Rafael hopes quantum technology can help in GPS-denied environments
Rafael Advanced Defense Systems has been investing in quantum technology in the hopes that it will improve existing sensors on the battlefield and could lead to a solution for GPS-denied environments.
Because the technology is linked to better positioning, navigation and time-keeping, company leaders said they believe it could “revolutionize” this space. Alternative means of PNT have become a priority for militaries throughout the world as jammers become less expensive and more ubiquitous while the reliance on PNT information increases.
In particular, Rafael executives are encouraged that “extremely high-performance quantum accelerometers and gyroscopes can be designed to be the basis of the next generation inertial navigation systems,” a company official said. These sensors can exploit the quantum properties of atoms to measure acceleration and angular rates with unprecedented accuracy, which, in turn, allows for “dead-reckoning navigation for relatively long periods of time while essentially keeping GPS/GNSS accuracy.”
Rafael's team working on quantum technology, which includes Alon Gabbay, head of miniature quantum sensors group of the Manor division and Nitzan Link, of the CTO Technology Center of the Manor Division of Rafael Advanced Defense Systems, were among those who discussed the potential for the technology with Defense News.
Quantum technology is about sensors that “measure discrete energy levels and difference in change with magnetic or electric fields,” a Rafael official said. The struggle for engineers has been that while this technology has existed for decades, particularly in university labs, miniaturizing it and using it in defense systems is a challenge.
While Rafael is traditionally Israel's research and development arm for new weapon systems, it is also the company behind the Trophy defense system, Litening targeting pod and Iron Dome air defense technologies. Rafael has also rolled out new digitized battlefield concepts and used optics to better match scenes and leverage artificial intelligence.
“Quantum technologies can give rise to ultra-sensitive gravitational and magnetic measurements, hence opening the possibility of using anomaly maps to aid inertial navigation,” a company official told Defense News. “Atomic clocks use quantum technologies to provide highly stable and accurate frequency standards; the resulting technology can be used for time-keeping opening new possibilities for using communications as an aid to an integrated navigation system.”

Lockheed looks to sell additional F-16s to customers in Africa, Asia and South America
By: Valerie Insinna WASHINGTON — Lockheed Martin anticipates another wave of international F-16 sales, with countries from Africa, South America and Southeast Asia among those interested in purchasing the jet, the company's chief financial officer said Tuesday. “I think this is a good fourth-generation aircraft for those customers that can't afford the F-35 or, frankly, can't at this time buy the F-35,” Lockheed CFO Kenneth Possenriede told investors during an April 21 earnings call. “It might be a good intermediary step for customers to go from the F-16 to F-35. So we see it frankly as complementary and not competing against themselves.” Unlike the F-35 program, which is seeing disruption within its supply chain that could delay future deliveries, the F-16 production line has experienced little impact as a result of the coronavirus pandemic, Possenriede said. The company moved production of the F-16 production line from Fort Worth, Texas, to Greenville, South Carolina, in 2019 to accommodate production of 16 Block 70 aircraft for Bahrain. Since Bahrain's order in 2018, Lockheed has garnered contracts for eight F-16s for Bulgaria, 14 aircraft for Slovakia, and is working with the U.S. government on a sale of 66 jets for Taiwan. “We also have a couple of orders for F-16 that we're working to try to shape,” Possenriede said. “There is an African country that is interested in F-16, so we're hopeful that will happen. [There is also a] South American country, and then there are some Southeast Asian countries that are interested in F-16 as well.” Possenriede didn't detail which nations were considering purchases of the F-16, as defense companies typically wait until international militaries publicly declare their interest in a sale before talking about specific customers. Richard Aboulafia, an aerospace analyst with the Teal Group, said there's a “pretty good chance” that some of those orders materialize. “Lockheed was doing a disservice by forgetting the F-16 program for so many years. They had this idea that the future was F-35 and nothing but F-35, ignoring the part of the market that is not prepared to buy the F-35 price tag,” he said. “It's actually a really good franchise with a really solid core market. It seems ill-advised to neglect it.” If a new customer in Africa is looking to buy F-16s, it could be Botswana, which has indicated an interest in buying fighter jets, Aboulafia said. Lockheed has already sold F-16s to Morocco and Egypt, and the U.S. State Department in 2019 cleared Morocco for new F-16s and upgrades. In South America, Lockheed has been trying to sell F-16s to Argentina for years, but Aboulafia believes a second order for Chile is a more likely prospect. In Southeast Asia, a sale to Indonesia “would seem to be one of the most likely possibilities,” he added. https://www.defensenews.com/global/mideast-africa/2020/04/22/lockheed-looking-to-sell-additional-f-16s-to-customers-in-africa-south-america/
