Pretty funny to see a former Navy SEAL saying the Navy should butt out of shipbuilding because it doesn't have the expertise it used to, but somehow has more relevant expertise on shipbuilding, contracting and complex project management than NAVSEA to tell them what they should do.
NAVSEA still has a lot of expertise, as does places like Bath Iron Works, but a lot of rules in place are because of things going extremely sideways as well as private companies cutting corners and things happening like ships burning to the waterline.
Similarly the a lot of the requirements output to the yards are based on significant in house expertise on things like combat survivability and other classified information so private industry doesn't actually have any relevant expertise to get the 'outcomes' he is talking about.
You shouldn't need to tell them how to do a weld to get to a certain standard, but you also don't want to let the industry decide for you that a lower standard is acceptable from a commercial perspective when it's all based on things like shock standards or similar that they have no idea about.
That's the big issue with using commercial marine standards; there is a really good reason we use 300 and 450 class hull valves vice the standard commercial 150 ones on warships, and it's not for geting cargo from point A to B so class societies saying we can safely replace that are talking right out of their ass.
