“Reinforced metal matrix composites (DRMMCs) is not CMC either.
Say whut?
A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. The other material may be a different metal or another material, such as a ceramic or organic compound. When at least three materials are present, it is called a hybrid composite.
Ceramic fibers in CMCs can have a polycrystalline structure, as in conventional ceramics. They can also be amorphous or have inhomogeneous chemical composition, which develops upon pyrolysis of organic precursors. The high process temperatures required for making CMCs preclude the use of organic, metallic or glass fibers.
If its reinforced or not is irrelevant. A MMC can have ceramic components and a CMC can have metallic components.
So a DRMMC could in some cases be called a hybrid composite or CMC depending on what it consists of.
Mirage III is probably the best jet from that entire era. I think there was a thread about it.
So its turbine fanblades made from composite materials.
How does this picture add anything to the thread without an explaination?
Well. I think they did the right choice in picking Rafale considering all factors.
Performance wise the Gripen is pretty close but it does not offer the same level of independence which in the case of India makes perfect sense.
There where only two choices (the American and Russian companies never had a chance and Gripen wasnt from a one stop vendor).
That were forced into mass production despite several shortcoming revealed during testing, which had still to overcome.
I see history repeating itself…
The problem is that the IAF probably wants to use it as a pure MULTI ROLE fighter, and not just a pure Light Interceptor..With Integrated avionics, AESA radars and optical sensors, the MRCA designs do offer quite a bit of capability for the strike role and this capability would be valuable and greatly appreciated…
The EF2000 passed to the final and the a2g performance is pretty rubbish. I think this summary from Wikipedia says it all… And the operators replaced it with the F4 in Unified protector.
Air-to-surface missiles:
AGM-65 Maverick, in the future
AGM-88 HARM, in the future
Storm Shadow (AKA Scalp EG), in the future

Penguin, in the future
AGM Armiger, in the future
Bombs:
6× 500lb Paveway IV, in the future
Paveway II/III/Enhanced Paveway series of laser-guided bombs (LGBs)

What India wanted was a jet that wasn’t sensetive to third party embargos (bye SAAB) and a high performance platform. So they only had two options left.
..and they don’t want to kill Tejas just yet.
…and yet negotiations are on hold. The Gripen makes a lot of sense, but you have to remember that the savings of going with used Eurofighters would cover a lot of operations and the long-term roadmap of the Eurofighter is much more secure than that of the Gripen.
Here is what you don’t seem to get. Even if the Gripen NG actually materializes, it is still in a precarious position with only two backers, neither of which has deep pockets. The Eurofighter has a far larger base of users and will certainly receive more future upgrades over its life than the Gripen.
The contract equals to 2% of the Swedish export any given year. Of course there will be negotiations, I mean how did it look in Thailand, South Africa, Hungary, Czech Republic? The situation still is Gripen or nothing and they will get something.
This is where SwAF are today. Gripen C wont cut it in 10 years from now so something has to be bought. Gripen E offer the desired performance and is the cheapest option on the market. The SwAF will get at least 60 Gripen E. End of story. Because they, just as the swiss, will buy something and there is only one option.
The Eurofighter T1 has nothing to offer. First off, the tender is closed, this means no more bids are accepted. Second off all, the T1 has almost no AG capabilities and needs a serious upgrade that will put the jet right back up at the same price as last time… but with higher operational costs.
Oh, btw. You might want to look at the still ongoing negotiations regarding the F35… 5 years after the formal joining of the programme there is more controversy around it than ever for most partner nations and many are considering cutting their orders (like Netherlands, Italy, Australia, USN etc). The Gripen order looks pretty solid in comparison and the Grien e will materialise as it already is funded for development.
Another serious issue is that the entire Gripen NG program is still in doubt. The Gripen NG’s development is dependent on one single less than fully committed buyer. If the Swiss opt for used Eurofighters the Gripen NG may never be developed.
Even if the Gripen NG is ultimately developed its long term prospects just aren’t that good. Who will fund the next round of Gripen NG upgrades in 10-15 years? Who will pay to integrate new weapons onto the Gripen NG in the 2030s?
You still havent understood it. The development is already funded, the Swedish acquisition is accepted but with funds uncommited (thats a different thing btw). (The government is allowed to reconsider the buy of 60 jets but has payed for the R&D).
The Swiss have accepted the offer, only undecided part is the funding. But politically its a done deal. It’s Gripen or nothing and there will be something so Gripen it is. Getting the cheap early Eurofighters would be a foolish mistake that only Austrians could think of doing (and spend their days regretting it).
If you want to go to history, check out how SAAB has delivered on their promises. Did they or did they not deliver the Gripen system on time, with higher than agreed performance at a lower cost than agreed? There are a few arms manufacturers that actually can deliver and SAAB is one of them, General Dynamics and Lockmart are not.
IRIS-T only? No a2g munitions?
Does a 27mm mauser cannon count?
I like the concept but why are the wings so oddly shaped? Wouldnt you get more lift and equal drag if they where flat? + lower RCS from the sides…
During the Cold War Sweden lost over 600 pilots, 21 per year throughout the 50s while mostly sitting in the flying barrel.
The problem wasnt the jet but rather the combat like excercises with igh speed and very low alt maneuvering. I think the barrel can claim over 210 lives and the Draken a similar amount.
i’d add Mirage IV P (patriotism…:) )
I just dont think its a big enough difeerence between Mirage III and IV to put both on the list. Just the same way as I don’t put up the Su30, 35, 37 along with the Su27.
And if you look carefully it’s on the top part of the list. 😉
This ill end up the same way as it always does. we have the usual suspects, ie:
Draken
Concorde
Mirage III
YF23
Pak FA
Mig 29 (twin seater and not the hideous version)
Su27
SR71
the maybe list:
B1b
Tu160
Tu22M
Rafale
F22
Mustang
Spitfire
F15
Gripen (almost forgot)
And after that the list becomes a fugly-contest.
I think the F35 will come out on top. Nobody can match its sustained 4,1G and 50 degree AoA…
Its the best WVR fighter evur made.
RCS reducion come mostly from shaping ( i mean major chance , not just adding radar blocker for the engine )
Depends on what you start with.
In the case of MiG 31 you need to stay with straight air ducts (maybe tilt the side slightly). By that you ar limited in what is and isnt possible. Anyway, I would loike to se more composits in it (if its possible) and som minor stealthification mods.
But if you think about it, it is a huge aircraft. Why bother to stelathify it when all design choices are made for speed and speed alone.
