The decades-old rivalry between HD Hyundai and Hanwha Ocean has expanded to the US, with both giants vying for entry into the US naval shipbuilding market. Hanwha Ocean has seized an early lead by acquiring Philadelphia-based Philly Shipyard and is now pursuing Austal USA, a major supplier to the US Navy and Coast Guard. HD Hyundai is favoring partnerships with American shipbuilders over outright acquisitions.
