Very much depends on what is meant by austere operations. Or by what distances your taking about for takeoff and landing with what weapons fit.

I think that the KAI KF-21 is in the order of 25 tonnes, as is the not-yet-launched HAL AMCA. What would SAAB design to avoid competing with these? How small can a fighter be and still carry a meaningful weapons load internally?

With that in mind....
GB 150
Japan 150
Italy 85
(A quite plausible Saudi Arabian buy) 55
I follow Indian military aviation. It is possible that their own 5G AMCA project will end up being cancelled through India's inability to organise (and reluctance to finance) development of a suitable engine. It may be very advantageous for the GCAP group to keep talking to India about possible involvement in the program either as a co-developer or as a customer. india will need to start replacing 250+ Su-30 fighters from mid/late 2030's(?) so might be in the market for 100-150 frames if AMCA is cancelled/abandoned.
How small can an aircraft be, but carry a meaningful internal load, well I suppose you would need to look towards the F35 for that metric....

It should be possible to develop an aircraft that can compete with F35, using next generation manufacturing and key technology from Tempest.

I would be extremely weary of allowing India into any high end military programme, they remain non aligned and just as likely to share technology with Russia.
Their silence over Putin's invasion of Ukraine and filling their boots with Russian oil and gas post invasion, tells you all you need to know about their reliability as partners today.

That doesn't mean there isn't a defense need. All those Typhoons need replacing and as much as the little boys here think the F-35 will be an adequate replacement for Typhoon in the second half of this century, it will not be. Go check how the F-35's did in exercises against F-22's (spoiler, not well) and think that the F-22 has roots back in the 1980's. Not hard to imagine that China and maybe Russia will have an F-22 equivalent one day in the not to distant future. That's why the US is developing a 6 gen fighter.

I'm not sure exactly what @SW1 meant when he said if the F-35 was made in the UK, there would be no Tempest program. I don't know how a UK F-35 production line would address the UK industrial requirement for Tempest that goes far beyond license manufacture, and as I said, militarily it doesn't fit either.
You do know that the UK is a tier one partner don't you Ron, so 'licence' manufacture wouldn't come into it.

Happy new year Mr Grumpy 👍
Not any more. Please keep up.
Not anymore??? Not grumpy??? new years resolution perhaps Ron...

See, it's not all bad news at the moment folks, Rons going to try and play nicely in 2023👍

India is non-aligned. It does not follow that India is likely to leak secret information to Russia about western weapon systems it has or is likely to leak secret information to the west about Russian systems it has. Same applies to technological secrets.

Agreed, India has not condemned the Russian invasion of Ukraine. India has repeatedly called on both sides to settle their differences by diplomacy.

Undisclosed advance commissions ie what everyone else does. Maybe the world would be a better place if developing country x bought Sukhois instead of Gripens ( because that’s their market - let’s face it they ain’t gonna win against F35 ).
Sweden has a choice - do they want to be in the aircraft business?

Some thoughts on GCAP from Richard Aboulafia

https://richardaboulafia.com/november-2022-letter

He notes that the US NGAD fighter may not be offered for export. That would leave the 6G market to non-US types.

The radar and avionics of a shot down SU35 that went for a little (alleged) wonder to the UK last year, proved the Russians are still 'a long way' behind the technology curve quite frankly, so there's not a lot we can learn from Russian tech in Indian service, as their Su30's are a decade behind the 35.

The reverse is unfortunately not true, I'll bet the Russians have already had a very good look at their Rafaels.

Quite frankly Spitfire, the Indians quietly saying "steady there, play nicely" like a useless meak school teacher with an unruly class, simply dosen't cut it.

India has unfortunately shown itself to be an unreliable partner, in an era when right thinking nations are stepping forward and firmly hammering their colours to the mast.

I hope they don't look towards Russia for help if China attacks, I doubt their loyalty to Putin will be rewarded..

Like BAE Systems flogging a dead horse with the Hawk and effectively finding itself out of the Jet trainer business while excellent Italian offerings prosper, SAAB is just about reaching the end of a developmental cul-de-sac with Gripen E.

If they don't hitch their wagon to either Tempest or the Franco German offering, then they are signing their death warrant as a fighter builder...

That would be absolutely tragic...

Let's remember that we can break even as planes but also as components.

IMHO for this reason is key that the Swedish government understand how important Tempest it is.

Because If Tempest is too much for 3/4 of the world a single engine/Griphen with Tempest tech inside would be perfect for past export countries like Brasil&Visegard, plus at the same time it could attract the Russian clients that Ukraine is going to make Sukoi loose (thinking of Peru for example, but way higher chance they will go for KF-21 considering their Korean ties).

Yes, it is an idea for SAAB to design a Gripen G using the engine and subsystems developed for GCAP. Economies of scale would accrue to both Gripen G and GCAP programmes. Component commonality with the Tempest fighter would also make it a good stablemate for countries with large enough air forces to run two types. For example, UK: Gripen duties could include air policing, interception; Tempest could cover the more demanding roles.

An often used industry metric in new military aircraft programmes was a build of 400 units to make a program economically viable and not cancelled due to spiralling costs at birth.

it's particularly relevant when discussing very high end fighters like this, as fail to get sufficient numbers under contract at the start, then the unit cost becomes unacceptably high for the partners and into the bin it goes.
Utter rubbish.

Absolutely Meriv, SAAB would be an excellent partner, I have doubts that they could survive with their current business model past 2035 without a new project....

India is not a partner of the west. Definitely not a partner of US. US applied sanctions when India tested a nuclear device about 20 years ago. All the R&D and dev work done on their LCA fly-by-wire system in US was embargoed, meaning India had to start more or less from scratch again by on its own.

India is under constant attack (several times a week) by armed militants crossing from Pakistan. US favoured Pakistan over India while conducting its Afghanistan operations, to India's cost. You can surely understand that India does not see US as a country it would want to be rely on. It has proved to be unreliable in the past. In recent times it has given support to a country seen as a 'terrorist state' by India.

To me India should have condemned Russia's invasion of Ukraine. Not because it invaded an 'ally' of the west. Because it invaded a sovereign country.

Nato has a definition of what an austere airfield means. As it does for the other types of airfield.



On a wider point, I wouldn't believe everything that saab says about gripen operating with a couple of conscripts, how quick they can change an engine etc. A fair bit is smoke and mirrors.

I suspect those definitions are not what was being opinionated about here though.

Design requirements on the aircraft I suspect from those documents and others have been incorporated into aircraft we have designed in the past and I suspect will continue to be in the future.

I don’t believe there is that much of difference between typhoon and gripen in this regard.

Spitfire, I absolutely agree that India should have totally condemned the Russian invasion, filling their boots with Russian oil and gas was disgraceful behaviour, effectively underpinning the Russian economy and fanning the flames of war, along with China.

India hasn't come out well from this, they have created
serious mistrust and doubt among potential allies if China ever attacked.

They are perfectly happy to profiteer from Ukrainians agony and it leaves a very bad taste indeed...

They best hope the West doesn't take the same attitude if China seriously attacks, it would indeed be karma!

I bet they would scream from the rooftops for western help!

It is pretty distasteful that the Indian government have clearly instructed the Indian police not to investigate the recent deaths of the two Russian businessmen on their joint trip to India.

That said, this is more than a little suspicious itself and it seems entirely plausible that the UK govt had similar conversations with our own police:

Yes it's a bit more than how long the runway is.

This type of thing comes into fashion every now and again, it gets tried every so often and then quietly dropped when reality appears.

From my experience, I'm sceptical that beyond the odd bit of refuelling etc, there's good reason no-one really does it. I don't include PR events in that. I mean doing it properly and consistently.

Yes access to ground support services will drive you quickly to more traditional facilities for repeated use as I can’t see all the equipment required being lugged to forest clearings. This will become complicated further with low observable aircraft characteristics.

A number of the nordics “road” operations are roads surrounding the main base which the aircraft have access via taxi ways from the base

Indeed many aren't in the middle of nowhere but very close to the base. Best though of as a back up runway rather than 'austere operating' in the middle of nowhere.

Your point is incorrect, leonardo in the uk was involved with the tempest program prior to Italy joining it. US owned companies in the UK are involved with tempest are they now to be considered partners too.
