As described in TFA, one of the cheapest weapons now made in USA, the "Low-Cost Uncrewed Combat Attack System" is presumed to cost around $55K.

The funny thing is that this was designed in USA based on what was learned by reverse-engineering one of the models of Iranian Shahed drones.

That was certainly the smart thing to do, but it contrasts with the very frequent opinions expressed on many US forums, which disparage some other countries, mainly China, because supposedly they copy other technologies, instead of being "independent innovators like USA".

Fortunately for USA, they still have engineers who understand that the most efficient strategy is to first copy whatever others do better than you, and then improve on it. There are no such things as "independent innovations", any successful innovation is applied over a countless number of previous innovations discovered by others.
