When the Navy made Great Lakes port calls as they did every few years, all kinds of treaty work was needed first. When the USS Cod was brought to Cleveland; the batteries were removed, the space filled with concrete, and various other "demil" changes were made. I know we made a lot of subs during WW II, but frankly, trying to name them all after fish was a dumb move, because then you end up with things like USS Cod. I'll bet that made the Japanese shake in terror...you have battleships named after the greatest Zen swordsman of all time and volcanoes, and your opponent has a sub named after the fillet on the budget seafood platter. Still, it beats the British "Flower" class corvettes. Can you imagine having to explain to your children your service aboard the HMS Buttercup? :-) http://en.wikipedia.org/wiki/Flower_class_corvette The Japanese sci-fi anime series "The Irresponsible Captain Tyler" had a lot of fun with this...Japanese WWII destroyers were traditionally named after violent winds...his space destroyer's name translates as "Gentle Breeze". :-D Pat |

Nowadaze, any sub would soon fall victim to the zebra mussels.. Not if they electrify the hull to repel the mussels. This works on big mollusks; it should work on small mollusks as well. If that fails, it's time to surface at night during a storm and fight them muscle-to-mussel with ball-peen hammers. Nemo |

wrote: I may have seen a underground fallout shelter in Moscow as well... a large grass-covered field surrounded by a fence, with multiple ventilators projecting from the field and a raised bump at one edge with a heavy door in it. I never got inside of this, so don't know the details of its interior, or even if it definitely was a fallout shelter. Since you've seen them, perhaps you can help with estimates of the shelter area that might exist underground. I have come up with at least 120 km of tunnel for the Moscow Subway (total system length is 292 km, but not all of this is underground tunnel). If it is a 4 track tunnel similar to the NY Subway It's been a long time, but I _think_ it is only two tracks. then the tunnel width would be ~16 meters. It's a lot smaller in diameter than that Around ten meters tops, and probably not even that. There must be a lot of info on it out on the web. The Metro stations are really spectacular and very large in cubic metric area though. The system seems nicely sized for passenger demand also, as every time I rode it the cars were around 1/2 to 2/3rds full. Maybe they fill up more in summer (I was their for Christmas/New Years). The Leningrad system was virtually identical to the Moscow one as far as design goes, as both were built at around the same time (1930's), by Stalin's orders and using a huge work crew of young Komsomol members, many of whom died from cave-ins and freezing in winter*. 16*120,000= 2,000,000 m^2. There are 10.5 million Moscovites Long time back, Robert A. Heinlein visited Moscow and said he thought the city's population was way overstated by the Soviets, based on the amount of road, river, and rail access to the city versus what would be needed to supply that many people with food. Although the city is big in area, and the per-apartment population averages around 5-7 as far as I could see (mom, dad, two kids, and at least one grandparent) once you get outside of the center of the city, it sure doesn't seem very crowded as far as people walking on the street goes. It reminded me of Minneapolis more than say, New York or Chicago. so 5 people per square meter if evenly distributed, or half that if there is in fact 240 km of tunnel (which I doubt). Even at 2.6 people per square meter that is pretty tightly packed throughout the entire system. My analysis of the damage a boomer of two could do to Russia was a quick and dirty way to get a first order assessment of the magnitude, and generally gives the cities a favorable break by assuming a homogeneous distribution across the official city area. Any more "clumpy" distribution of urbanization increases the density to be targeted, and in the subway shelter situation crams more people into less shelter. The Metro is such a cheap and officiant way of getting around (you entered it via a 5 kopeck coin - oversized just for that use; it was bigger than a US quarter, and the official exchange rate would have made it worth around 8 cents - and could keep riding around in the Metro system for as long as you wanted till you finally exited a station) that it pretty much eliminated all other forms of transport other than quite a few buses and a very few cars. It would further more be necessary to fill up the entire system in the 20 minute flight time from the missile launch. The average distance between stations is 1.6 km, so one would be looking at a ~2 km walk to get to a station and then file deep into the tunnel. Depends on where you were; although the distance between the stations seems great when averaged in that way, the great growth of the city after the Metro was built meant that new construction of housing tended to cluster around the entrances to the Metro. I spent a whole afternoon zipping around Leningrad via Metro and foot (including going 180 degrees opposite of the direction I intended to on the way back to our hotel because I can't read Cyrillic; this took me up near the naval yards, and when I realized where I was I got out of there ASAP). And each station would have to get an average of 60,000 people through the doors (assuming all 177 stations are suitable tunnel entrances). The escalators can transport a very large number of people into and out of the subterranean stations, and you are allowed to walk as you ascend and descend them if you want to get up or down faster. The problem would be the complete panic that would ensue if you had a actual "Shelter On Warning" situation, as you state. If the tubes are only ~half the width of what I proposed and the population substantially more concentrated, then it would seem impossible to simply fit them all into the tunnels. The higher density areas have shorter walks on average, but then the problems with packing them in through the entrance stations become even more severe. As capacious as the entrances and stations might be, getting a couple of hundred thousand people inside within minutes seems unlikely. I just looked up some stadium evacuation studies. One using University of Pennsylvania‘s Franklin Field found that it took 16 minutes to evacuate 19,000 people from the 52,600 person stadium. Another had it at more than an hour to empty a stadium under disorderly conditions. Getting centrally located people out of a single structure though the multiple vomitoria is much easier than packing distributed people in through one entrance. So I suspect getting a significant fraction of people into the subways under a shelter-on-launch-warning scenario is simply impossible. The effort would probably increase the exposure of the population by having them queued up outside without any protection. How many people could actually get to shelter before the nuclear flash photography starts? Crowds thronging the streets, streaming to the tunnels when the warheads arrive would vanish down to the last man and woman. One thing is for sure...if the Soviets ever ordered everyone to head for the Metro ASAP in peacetime, it would mean that they thought WW III was going to start inside of a few hours, either by their actions or someone else's. Well, the scenario under consideration started with the Soviets/Russians launching a disarming strike on the U.S. so WW III is already in progress. The necessity of having to use shelter-on-warning is due to the fact that the time of retaliation is at the discretion of the submarine and can be launched many days after the initial attack. Then afterward the city, converted into kindling, would burn in the largest mass fire the world has ever seen. Actually, I don't how much would burn... Moscow is the biggest collection of rock, metal, and cast concrete you ever laid eyes on**. Anything made of wood after around 1945 is rare to see, and as far as the apartment furnishings go, a lot of what we would make out of plastic or wood, they made out of stamped or welded metal. Cities in general are more combustible than you would probably think - the interior of buildings are quite combustible (no wood furniture or fabrics?, paper?), fuel is stored in many locations, and wood framing is more widely used than is evident. The firestorm area in Hamburg was built of brick. The presumed fallout shelter I saw stuck out like a sore thumb as it was an area around a block in size that had _nothing built on it_, and in Moscow, building space is always at a premium. "Do we want to put a tree here, or add another apartment?" "**** the tree. The tree is a social parasite on the city's water supply and a invitation to hooliganism among our youth. Besides, there are already over 100 trees in Moscow." Even being sheltered in a tunnel might not save them (people perished en masse in bomb shelters in Hamburg and Dresden from carbon monoxide poisoning, before their corpses cooked). I got the feeling that the whole civil defense system was more a Potemkin Village than a a workable system in time of nuclear war, just put there to show the government actually had some concern for the populace. Right. I got that from Russian emigres as well, who felt it was a joke. Still... beats digging a hole in the yard and throwing a door over it, as Reagan's advisers suggested. There was an extreme disconnect between what would really be necessary to shelter a population during a nuclear war, and claims of "cheap and easy" from CD proponents. There was some basis of some of the claims, e.g. being anywhere below ground is better than anywhere above ground, simple expedient shielding can protect effectively against thermal and ionizing radiation, etc., but blast protection is really hard and costly, the difficulty of actually implementing expedients in real crisis situations for the whole population is formidable, and the whole scheme suffers from the weakest link problem: one can forestall disaster, but in the end disaster catches up anyway since all of the catastrophic problems of nuclear war must be dealt with, not just some of them. |

My uncle used to be civil defense chief for our town, and had a full fallout shelter in his house basement; there were a few other ones located in the town as well, but nowhere near enough to shelter the population of 15,000, particularly due to the fact that our latitude of around 45 degrees north meant that we were sitting under a worldwide fallout belt because of all the military targets that are in that latitude. One oddity is the new court house/jail that was built here in the 1980s. They had a tour of it when it opened, and I noticed that the basement was way overbuilt for the weight of the building, and all the plumbing in it had accordion joints on it. The reason is that the whole basement is a fallout/blast shelter, and it was the intention to move the whole North Dakota government into it in time of nuclear war, as it had something like 90 days worth of food and water stored in it, as well as diesel generators to provide power for it. Why you would go to all that trouble and then publicly announce that use for it is beyond me, as all they accomplished was making it, and our town, another potential target for nuclear attack. Pat |

Yesterday's mediocrity is today's inspired new idea. I do have to admit that they turned Battlestar Galactica into something pretty good, but Limpet is asking a lot. Still, you wouldn't think you could make a mermaid movie half as good as "Splash" either. Pat |
