    AJR: Dead company walking

    AJR is alive and well just minus the large liquid rocket motor division, The company make most of their income on tools of war.

    They lost monolithic solids to OA too. If they drop RL-10 for ACES there is nothing left but scraps of NASA handouts on the space propulsion side.

    They are still in the monolithic solid contest for the upcoming USAF ICBM.

    The RL-10 days are numbered. It should be replaced by the Blue BE-3U eventually. Especially since both the Centaur V and the EUS needed 4 RL-10 or 1 BE-3U each. Fun factoid, 4 RL-10 ($17M x 4 = $68M) costs more than booking a Falcon 9 flight ($61M)!

    $50M flight proven

    I don’t think the current price of an RL-10 is anywhere near as low as $17 million. More like high 30’s or low 40’s.

    The last price that was discuss on the NSF forums was $17M by the forum members.

    We have no idea what a new RL-10 costs since AJR have not build any new ones recently.

    The RL-10 in use right now are conversion of the remaining RL-10B block buy that Boeing purchased at the start of the Delta IV program.

    Regardless, even at $17M per RL-10. Engines for the Vulcan Centaur V and the SLS EUS are still more expensive than a brand new Falcon 9.
