The speed of sound depends upon air temperature, so decreases with altitude up to about 10km since temperature decreases by about 2 deg C per 1000 ft (6.5 deg C per 1000m) in that range
The speed of sound varies with altitude. At Sea Level Mach 2 = 1,522 mph
But Wikipedia would likely be talking about Mach 2 at high altitude (i.e. the only altitude at which planes can actually reach Mach 2). For example at 36,000 ft Mach 2 = 1,320 mph.
I’ve seen a similar picture of a few of them lined up, but I was unable to locate the tail numbers. So 99.99% just a mock up.
And that tail number is lifted from a Swiss F-5E
Wikipedia is a complete joke. Nowadays anyone can edit it.
Its purposed.
Not a mockup, it’s a purposed plan so its concept art of what could be one of Switzerland’s future jet fighters.
This is not true- the referendum to purchase Gripens failed. They do not and have never had gripens, they decided to procure F-35 to succeed their F-18s.

Switzerland Trialed them, their military wanted to buy them but the public vote denied it
a few years later they bought F-35
Sorry to tell ya but I wouldn’t count on getting a gripen e as an event vehicle.
That’s not even a JAS 39E in the photo, let alone a Swiss one
Anyway. Here’s the same stock image mocked up as a Bulgarian Gripen
and an Indian one

Mock ups can be concept art, doesn’t have to be something physical.
“A model or replica of a machine or structure, used for instructional or experimental purposes.”
Mock-ups and Concept art are not interchangeable words. Concept Art is an artistic envision. a mockup is a physical interpretation of what it will look like.
HOWEVER, Mock-up Art is the word you’re looking for. This word takes what exists in the real world and puts it under different themes such as another nation’s colors, what it may have looked like if it was abandoned so on and so on.
So there is some truth but man English is a pain and that’s coming from a native speaker of it.
Do y’all think a Swiss JAS-39 would be a good event vehicle?
Photo shoted?
The gripen c was actively trialed as an replacement option, which is more likely then the gripen e
It didn’t exist, so no. On top of that, Switzerland doesn’t even have a Subtree anywhere (yet) so there’s no place for it to go anyway.

“hey guys, should they add Swiss Gripen as event vehicle?”

No, it was always the E that was intended as the replacement for the Tiger II. At the time evaluation began however, only C airframes and C’s with adaptations leading to E were airworthy though. This was one of the reason the Gripen had such a hard stand in the view of the Swiss voting population, as left media kept repeating the Gripen E is just a paper plane, carefully ommitting each of the milestones of the very successful and in-time development and testing of the Gripen E at the same time Switzerland prepared for the vote.
Stil a very emmotional topic for me. We fought hard, and failed. That was a sad sad 18th of May. I remember it vividly, even though it’s already ten years ago…

switzerland still trialed the gripen c already during that time period and the pilots were actively trained on the gripen c for over a year Schweiz - Gripen: Drei Schweizer Piloten trainieren in Schweden - News - SRF

Yes the pilots trained on Gripen C’s, but the C’s were never intended as the new fighter plane, is what I was trying to say.
Btw had the chance to get to know both the project leader as well as the chief test pilot who was in Sweden for those trials. Had some very interesting talks with them. Too bad their voices were not properly heard by the public…
