Trump cites national security to stop offshore wind development. Here’s what to know

The administration of President Donald Trump has worked since late last year to halt offshore wind development, claiming the projects pose a national security risk. This effort has included the cessation of work on major projects and the buying back of leases, including those off the coast of California.

Interior Secretary Doug Burgum stated that a classified report from Defense Secretary Pete Hegseth proves offshore wind is a national security threat. Specifically, Burgum expressed concern that radar interference caused by wind towers could allow autonomous drones to go undetected. He also claimed that the vibration from these towers could impact undersea sonar.

The Department of Justice noted that defense officials provided the Bureau of Ocean Energy Management (BOEM) with classified information in November 2025 detailing new national security risks. Following this, BOEM halted construction on five large East Coast projects shortly before Christmas. Burgum argued these actions were necessary to address vulnerabilities near East Coast cities and the evolution of adversary technologies.

Legal Challenges and Court Rulings

The construction freeze prompted lawsuits from impacted developers and various states. While the Department of Justice argued that federal courts should not second-guess military assessments of risk, judges reviewed the classified material and allowed all five wind farms to resume construction.

In January, Senior Judge Royce Lamberth of the U.S. District Court for the District of Columbia put the Revolution Wind project, serving Rhode Island and Connecticut, back on track. Lamberth suggested the national security reasoning may have been pretextual to hide true motives, noting that the government did not apply the new concerns specifically to Revolution Wind and that BOEM waited until December to act on information received in November.

Meghan Greenfield, a partner at Jenner & Block LLP, noted that the administration's frequent use of national security arguments across different contexts has led to increased skepticism by the courts.

Expert Debate on Security and Energy

The administration's position is contested by some military and security experts. Retired U.S. Navy Vice Adm. Dennis McGinn, who previously commanded the fleet for naval operations across the eastern and northern Pacific Ocean, stated there is no showstopping national security issue that invalidates years of lease area analysis. McGinn argued that radar interference was recognized early and adequately addressed, pointing to thousands of operating turbines in Asia and Europe.

Kirk Lippold, a former commander of the USS Cole, added that radar operators are trained to distinguish live tracks—such as missiles or drones—from clutter. Lippold stated that if drones are not detected before reaching a wind farm, we have bigger national security issues.

Conversely, economist Diana Furchtgott-Roth of the Energy Policy Research Foundation believes the administration is acting prudently. She argued that the military's views should be taken seriously, that the U.S. Should not depend on Chinese-made turbines, and that coal, gas, and nuclear power provide more reliable and affordable energy.

International Context and Legislative Response

Other nations are grappling with similar tensions. Sweden recently approved two offshore wind farms while rejecting 11 others due to security concerns. However, the UK government announced in March that it purchased new air defense radars to mitigate anomalies created by wind farms, promoting the coexistence of air defense and energy production.

In the U.S. Senate, Ranking Member of the Senate Armed Services Committee Jack Reed of Rhode Island said he found the administration's reasoning uncompelling after a classified briefing. Reed is attempting to include a measure in the defense bill to mandate a 180-day deadline for the military's siting clearinghouse to evaluate wind projects and provide a thorough analysis justifying any decisions.

The administration's push against wind energy coincides with a broader desire for energy dominance through the promotion of fossil fuels. While national lab estimates suggest coastal turbines could provide enough power for the nation's annual electricity consumption, the administration has used emergency orders to keep fossil fuel plants online and is currently holding up onshore wind development.

Current developments include ongoing lawsuits from several states regarding the Interior Department's lease buy-backs and the pending legislative effort by Senator Reed to force transparency in military siting evaluations.
