Antares IIB
The Antares IIB solid rocket motor used as the third stage of Scout D-1. NASA's historical Scout table distinguishes Antares IIB from the Antares IIIA used by Scout G-1; the exact motor/application is source-backed, while developer/manufacturer IDs remain unset because the historical ABL/Hercules organization boundary is not represented by a defensible canonical company record here.
