Orbital Sciences Corporation
Historic US launch operator (1982-2018); pioneer of air-launched small satellites (Pegasus) and the Antares medium-lift vehicle. Merged with ATK in 2014 to form Orbital ATK, then acquired by Northrop Grumman in 2018 to become Northrop Grumman Innovation Systems. This entry preserves the historical operator identity for pre-2018 flights.

METHODOLOGY
Launch history and subsystem outcomes aggregate from AstraVeris's launch_events table with Wilson 95% lower bounds on success rates. ARI scores come from the 11-factor composite (/finance/methodology/). Constellation counts derive from the live CelesTrak/GCAT object catalog. Gov contracts from USAspending.gov awards; private deals from deduplicated pipeline deal extraction. Absence of a row means "not tracked" — we never fabricate. See /methodology/ for the full data model and /data-licensing/ for licensing terms.
