The USA needs drones and lots of them. And every type of applications for land, sky, and underwater. And lots of nerds with joy stick video game knowledge on how to destroy the enemy. A drone attack could take out an aircraft carrier. Especially if there was a 2 pronged attack from the air and from under water.
Some drones, but lots of smart artillery and mortar shells.
And lots of ~200 rounds per minute anti-drone guns.
