Satellite Shoot-Down Is Warning to Iran
Hey, we got some bang for our bucks ($30,000,000 estimated). First, we don’t have one massive satellite smashing through our roof – now, we’ve got lots of little fragments that can hit more houses, but do less damage; Secondly, we don’t have that deadly hydrazine fuel in one big, toxic lump – we’ve got it dispersed all over the place, leaching slowly into our atmosphere (I’m sure the global climate change and chem-trail fanatics will jump on that bandwagon); Thirdly, the Generals over at the Puzzle Palace don’t have to stay up at night wondering if some geek might find the darn thing and sell it on e-bay – exposing classified equipment; And, finally, we have the following train of thought sent in to us by Warner:
Satellite shoot-down is a clear warning to Iran
James Lewis – American Thinker
Wednesday night’s SM-3 shoot-down of a US spy satellite tumbling out of its orbit was a magnificent success for anti-missile defense. It meant hitting a bullet with a bullet, with only a ten-second time window for the shot. The hit was kinetic, meaning that there was no conventional warhead to explode, and the SM-3 hit the fuel tank of the bus-sized spy satellite right in the sweet spot in order to disperse the toxic propellant. The small pieces left over will now burn up in the atmosphere.
The SM-3 was traveling at 17,000 miles per hour when it hit the spy sat. The target was “cold,” so that heat-seeking sensors designed to locate hot missiles were not even used. This was a last-minute modification of an anti-missile system for a special job, an extraordinary technical achievement, and one that is now sending ripple effects all around the world. The Chinese People’s Army and the Russkis are all upset, poor babies. But this fast, off-the-shelf demonstration of US technical prowess was really a direct shot across the bows of Iran — and also North Korea.
Why? Because the Russians and Chinese have had ICBMs for decades and never used them. They respond to the balance of terror in a rational way. But Iran and North Korea are constantly threatening us, unpredictable, and often crazy-sounding.
Just this week we heard official statements like this:
“The cancerous growth Israel will soon disappear… I am convinced that with every passing day Hizbullah’s might is increasing and in the near future, we will witness the disappearance of this cancerous growth Israel by means of the Hizbullah fighters’ radiation [therapy].”
Well, “Hizbullah” means “party of Allah,” and that refers to the whole Khomeini cult, not just its Lebanese lapdog. So “radiation therapy” from the Party of Allah has a pretty clear meaning. Tehran’s head guru, Ayatollah Khamenei, also explained that Allah hates any Iranians who don’t support the nuke program. Exactly where he found that in the Koran wasn’t explained.
Meanwhile, North Korea is in the middle of a succession struggle, always the trickiest time in family despotisms. The Syrians, too, have been getting NoKo help on nuclear power, according to Israeli sources.
The Iranian opposition group that keeps leaking the mullah’s nuke secrets has just presented evidence that they really do have a working factory to make nuclear warheads, at a town called Khojir, built in cooperation with the North Koreans. Since fabricating ing a nuclear warhead is not difficult once you have the uranium or plutonium, this sounds believable. That news knocks the last leg out from under the rickety fantasy world of the last US National Intelligence Estimate.
So this is a crucial time to demonstrate to the rogues that the West can defend itself. That is why the administration chose this time to show off our anti-missile defense capability.
The brilliance of our anti-missile systems is that they can move and fast and stealthily from place to place. Aegis cruisers like the one that just shot down the spy satellite can be sent to any navigable sea in the world, very close to North Korea, Iran, and Syria. If Chavez ever buys missiles from his friends in Tehran, or if Castro’s successor does, the US Navy can be in range the next day. Once we get laser weapons mounted on aircraft, we will have even faster and more flexible defenses. That technology is not far away.
So this is an historic moment for the good guys. For the first time since Stalin exploded an atom bomb in 1949 there is a working defense against nuke-bearing missiles and planes. Real civilizations — large cities surrounded by farms to feed them — have always depended upon walls, moats, and natural defenses. That is the only reason why we have the prosperity and culture that began with Sumer 6,000 years ago. But defense and aggression are always in a race — the liberal fantasy that arms races are somehow abnormal in history is just ignorant.
What’s different about the last half century is that city-killing weapons have put the aggressor at a major advantage, so that a High Noon standoff was the only answer. That horrific period is now passing as missile defenses come into their own. We are coming back to a more normal balance. That is a very good thing.
So when you vote in the Fall, don’t forget who made missile defenses possible.
(Hint: It wasn’t the Democrats).

God bless Ronald Reagan-looks like his “nutty” Star Wars idea was a great one after all.

IFL,
Amen to that, brother!

Dr., how fast would an Iraian ICBM travel, as apposed to a Satellite being shot down?
I understood the shot taken was 22000 miles an hour closing distance. Would it be the same for an ICBM?

With the number of Aegis CG-47 Class Cruisers equipped with BMD (BallisticMissileDefense) technology loitering in the Persian Gulf, it’s unlikely that any Iranian ICBM would get out of first gear before being neutralised.
I strongly suspect that the top secret ‘refuelling station’ Diego Garcia in the Indian Ocean is bristling like a porcupine with similar kit.

Leatherneck,
It depends on which phase of the flight the ICBM is in.
Pre Launch
Launch/Boost Phase – lasts about 300 seconds
Midcourse phase (Apogee is reached here) – average time is about 20 minutes
Terminal phase (Re-entry) – about 40 – 60 seconds to impact
At pre Launch phase, it’s obviously at 0 mph. (That’s when I prefer to hit them… – less chance of missing…)
At Launch/Boost phase, the ICBM accelerates from 0 mph to up to somewhere well below about 25,056 mph (escape velocity of the Earth) in about 300 seconds.
WARNING: Rocket science content here: Because the ICBM is NOT trying to escape the gravitational pull of the earth, it will be less than this speed (25,056 mph) so that it can drop back down to the Earth. Think of it as a baseball, the harder you throw it at a consistent 45 degree angle, the farther it will go. Obviously, if you want it to land somewhere on the Earth, you will want to keep its velocity somewhere below the escape velocity of the Earth, else it will hit Moon, or Mars, or something else that might start an intergalactic war… Also, burn time is important, as a baseball doesn’t carry its own fuel, but a rocket does, and as long as the rocket is burning fuel with enough thrust to counteract the pull of gravity, it will keep on going even if it’s velocity is below the escape velocity of the Earth’s gravity well, unlike your baseball which can’t keep accelerating, so it slows down, reaches its apogee (farthest point away from the Earth in its arc), then it accelerates back towards earth due to gravity…)
So, to make a longer story short, we can deduce that the ICBM will be traveling at a speed less than the escape velocity of the Earth (25,056 mph) at the end of the Launch/Boost stage. Most ICBM’s (that I’ve seen) achieve a top speed of about 15,000 mph during this phase.
Now, since the Boost stage is so short (about 5 minutes), and because the ICBM is accelerating during this phase, it’s too difficult to shoot it down. So, we wait for the Midcourse phase to shoot it down.
The Midcourse phase is just the phase where the ICBM’s engines cut off and the ICBM kind of just coasts in a slow arc to apogee (midway point) , and then begins to fall back to Earth (I’ve heard rumors that some have been designed to have an irregular flight path and pulsed thrust from the engines to help it evade Star Wars technology, but those are rare birds… )
The Midcourse phase is the longest phase, and is where you would want to shoot down the ICBM, especially if you could hit it at its apogee point, as that’s when it is at its slowest speed (remember the baseball analogy). I’m sure it’s still going pretty damn fast at apogee, since it’s in a looooong arc, but it will still be below 15,000 mph…
The Terminal/Re-entry phase is where the ICBM re-enters the atmosphere at about 15,000 mph and then slams into the earth. Since the ICBM is now traveling again at about 15,000 mph when it hits the atmosphere, (due to gravity giving back some energy that was lost at apogee) and since it only takes about 40 seconds for the ICBM to slam into the Earth from the time it hits the atmosphere, this is one of the worst times (except for the launch/boost stage) to shoot down an ICBM, but this is when they are most likely to be detected, and it can be done…
So, the answer to your question is that if we can shoot down a satellite traveling at 22,000 mph, we can definitely shoot down an ICBM traveling at 15,000 mph…
Cheers

That’s what I was hoping to read. Thank you.
Apogee. Apogee. Got it.
