No, no, no. BARR is not the stealth bomber!! if the stealth metaphor / hint applies in this case, it is Rosen & Donoghue. They have now, right now, been uncloaked and brought to the fore.  I think that's the stealth bomber. Barr is the artillery performed in preparation of the major initiative. Decks now cleared, law and order, step aside.  Anyway, that's how I would interpret 'stealth bomber'.
