The ski jump is pretty common for everyone who doesn't have supercarriers....so, for everyone who isn't us. France, UK, Brazil, China, India, Italy, Spain, Thailand......they're almost exclusively ski jumps instead of using catapults which are very expensive to operate.

My brother is a Nuclear power technician on subs, and he described to me how the Soviet strategy for a few decades wasn't proper shielding from radiation, but having them drink red wine.
Great. A bunch of glowing sailors with radiation sickness who are also blitzed. Thumbs up, Ivan, great fucking plan.....

When I was part of the T&E team on a prototype torpedo countermeasure system, we had a meeting wherein I mentioned that Soviet subs always launched a minimum spread of four torpedoes. One of the engineers asked why and I replied, "So they can be reasonably sure one will go off."
We may lose and we may win, but we will never be here again.......
With large weapons systems like planes, integrated air defenses and ships, generation makes a difference as well.
There is a "good enough" factor where it's not just a Turkey shoot. No nation can afford to throw say WWII era surface groups at a modern navy till they run out of missiles, especially losing WWII ship size crews. But almost modern missile age British ships had a hard time with early missile age Argentine A4s armed with iron bombs. The generational gap was small enough that it got tense for Britain.
Similar phenomena in small arms I suppose. Ak47 is an old design, but good enough. But try to fight someone with rifles muskets and the modern small arms army is going to eat your lunch no matter how many people you bring.
