France to deploy fighter jets with nuclear warheads on German border

#France will deploy #Rafale fighter jets with #supersonic #nuclear #warheads along its border with #Germany in 2035

The move comes as the U.S. shifts its focus away from Europe and Ukraine, signaling that the continent may not be able to rely on Washington for its future security.

#Supersonic #planes are inching toward takeoff. That could be a problem.
Boom estimates that one of its full-sized Overture jets will burn two to three times as much fuel per passenger as a subsonic plane’s first-class cabin. Compared to standard economy-class travel, first-class cabins tend to have larger seats with more space between them. Because there are fewer seats, more fuel is required per passenger, and therefore more #emissions are produced for each person.

‘Even the F-22, developed almost 50 years after the Concorde and the reigning undisputed air supremacy fighter can only supercruise at Mach 1.8 and its top speed – Mach 2.2 – is the same as for a Tornado. If Concorde was still flying, it is unlikely it would be able to photograph it at Mach 2.0. Even if the Soviets back at the time were willing to lend the Mig-25/Mig-31, it is not entirely clear if it would be able to sustain the level flight with Concorde at Mach 2.0 for long enough to have a picture taken.’

An Exoplanet’s Supersonic Jet Stream

WASP-127b is a hot Jupiter-type exoplanet located about 520 light-years from us. A new study of the planet’s atmosphere reveals a supersonic jet stream whipping around its equatorial region at 9 kilometers per second. For comparison, our Solar System’s fastest winds, on Neptune, are a comparatively paltry 0.5 kilometers per second. The team estimates the speed of sound — which depends on temperature and the atmosphere’s chemical make-up — on WASP-127b as about 3 kilometers per second, far below the measured wind speed. The planet’s poles, in contrast, are much colder and have far lower wind speeds.

Of course, these measurements can only give us a snapshot of what the exoplanet’s atmosphere is like; we don’t have altitude data, for example, to see how the wind speed varies with height. Nevertheless, it shows that exoplanets beyond our planetary system can have some unimaginably wild weather. (Video and image credit: ESO/L. Calçada; research credit: L. Nortmann et al.; via Gizmodo)

"Boomless Cruise: How Boom Supersonic’s XB-1 breaks the sound barrier quietly" by AeroTime - #XB1 test flight had sensors monitoring on the ground which confirmed no sonic boom reached the ground during three times it exceeded Mach 1. Using subsonic speed longer for climb, they reached Mach 1+ above the altitude where booms refract back up before reaching the ground. A nice new trick for potential #supersonic air #travel over land. aerotime.aero/articles/boom-su #aviation #avgeek

Man könnte sagen, der Name ist Programm. Boom Supersonic heißt ein Startup aus Colorado, das die Luftfahrt revolutionieren will – und zwar mit einem lauten, aber nicht zu lauten Knall ;)

I’ve been following “Boom Supersonic” and “Tokamak Energy” on the internet for years now, and it’s great to see the breakthrough from Boom today. Hopefully Overture will be a lot nearer, and supersonic passenger flights will soon be flying again!
