LE BOURGET, France — As a number of companies chase maintenance work for the F-35 fighter jet, one firm is planning to clean up on the F-16.
AAR Corp., a provider of global aftermarket aviation services, won a seven-year contract with the Royal Danish Air Force to perform maintenance, repair and overhaul, or MRO, of Pratt & Whitney F100-220 engine components on the General Dynamics F-16 jet.
That win, which came earlier this year, is the latest contract in a long-term relationship supporting the Danish Air Force and air forces across Europe with MRO services from the company's repair facility in Amsterdam. That facility supports about $500 million in business, much of it tied to the F-16.
But the win also fits well into a grander ambition of the company, said Brian Sartain, senior vice president of repair and engineering services at AAR.
“Everybody is running after F-35 capability,” he said. “But the Danish Air Force is still going to have a lot of F-16s for [the] foreseeable future, and there are still a lot of F-16s being flown around the world.”
Sartain pointed to “fairly high-publicized” F-16 maintenance requirements coming down the pike for the U.S. Air Force, which reported a 65-70 percent mission-capable rate for F-16s in 2017. AAR has a facility in Duluth, Minnesota, which is located across the airfield from Duluth Air National Guard Base — home to the 148th Fighter Wing and its F-16C Fighting Falcon aircraft.
“Our facility is a perfect place to do F-16 maintenance. We have a lot of capacity,” Sartain said. “We're three tiers down in the F-35 component chain in the way those are being bid. We're not interested. So, while others are running after the F-35, we're cleaning up on the F-16s, and we're happy to do that.”
Beyond its F-16 work, AAR supports airframe maintenance for the P-8A fleet for the U.S. Navy, Australia and Foreign Military Sales customers. AAR and Boeing were each awarded seven-year indefinite delivery, indefinite-quantity contracts from Naval Air Systems Command in February 2018, competing each year on workshare. While Boeing performed the majority of work the first year, AAR was recently awarded the larger slice for 2019.
“Frankly, we're moving to majority share because our performance has been better,” Sartain said. “Most program competitors will need to sub tier to another company and then stack profit on top of profit. For government, it's a better value for us to be a prime, and for us it's a great opportunity to be a prime.”
AAR supports the P-8 work from its Indianapolis facility, where at any given time four P-8s are in the hanger, with two steady lines of maintenance. The location is also used to support maintenance of Southwest Airlines 737 aircraft, which share the same airframe as the P-8. It's gone from about 20 percent military and 80 percent commercial maintenance to an even split.
“Southwest asks that airplanes are returned in about 21 days. For the P-8, the Navy allows 60 for turnaround,” Sartain said. “The airplane comes in, we have a small crew of 30-40 that hold secret clearances and lock in a room the top-secret equipment, and then I can flex mechanics from Southwest to take advantage of that experience."

BY PATRICK TUCKER A research team is training computers to find and fuse clues from wildly different rivers of digital data. Hiding illicit nuclear programs might be getting harder, thanks to new ways of gleaning and combining clues from various rivers of digital data. That's the conclusion of new research funded in part by the U.S. Energy Department's National Nuclear Security Administration. Satellites offer one kind of information; social media another — particularly inside countries that may be trying to flout inspections. But large volumes of satellite imagery and social media data aren't similar. You can have one analyst examine satellite pictures and another look at social media posts to see if they align, but the process is time-consuming and generally far from comprehensive. The study's authors developed a method for fusing different types of data in a machine-readable way to offer a much clearer picture. “In light of their ubiquitous emergence, social media increasingly promise to be of great value even though associated applications have thus far remained simple, and their fusion with other data has been largely ad hoc,” the team from North Carolina State University writes in “Fusing Heterogeneous Data: A Case for Remote Sensing and Social Media.” Only by creating a new statistical method for fusing the outputs of satellite data and social media data do you get something you can use to predict what might happen next within a given area of interest, such as a specific nation's nuclear enrichment or weapons development. The researchers looked at satellite and social media data from August 2013, when deadly floods killed eight people and caused widespread damage in Colorado. They sought to show that if you could algorithmically identify which imagery showed the flooding from space, and which geotagged tweets described it on the ground, you could could much more quickly verify one data set against another — that is, you could determine whether incoming social media data supports the conclusions you might be reaching from your satellite data, and vice versa. “Next steps for the project include evaluating nuclear facilities in the West to identify common characteristics that may also be applicable to facilities in more isolated societies, such as North Korea,” notes a press release on the paper. One of the authors, NCSU computer and electrical engineering professor Hamid Krim, said the team would try to “address the insufficient knowledge in general in areas of great interest (e.g. N. Korea and Iran). The goal is to come up with systematic methodologies to transport knowledge about nuclear environments available in other areas (e.g., in the West) to these domains where there is very little available. Creating such an environment in these places of interest will help them detect potential undesired activity.” Of course, there are limitations to media monitoring in Iran and North Korea. The former's social media environment is largely underground, thanks to bans on Twitter and many other social networks. The latter has virtually no social media environment at all. Krim noted that the “adversarial strategy” of social-media censorship makes his team's analysis harder. But even social posts from nearby countries can help illuminate their more secretive neighbors, he said — think tweets from Japan after earth tremors are felt. https://www.defenseone.com/technology/2018/07/satellite-imagery-social-media-new-way-spot-emerging-nuclear-threats/150146/
