Addendum:

If I were you, I'd be more concerned about the Navy (I'm more familiar with them) fighting the last war. We did the same in WWII. Emphasis on big battlewagons in the beginning, until the Japanese taught us the future was naval airpower. Today, they're doing it again. We need smaller, more nimble ships to patrol areas like the South China Sea. Carrier battlegroups are made for larger bodies of water, and different sorts of combat. They are building more Arleigh-Burkes, but they should probably be thinking even smaller and faster.

Again, I don't think either party can be blamed for that. Our military has a history of being slow to learn. Hopefully we're watching the Ukraine conflict closely, because the Ukrainians are redefining the battlefield, using drones with surprising effectiveness. And not just for surveillance. Our Navy should also be paying attention to the use of drone boats.
