Perhaps someone has more infos about the Dassault proposal for the ECAT
competition, which was known as the Cavalier (not to be mixed up with the
VSTOL design with the same name) and which lost against the Br.121, later
Jaguar. It would have been powered by two GE J85 engines and was intended
to be built in a single seat attack version and as a two seat trainer.
I've attached the pictures I have so far, all showing the trainer version. Of
special interest for me would be a picture showing the undercarriage and the
single seat version. Was the Cavalier derived from another Dassault type, as
the Br.121 was a derivative of the Taon ?
(pictures from "Dassault-56 Years Of Aeronautical Adventure" and from
Flying Review 5/65)

Jens,

Are you lucky owner of a enlarged and updated edition of the book? I have only
"Dassault - 50 Years of Aeronautical Adventure 1945-1995" in my bookshelf ;D.

I don't think so... The Taon was Breguet LWF in 1956, ok.
At the time, Dassault had no less than three series of LWF (early Mirages, early Etendards, and Mystere development). This thing doesn't look similar to one of the LWF fighters... IMHO, this was build "from scratch".

Knowing how Dassault design bureau is working, be sure that some features of this design went into the Alpha Jet 10 years later ;)

Sud Aviation proposed the Northrop F-5 (but I never found drawings or photos of this project). The same year, Sud proposed the Cyclone project. In october 1965, The Minister des Armées said Sud aviation will never build fighters.

the SA 125 was the Northrop F-5 proposed by Sud in 1965. In the same year, De Gaulle leaved the NATO, and that's why this project was pushed away by the French Minister. We have no details of this project in the archives .... but if somebody wants to draw the French F-5 ;-)

Out of curiosity, were there any further ties between Northrop and Sud Aviation? I find it rather fascinating that Northrop seems to have been the most open of any US manufacturer to establishing ties with manufacturers in other countries.

Did you by chance manage to copy the drawings? I'd be interested in seeing such a beast.

Re: French ECAT Project winner - Bréguet Br.121......

Dear Boys and Girls, here is an article in French about the winning Bréguet Br.121 ECAT "project" which was developed into the SEPECAT Jaguar. I was surprised to see how much of the Jaguar is already there (the Jaguar is the only military fast-jet that I have any interest in; along with the similar Mitsubishi T-2/F-1). I cannot identify any Jaguar version that corresponds with the Bréguet Br.121B tandem 2-seater version illustrated that is not the Bréguet Br.121E; can anyone help please? Should I be posting this article in the Jaguar topic instead?

The article comes from the 15th June 1965 issue of Aviation Magazine International......

I didn't see them. I can read them but I don't understand them. Perhaps I'm just too Anglophone. Can someone translate them to English for me?

Hello Gents, First post on this forum (should find the introductions section and tell my life story first really!)
I'm an ex Jag engineer who is researching towards a technical book on the aircraft including its development from AST362 and ECAT specifications. I have already got some info from the national archives on Jag development and will be getting most of what I can on another trip there in two weeks (holiday booked for that one!). I am planning to include the ECAT submissions in the text plus images, so this thread is a goldmine. Can anybody help with hi res images plus info on sources so copyright usage can be sought?
Please PM me. I'll drag out the basic French ECAT specs from the AST362 files I've got and post them.. :D

Oh wow, great photo of the mockup Jemiba
Can't say I've ever seen the Dassault Cavalier proposal before.
Thanks for bringing it to my attention.
