Anduril Industries on Instagram: "Successful test of a prototype surface-launched Barracuda-500. We’re investing our own resources to deliver more affordable, producible, and flexible long range precision fires to the U.S. and our allies."

Golden Grip on Instagram: "Why a prototype is so important  Prototyping is all about making a functional first product as fast as possible so you can test it and make it perfect from there ️ Too often during prototyping we see crucial mistakes that we otherwise didn't think of and that we don't want to end up in the final product. And sometimes we even come to realize it was never a good product to begin with, it's a learning process. Which version do you prefer? "
