Military Contractor's Spy Aircraft Quietly Flying Southern Border On Mysterious Mission

The Pentagon says it does not discuss contractor support to particular missions. The gear aboard mimics cell towers.

Private military contractor Metrea has spent months quietly operating two surveillance-equipped aircraft along the U.S.-Mexico border, according to the Arizona Mirror.

The planes have traversed Arizona, New Mexico and Texas, circling at high altitude over border cities including Bisbee and Douglas in Arizona, and Laredo and El Paso in Texas.

Metrea holds multiple contracts with the U.S. military, including a $5.7 million award to support training for U.S. Special Operations Command. The company also conducts simulated training missions for the Marine Corps.

It performs comparable border work overseas, providing what it describes as advanced aerial surveillance to the Australian government for monitoring that country's border regions.

Arizona Mirror reports:

One of the major pieces of equipment installed on the aircraft is a DRT 3300, also sometimes referred to as a "dirtbox." A dirtbox is a piece of equipment that mimics a cell phone tower and acts in a similar manner to "stingray" devices that track cell phones and reportedly can even intercept messages.

It isn't the only equipment on the aircraft meant for "signals intelligence" either. Signals intelligence refers to the collection of information that is transmitted through the airwaves such as radio, wifi or other electronic means. One of the aircraft lists a "Windjammer System" as a piece of equipment that has been installed.

The Trump administration declined to say what the aircraft are doing over the border, or which agency they are working for.

A DHS spokesperson told the Mirror that Immigration and Customs Enforcement, Homeland Security Investigations and Customs and Border Protection were not flying with Metrea along the southern border. The department did not answer whether the flights support a DHS or a Defense Department mission.

"The Department of War contracts with a number of companies, including Metrea, to provide capabilities in support of military operations across the globe. For operations security reasons, we do not discuss specific contractor support to particular missions or operations," a Defense Department spokesperson wrote in a statement to the Arizona Mirror. "These activities are governed by Attorney General approved procedures that ensure the activities are conducted in a manner that protects the constitutional and legal rights and the privacy and civil liberties of U.S. citizens."

Metrea did not respond to repeated requests for comment. Meanwhile, Metrea's are not the only contractor aircraft working the border. The Mirror reports that a jet belonging to Tenax Aerospace, equipped with high-end mapping technology and previously spotted over the South China Sea and Nigeria, has flown the same route since July.

Civil liberties advocates contend that the secrecy itself is the problem.

"Whatever security rationales are used to justify mass surveillance, whether it is patrolling the border or pursuing the war on drugs, if you're intent on pursuing those policies you have to do it in a way that respects the privacy and constitutional rights of Americans," said Jay Stanley, a senior policy analyst with the American Civil Liberties Union's Speech, Privacy and Technology Project, in a statement to the Arizona Mirror.

"Number one, you need policies that ensure transparency so we know what government agencies are doing with the brand new powers that technology is giving them that humans have never had in history," Stanley added. "No matter what your position is, you should agree that it is done in the democratic process and not done by government officials behind closed doors."
