The Hidden Metal Cost of a Global Rearmament Cycle
G7 nations are committing $8 trillion to military expansion, creating a surge in demand for critical minerals that mirrors the growth of the artificial intelligence sector.

In the wake of a tragic incident and mounting safety concerns, Transportation Secretary Sean Duffy has laid out a bold vision for overhauling the United States’ air traffic control (ATC) system by 2028.
This multi-billion dollar initiative comes not a moment too soon, as the nation’s aviation infrastructure shows signs of buckling under the weight of outdated technology and increasing air traffic demands. The impact of outdated technology in aviation is significant.
The urgency of this overhaul is underscored by a deadly collision earlier this year between an Army Black Hawk helicopter and a passenger plane at Reagan National Airport.
The crash, which took 67 lives, has been seen as a grim illustration of the systemic failures that Duffy’s plan aims to address. Aviation safety recent incidents further highlight the need for reform.
Recent outages, such as the 90-second blackout at Newark Liberty International Airport due to a frayed copper wire, further highlight the precarious state of the current system.
Such incidents are not merely inconvenient; they are potentially catastrophic.
Duffy’s initiative seeks to replace the aging infrastructure with a state-of-the-art system, swapping out 1960s-era facilities with six new air traffic control centers. The plan also includes upgrading from copper wiring to modern fiber-optic, wireless, and satellite technologies across 4,600 locations.
The initiative calls for the replacement of 25,000 radios and 618 outdated radars.
The financial details remain somewhat opaque, with Duffy suggesting a cost in the “tens of billions” of dollars, while a House Committee has floated a $12.5 billion proposal.
The Trump administration has already earmarked $4 billion for initial updates by 2026.
The current ATC system, reliant on technology that dates back half a century, has been described by Duffy as akin to using a flip phone in a smartphone era.
As air traffic has grown, the system designed to manage it has remained static, struggling under the pressure of up to 50,000 daily flights at U.S. airports.
The stark reality is that without significant upgrades, the frequency of telecom outages—currently around 1,000 per week—will only increase.
President Trump has thrown his support behind the overhaul, emphasizing the need for a single, comprehensive contract to modernize the system.
His administration’s push for reliable service is part of a broader commitment to infrastructure improvements, which includes the establishment of 174 new weather stations in Alaska.
Duffy’s vision isn’t just about replacing hardware; it’s about reimagining how air traffic is managed in an era of rapid technological advancement.
The plan encompasses software updates and a new flight management system, which is set to include electric air taxis, or eVTOLs. Often referred to as “Ubers in the air,” these vehicles are part of a forward-thinking approach to future-proof the ATC system.
The announcement has been met with cautious optimism.
Acting FAA Administrator Chris Rocheleau and Nicholas Calio, CEO of Airlines for America, have both praised the initiative.
Calio, who has long advocated for modernization, expressed relief that antiquated technologies like floppy disks and paper strips will soon be relics of the past.
His organization is pushing for an additional $18.5 billion in emergency funds to expedite the overhaul.
This ambitious plan, however, is not without its challenges. Implementing such a wide-ranging transformation within a tight timeframe will require unprecedented coordination between government agencies and private contractors.
Congress will need to approve significant appropriations, and stakeholders across the aviation industry must collaborate closely to ensure a seamless transition. For travelers, airlines, and aviation professionals, Duffy’s plan offers a glimmer of hope for safer, more reliable air travel.
The stakes are high, but the potential rewards—measured in lives saved and flights safely completed—are immeasurable.
As the U.S. gears up for this monumental task, the world will be watching, hopeful that this overhaul will set a new standard for aviation safety and efficiency in the 21st century.
