  America’s F-22 stealth fighter may be limited in Asia-Pacific conditions, China’s J-20 designer says

  Aircraft has been sent to the region but was designed for combat in Europe, which could affect its capabilities, according to Yang Wei China's answer to the Raptor has yet to be put to the test in a real combat situation, military expert notes Minnie Chan Published: 12:00am, 30 Jul, 2020 America's F-22 Raptor stealth fighter was designed for combat in Europe but is now being used in the Asia-Pacific, according to a top Chinese aircraft designer, who says the different conditions will limit its capabilities there. Yang Wei, general designer of China's first stealth fighter the J-20, said the twin-engine F-22s could face the same challenges in the region as the F-4 fighter-bombers the Pentagon sent to the Vietnam war between 1965 and 1973. “The complex environment and political constraints in Vietnam caused the F-4 to almost fail to show its high-speed performance and over-the-horizon combat capabilities,” Yang wrote in a paper published in Chinese aeronautics journal Acta Aeronautica et Astronautica Sinica last month. He said the F-22, a tactical fighter inspired by the Cold War between the United States and the former Soviet Union, was designed for battle in Europe and could face similar problems now that it had been deployed in the Asia-Pacific. Yang did not draw any comparisons between America's F-22 and China's J-20 both fifth-generation, twin-engine heavy fighter jets and of a similar size. But military experts said his remarks indicated that the J-20 Weilong, or Powerful Dragon, was clearly seen as China's answer to the F-22. Comparing the two, Song Zhongping, a military commentator in Hong Kong, said the J-20's biggest advantage was that it was developed later, meaning its designers could learn from the F-22 – including how to fix shortcomings, and what type of new technologies could be used to optimise the aircraft. “The F-22 was originally designed for combat with the former Soviet Union, or today's Russia, in Europe, but now the Raptor's main opponent is the [People's Liberation Army] in the Asia-Pacific,” Song said. “China's J-20 was inspired by the F-22's deployment. The Chinese aircraft designers used the Raptor as a rival and the F-35 [stealth multi-role fighter] as a tactical opponent to help them to come up with a more practical and capable fighter jet.” Both the F-22 and the J-20 have a ceiling of 20km (12.4 miles) and a maximum speed of over Mach 2 (2,470km per hour, or 1,535mph) – faster than the speed of sound. The F-22 has a comparatively shorter range – with a combat radius of 800km (497 miles), while the J-20's large internal fuel tank can sustain a longer combat radius of 1,100km (684 miles). But Beijing-based military expert Zhou Chenming noted that the J-20, which entered service in 2017, had yet to be put to the test in a real combat situation. Andrei Chang, founder of influential military magazine Kanwa Asian Defence, said that in contrast, the F-22's combat capabilities had been seen, most recently last year when the stealth fighters were sent to Qatar as tensions rose with Iran. “The operation of the F-22 has been perfected since it joined the US military in 2005. The Raptor has taken part in countless actual combat situations around the globe, including in the Middle East, Singapore and Okinawa in the Pacific,” Chang said. A military source close to the PLA believed the J-20 could counter the F-22 in a one-on-one combat situation, but said far fewer of the fighter jets had been made compared to America's Raptors. “At the moment China has about 60 J-20s – just one-third of the total number of F-22s,” said the source, who requested anonymity due to the sensitivity of the matter. “Now the US has deployed hundreds of F-35s to the region, so it's an even bigger threat to China,” he added. With F-22s being deployed to the Asia-Pacific region – and as relations worsen with Washington, including over the disputed South China Sea – Beijing has stepped up development of its new stealth fighter. Mass production of the J-20B began earlier this month. https://www.scmp.com/news/china/military/article/3095219/americas-f-22-stealth-fighter-may-be-limited-asia-pacific

  Air Force gets new stopgap system for GPS 3 satellites

  By: Nathan Strout The U.S. Air Force's first next-generation GPS satellite launched in December and the second GPS III satellite is slated to liftoff in July. But there Air Force has a problem: The ground system currently in use isn't fully capable of controlling GPS III satellites. Worse, a new ground system that can, formally known as the next-generation operational control system (OCX), is five years behind schedule and won't be delivered until June 2021 at the earliest, according to the Government Accountability Office. Enter the GPS III Contingency Operations (COps) software—a critical stop gap measure that will update the current ground control system and allow it to access some of the more advanced features of the GPS III satellites until the next-generation operational control system is ready. On July 11, primary contractor Lockheed Martin announced that it had delivered the COps upgrade to the Air Force. “Positioning, navigation and timing is a critical mission for our nation and COps will allow the Air Force to gain early access to its new GPS III satellites,” said Johnathon Caldwell, Lockheed Martin's vice president for Navigation Systems. “We just finished final qualification testing and delivery on COps, and it will be integrated and installed on the [Architecture Evolution Plan Operational Control System] over the summer. We look forward to the Air Force ‘flying' a GPS constellation on the COps OCS which includes the new GPS III satellites, later this year.” The new GPS III satellites are built to be more robust and accurate than their predecessors and come with advanced features such as the ability to use M-Code, an encrypted GPS signal for use by the military. The COps upgrade will allow the current ground system to control the GPS III satellites as well as the legacy GPS satellites. It will also allow the current system to access M-code Early Use, an encrypted GPS signal with improved anti-jamming and anti-spoofing capabilities, beginning in 2020. The Air Force contracted with Lockheed Martin to deliver the patch in 2016, the same year that the OCX program triggered a Nunn-McCurdy cost breach—a type of violation caused by significant cost growth that requires a program to be shut down unless the Department of Defense intervenes and approves a new cost estimate. The $6.2 billion OCX program is already five years behind schedule, and a May 21 Government Accountability Office report warned that the OCX program could be delayed even further. In addition, the Air Force has acknowledged that delays are possible during the seven-month testing period following delivery. Raytheon, the primary contractor behind OCX, rejected the GAO report, claiming that its findings were inaccurate. https://www.c4isrnet.com/battlefield-tech/c2-comms/2019/06/11/air-force-gets-new-stopgap-system-for-gps-3-satellites/
