Over thirty years I have been involved as a contractor on several Navy development projects. Some admiral decrees that x will be done by a certain unrealistic date, no excuses. That date drives everybody to just throw stuff together and do things that will obviously cause problems when x is deployed. Being at the bottom of this sh*t pile you send memos and beg your boss to ask for extensions. But no, that boss has promised some Captain who has promised some admiral that x will be done on time. So, the project continues as if the components are debugged and working when they only work under certain circumstances or not at all.
Another problem is, for political purposes and to spread the wealth Congress or the Navy may spread what should be one integrated system among two or more competing companies and order them to work together. That work-together part seldom gives you the nicely integrated slickly functioning system the Navy needs. Every bump at the component interfaces means time lost as the companies fight over who owns the problem.
Major weapon procurement is so bunged up it is astonishing we can field anything that works as intended.
If the hardware works right the first time out, this is a failure, because there's no money flow needed for do-overs.
