Defense startups raid auto and fracking sectors for parts to speed weapons output

Defense tech startups are repurposing automotive components and oil and gas industry parts to accelerate weapons production for the Pentagon. Companies like Castelion are using auto industry chips and fracking pipes to build rocket motors, aiming to meet high demand while reducing costs and lead times. Traditional defense contractors such as Lockheed and Northrop Grumman warn of rocket motor shortages, prompting new entrants to adopt methods from drugmakers and leverage alternative supply chains.
