I know other types were in the mix and the Skyhawk won its just an assumption on my part that the Army was already stretching things kicking off in the first place and that even if they got it over the line no way on earth would a foreign type be tolerated.

Well, Hawker got a US licensee and I could see SAAB doing the same thing at a later date.  Wonder who they would pick?

Wouldn't it be the same licensee ? I've read that Hawker (HS) and SAAB were/are closely associated ---

Off topic but that's an idea, after the initial comp the Army initiates a more formal one (following the USAFs continuing failure to provide the sort of support the USMC takes for granted), Hawker enters an evolved FGA Hunter and wins.  When the Hunter comes due for replacement the Hunter team enters the Viggen.

What if a Viggen powered by F100 or F110?

It might be possible (length, weight and thus wise) except the diameter gets in the way - the RM8 is 1.03 m in diameter whereas the F100/F110 have a max diameter of 1.18 m.

Was there another potential turbofan engine that Saab could have included in the Viggen's design, which could have curtailed the issues of its export potential thanks to its use it's American Pratt & Whitney JT8D engine (Volvo RM8)
(P.S. I'm aware of the original favoured turbofan being the Rolls-Royce Medway engine...)

Possibly a RR Spey version or TF41?  Another that might have happened would have been the P&W F100 but this gets you back to the US issue.

Of course changing from 1 engine to two might have opened up other possibilities.

The Rolls-Royce Olympus was actually proposed as well.

A while back there was an article in Air-Britain's AeroMilitaria about alternative power for the Viggen. IIRC, the Spey was a straight swap, the Olympus required a fuselage stretch along with some rear fuselage modifications. The article had some 3-Views of the lot. It was banded because the aircraft was offered to the RAF (IIRC)

Thanks GTX and kitnut627 👍

The RR Spey sounds more straight forward and logical in terms of R&D and engineering. I'd also assume Britain isn't as 'hats on, hats off' geopolitically and commercially like the U.S.....either.

P.S. thanks for the line drawings kitnut617

M.A.D, the information in the article was discovered by the researcher at Kew (National Archives) while he was actually looking for something else.

Whilst on the topic of the Saab Viggen, does anyone know how many potential Viggen's were part of the Indian Air Force assessment? 🤔

I would presume similar numbers as eventually for the Sepecat Jaguars.

It seems to be a common theme lately, a story about something appears in Air-Britain came about because it was found in a file box while the researcher was going through it looking for what he was looking for, basically they have to check every bit of paper in each box because it's not in order and the snippet of info isn't on the box contents record sheet.

Found another version.  Translated from a Swedish book on the Viggen.

Nice find Carl.

I've just been on SPF and there happens to be something added to the Viggen thread there this morning too. I noticed I had made a comment about where the above file was found.
So a correction: it was found at Rolls Royce Heritage Trust Filton by Clive Richards who then passed it on to Tony Buttler, who then published it in the 2016 Summer AeroMilitaria quarterly.

Would be interesting to attempt to build the XE-3 version.

A couple of Viggen kits mashed together with the back-end of a Tornado perhaps?

I think the rear end of an Arrow would be better. You could even use the air intakes too ---
