US defense contractors drop Anthropic AI after federal ban
Synopsis
US defense contractors, including Lockheed Martin, are expected to remove or review Anthropic AI tools following restrictions introduced under former President Donald Trump. The policy affects the use of certain external artificial intelligence systems in sensitive defense projects. Reports also indicate OpenAI is exploring potential defense partnerships, including discussions linked to NATO, as AI companies compete for government technology contracts.
U.S. agencies and defense contractors are phasing out Anthropic AI tools following a federal directive over safety and usage disputes. Government entities are shifting to alternative providers such as OpenAI. The move affects military and civilian systems and reflects broader tensions over AI deployment in national security and ethical safeguards.
Key Highlights
- Federal agencies instructed to end use of Anthropic AI products under U.S. directive
- State Department switches its chatbot from Claude to OpenAI’s GPT-4.1 model
- Defense contractors like Lockheed Martin expected to remove banned AI systems
- OpenAI explores broader defense and NATO-related AI agreements
Several major US defence contractors, including Lockheed Martin, are preparing to discontinue the use of artificial intelligence systems developed by Anthropic following a federal restriction introduced under former President Donald Trump. The move affects AI tools used in certain government and defence-related programs.
The restriction applies to the use of Anthropic’s AI models in projects involving sensitive US government work. Contractors are reviewing their systems to ensure compliance with federal policy, particularly in programs linked to the Pentagon.
Pentagon-Linked Projects Under Review
Anthropic’s generative AI tools, including its Claude model, had been integrated into selected federal workflows and defence research initiatives. Reports indicate that agencies were given timelines to phase out the company’s software where required.
The decision follows disagreements between Anthropic and U.S. defence officials over contractual terms and permitted uses of its AI systems. The policy shift has prompted companies working on classified and national security contracts to assess existing deployments.
Defence firms depend heavily on federal contracts, and compliance with government directives is essential to maintain eligibility. Lockheed Martin, which reported $67.6 billion in revenue in 2024, is among contractors reviewing its AI integrations.
The US defence budget has exceeded $800 billion annually in recent years, making it one of the largest technology procurement markets globally. Artificial intelligence tools are increasingly used in logistics planning, data analysis and operational support across the defence sector.
OpenAI Explores Defence Opportunities
At the same time, OpenAI is reported to be exploring defence-related agreements, including potential discussions involving NATO. The developments come as AI companies compete for government contracts in the United States and allied countries.
Anthropic has not publicly detailed the financial impact of the restriction. The policy marks a shift in how AI vendors engage with US national security agencies, particularly in areas involving sensitive data and operational systems.
