See what happens when you doubt the board's narrative?  LOL!    The reality is that we simply don't know.  Experience tells me that the 'official' story is likely incomplete, but lacking info beyond press releases and public statement, determining the 'real purpose' of the ship is conjecture.  Indeed, your faith in the official story is as much conjecture as any scenario that feeds plausible belief that the ship is supporting secret rescue or enforcement operations.
