I am afraid it is not just one fleet. Across the entire Pentagon, there is a pernicious culture of lack of responsibility, shoddy work, cynical corporatism, and seemingly more of a focus on securing a lucrative post-service job than on actually, you know, serving. The whole “duty, honor, country” thing seems to have gone out the window. Sort of like the old joke perverting the Boy Scout oath" On my honor/I’ll do my best/to help myself/and cheat the rest."
And this starts at the top. Civilian and military leaders in the past decade or two have IMO shown a remarkable lack of integrity, honesty, and moral courage. This does a disservice to the men and women serving under them, and to the country as a whole. There are simply way too many accounts of things ranging from simple if egregious misbehavior to outright corruption, incompetence, and dereliction of duty to ignore.
