That will be some serious repair bill.
Regarding our lack of manufacturing skills and capacity, I couldn't agree more. More than centuries ago the economist Adam Smith saw where we were heading when he wrote The Wealth of Nations and observed:
To found a great empire for the sole purpose of raising up a people of customers, may at first sight, appear a project fit only for a nation of shopkeepers. It is, however, a project altogether unfit for a nation of shopkeepers, but extremely fit for a nation whose government is influenced by shopkeepers.
Government has been malignly influenced by shopkeepers of one sort or another for a very long time: giving buying and selling priority over manufacturing.
