I whakawhiwhia a Pratt & Whitney ki tetahi kirimana mai i te AFRL ki te whakawhanake i tetahi miihini scramjet-hydrocarbon i ahu mai i te whanaketanga o te miihini SJX61. Ko te miihini SJX61 i hangaia mo te NASA X-43C, i whakakorehia i te mutunga. I whakamahia te miihini ki te kaupapa Whakaaturanga Miihini Scramjet a AFRL i te mutunga o te tau 2003. I tohua te waka whakamātautau rererangi scramjet X-51 i te 27 o Mahuru 2005.  Pātai: He aha te mutunga o te hōtaka rererangi X-43C a NASA?
