having worked, and still working within the navy system, on the seahawks, and having just completed phase 1 of seaking mods, i dont doubt the ability of the navy engineers, they are just as skilled as any, what is the killer in the navy is the navy system itself, its impossible to do a job to the best of your ability, and the navy paperwork and support is so incredibly frustrating and works against you, that to actually get the job done, corners have to be cut. the navy demand such a job in a set timeframe, yet cannot supply accurate drawings, (as they didnt purchase the rights to the engineering drawings when they bought the type) they refuse to spend any money on required tooling, or for correct part stocks for that matter. its the equivalent of the navy asking you to run a marathon in world record time, then proceeding to chop off both your legs, and wondering why you didnt meet their expectations.
