I'm wondering, with the LTV A-7 and Dassault Milan together, what nationality air force trial might have been occuring here?🤔

Switzerland - In 1972 the choice for a new fighter was between the Milan and the A-7G Corsair II.  Eventually neither was selected and instead the Swiss Air Force purchased 30 additional, surplus Hawker Hunters in 1973.

Thanks for your response and clarification Greg 👍

Sorry - this is probably a daft question, but -

If the Boeing-Dassault proposal for the F-5A Freedom Fighter had been built based on the Mirage 5, would it have had an unreheated engine and not need the intake cones? That would leave the reheated Atar or J-79 engine in the F-5E. Hope this makes sense.

I don't think there was ever a proposal for a unrelated engine version....

No I suspect they were proposed with the Atars. But cannot find real info. I did make a few with standard intakes and exhausts years back, but I have been looking back at some of Spinners artworks where he proposed an unreheated Spey. Have not checked if it will even fit to be honest, but the model I am using has really poor definition so trimed the intake cones off and changed the exhaust. So it looks like the artwork - I suspect I am simply over thinking this with a vengence
Actually the Spey is too wide - I suspect the J-73 would be the way to go

Well the first Mirage III 001 prototype didn't have the inlet cones/souris.  On September 19, on its 78th sortie, Mirage III 01 reached Mach 1.8 in level flight using its ancillary rocket and then, some two weeks later on October 2 (flight 84), Mach 1.89. The aircraft had reached its upper limit: its air intakes prevented any further increase in speed. It still had reheated Atar though.
