SpaceX has had 6 sequential successes, by ULA's definition (which is a good one).
Recent inroads by SpaceX into its market had led one Lockheed official to comment abou the new upstart's capability:http://www.washingtonpost.com/business/economy/spacexs-entry-into-70-billion-us-launch-market-draws-lockheed-jab/2012/12/23/a0e4fd0c-4a2e-11e2-b6f0-e851e741d196_story.htmlSo what's the future of competition betweeen SpaceX and established players like Lockheed and Boeing?
I understand testing the F9 v1.1 three times (compared to v1) as it is a whole new beast, but I wonder how the ULA rockets were certified considering how many different core and booster combinations are available. Did every configuration need three successful launches to be certified?
Of course there will be people arguing that the failure to put the Orbcomm satellite into its correct orbit means the last flight was a failure. P
Not sure about F9 v1.1 but I recall some of those Delta and Atlas configurations have never flown. For example IIRC part of the CCiCAP is to launch an Atlas with the a version of the Centaur that has not flown before to verify that configuration (I think Boeing got the money so presumably they will fly with a CTS-100 simulator).

So there are 2 Atlas V and 3 Delta IV combinations that would need to be certified.
Going from 95% reliability to LEO to 99% reliability to GTO could be an expensive proposition for SpaceX.

Personally I think it should be called a partial success, as there should be a big caveat on the "failure". Yes Spacex didn't put it into its proper orbit, but it was not put into the proper orbit because NASA calculated it had only a 95% chance of proper orbital insertion, not 99% as required by ISS safety rules. The rocket had a 19 in 20 chance after losing an engine of completing both the primary and secondary missions. I'm fairly sure it could have gotten the job done if not for ISS regulations. While the Falcon 9 has had teething problems, they pale in comparison to how the Ariane 5 started out: Right now the Ariane 5 might just be the most reliable launcher of the current era if we're going by consecutive successive launches. ULA might be able to match the Ariane 5 in reliability, but they've been run out of the commercial market on prices by Ariane & the Russians, whose failure rates for rockets like the Proton are even higher. ULA is going to have to make some major adjustments to their business model if Spacex starts running off increasing numbers of consecutive launch successes. This is especially true because there's a possibility that even Orbital might someday get into their market with an upgraded Antares. My suggestion to the Lockheed manager is less blustery talk and more action to be more price-competitive.
Two engined Atlas V Centaur wasn't even designed.

It was NASA who determined that they were not allowed to proceed.
