If we miss the missile with the ABM interceptors it would be an embarrassment, but if we miss it with the Boeing (Deathstar) 747 know one would ever know we tried. I assume that the North Koreans are not stupid enough to throw it in our direction, so I don't know how the ABMs are supposed to intercept it anyway. Is there a chance, assuming our ABM system actually works, of intercepting the NK missile in a trajectory not aimed at the US westcoast, or is this a fantasy of the Newsmedia? I think the most likely mode of interception is a boost-phase intercept by the Navy missile cruiser that is presently sailing off of the North Korean coast using its upgraded Standard Missile-3 system. The Navy has recently done successful ABM tests of this system against target missiles: http://www.defensetech.org/archives/001409.html Unless North Korea fired the missile at the United States itself (which would be insane, but these aren't the most rational people in the world) I doubt that the missile would ever come in range of our land-based ABMs. As for the 747 ABL system, the little I've heard of it recently seems to suggest that it is moving forward at a snail's pace, and may be a target for cancellation. Pat SM-3 has no capability inside the atmosphere and by the time an ICBM is in space it's probably going too fast. That SM-2 Block IV they tested a few weeks ago might be just the ticket though ;-) |

It's most likely military opponent is either China or North Korea, and neither of those are far enough away to require the sort of range this three-stage rocket would have in a ICBM role. We, on the other hand, are that far away. Are they getting edgy about U.S. interference in their oil supply again, like happened in 1941? Pat |

Check out this BTW: http://www.defensetech.org/archives/002317.html .....and this, about the cool-down time after it fires: http://www.defensetech.org/archives/001554.html That's a major problem; salvo launched missiles will get past anything other than a fleet of ABLs using this type of technology. Here's what happened to the program: http://www.defensetech.org/archives/002176.html Pat |

Some parts of China would be 3000 miles away and Japan's 1st nukes wouldn't necessarily be W-88s right out of the box even with their technology base. Also it would allow them to use conventional warheads or drop a stage off and just use two stages. A 3 stage space launcher and a two stage ballistic missile. |

Pat With the exception of the last couple no-shows (yeah I know) it was actually starting to do pretty good. The one that seems to be working very well is the Standard Missile-3 Navy system. The ABL on the other hand....Boeing has even removed the webpage devoted to it. It looks like it will join the atomic-powered airplane, Copper Canyon TAV bomber, and X-33 SSTO demonstrator in the "what _were_ they thinking?" pile of discarded projects that cost a bundle and produced zip, due to a fundamental flaw in their design conception. Pat Last I heard ABL is still going strong. http://www.missilethreat.com/systems/abl_usa.html At worst I think what might happen is the numbers get scaled back simply because of the advances in solidstate lasers. Many of the problems that need to be solved are independant of the type of laser you're using so it would be quite a waste of money to cancel it. At the very least I'd think they'd use it to work out all the kinks of putting energy on the target and giving an "emergency capability". Maybe two or three in service instead of the seven or so they'd originally planned. Then when they switch to solidstate lasers down the road they could just use the 787 or 777 or something. Use an F135 (no afterburner necessary :-) ) to drive two counter-rotating flywheels on the CG so you can tap a LARGE amount of power in a hurry. .. . maybe that's overkill. Not the flywheels but maybe you don't need THAT much shp driving them if you have a bit to spool them up. |

The Chinese would be expecting them to attack with boosted fission warheads. They wouldn't be expecting anything else regarding Japan's abrogation of the development of "nuclear weapons" in regards to bombs. Except for of course NUCLEAR HEAT CANNONS bounced off the ionosphere! Remember how we didn't see the coming German rocket threat when the Treaty Of Versailles was negotiated in 1918? Big battleships out; big artillery out. Not a mention of big rockets being out. THEY CAN FIGHT MOTHRA AND THE MYSTERIANS; THEY CAN FIGHT BEIJING! ;-) Pat |
