The expansion of autonomous surveillance towers will come at a cost of $1 billion to the American taxpayer, funds that were originally allocated under Trump's Big Brother Bill.

In June, the Government Accountability Office (GAO) released a new report that detailed how the Department of Homeland Security (DHS) has contracted with Anduril Industries—a Peter Thiel-funded company—to nearly triple the number of surveillance towers along US borders. The report outlines the plan to increase the number of surveillance towers from 830 to 2,300 by 2034.

The new GAO report describes the "Integrated Surveillance Towers" (IST) program that currently consists of "803 fielded towers located along US borders that detect items of interest, such as people or vehicles."

The IST program includes towers from four legacy systems, including Autonomous Surveillance Towers (AST). An AST is a solar-powered surveillance tower that the DHS says can "provide autonomous surveillance operations 24 hours per day, 365 days per year." The towers are equipped with radar, optical, and thermal cameras.

According to the GAO report, in August 2024, DHS approved the purchase of up to 42 additional ASTs. DHS had previously approved Customs and Border Protection's (CBP) request to purchase up to 133 additional towers between 2022 and 2023. The report states that the program should be completed by March 2034, with 2,300 deployed by that date.

The GAO was established in 1921 to serve as an independent and nonpartisan agency that audits the federal government. The GAO releases annual reports on key issues and details its findings to Congress.

The Electronic Frontier Foundation, a non-profit dedicated to digital privacy and rights, called the expansion of border surveillance a "digital dumpster fire for human rights and civil liberties."

"It's not just surveillance towers; drones, aerostats, surveillance vehicles, ground sensors, game cameras, and license plate readers are also part of the vast taxpayer-funded infrastructure that threatens all those who live, work, or seek refuge in the borderlands," the EFF wrote in response to the GAO report. "This technology isn't exclusive to U.S. federal agencies: it's also deployed by state and local law enforcement, and even by governments on the Mexican side."

The EFF also noted that these rapidly expanding surveillance technologies place residential neighborhoods in Arizona within the sight of the towers, making them "capable of spying on homes on both sides of the border."

Anduril Industries and the Surveillance Lattice

The GAO report notes that the contract for construction of the Autonomous Surveillance Towers went to Anduril Industries.
