Description
Historical Thiokol solid rocket motor variant used as the third-stage motor on Delta II 7925-series vehicles, including Delta II 7925H; it remains distinct from STAR 48BV.
NASA identifies the Delta 7925H stack as XLET + nine GEM-46 motors + AJ10-118K second stage + Star 48B third stage and lists Thiokol as the Star 48B manufacturer.
NASA’s Delta II characteristics table identifies the Thiokol Star 48B third-stage motor and separates it from the first-stage GEM motors and second-stage AJ10-118K engine.
