Pentagon Successfully Tests Hypersonic Flying Bomb

Fri Nov 18, 2011 4:47 pm

After the 30,000 lbs bunker buster here comes the hypersonic flying bomb. I never thought they would have bombs capable of flying at hypersonic speeds. I suppose they can also fly nuclear warheads.

They tested from Hawaii to Kwajalein atoll in the Marshall Islands - not a very big distance. How do they know the flying bomb will be just as successful flying half way around the world... let's say from the Hawaiian Islands to... Agentina (I chose a random country).

They did not say if the flying bomb reached hypersonic speed during testing.
What will they unveil next? Scalar weapons?

 Wow!

WASHINGTON — The Pentagon on Thursday held a successful test flight of a flying bomb that travels faster than the speed of sound and will give military planners the ability to strike targets anywhere in the world in less than a hour.

Launched by rocket from Hawaii at 1130 GMT, the "Advanced Hypersonic Weapon," or AHW, glided through the upper atmosphere over the Pacific "at hypersonic speed" before hitting its target on the Kwajalein atoll in the Marshall Islands, a Pentagon statement said.

For one I hope these weapons will never be used.
There was a better way to fly it was called Concorde

Your link doesn't work, but that test was in no way a "bomb" or any other weapon It wasn't even a powered vehicle. It was just a suborbital lob to check hypersonic characteristics.
And a little 2nd grade math would tell you that the "able to strike anywhere on earth withing an hour" claim that's being passed around is pretty stupid for a 6,000kmh vehicle.
ICBMs have been "hypersonic" for 50 years.

Would a maneuverable AHW with GPS capability be more accurate than a standard ballistic war head?

And since it is maneuverable, would it fare better against ballistic missile defenses?

Slower than an ICBM? Sure, but definitely faster than a B2 or a Tomahawk.

Going that fast a warhead of any type isn't necessarily necessary. Kinetic energy would be enough to destroy pretty much anything.

That's part of the challenge. Apparently hypersonic flight gets into some nonlinear effects and feedback control systems may not be fast enough to control it.

Now if we can just get the Navy's rail gun back into testing........

New high tech weapons, maybe we can share them with our friends in Israel?

Seems to work now.

Unless you have information to the contrary, the reports I'm reading suggest a maneuverable craft following a non-ballistic trajectory. Perhaps not as exciting as a powered craft, but still a notable departure from standard ICBMs.

A little second grade reading would tell you they never said the vehicle travels at that speed--just faster than this speed.  

Other sources state the goal is a 6,000km range with a time to target of less than 30 minutes and accuracy of 10 meters. How reliable those are is anyone's guess...

It will be interesting it see, if this is fielded, how exactly it would be used.

At orbital speed, it would take about 45 minutes to get from one point to its antipode. But it won't be at full speed the whole way, and it can't be doing more than low-orbit speed, or it won't come down in time. So I don't see where the 30 minute figure comes from.

It only traveled 2500 nm maybe??

Which means the average speed was 5000 knots. A longer test flight would have had a higher average speed. The average distance between any two opposite points on Earth is 10,000 nm, which means to hit any point on Earth that is opposite from the point of launch needs to have an average speed of 10,000 knots to hit that point in 1 hour after launch. Orbital speeds are around 13,500 knots or 17,000 MPH, but the weapon would not be in orbit the entire time, maybe about 40%-50% of the flight time.

What about some 10th grade geography?  

Sorry, just poking fun. If you think about all the locations where the U.S. has a permanent military presence, it's not hard to see where the one hour figure comes from. It isn't necessary for the weapon to travel from one antipode to the next. If you have launch sites at Guam, Diego Garcia, and the UK, you effectively get global coverage for the Africa-Eurasia land mass in under 1 hour flight time.

The figure below shows 3,700 nm range circles from the bases above. As 6,000 kmh is equivalent to 3,300 nm, you're most distant target would be no more than ~1 hour away.

Mach 5 is a pretty difficult feat to achieve. Especially when you consider that the shockwave starts to adhere to the surface of the airframe at and above those speeds.

Well for another one, I hope they are, and I'd even like to "suggest" a worth-while target to try it out on; ( it's somewhere in a place that starts with "I" and ends with "N" )............................

In that case, might as well gift wrap and ship them to Red China as well.
