A new report by the House Homeland Security Committee has found that a majority of U.S. airports do not implement “full employee screening” at access points and that conflict between government and industry stakeholders hampers efforts to build up aviation security.

The report titled “America’s Airports: The Threat From Within” is the product of a two-year investigation carried out by House Transportation and Protective Security Subcommittee Chairman John Katko (R-New York), the House panel said in a news release published Monday.

The document stated there are inconsistencies in the way air carrier and airport security officials train employees when it comes to responsible use of access and suspicious activity reporting.

The report also cited several examples of insider threats at airports such as drug and gun smuggling, attempt to detonate a bomb and employees’ involvement in terrorist activities abroad.

The House subpanel offered nine recommendations to mitigate risks of insider threats within the U.S. aviation sector and one of those is the call for the Transportation Security Administration and airports to review credentialing practices to ensure that airport employees adhere to stringent standards.

The Department of Homeland Security should collaborate with airports to find technology platforms designed to ensure security of employee access, the report added.

The U.S. Marine Corps looks to implement a rifle-mounted laser range finder in 2018 as part of efforts to help the service branch’s infantry squad leaders call in air strikes and artillery fire when they perform missions, C4ISR and Networks reported Sunday.

Shawn Snow writes the Marine Corps Systems Command currently conducts a market research and plans to invest $16 million to procure 1,800 laser range finders.

The technology is designed to help users access information on distances and locations of targets that can be engaged with heavy fire.

“The Marine Corps desires a smaller and lighter range finder for use in the infantry squad as it will be mounted on [the M4] and minimizing any addition to the individual combat load is always a prime consideration,” a MARCORSYSCOM representative was quoted as saying by C4ISR and Networks.

Snow noted that fielding new laser range finders may transform the approval process of air strikes or artillery fire missions, which he said currently goes through the joint terminal attack controller process.

The U.S. Air Force has begun to test upgrades for Northrop Grumman-built B-2 stealth bombers that include new sensors, software, electronics and radar technology, Scout Warrior reported Monday.

Kris Osborn writes the B-2 defensive management system has been updated to help  sustain the bomber’s stealth functions and increase defense against new threats.

Capt. Michael Hertzog, an Air Force spokesman, told Scout Warrior the DMS-M system will work to support B-2’s capacity to counter 21st century threats.

The report said the DMS-M program obtained authorization last year to move into the engineering manufacturing and development phase of the acquisition process.

Hertzog added three aircraft will be updated to complete the EMD phase and the program is scheduled to enter full rate production in 2019, according to the report.

The service branch expects to spend nearly $1.84 billion to build four B-2 DMS-M units and looks to invest $832 million to procure an additional 16 units, Osborn wrote.

The Air Force will fly B-2 aircraft alongside the B-21 Raider stealth bomber, which is scheduled to enter service by the mid-2020s.
