“Despite an initial rejection from Austal, South Korean firm Hanwha Ocean’s bid to buy out the Australian shipbuilder has some analysts pondering the benefits of such deal.”
This have anything to do with the US Coast Guard?
The prize of Austal USA, a supplier of U.S. Navy vessels, presumably enters Hanwha’s calculus, even if this subsidiary has relative autonomy from Austal Australia.

Still, it suggests they want an in on US military ship construction. If not Austal, perhaps some other yard.
