## Resource

What does it take to build a defense manufacturing empire when the supply chain, testing, and national security all collide? In this condensed summary of Relentless, host Ti Morse speaks with Mach Industries founder and CEO Ethan Thornton about scaling solid rocket motors, jet engines, and weapons systems from scratch. This minutes-long version of the full conversation breaks down how Mach is retrofitting bunkers, building a larger energetics facility, navigating scarce precursor materials, and using vertical integration to move faster. You’ll learn why asymmetry matters in modern warfare, how Thornton balances OPEX, CAPEX, and speed, and what it takes to know when to kill a program and start over. Listen now to get the key ideas in minutes.
