The competition heats up: Officials at Aerojet Rocketdyne yesterday lobbied hard for Congress and ULA to finance and buy their new AR-1 engine, designed to replace the Russian engines used in the Atlas 5 rocket.
More here, including the threat by those officials that the development of the engine could slip past 2019 if Congress doesn’t give the company more money.
The first comment at the bottom of the page of the first article above I think possibly outlines some of the reasons behind Aerojet Rocketdyne’s bid to buy ULA.
The development of the Blue Origin BE-4 is underway, and a launch vehicle like the proposed Vulcan would certainly be an asset to national security and commercial space development. But, as was stated, such a LNG/LO2 vehicle would need a different infrastructure to support it. ULA’s Atlas V is the most mature and reliable [launch vehicle] we have. The problem with it is a political one, because of its using the Russian RD-180 engine. From what has been published, plugging the BE-4 into an Atlas V is a non-starter; the BE-4 is meant for the Vulcan…if ULA can obtain funding on something more than a per-quarter schedule! Aerojet-Rocketdyne’s AR-1 would be a more logical choice to replace the RD-180, BUT…ULA won’t release the Interface Control Documents (ICD’s) to Aerojet-Rocketdyne. Hence, AR’s attempt to buy ULA.
