  Sikorsky nabs $91.2M contract to support U.S. Army Black Hawks

  By Ed Adamczyk June 26 (UPI) -- Sikorsky Aircraft Co. was awarded a $91.2 million contract for work on all versions of the U.S. Army's H-60 Black Hawk helicopter, the Defense Department announced. It was the only bidder on the hybrid cost-plus-fixed-fee and firm-fixed price contract with the Army, which was announced on Tuesday, and only referred to engineering and other support services for the helicopters. The Black Hawk UH/HH-60 is regarded as the Army's utility tactical transport helicopter. The rotorcraft provides combat air assault, general support, aeromedical evacuation, command and control, and special operations support to combat, stability and support operations. The Army bills it's specialty asenhancing the branch's overall mobility due to dramatic improvement in troop and cargo lift capacity. The helicopter, introduced in 1974 and in U.S. military service since 1979, is also used by the military forces of Japan, Colombia and South Korea. Over 4,000 have been built. Variants, including the UH-60L and UH-60M, have been developed for electronic warfare and special operations. Work locations and funding will be determined with each order, the Army said, with the contract estimated to run through June 27, 2024. https://www.upi.com/Defense-News/2019/06/26/Sikorsky-nabs-912M-contract-to-support-US-Army-Black-Hawks/1611561562477/

  NAVAIR looking for emerging cyber research and development

  Mark Pomerleau CORRECTION: A previous version of this story misidentified the organization soliciting white papers as the Naval Information Warfare Systems Command. WASHINGTON — The Navy is searching for solutions from industry that can fill needed gaps in cyber warfare capabilities to secure weapon systems and exploit cyberspace. The Naval Air Systems Command Cyber Warfare Detachment is looking for white papers for research and development efforts on resilient cyber warfare capabilities, according to a Feb. 11 posting to a government contracting website. The proposals should offer advancements or improvements to fill gaps, the notice stated, listing eight buckets of technological interests: Size-, weight- and power-sensitive cyber resiliency for real-time operating systems and aviation warfare environment Access point identification, prioritization and defense Cyber-electronic warfare convergent capabilities Full acquisition cycle cybersecurity measures Cyber test, inspection and incident response concepts Cyber warning system techniques Cyber fault, risk and threat assessment methodologies Resilient network concepts NAVAIR provided a more in-depth list of 36 specific areas, including full-spectrum cyber response and enablement capabilities for multiple weapon system kill chains, sacrificial infrastructure and reactive cyber “armor,” deceptive/misinformation software and hardware capabilities, threat attribution, identification and geolocation, software defined radio protections and capabilities networking, tools for weapon system cyber protection teams for incident response and inspection, and suppression and discovery of malware command and control mechanisms to include triggering, reconnaissance and logic bombs. The command will accept responses until Feb. 10, 2022, and review them quarterly. The next phase of the program will be by invitation. https://www.c4isrnet.com/cyber/2021/02/11/navwar-looking-for-emerging-cyber-research-and-development/

  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
