"[The MDA] has designated the Center for Security Forces Detachment Kittery Survival, Evasion, Resistance and Escape Facility (SERE East), Redington Township, Maine as an Alternative… Not Carried Forward for a potential additional missile interceptor site," the statement said on Friday.
The SERE site in Maine presented "irreversible environmental impacts, significant constructability concerns, and extensive costs" associated with developing infrastructure in a remote area, the MDA explained.
"Due to these factors, and in accordance with the National Environmental Policy Act process, the SERE East site will not be carried forward for further consideration," the statement noted.
Previously announced sites in the US states of New York, Ohio and Michigan will continue to be considered, according to the MDA.
The US government currently operates anti-ballistic missile sites in Alaska and California to protect the continental homeland from ballistic missile attack by countries such as North Korea and Iran, the MDA noted.
