Let us assume a HLV with a reliability of 95% - a >bit higher than the current Titan fleet with about 80 launches, and Nits and trivia: Actually, the Titan fleet's reliability is a bit more that 95%. The advertised rate is 96.something%. Also, depending on which Titan III versions you count, the total number of launches could be said to be over 100. (I'd guess that you're counting only the versions with SRMs attached). I'd also like to point out that the Titan IV is 2 for 2, making for a 100% success rate :-). Question: Do Shuttle payloads require insurance? Points: Note that the payload costs given for classified satellites imply that the Air Force is probably not really that interested in cheap boosters. Also, note that there's no reason to think that reusable boosters are any more reliable than expendables, notwithstanding Mr. Larrison's preference for reusables. --Glenn Serre serre@tramp.colorado.edu
