Trump Cites National Security to Halt Offshore Wind Development

The Trump administration has moved to halt offshore wind development, citing national security concerns that have been a focus since late last year. The administration has paused major projects and is repurchasing leases, asserting that offshore wind poses a threat to national security. Interior Secretary Doug Burgum pointed to a classified report from Defense Secretary Pete Hegseth as evidence, claiming it proves offshore wind is a national security risk.

This stance emerges amid President Trump's known opposition to wind turbines and his administration's push for fossil fuels to achieve "energy dominance." National laboratory estimates indicate that offshore wind farms along U.S. coasts could generate more than enough electricity to meet the nation's annual consumption. Acknowledging that wind turbines can interfere with radar, the Pentagon already reviews construction plans and can designate restricted areas. Furthermore, upgrades to radar systems are available to mitigate these impacts.

Concerns raised include the potential for spinning turbine blades to create false targets on radar screens. Burgum specifically mentioned worries about autonomous drones potentially navigating through wind tower fields undetected due to radar interference. He also suggested that the vibration from wind towers could affect undersea sonar. According to the Department of Energy, radar systems can be adjusted to increase the detection threshold, potentially leading to missed targets.

Kirk Lippold, a national security expert and former commander of the USS Cole, noted that radar operators are trained to distinguish between actual targets and background clutter. He stated that if drones are not detected before reaching a wind farm, "we have bigger national security issues." The Department of Justice reported that defense officials provided the Bureau of Ocean Energy Management with classified information in November 2025 detailing new risks associated with offshore wind projects near East Coast cities, leading to the halt of five major projects.
