Land Along Southern Border Is Transferred to Navy to Become Part of ‘National Defense Area’
13th December 2025
The Trump administration said on Dec. 10 that it would transfer roughly 760 acres of public land along the U.S.-Mexico border in California to the Navy for three years to support border security operations.
While announcing the decision Wednesday, the Interior Department said the land would become part of a “National Defense Area,” or militarized zone, to bolster immigration enforcement.
The land stretches from roughly a mile west of the California-Arizona state line to the western edge of the Otay Mountain Wilderness Area in San Diego and Imperial counties, according to the Interior Department.
