US Air Force built 500T supercomputer from 1,760 PS3 consoles for $2 million

The U.S. Air Force bought 1,760 PlayStation 3 consoles and wired them into a supercomputer called the "Condor Cluster." Peak performance hit 500 TFLOPS—33rd on the global supercomputer rankings at the time.

The economics made sense. Total cost ran around $2 million, one-tenth what equivalent traditional hardware would've cost. The Air Force stacked the consoles using over 2 miles of cabling, creating what was then "the fastest interactive computer in the entire U.S. Department of Defense."

Why PS3? Sony's Cell processor handled parallel computing tasks well. The Air Force used it for high-resolution satellite imagery analysis, radar simulation, pattern recognition, and early AI research. The PS3 supported Linux installation back then, which gave the military the access they needed.

Sony later killed "Other OS" support in a system update, closing that door. In hindsight, the project proved gaming hardware had niche value beyond entertainment—hard to imagine living room consoles doing defense work.
