6th grade: industrial drawing, hand tools, shop safety, home maintenance: replacing windows, wiring bulbs, switches and outlets, faucet installations. Basic fabrication with plastic, hammered metal forming and band sawing wood.
7th & 8th grade: Metal: forge, lathe, welding (electric arc & acetylene), sheet metal (cutting, bending, punching, riveting, soldering) Wood: turning on lathe, table sawing, planing, routing, laminating, veneering, clamping, etc
In high school, all of the above plus architectural drawing, project management, metal machining, and fiberglass (mold design, making and part-making). Student projects included dune buggy car bodies, boats, water skis, furniture and all the usual (cutting boards, knife blocks, spice racks, etc.)
In today's world, parents (and lawyers) might find it unsafe for boys (very few girls elected to take these classes) but in seven years of shop, I only recall one serious accident involving the loss of a finger tip.
I went on to college major in Industrial Design and business then spent a career designing and producing projects for major consumer product company clients.
I also remember that we were trusted to behave like adults in front of heavy machinery like routers, circular saws and lathes. No incidents whatsoever aside from minor cuts, which is normal. We were genuinely interested and behaved accordingly, nobody wanted to get hurt and / or get kicked out of the class
P.S. Not sure of how it works in the US, but we also had "shop classes for girls". The curriculum for those consisted of the basics of cooking, baking and working with fabrics (starting from sewing two pieces together in grade 5 and gradually evolving to designing and sewing clothing for yourself by grade 9). Though, in my opinion, those things shall be taught to everyone, not just girls
Probably? It would be a disaster every time one crashes, would carry a huge proliferation and terrorism risk. Oof.
In the 50's some countries were that crazy and they even put reactors in space. Two of which crashed and one contaminated a huge area in Canada. Luckily common sense prevailed and these things don't happen anymore. Though nuclear ships still exist, there's only a few icebreakers in the civilian fleet AFAIK.
