The US Department of Homeland Security (DHS) has approved $56m in funding for three airports in a bid to enhance and strengthen security at the facilities.
Charlotte Douglas International Airport will receive $45.4m to install a new inline baggage screening system at its main terminal.
The advanced screening system, equipped with on-screen resolution capabilities, will quicken baggage screening and streamline the ticketing process.
St Louis International Airport will receive $3.1m for the installation of an upgraded inline baggage screening system at terminals 1 and 2.
Orlando International Airport will receive $7.5m to expand its CCTV system with several hundred cameras to enhance its surveillance capabilities.
DHS secretary Janet Napolitano said the enhanced screening and surveillance systems will strengthen the ability to detect and disrupt threats of terrorism.
