Hopefully not like Goldfinger firing a gun in his plane.

The projectile would start at the speed of the plane and go from there.............

I'd rather have this Mach 5 for ground transport.

IIRC, the experimental flights have at best been only a second or so in duration. Never read if it was verified that the Scramjet had fired and produced thrust. It mostly crashes.

The Chinese are reading the plans for it right now.

When you think that the SR71 introduced in 1966, could fly 2200 mph, this does not sound as impressive.

Mach 5 is closer to 4,000 mph... that's nothing to sneeze at given the forces acting on the surfaces and the friction on the skin. What's unique here is that they were testing a SCRAMjet which essentially uses the shockwave of the air for super compression and then ignite. It's a RAMjet on steroids. Theoretically, it could reach speeds up to Mach 25 with enough fuel.

By contrast, the SR-71's turbo-ramjets used the cone on the front of the engine to bifurcate the shockwave and prevent it from getting inside the engine where forces would have reeked havoc on the fan blades. At speeds above Mach 3, 58% of its thrust could be from the pressure of the shockwave in the nacelles. Most of the operation of the SR-71 engines happen at subsonic air speeds.

Uninterceptable cruise missile.
It would be faster than the usual air defense SAMs (like S300 or Patriot) and AAMs.
You would need something approaching the performance of an ABM capable SAM, but those are designed for ballistic missile intercepts. This ramjet cruise missile would be a maneuvering target.

... briefly. Without a SCRAMjet of its own, it won't get far.

A better weapon would be one where we deliberately crashed the Democrat Party into the ocean.

Our very own freeper wrote the book on Hypersonics.
They called us Naspeteers.

The X-15 was rocket powered, but it got up there in speed a few times.

Recently read a book about the X and was shocked to read that they were doing SCRAM tests way back then with a test fixture mounted on the lower tail fin or whatever it is called and was jettisoned just before landing.

Ahh yes, the one and only “Powerful Mach 5”

No need. They are the party behind the stars and bars, slavery, the KKK, etc. They are responsible for for that flag and everything that went with it. They are a reminder to all of slavery and racism, so like their proposal for the battle flag, their party needs to be banned, shut down, outlawed.

A national movement to accomplish this should be promoted.

There was this sort of functional fan made model at Dragoncon back in 2011 which I think was the last one I went to.

About 3700 mph.

if circling the earth (and assuming constant supply of fuel) it’s about 6.5 hours

OTOH, The average distance to Mars is about 130 million miles. I think that’s about 4 years.

I thought the hypersonic jet ‘drop tests’ were failures.

The fastest X-15 flight really cooked; the aircraft achieved a maximum speed of 4,519mph.

LOL!! I used to watch that show!

Automan: “Green, please?” (To traffic light while driving vehicle on street)

Sensuous female voice as traffic light: “Anything for you, Automan.”

Even a failure will bring knowledge. Edison failed at making a lightbulb many times..........
