Cool.

[Excuse_My_Bellicosity]

Ping!!

DoD seems to have discovered the V1 buzbomb.

DoD seems to have discovered the V1 buzbomb

At Mach 6 it would have crossed the distance from England to Germany in a few minutes and left NO warning.

Way to go DOD .... now make a decent missile of it.

[patton]

The speed is impressive, but I think that they were flying in the other direction...

[Teacher317]

The SR-71 Blackbird record is just over Mach 3... Mach 6.5 mean it could catch up to a Blackbird going all-out at a closing speed of Mach 3+... Dang, that's fast!

[Bogey78O]

This suckers a lot faster than the V1

[Bogey78O]

Maybe we could make an Air to Ground launched missile that's firable from the SR-71.

Who needs stealth when you can outfly anything the nenemy can shoot at you.

"Quantity has a quality all it's own..."...Churchill, I think.

[Teacher317]

IIRC, one of the SR-71's first problems was the possibility of out-running it's ordnance.
This puppy would've solved that little dilemma.

and a Mach 3.2 platform pushing a Mach 6.5 missile would certainly give little advanced warning!

(Ahh, can't you just feel the testosterone flowing with these numbers floating around?)

I would love to see that weapon developed. Give it a low yield nuke for a warhead and there is no missile defense system that could stop an attack. It'd be a deadly trump card.

Having worked for DOD support companies (Lear Siegler and Qualitron-Aero) in the past, I have been told by people who should know that the SR-71's top speed is much higher than Mach 3.

Supposedly every time the Russians or someone else would set a new record, they would fly the SR-71 just fast enough to set a new record.

I have also heard that they don't really know the absolute top speed. That because of the fact that the engines generate more power the faster they go, that they think the SR-71 would just go faster and faster until something breaks, melts, or blows up.

[Loc123]

Didn't the Russians develop an ICBM that can travel extremely fast? IIRC that why they aren't afraid of our developing missile defense system. Anyway, good going DoD R&D!

God bless Kelly's SkunkWorks!

The SR71 had flameout problems that were cured by continously injecting pyrophoric liquid into the combustors during flight. That was the stuff that always used to leak out of them on the ground and burst into flame as it came in contact with the air.

In flight at Mach 3 and above the effective viscosity of air is like that of 30 weight motor oil. Not only is it hard to get it to flow through the engines and around the aircraft, but a flame out can decelerate the aircraft so hard that the pilots are turned into mush.

Burning kerosense in a scamjet is no small feat either. Unlike Hydrogen is has a relatively slow flame speed and can easily be self extinguished by a small change in mixture ratio.

If they have really done it then, Bravo. It took generations of research to get there.

I don’t know about the SR-71… My uncle was an air traffic controller in/around Reno. I don’t know exactly where, but he lived in Sparks at the time. He said the Air Force would routinely tell them they were flying planes through their area and to ignore them. He said you could mark their positions on the screen with a grease pencil as they flew through and then measure the distance traveled each sweep to approximate speed. I don’t remember exact numbers for exact planes, but I remember they (according to him) were flying much faster than what the Air Force admitted to…

True ...

We rock.
