They would have to build a new shipyard to build a diesel boat
All of ours are full of new construction or up grades and repairs or other naval vessels.
Something like years behind schedule
but I would like to see it happen for coastal defence after a major war
Keeping the enemy at bay for sure in the Gulf of Mexico and the Gulf of Alaska for just two reasons,
but as we all know any major shipyard would want export the diesel-electric AIP boats and that
would take years, plus permission.
Just hopeful wishing
