Jet In Vitro: I'm sorry to disappoint you, but you haven't discovered anything shocking in those notes from DOT&E. All that you are looking at is a perfectly normal set of decisions on prioritization that any program manager has to make. Any program manager has to decide what to test, in what order. The P-8 program manager chose to test ASW and torpedoes (and ASuW search sensors) first, and fatigue life and Harpoon later. The text you pasted even explains why this was, so you answered your own question in a way. All DOT&E is saying is: "Let's not place the full order until we've had chance to test those things too, but instead of holding up the production line let's place a third LRIP order so everything stays on schedule, just without signing away the full $20bn or however much it is." Nobody has any concerns about fatigue life not being what it was designed to be by Boeing. It's just one of the things that hasn't been tested yet, precisely because it is not a concern for meeting the deployment schedule and therefore not a priority.
