The Trump administration has taken steps to stop offshore wind development, announcing in late 2025 that Defense Department officials identified new national security concerns with such projects. Interior Secretary Doug Burgum stated that classified information from the Pentagon proves offshore wind poses risks, citing potential interference with radar systems and submarine sonar capabilities. The administration halted construction on five major East Coast projects in December and has moved to buy back offshore wind leases, including those off California.
Defense officials provided classified information to the Bureau of Ocean Energy Management in November 2025 detailing the alleged security risks. Administration officials argued that the rapid evolution of adversary technologies and vulnerabilities created by these projects near population centers necessitated immediate action. However, federal judges who reviewed the classified material allowed all five halted wind farms to resume construction. Senior Judge Royce Lamberth expressed concern that the stated national security reasoning may have been “pretextual,” noting that the government did not apply its concerns specifically to individual projects and that timing of the action appeared questionable.
Other nations have raised similar concerns. Sweden announced it would approve two offshore wind farms while rejecting 11 others, citing security considerations. However, experts and officials from other countries have noted that technological solutions exist. The United Kingdom purchased new air defense radars to mitigate interference, while Denmark and other North Sea nations operate extensive offshore wind installations. Some defense experts have questioned whether the administration’s approach reflects legitimate security analysis or other priorities.
Criticism of the administration’s position comes from various quarters. Retired U.S. Navy Vice Admiral Dennis McGinn said there is no “showstopping national security issue” and suggested the administration is “maximizing the risks and costs of offshore wind while minimizing the benefits.” Democratic Senator Jack Reed, who participated in classified briefings, said he did not find the reasoning compelling. Legal expert Meghan Greenfield noted that applying national security arguments across numerous contexts has created skepticism among courts.
Supporters of the administration’s position argue that military assessments should be taken seriously and that dependence on foreign turbine manufacturers and the reliability of fossil fuels are valid considerations. The policy dispute reflects broader disagreements about energy policy and the balance between renewable development and defense priorities.
