Silicon Valley Companies Move Into U.S. Defense Work

Silicon Valley’s role in military contracting now extends beyond supplying individual tools. Sharon Weinberger described an industry ecosystem of founders, investors and executives whose companies are winning major agreements directly from the Pentagon. Traditional contractors remain, including Northrop Grumman, Lockheed and Boeing, but technology firms are increasingly joining their ranks as large defense suppliers.

SpaceX and Palantir helped open that market around 2003-2004. Elon Musk established SpaceX in 2003, while Peter Thiel and Alex Karp started Palantir around the same period. Unlike conventional weapons programs commissioned and funded by the government, many Silicon Valley products are developed with venture funding or other private capital. The companies therefore retain ownership of the core technology, potentially giving their leaders influence over its military use.

That tension surfaced early in the Ukraine war. A satellite Internet network supported the Ukrainian military, but Musk rejected a request to use it during an operation in Crimea. Meanwhile, some troops had welcomed Silicon Valley software. Soldiers deploying to Afghanistan found Palantir’s point-and-click products more familiar and capable than equipment they had received from established contractors. The industry’s influence has continued growing as technology executives developed closer ties with Donald Trump during his second administration and pushed against restrictions on artificial intelligence. For Simi Valley residents following federal defense priorities, the central shift is both technological and structural: private firms can help determine not only what battlefield systems are built, but how company-owned technology may be deployed.
