A Miami-Dade County committee is evaluating a $101 million contract that would replace 25 aging explosives detection machines across Miami International Airport (MIA)'s North Terminal — equipment that manufacturers no longer service or support with software updates.

Why does Miami International Airport need new explosives detection equipment?

The 25 explosives detection system (EDS) machines currently installed across five security clusters in MIA's North Terminal have reached the end of their operational lifespan, leaving the airport running screening hardware that manufacturers will neither repair nor update. Without vendor support, the machines represent a growing vulnerability in one of the busiest cargo and passenger airports in the United States.

  • Twenty-five individual machines are affected, distributed across five distinct security screening clusters.
  • Manufacturer support — covering both physical servicing and software updates — has been discontinued for all existing units.
  • MIA ranks among the nation's highest-volume airports for both passenger traffic and air cargo operations.

What would the $101 million contract actually involve?

The proposed contract would fund a phased installation of next-generation screening equipment while the Transportation Security Administration (TSA) simultaneously decommissions the legacy machines, a sequenced approach designed to keep security lanes operational throughout the transition. The full project is expected to take approximately four years and eight months to complete.

  • Next-generation EDS units would be introduced in phases to avoid shutting down active security checkpoints.
  • The TSA would manage the decommissioning of outgoing machines in coordination with the installation schedule.
  • The timeline of roughly four and two-thirds years reflects the complexity of upgrading a terminal that must remain fully operational during construction.

What does this upgrade mean for travelers and airport operations?

For passengers moving through MIA's North Terminal, the phased rollout means security lane disruptions should be limited, as the project is specifically structured to minimize downtime at active checkpoints. The upgrade positions MIA with modern, manufacturer-supported screening technology for the foreseeable future, reducing the risk of unplanned equipment failures that could delay thousands of daily travelers.

  • Phased installation is intended to prevent full-lane closures during the multi-year project window.
  • Modern EDS units offer both updated threat-detection algorithms and ongoing manufacturer maintenance agreements.
  • The investment signals a broader infrastructure commitment at a facility that serves as a critical gateway for South Florida's economy.

Where does the approval process stand?

The $101 million proposal is currently before a Miami-Dade County committee for review and has not yet received final approval. A committee recommendation would typically precede a full county commission vote before any contract is formally awarded.
