Fast, reliable, cheap vs CATS
Of course this is why the Russians have done so well with space. They could generally get away with less reliable systems and just try a few extra times to get it to work. Greg Actually, Greg, the Russians have the most reliable launcher in the world, the R7 family, also known as Soyuz. Here's a quote from Mark Wade's Encyclopedia Astronautica: "By the year 2000 over 1,628 had been launched with an unmatched success rate of 97.5% for production models. Improved models providing commercial launch services for international customers are even now entering service. It appears the R-7 will easily be in service past the 50th anniversary of its first launch." Compare this to Titan IV, Space Scuttle or Ariane... |

Well, if you compare it to the shuttle, the shuttle is MORE reliable. It's probably more accurate to say that the R-7 is the only launcher in the world with a good stastitical model. One more failure won't budge it much from the 97.5% success rate. Another shuttle failure would move the shuttle down from 98% success to just under 98% success: a notable drop. |
