  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

  New Tool Developed to Improve Pilot Visibility

  8/14/2020 By Connie Lee Special Operations Command and the Army are adopting new technology to improve visibility during flight operations in degraded conditions. Sierra Nevada Corp. was selected for the third phase of the degraded visual environment pilotage system competition following a 2015 airborne test. The company's most recent contract modification includes full-rate production, according to a company news release. Paul Bontrager, Sierra Nevada's vice president for government relations, said the system will help pilots operate in areas with limited visibility such as fog and dust. “We've always had a hard time flying in snow and flying in dirt,” he said. “In Army aviation we've been waiting for this technology to mature, and it has.” To enable pilots to maintain their situational awareness, the product has multiple features such as cameras and radars, he said. The system also has light detection and ranging. By combining sensors, a pilot is able to see a more accurate picture of the surrounding environment. Additionally, there are different versions of the system with varying amounts of sensors, he noted. Sierra Nevada can take data from multiple sensors and fuse the imagery onto a screen, he said. “A camera can do so much,” he said. “But then a lidar can actually paint the landing area and give a lot of detail about the surface.” The military has often had to fly in challenging operating environments, he noted. In the Middle East, pilots would often experience “brown out,” which occurs when visibility is impacted by dust and sand which has resulted in crashes, he said. “When we got embroiled in the wars in Iraq and Afghanistan, it was a significant thing,” he said. “We actually had more losses in the more recent years when it wasn't direct combat operations. We have more losses annually due to flying into planet Earth unintentionally than we do from enemy fire.” The degraded visual environment pilotage system is likely to be used in Army Chinooks and Black Hawks, and any aircraft with lifting capacity, he noted. “These are aircraft that have to land and take-off ... in all environments,” he said. “This is where it's most likely to be used initially ... and hopefully all aircraft will be outfitted with this technology eventually.” https://www.nationaldefensemagazine.org/articles/2020/8/14/new-tool-developed-to-improve-pilot-visibility
