by the 1st Air Group (1. flygeskadern, E1), 19 June 1975, in 10 numbered copies. This is copy number 1, stamped arkivexemplar (archive copy), found in the national military archives, specifically in the archive of the 1st Air Group, ops section, classified series F II, volume 1. There is a distribution list on page 2; copy number 2 and 3 are not accounted for there, but numbers 4 through 7 were issued to the commanders of the strike wings (the 6th, 7th and 15th wings; the 7th wing was issued two copies) while copies 8 through 10 were retained at the E1 headquarters. I'd expect this to be the only surviving copy of this version of the publication; the others should have been burned according to standard classified document archival procedures.

Unfortunately this draft version is not complete and is missing several chapters as well as many of its appendixes. The cover letter states that this is simply because not all chapters were finished at the time of issuing and in some cases additional field trials were required. We do however have our sights on another copy from 1980 that may be possible to get declassified, so stay tuned for that.

All credit to VF-103 AJ, who did all the actual work of going to the archive, photographing the documents and assembling the PDF. I mostly contributed some arcane knowledge of the national archives search engine and some tips on how to deal with their bureaucracy.

A huge thanks to you! 

Question: How do I see in the document that it is no longer hemligstämplad? Just curious. Do I see it at all?

Edit: Ah, wait, if it is available in riksarkivet then it is no longer hemligstämplad, I guess...

Usually they cross out the classification stamp (HEMLIG) in pen when they declassify a document, but they're inconsistent about where and how they do it. It seems to vary from archivist to archivist. If they're feeling particularly meticulous they do it on every single page including a signature and a date from the archivist that did it. Most of the time they only cross it out on the first page though. In this case since it's loose pages stored in a cardboard box what they usually do when they declassify the entire box is just cross it out on the outside of the box, instead of crossing it out on the first page of every document stored in the box. It'd look something like this (entirely different and unrelated box, though):

Strictly speaking the stamp doesn't actually have any legal effect or anything like that, it's just a reminder to whoever is handling the document that when it was written it was considered to contain classified information. The information required to know if something should or should not be classified is generally classified in and of itself, so as an outsider you can't know. You could contact the national archives to verify, I guess? Anyway, you're correct, we got it through official channels and if they hadn't declassified it we would never have been allowed to see it, much less photograph it.

Sometimes when they declassify an entire box like this they mark it as declassified in the archive search engine and in that case you would see "avhemligad <date>" in the link I provided to its location in the archive, but they don't do it consistently; some of the archivists do it and others don't. They usually do remember to mark it as declassified in the paper version of the archive index, though!

In this thread, post real-life Viggen documentation such as flight manuals, maintenance manuals, instruction booklets, other military documentation such as reports, memos etc etc. I'll keep the OP updated with a list of documents.

 

To get us started:

 

 

Flight manuals and other official documentation

AJ and AJS 37: SFI AJS 37 del 1 kap 1 (open, unclassified)

 

SFI AJ 37 del 2 kap 1 (formerly classified secret)

SFI AJ 37 del 3 (formerly classified secret)

 

SFI AJ 37 del 2 kap 1 ändring 90 (pack of updated pages for SFI AJ 37 del 2 kap 1, formerly classified secret)

 

Minnelista för ff i fpl AJS37 (memory items/checklists for AJS 37 pilots)

Minneslista för ff i fpl 37 NÖD (emergency memory items/checklists for all Viggen variants except JA 37)

 

 

JA 37:

Aircraft JA 37 flight manual, volume 1 chapter 1 (English version of SFI JA 37C, unclassified part)

 

SFI JA 37 del 4 (formerly classified secret)

 

 

Non-specific:

 

Aerodynamik fpl 37: kompendium (pilot's introduction to the Viggen's aerodynamics and its aerodynamical development history, formerly classified secret)

Fpl 37 aerodynamik III: Manöverprestandabegränsningar, halvroll: kompendium (pilot's textbook on control surface performance limitations and split S performance, formerly classified secret)

 

Anvisningar för typinflygning fpl 37, 1985 års utgåva (lesson plan for getting your type rating on the Viggen, ~45 flight hours total)

 

Beskrivning bombkapsel M90 (technical description of the bk 90; open, unclassified)

 

 

Technical reports, assessments etc

NASA technical memorandum: aerodynamics of the 37 Viggen aircraft, part 1, characteristics at low speed

 

Saab JA 37 Viggen Performance Assessment (made by an engineer but with limited resources and without access to the original documentation)

 

Spinning the Viggen (article in a FlightGlobal issue from 1974)

 

 

Doctrine, tactics, service history etc

Med invasionen i sikte: en beskrivning och analys av flygvapnets luftoperativa doktrin 1958-1966 (Masters thesis in history; the doctrine analyzed predates the Viggen but it persisted largely unchanged when the Viggen entered service.)

 

Taktiska anvisningar för attackförband, 1961 års utgåva (Tactical manual for A 32 Lansen squadrons; predates the Viggen but as mentioned the doctrine was similar.)

 

Taktiska anvisningar för jaktförband, 1965 års utgåva (Fighter tactics manual for all kinds of fighter squadrons; again this predates the Viggen but tactics and doctrine remained similar for most of the cold war.)

 

 

Tangentially related reading

JA 37: Pilot och system

 

Lärobok i telekrigföring för luftvärnet - radar och radartaktik (Telekri Rr Tak Lv, M7741-850101)

 

Motmedel inom svenska flygvapnet 1950-2005

 

Anvisningar för telefonitrafik vid flygning

 

Ammunitionskatalog, data och bilder: flygvapnet (1984) (catalog of all munitions used in the air force, from .22 training rounds to missiles and rockets; handy to have around as a reference)

 

 

Just noticed there have been more documents popping up here in the recent years! Absolutely gold! Keep it coming as much as you can. Hopefully, Heatblur will feel an inner tick of nationalism, and decide on modelling the Draken! Delta wings are the thing, they always have! Honestly, Swedish tech is just fantastic. And I am saying that as a foreign agent who travelled to the wrong side of the Scandinavian Peninsula 

 

Jättebra, takker så mycket!

Hi @renhanxue,

I'm trying to slowly work my way through the real world manuals, as a non swedish speaking person, its a bit difficult and I have  a few basic questions regarding the manuals general structure and availability.  I hope you can maybe answer them shortly.

The Del 1 Kap includes the following general manuals overview at the beginning(red by me):

nullI'm a little bit confused, so my questions: (speaking about the AJS37 manuals only, not the other ones for AJSH37 or AFJF37.)

1.) Why does the overview here say that Del 2 consists of  Kap II-VI only, when there is also a Del 2 Kap I  which deals with SI and Radar?

2.) the Del 4, did it ever get declassified or become available?  Do you know what it deals with approximately?

3.) As a very crude summary is it to correct to say the manuals can be divided into this:

Del 1 Kap I = general introduction and aircraft description
Del 2Kap I  = SI & radar description and assorted attack procedures
Del 2Kap II-VI = procedures, limitations, performance

Del 3 Kap 1 =Performance graphs.

Thank you very much!

Kind regards,
Snappy

[renhanxue]

@Snappy They changed the structure of the manual between the AJ 37 and the AJS 37. The AJ 37 SFI is structured pretty much like you outline:

Del 1 (unclassified):

Systems overview of the aircraft, the unclassified parts.

• I: Beskrivning och handhavande (general description and usage)

Del 2 (classified secret):

The classified parts of the systems overview (chapter I) plus procedures, restrictions and some basic aerodynamic performance data.

• I: Beskrivning och handhavande (the secret parts that couldn't go in del 1)
• II: Flygning (flight procedures)
• III: Nödinstruktion (emergency procedures)
• IV: Prestanda, tabeller, diagram m m (performance, tables, charts etc)
• V: Restriktioner (restrictions)
• VI: Ändringar (changes)

Del 3, komplement (complement, classified secret, limited distribution):

Aerodynamic performance data.

• I: Introduktion
• II: Acceleration
• III: Stigning (climb)
• IV: Planflykt (level flight)
• V: Plané (descent)
• VI: Flygsträcka (distance flown)
• VII: Manöverprestanda (maneuver performance, or something like that - turn rates, etc)

For the AJS 37 they changed the structure such that what used to be del 2 kap 1 (the secret parts of the general aircraft description) instead became del 3 kap 1, and the complement with aerodynamic performance charts became del 4 instead. So, del 2 is then the "operational reference" part that you need for day to day work, with all the procedures and restrictions etc, while del 3 contains the less often used technical description.

 

See also Publikationsguide Fpl 37 for a more complete overview of all the documentation related to the whole aircraft 37 system, not just flight manuals but also maintenance manuals, technical orders, spare parts catalogs etc etc. Note though that this copy was published in October 1982 and as such predates the AJS 37.

Wow, thank you very much for your detailed and quick  reply Renhaxue! Especially for giving english translations to the different sub chapters, very helpful.
This clears it up a lot for me! Much appreciated.

Wish you a nice weekend!
