This builder page represents a partnership-style catalog facet rather than a single continuing company. The cataloged AC-208 Combat Caravan starts with the Cessna Caravan, a rugged single-engine utility turboprop now marketed through Textron Aviation's Cessna brand.
ATK and later Orbital ATK supplied the armed special-mission conversion lineage that turned the Caravan into an ISR and light-attack aircraft. Northrop Grumman acquired Orbital ATK in 2018, and its current special-mission aircraft materials describe the AC-208 Armed Caravan and AC-208 Eliminator lineage.

This is a combined manufacturer facet from a weapon record, not a single corporate entity. The profile keeps Cessna/Textron Aviation airframe context separate from ATK/Orbital ATK/Northrop Grumman mission-conversion lineage.
