<i>>> "It shows that their rocket is better than 70% complete"<br /> /> Is that 70% by weight, by volume, by cost, by number of subsystems? I they had more hard information available.</i><br /><br />It's 70% by good marketing. The K1 has been 75% complete for almost a decade - it's another hangar queen built the old, expensive way. Kistler burned through nearly $1Billion trying to build it, then proceeded to go belly-up. I'm not very confident in RpK or ATK finishing it. <br /><br />IIRC, the vehicle's 1st and 2nd stage tankage, intertanks, thrust structures were completed. They contracted much of the structures out to LockMart. The avionics may be done, but would be completely outdated now, as would any original software. Kistler had a warehouse full of Russian NK 33 and 43 engines, but I don't know what the status of that is - they had enough engines to build several K1s. Hanging issues probably include approach/docking hardware, the cargo capsules, TPS, new health-monitoring and thousands of hours of integration.<br /><br />The "70%" number is handwaving, because everyone knows the last 10% takes 90% of your time. I'd be more confident if Rocketplane had flown something beefier than a Lear jet. <br /><br />The only up-side to this is that if they succeed in flying the K1, perhaps ATK will give up on developing the ludicrous Stick and put the CEV on a K1 instead. <br /><br />Josh <div class="Discussion_UserSignature"> <div align="center"><em>We need a first generation of pioneers.</em><br /></div> </div>
