The Science and Technology Directorate (S&T) has always placed a special focus on aviation security. That’s one of the reasons why the work that is being done by S&T’s Next Generation (NextGen) Explosives Trace Detection (ETD) program team is such a high priority.
The sophisticated research, development, testing and evaluation (RDT&E) that S&T performs is changing the scientific and security landscape. In coordination with government, academic, and industry partners, S&T is relentlessly committed to helping bring a variety of cutting-edge solutions to the field.
Launched in fiscal year 2020, NextGen ETD expanded the scope of a previous program to meet evolving operational needs at aviation checkpoints.
