Trump Administration Halts Five Offshore Wind Projects Citing National Security Concerns

Administration Cites National Security

The Trump administration announced on Monday, December 22, 2025, an immediate pause on leases for five large-scale offshore wind farms along the East Coast of the United States. The Department of the Interior stated that the decision was based on 'national security risks' identified in 'recently completed classified reports' from the Department of War, formerly known as the Department of Defense.

Secretary of the Interior Doug Burgum emphasized the government's primary duty, stating, 'The prime duty of the United States government is to protect the American people.' He added that 'Today's action addresses emerging national security risks, including the rapid evolution of the relevant adversary technologies, and the vulnerabilities created by large-scale offshore wind projects with proximity near our east coast population centers.'

Radar Interference Concerns

The primary national security concern cited revolves around potential radar interference. According to the Department of the Interior, the movement of massive turbine blades and their highly reflective towers could create 'clutter' on military radar systems. This interference, they argue, could make it difficult for the military to identify and locate legitimate targets, thereby hampering defense operations.

The pause is set for an initial 90-day period, with the possibility of extension, to allow the Department of the Interior, the Department of War, and other relevant agencies to work with leaseholders and state partners to assess and potentially mitigate these identified risks.

Affected Projects and Industry Reaction

The halt impacts five significant offshore wind projects that were already under construction or in advanced stages of development:

• Vineyard Wind 1 (off Massachusetts)
• Revolution Wind (off Rhode Island and Connecticut)
• Coastal Virginia Offshore Wind (CVOW) (off Virginia)
• Sunrise Wind (off New York)
• Empire Wind (off New York)

These projects had previously undergone review and received approval under the Biden administration, which had concluded there were no undue national security concerns. The decision has drawn sharp criticism from wind developers and clean energy advocates, who warn of potential losses amounting to billions of dollars in investment and thousands of jobs. Shares of companies involved in these projects, including Orsted, Dominion, and Equinor, experienced declines following the announcement.

Broader Context and Criticism

This move marks an escalation in the Trump administration's long-standing opposition to wind energy. Critics, including some national security experts, have questioned the justification, describing the radar interference claims as 'spurious and nonsensical.' They argue that such issues are known and have existing mitigation solutions, such as software patches or radar upgrades. The announcement also follows a recent federal court ruling that struck down a previous Trump executive order blocking wind project permits as 'arbitrary and capricious' and contrary to law.
