>> making better versions of old weapons is a waste of time.
Except for hypersonics being a basic step up for ballistic missile tech, a better warhead/payload atop a rather standard missile. Those submarines are incremental improvements on very old sub designs. Drones have been around for decades too. Even autonomous "suicide drones", but we used to call those cruise missiles with loiter capacity. Despite the constant rhetoric there is actually very little revolutionary in the modern battlespace.
