Beyond the RD-180March 21, 2017This report explores how the United States came to depend on the Russian RD-180 rocket engine as part of the Evolved Expendable Launch Vehicle (EELV) program, realistic options for the engine’s replacement in the coming decade, and potential space launch acquisition strategies for the future. The first section provides an overview of the history of the development and evolution of EELV, including the early origins of both the RD-180 and the EELV program, as well as the EELV acquisition strategy, the creation of the United Launch Alliance, and the entry of other private competitors to the launch market. The second section discusses the more recent controversy over the RD-180 in the U.S. Congress after Russia’s annexation of Crimea in 2014, including recent efforts to cap the number of Russian engines that U.S. companies can acquire. The third section describes five options to transition from the RD-180 that could be implemented within several years. These options include the oft-cited “drop-in replacement” option, using new engines on new launch systems and using currently available alternative launch vehicles. The last section discusses planning for the future of space launch acquisition. This discussion includes: challenges to the current strategy, the major considerations in developing a renewed acquisition strategy, and a few specific examples of what a new national security space launch acquisition strategy could look like. While the details for how and when the RD-180 will be replaced are not yet settled, the consensus within the U.S. Congress and executive branch remains that the United States must end its reliance on the RD-180. This report explains the impetus for finding an alternative engine, explores the options that are available going forward, and describes the challenges that will be placed on the federal government and the private sector in doing so.
No mention of OA NGLV in report.
The first assumption is that the requirement to end the U.S. military’s use of the RD-180 engine by 2022 or sooner, as specified in the FY17 NDAA, will remain in effect.
The second assumption is that the United States will continue its policy of maintaining two independent vehicles for national security space launch.
The third assumption is that SpaceX’s family of Falcon launch vehicles (including the Falcon 9 and Falcon Heavy) will be one of the launch vehicles used by the U.S. military.
This analysis is therefore focused on which options are available for a second independent launch vehicle in addition to the Falcon family of vehicles.
That is because OA NGLV is only in internal study and its fate as to whether to proceed or not is slated to be decided around the June 2017 timeframe per OA IR transcripts. If OA proceeds with its NGLV then you can expect it to be added into the next report.
If I'm not mistaken, this is not true. Orbital ATK is studying it for a DoD contract. The ablative nozzle extension for BE-3U is also part of that program. And SpaceX go a contract for a higher performance upperstage, if I'm not mistaken.Could the two launchers on this BO tweet be on the same scale? AKA a single BE-4 engine New Glenn with a BE-3U; RL-10C /CECE, XCOR... upper-stage.
