Why should a carrier radar be so distinctive at long range? The only thing it needs it for is to support carrier landings, and that could in principle be done at very low power. If you are talking about the long-range air defense for the carrier (e.g., AEGIS), I can understand that, but that's a different question unrelated to carrier operations per se. ------------------------------ Date: 23 Feb 1986 19:02:40 PST From: Jerry Mungle <JMUNGLE@USC-ISIF.ARPA> Subject: Re: Arms-Discussion Digest V6 #51 Regarding the message from ucsbcsl!uncle@ucbvax.berkeley.edu on the McNeil-Lehrer interview -- I found the use of a pseudo-southern dialect in the text completely unnecessary and highly offensive. The point was clear from the text of the message, it was clear the use of alternate spelling was an attempt to ridicule based on regional bias (perhaps unintention, but still offensive). Let's stick to the facts, please, and leave the 'cute' displays out. It reflects poorly upon your position to resort to such devices. ------------------------------ Date: Mon, 24 Feb 86 18:34:50 EST From: ihnp4!utzoo!henry@seismo.CSS.GOV Subject: Galileo plutonium Timothy Wright writes, in part: > I read in the latest issue of The Nation that one of the shuttle's > planned missions included the Galileo-Jupiter probe, which would have had on > board about 46 pounds of Plutonium.

It didn't vaporize or pulverize the rest of the Challenger, just broke it into small pieces for the most part. The interior of the cargo bay is probably the best-protected area on the shuttle, too.

Depressed-trajectory ballistic missiles still leave the atmosphere, they just don't get as high. One cannot get ballistic-missile speeds within the atmosphere for more than a very brief period with current technology! Pershing II, Trident D5, Midgetman will all spend most of their trajectory in space. Cruise missiles don't, but they don't have the speed and altitude characteristics that make ballistic-missile interception such a difficult problem. > ...Then there are the problems of ASATs, > gravity bombs, nuclear artillery and land mines, and the chance of a > suitcase-style bomb. These weapons will compromise any space-based system. Different weapons need different defenses. Survivability of an anti-ICBM system against ASATs is definitely an issue. Gravity bombs and nuclear artillery can be handled with existing defence technology (although said technology sometimes is not embodied in operational systems, partly because the overwhelming presence of un-interceptable ballistic missiles reduces the incentive). Land mines are not an offensive weapon. Suitcase bombs are an issue but not necessarily an unsolvable problem. Nobody said that space-based systems would solve all the problems, just that they would solve the big one that other systems can't.
