Yes Wood from America and Russia. But not built in America. Why ? Precisely because the colonial system ad Britain saw It in the 18th century was : Monopoly of manufacturing for Britain and the colonies provide Raw materials and are not even allowed to trade with third countries without transit through Britain.
That was one of the reasons why the 13 colonies decided to severe links with Britain. They wanted a more open decentralized system.
You are dreamng about some kind of always unvincible Britain whatever catastrophee falls on Britain's head. This is not serious.
Before the second half of the 19th century, there is no sustainable Royal Navy without the kernel of assets that had its heart in Britain (its industry, its infrastructure, its qualified workers, and most of all its financial system.
There would be no possible return for those who leave thousands of miles overseas.
Either Britain holds (and It had incredibly high probability of holding) or it falls.
But if it falls, it damn falls. In the 18tt century or around 1800, Britain's fall means :
- kissing goodbye to Sotland and Ireland,
- bankrupcy of the City. The financial place of London loses its role of world number one financial center,
- some kind of end of the Navigation act that was key to building Britain's trade Navy domination,
- fall of the british ruling class composed of the high nobility and of the financial and business gentry and some kind of social unrest and economic meltdown comparable to what France faced between 1789 and 1799,
- loss of many colonies instantly or in a few years and especially no ability to keep on holding India because Indians will revolt,
- limitation on the number of ships its Navy can hold.
This is chaos for a generation.
It may be hard to conceive but England was a complex system that could crash if its foundations crumbled.
