Flak cannons are also really cheap to produce and use. But downing a modern fast jet with one is still hard to do. Especially when they can fire over the horizon.
The war in Ukraine looks like it does because Ukraine has had to fight with constant equipment shortages. It's not really the future of warfare that modern militaries are prepping for.
Yeah I think people are underestimating drones here.
There is a reason this administration is fast tracking drone production and easing up on procurement. Some stuff doesn't need super sophisticated systems with traditional processes to get off the ground quickly with a cheap swarm approach.
It's probably the only thing I can agree with this administration on.
With that said America would be doing both drone swarms and advanced missile systems where they are most effective.
