The U.S. military's use of artificial intelligence is surging. According to The Defence Blog, Pentagon AI use jumped 1,775% in just one year — a striking measure of how quickly the Department of Defense is folding AI tools into its operations.
That rapid buildout is now drawing scrutiny from Capitol Hill. According to the Sierra Sun Times, Senator Elizabeth Warren is pressing the Department of Defense for answers on its military AI contracts and demanding that those contracts be released. Her push signals growing pressure for transparency around how public money is being spent on defense AI and which companies are winning the work.
The momentum isn't limited to the United States. The Korea Times reports that a "D4D" hackathon is laying the foundation for a defense AI ecosystem across the Asia-Pacific region, pointing to a broader international race to develop and apply these tools for military use.
The commercial stakes are being tracked closely as well. A market analysis published on openPR examines the United States Military AI Market over the 2026–2035 period, reflecting expectations that defense-related AI spending will remain a significant and growing sector in the years ahead.
Together, these developments sketch a fast-moving picture: adoption is climbing sharply, allied nations are building out their own capabilities, and investors are betting on a long runway of growth. At the same time, lawmakers are beginning to ask harder questions about oversight and disclosure.
Why it matters: as the Pentagon leans harder on AI, the gap between how fast the technology is being deployed and how much the public can see about those decisions is becoming a central fight over accountability.
