I watched a video the other night that talked about the state of various navies at the beginning of WW2.
Consider the size of the German Navy in 1939: 103 ships, 7 capital ships, 8 cruisers, 22 destroyers, 24 torpedo boats and 72 subs.
Their famous "plan Z" was to have nearly 800 ships, with almost 250 U-boats in service by 1948.
Wars are fought with what you show up with.
Germany started with 72 subs (57 operational). They had no-where near what they'd hoped to when they kicked off Part 2.
That said, Canada had only 6 warships and 3500 people in our Navy in 1939.
Who had the industrial capacity and space to build more ships faster?
Well, Germany....but also our allies.
Canada was able to take various shipyards across the country that were designed to build coastal steamers or fishing boats, and build ourselves a Corvette navy. It's more complex than that, but the real way to build new capacity for wartime production is to repurpose non-military capacity and make it military.
You're right - we have very complex warships, and making those is really tough, specialized work that only a handful of shipyards in Canada can do.
So.
What do we do? We become, once again, a Corvette Navy. Simplified ships, with simplified armament, that are faster and cheaper to produce in series production by smaller yards/facilities that can be repurposed into wartime capacity.
How close are we to 1939? I suspect we're at about 1937....maybe '38.
Emelia Earhart is making her 'secret spy flight' over enemy territory, companies are looking seriously at defense production capabilities, governments are talking mobilization, and the world is edging closer to open conflict again.
The new 5-year plan to starve Ukraine 5 year (Holodomor-redux?) is already in progress, and has been since 2014 with the invasion of Crimea.
So. I suspect that part of the "Continental Defense Corvette" plan is to find a design that will be capable enough in combat, but simple/small enough to be able to be produced in great numbers by dispersed (read civilian) shipyards.
But.
What do I know....history doesn't repeat itself, does it?
