“Wind turbines within the line of sight of Early Warning Radar (EWR) disrupt these systems used for early threat detection and military surveillance. As depicted in Figure 1, all three of the projects under construction (Revolution, SouthFork, and Vineyard Wind) will significantly interfere with the EWR system. Interference can hinder ballistic missile airspace surveillance, confound target detection, and prolong response time to attacks.”

“Nonetheless, the presence and layout of large numbers of WTGs [wind turbines] could make it more difficult for SAR [search and rescue] aircraft to perform operations (of people or marine mammals), leading to less effective search patters or early abandonment of searches. This could result in otherwise avoidable loss of life due to maritime incidents.” page 3.17-8.

“The EWR screening analysis results show that wind turbines in the northern corner of the study area will be within line-of-sight of the Cape Cod AFS EWR at a blade-tip height of 808 feet AGL. At a blade-tip height of 1,067 feet AGL, wind turbines in the northern one-half of the study area will be within line-of-sight of this radar site. See Figure 5.

Research conducted by Westslope suggests that wind turbines in the study area within line-of-sight of the Cape Cod AFS EWR could have a significant impact on this early warning radar. [1]”
