Trump order forces 90‑day halt of five East Coast offshore wind projects over security concerns
The Trump administration ordered an immediate, at‑least‑90‑day pause on construction‑phase leases for five East Coast offshore wind farms — Vineyard Wind 1, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind and Empire Wind — citing classified Defense Department assessments that recent adversary technological advances and turbine radar “clutter” could pose national security risks. BOEM acting director Matthew Giacona sent letters directing developers to suspend work while Interior, the Defense Department and other agencies assess whether those risks can be mitigated (the pause can be extended), a move critics and industry groups say conflicts with prior DoD reviews that raised no objections and comes amid broader legal and political battles over offshore wind.
📌 Key Facts
- The Interior Department ordered an immediate pause on construction‑phase offshore wind leases and sent BOEM letters directing five large East Coast projects to suspend activities for at least 90 days; the pause can be extended.
- The five projects identified for the suspension are Vineyard Wind 1 (Mass.), Revolution Wind (R.I./Conn.), Coastal Virginia Offshore Wind (Va.), Sunrise Wind (N.Y.) and Empire Wind (N.Y.).
- The administration cites recently completed classified Defense Department/Pentagon assessments that warn of national security risks — including turbine-related radar “clutter” that could obscure or create false targets — and describe a “rapid evolution of relevant adversary technologies” posing “serious, immediate and irreparable harm.”
- Interior officials say the 90‑day pause is intended to give DOI, the Defense Department (referred to in some documents as the Department of War) and other agencies time to work with leaseholders and state partners to assess whether the identified national security risks can be mitigated; Interior Secretary Doug Burgum warned large‑scale offshore wind near East Coast population centers could create vulnerabilities.
- Acting BOEM Director Matthew Giacona signed the suspension letters; Giacona is a former National Ocean Industries Association lobbyist, and House Democrats are seeking an ethics investigation into potential overlap with his previous lobbying work.
- Industry and some lawmakers contend the Defense Department previously reviewed the projects with no objections: NOIA president Erik Milito said every project under construction cleared DoD review, and Rep. Joe Courtney pointed to a 2023 DoD Record of Decision and a December 2024 Pentagon letter saying Revolution Wind would not adversely affect DoD missions.
- National security critics, including retired Navy Cmdr. Kirk Lippold and other experts, have publicly questioned the administration’s rationale — asking what threat environment has changed and noting offshore wind can enhance energy diversification and resilience.
- The pause comes amid broader legal and political battles over wind power: a federal judge recently vacated a prior Jan. 20 anti‑wind executive order as “arbitrary and capricious,” and Congress has been considering legislation (the amended SPEED Act) that would let the administration exclude projects it flags, a change that prompted the American Clean Power Association to withdraw support; local opponents (e.g., Protect Our Coast NJ) hailed the pause as a win for fishermen and ratepayers.

- BOEM letters to developers explicitly direct five large-scale East Coast offshore wind projects under construction to suspend activities for at least 90 days, with the pause extendable.
- The letters state Interior will use the 90-day period to work with developers to assess whether national security threats from the projects “can be adequately mitigated.”
- The letters cite a recent classified Defense Department assessment describing a “rapid evolution of relevant adversary technologies” and warning of “serious, immediate and irreparable harm” to national security from the projects’ East Coast locations.
- The article identifies Matthew Giacona, a former National Ocean Industries Association lobbyist, as the acting BOEM director who signed the letters, and notes House Democrats are seeking an ethics investigation into potential overlap with his prior lobbying work.
- Retired Navy Cmdr. Kirk Lippold publicly questions the administration’s rationale, saying he is unaware of any change in the threat environment that would justify stopping offshore wind programs and asking what “threat vector has changed.”
- PBS specifies that the paused leases concern five large-scale offshore wind farms off the East Coast.
- The report emphasizes the Pentagon's belief that the turbines could obscure and confuse radar signals as the operative security rationale.
- Frames the move explicitly as the latest in a broader series of Trump administration actions targeting wind power.
- Interior’s press release language says the pause applies to 'leases for all large-scale offshore wind projects being constructed in the United States,' confirming scope as nationwide and specifically tied to construction-phase projects.
- The Department of the Interior states the pause is based on 'national security risks' identified by the Department of War in 'recently completed classified reports.'
- Interior says the pause is intended to give DOI, the Department of War and 'other relevant government agencies' time to work with leaseholders and state partners to assess whether those national security risks can be mitigated.
- Confirms Interior’s pause is effective immediately and explicitly framed as a response to 'emerging national security risks' and 'rapid evolution of relevant adversary technologies.'
- Provides a direct quote from Interior Secretary Doug Burgum explaining that large-scale offshore wind near East Coast population centers could create vulnerabilities.
- Details that Interior cites unclassified U.S. government reports about radar 'clutter' from turbine blades and towers creating false and obscured targets.
- Notes that the pause comes two weeks after Judge Patti Saris vacated Trump’s Jan. 20 executive order blocking virtually all federal wind leasing as 'arbitrary and capricious.'
- Includes criticism from national security expert and former USS Cole commander Kirk Lippold, who argues DoD was consulted throughout permitting and that offshore wind can benefit national security by diversifying energy supply.
- Interior’s announcement specifies that the lease pause applies to offshore wind projects that are already under construction, citing 'national security risks' identified by the Department of War in recently completed classified reports.
- Interior publicly identifies five affected Atlantic Coast projects: Vineyard Wind 1 (Massachusetts), Revolution Wind (Rhode Island/Connecticut), Coastal Virginia Offshore Wind, Sunrise Wind (New York) and Empire Wind (New York).
- National Ocean Industries Association president Erik Milito states that every project under construction has already undergone Department of Defense review 'with no objections,' and Rep. Joe Courtney cites a 2023 DoD Record of Decision and a December 2024 Pentagon letter saying Revolution Wind would not adversely affect DoD missions.
- The article links the pause to a broader policy and legal context: a federal judge threw out Trump’s earlier January anti‑wind order roughly two weeks ago, and the House‑passed SPEED Act was amended to let the administration exclude projects it has 'flagged for reconsideration,' prompting the American Clean Power Association to withdraw support.
- Protect Our Coast New Jersey and its president Robin Shaffer hail the pause as a 'Christmas gift' and frame it as a win for local fishermen and ratepayers opposed to offshore wind.
