Offshore Wind Development Faces National Security Concerns Under Trump Administration

The Trump administration halted offshore wind development, citing national security concerns. Since late last year, significant projects were stopped, and leases were bought back based on a classified report from Defense Secretary Pete Hegseth. Interior Secretary Doug Burgum emphasized the national security threat of offshore wind turbines.

The backdrop of this decision includes President Trump’s aversion to wind turbines and his focus on boosting fossil fuels to achieve energy dominance globally. According to national lab estimates, U.S. coastal turbines could generate enough electricity to meet the country’s annual needs.

Security Risks of Offshore Wind

Wind turbines pose risks by interfering with radar, creating false targets on screens. Burgum expressed concerns about undetected autonomous drones navigating through wind farms due to this interference. The Department of Energy stated radar systems can adjust their detection thresholds but might miss actual targets as a result.

National security expert Kirk Lippold mentioned that radar operators differentiate real threats like boats or drones from clutter. He noted that undetected drones reaching wind farms indicate larger security issues.

Legal and International Perspectives

The DOJ shared classified information in November 2025 with the Bureau of Ocean Energy Management (BOEM) about new security risks from offshore wind. BOEM subsequently paused five significant East Coast projects. Legal challenges ensued, with states suing to resume construction. Federal judges allowed all projects to continue, with Judge Royce Lamberth questioning the administration’s motives.

Sweden also expressed security concerns, approving two offshore farms but rejecting 11 others. Green Power Sweden’s CEO questioned the rationale given existing technological solutions for radar interference. In contrast, the UK implemented new radars to coexist with wind farms.

Despite setbacks, advocacy exists for offshore wind as a defense asset, with surveillance and monitoring potential highlighted by climate think tank E3G.

Concerns and Criticism

The Interior Department justified lease buybacks by citing immediate security risks and potential negative impacts on energy systems and the environment. This action faced criticism from several states and retired military officials such as Vice Admiral Dennis McGinn, who argued offshore wind is compatible with national security if managed correctly.

Economist Diana Furchtgott-Roth supported the administration’s caution, emphasizing defense concerns and the benefits of reliable gas, coal, and nuclear energy over dependency on foreign-made turbines.

Congressional Briefing

Senator Jack Reed received a classified briefing, finding the reasoning unconvincing. Reed aims to introduce a measure in the defense bill for a thorough evaluation of wind projects, requiring military explanations within 180 days.

This initiative faces challenges as Reed acknowledges the administration’s ongoing opposition to wind energy.
