JFK's greatest achievements/Apollo (Was: Deep Apologies to everyone....)
Derek Lyons wrote: It would be a bit long to explain his work on the Soviet submarine-launched "Shaddock" cruise missile series, but the overall concept and operational details of the system went past the U.S. Navy's Regulus I/II system of the 1950's like it was something out of WW II. Apples and oranges - Shaddock and Regulus operated in different enviroments against different sets of targets. It's not clear they can be usefully compared. There was a inertially-guided land attack version of Shaddock that would have performed the same function as the Regulus 1 and 2. Chelomei's big breakthrough was in how to store the missiles on the sub. With the US concept, the missile was either carried folded in a hanger on deck, or in a internal hanger. In either case, the missile had to be moved out onto a deck launcher for liftoff, and the crew in the case of the internal hanger was expected to check out and do maintenance on the missiles during the cruise. Chelomei came to the conclusion that the crew messing around with the missiles could cause more harm than good, and after a Whiskey class sub carrying a Shaddock in a deck hanger had the hanger flood and the sub capsize, that there had to be a better way to do this. His solution was to incorporate sealed launch tubes into the secondary hull of the sub. These were inaccessible to the crew in normal operations, and their interiors were both humidity and temperature controlled to keep the missiles in pristine condition. No internal hanger in the sub cleared up a lot of space for other uses, and prevented possible flooding when the missiles were being brought out to the deck launcher in rough seas... a very real concern on the the US subs that used the internal hangers. Rather than having to deploy the missiles to the launchers, you could simply elevate the launch tubes and let the missiles fly. The other big innovation was in how the missiles were guided... when the target was only thirty or forty miles away, the radar in the missile's nose scanned the sea ahead of it and transmitted the image back to the sub, where a targeting officer aboard the sub chose which of the targets on the screen (the aircraft carrier) to attack, and commanded the missile to lock onto it. At longer ranges where the missile passed under the horizon from the sub's viewpoint guidance could be linked to the sub (or directly taken over) by either a Bear bomber or Hormone helicopter positioned between the launch point and the target. There were three different missiles referred to as "Shaddock" BTW, here's info on them: http://en.wikipedia.org/wiki/P-5_Pyatyorka Here's a Echo II class sub launching a P-6 missile: http://en.wikipedia.org/wiki/File:Ec...ile_Launch.jpg It carries three pairs of these; one pair ahead of the sail and two astern of it. Either this is a inertially guided version, or the big guidance antenna mounted in the front of the sail isn't rotated into position until after launch to prevent it being damaged by the missile's backblast on liftoff: http://www.globalsecurity.org/milita...ages/pl659.jpg (part of that one's antenna has been removed, but it does give you a idea of the thing's size and how of the front of the sail rotates 180 degrees to expose it.)

You are really talking about time and volume of the traffic which you seem to think should be minimum. May I recommend your little box in which you and many others seem to feel the need to demonstrate all of your inabilities. Remember, if you answer you are just using more traffic volume. You just wait... "Jack Linthicum Non Grata" will be posting shortly. :-) Pat |

It does let you greatly decrease warhead size though; the Soviets just made up for poor accuracy by putting walloping huge warheads on their missiles. Even a one kiloton warhead would knock out a ICBM silo if you could drop it straight unto the silo door. Pat |

You see, Shaddock was designed later and was just entering service when Regulus procurement was finished and it was on the way out (replaced by Polaris). Yes, things get better as time goes on. Later stuff is typically better than earlier stuff. -- "Some people get lost in thought because it's such unfamiliar territory." --G. Behn |

Mark Borgerson wrote: And the early 70's, they were probably appalled, in a different way, at the range and accuracy of the SS-N-8 sub-launched missiles. I was an uninvited observer at some of these tests, and if the center of the formation of SMRIS (Russian tracking ships) was the target, CEP was well under a kilometer. I'll have to check - that may have been the first one where the missile used a stellar navigation update during flight to make up for any inaccuracy in the sub's estimated versus real position at launch. Our Poseidon C-3 missile could put down each of its 14 MIRVs with a CEP of around 1/2 km. Pat |
