Spencer Cox, the governor of Utah, toured Teal Drones headquarters in Salt Lake City, to learn about Teal’s operations, the company’s impact on the national aerospace and defense industries and opportunities and challenges facing Utah’s local defense industry. The visit was organized by the newly created Utah Aerospace and Defense Association (UADA).
“Teal is deepening its relationship with UADA to help accelerate the rebuilding of America’s defense industrial base, specifically for UAVs,” George Matus, Teal Drone founder and CEO said.
Teal is certified as “Blue UAS,” authorizing the company to provide equipment to the U.S. military. Teal is also one of three UAV manufacturers invited to participate in the U.S. Army’s Short Range Reconnaissance Tranche 2, designed to deliver a portable small uncrewed aerial system that can be used by army platoons for surveillance, reconnaissance duties and improving situational awareness.
UADA was established in 2022 to address challenges associated with innovation, entrepreneurship, workforce development and supply chains for companies in the aerospace and defense industries.
“For far too long, we have ceded the building of UAVs to China and other places,” the governor said. “We are bringing that back and Utah is at the center of that.”
A bill moving through the U.S. Congress would impose a five-year ban on United States government purchases of drones manufactured or assembled in China, reports The Associated Press. The measure reflects bipartisan concerns that the unmanned aerial vehicles (UAVs) made in China could facilitate Chinese spying on critical infrastructure.
Major commercial and consumer UAV-maker company DJI is based in Shenzhen, China. Many of its small, low-altitude drones are employed by local and regional government users in law enforcement, emergency response and surveying. The ban could affect police departments that rely on federal funds for equipment. In 2020, the Department of Homeland Security halted such grants for Chinese-made drones.
Chinese-made components, including GNSS receivers and inertial sensors, are not addressed in the bill, and the Pentagon has acknowledged that many components for non-Chinese-company drones are made in China.
While the ban wouldn’t go into effect until 2023, many federal agencies have already imposed temporary restrictions on the use of Chinese drones. The Interior Department had flown more than 11,000 drone missions before January, when the agency temporarily grounded its fleet of more than 500 DJI drones over cybersecurity concerns, according to The Hill. The Hill cites a May 6 Pentagon report. The report found no malicious code in the software for DJI’s Government Edition drones.
An analysis by Booz Allen Hamilton released in June 2020 found no evidence that DJI drones have shared sensitive information with the company or the Chinese Communist Party.
In August 2020, the Defense Department issued approval to drones from five companies:
Skydio’s X2-D. Skydio is based in Redwood City, California.
Parrot’s Anafi USA. While Parrot is based in Paris, France, the ANAFI USA drone is manufactured in the United States for U.S. customers.
Teledyne FLIR’s Flir M440 Ion. The drone was originally made by Altavian in Florida, which was acquired by FLIR in December 2020, which was subsequently acquired by Teledyne Technologies in January. Teledyne FLIR is headquartered in Wilsonville, Oregon.
Teal Drones’ Golden Eagle. Teal Drones is based in Salt Lake City, Utah.
Vantage Robotics’ Vesper. Vantage is based in San Leandro, California.
