The TSA and FBI are conducting tests at the Redstone Arsenal in Huntsville to replicate explosives from current terror threats and evaluate detection technologies. They are focusing on understanding the chemistry behind explosives and devices, using the latest CT scanners to identify potential threats like 3D-printed guns. This year, over 6,000 weapons have been detected, marking a record. However, it will take until 2042 to equip all airports with the best scanners. A top priority is addressing explosives found at DHL cargo facilities in Europe, believed to be planted by Russian agents. Experts are recreating explosive mixtures to analyze chemical signatures and improve detection systems. The molding of explosives can significantly impact their destructive capability, as demonstrated by tests showing different outcomes based on molding techniques. The FBI is also addressing the challenge of 3D-printed firearms, which are as lethal as traditional IEDs, by deploying handheld detectors to stay ahead of emerging threats.
