Sorry to say I'm holding my breath on this one

Wasn’t that the one that was slung under the belly of an F-15? I heard that worked pretty well.

It seems that, if done right, a successful intercept could ensure it lands in the ocean rather than on enemy soil. True. If you hit it head-on over the south Pacific, I think a lot of the chunks would end up deorbiting right there.

These "small pieces" will establish their own orbits, creating a nightmare for other orbiting bodies (like commercial communitication satellites.) What will be the altitude of intercept? Very low -- within a few days of the actual entry, so the chunks will probably decay pretty quickly.

Wikipedia:
Cascade Effect
Cascade effects seen in the perspective of space travelling are theoretical possibilities that "space junk" or a satellite destroyed by a meteor will send debris throughout the orbits of most telecommunication satellites destroying them in the process and subsequently sending that debris into all possible orbits, destroying everything in orbit around the earth. It is theorized if this occurs, space flight beyond Earth will become very difficult if not impossible.
Ummm...Let's hope these guys know what they're doing.

Commercial communications satellites are far, far higher.
There is virtually NO chance that the pieces of this will get any where near such satellites.

You’re wrong. This intercept will probably be at lower than 80nm... far below “astros in LEO”

The reason it survives is that there is a whole lot of space in Space... lots more than you apparently believe there is.

Stupidest idea ever. Lets just create the largest debris hazard we can for our astros in LEO, and then confine us to this planet.
Man, whoever decided to put politicians in charge of anything more complicated than a matchstick needs to be tarred and feathered...at the very least.
No, no, no! They are waiting until USA-193 is very low, below operational LEO height, precisely so other satellites aren't damaged by the debris field of the destruction of USA-193! With the debris field so low, it will decay shortly and more completely than if the satellite is left alone! Think man!

Save money and hire the Chicoms to zap it to pieces.

Is another purpose for this to prevent the imaging equipment from falling into enemy hands? Reminds me of Ice Station Zebra.

“With the debris field so low, it will decay shortly and more completely” if you go to the link in post 17, china’s debris was still in space 11 months later. How short is shortly?

Doesn’t matter, they’re creating a debris hazard. It’s a stupid idea. You have to go THROUGH that altitude to get up and down.

"These "small pieces" will establish their own orbits, creating a nightmare for other orbiting bodies (like commercial communitication satellites.) What will be the altitude of intercept?" From the story:
"He said a Navy missile known as Standard Missile 3 would be fired in an attempt to intercept the satellite just prior to it re-entering Earth's atmosphere. "
If the dead satellite is hit just before re-entry, it is very unlikely that the impact will add any orbital energy to the pieces. They will all come down, and be more likely to burn up at high altitude. The Chinese ASAT test was at higher altitude, and most of those fragments are still orbiting.

That’s a damn lie. It’s better to leave it intact and let it burn up. Atmospheric heating during reentry is all about mass/surface area ratio. The frictional heating will be much higher on the intact satellite than on the individual pieces. They’re creating more a hazard to people on the ground and in LEO by doing this.
