#  Vehicle Blocker

 Written by Gwyn Winfield on 27 October 2021.

Block MEMS, LLC (Block) has been awarded a $2.6 million contract in support of the U.S. Department of Homeland Security's Science and Technology Directorate (S&T) to detect Vehicle-Borne Improvised Explosive Devices (VBIEDs). The focus of the program is to detect vehicles containing VBIEDs before they enter stadiums, office building parking structures, and other "soft targets." Block's technology is able to detect trace explosives at a standoff distance of up to five meters.

The program will build on Block's next generation quantum cascade laser (QCL) technology, which was funded by the Intelligence Advanced Research Projects Activity (IARPA) \[See [Music of the Ainur](https://cbrneworld.com/magazine/archive/the-music-of-ainur), CBRNe World, February 2018, Ed.\]. Dan Cavicchio, Block's CEO, stated that, "We are grateful for the opportunity to partner with S&T to develop and commercialize the technology for detection of Vehicle-Borne IEDs. Block's infrared laser technology will help to identify vehicle-borne explosives before they enter an underground parking garage or stadium parking facility." During the past ten years, improvised explosive devices have injured or killed over 150,000 people worldwide. Over 50,000 of these people were the victims of Vehicle-Borne IEDs.
