The senior retired naval person will certainly have an enhanced safety culture: submarines operations are far less forgiving than modern aircraft, with equal, or worse, catastrophic outcomes when things go wrong. However, I fear that the admiral will be used to working in a far less financially constrained atmosphere than Boeing operates. Bradly speaking, what the submarine service wants, the submarine service gets, in safety terms, which, from the reports in this thread I doubt will have been the norm in Boeing up til now.
