ULA today stated that they have enough Russian engines in stock to complete the 36 launch U.S. military bulk buy.

Whether they will actually complete that bulk buy remains unknown.



  • Hi Bob,
    I looked for some link to email you directly, not finding one I decided to comment on this article, since it’s remotely related to my subject. I am a regular listener to John Batchelor, and thoroughly enjoy your commentary.

    I wanted to alert you to a space related contest – put on by hackaday.com and is called the Hackaday Prize. Entrants are invited to post projects of a future looking nature, and some metric of popularity and judging is to award one lucky entrant with a Trip To Space. You would know better than me who would be providing this prize, but apparently the winner won’t be riding a Russian engine. (there’s the remotely related part).

    I entered the contest, and they also asked that we spread the word around. They had some suggestions, but since I get my Space related news form you via John Batchelor (sometimes C2C) and Hackaday encourages innovation and an open, collaborative approach to development, I thought you might like to discuss the contest.

    I’m afraid my project is not a rocket engine that seems to be in demand all of a sudden, but it’s “out there”.

    Thanks again for the great commentary !


  • Hi Eric.

    Is there a link to this contest?

    Do we know the breakdown of Atlas vs Delta boosters in that bulk buy? Assume half/half. I recall that several of the buys were for Delta4-Heavy’s which need 3 cores each. So assume 3 Heavys, that is 9 of the 36 cores. Assume the remaining 27 go half/half Delta/Atlas. They are saying they have 13 or 14 engines in stockpile? That seems pretty large to hold, just from a cost of storage perspective.

    From the Wikipedia list it looks like the Atlas-V has been launching 4-5 a year. So yeah 3.5 years would come out to that many.

    But why would they be expensive to hold?

  • I should have posted a direct link, sorry.


  • Interesting indeed. I have posted this on BtB. Thanks for the tip, and good luck!
