  CH-53E Heavy Lift Helicopter Reaches One Million Flight Hours

  Aircraft First Entered Service With The USMC In 1981 The CH-53E Super Stallion helicopter reached a major milestone this year by logging more than one million flight hours since it first entered service with the Marine Corps in 1981. The CH-53E is a versatile machine used for amphibious assault and long-range insertion, delivering troops, vehicles and supplies. This rapid resupply vehicle is still one of the most used aircraft in the United States military air arsenal. “The CH-53E has seen more work than was ever anticipated it would see,” said Major Matthew Baumann, H-53 In-Service, Naval Air Systems Command Heavy Lift Helicopter program office (PMA-261) co-lead. Currently, there are 142 CH-53E Super Stallions in service. Though out of production, the CH-53E is in the middle of a “RESET” – a rolling period of rebuilding, upgrading and increasing safety, reliability and capabilities to lengthen its service life through 2032. According to Baumann, the first 25 helicopters have completed their RESET process, “allowing the squadron commanders to plan for training, operations and maintenance with renewed confidence,” he said. Resetting of the CH-53E fleet is an important segue from the current platform to the new CH-53K King Stallion, which will be its heavy-lift replacement. “The CH-53K is the most powerful helicopter ever built by the United States military,” said Colonel Perrin, PMA-261 program manager. “It will be safer, faster and more capable than any previous heavy lift helicopter in the battlespace.” Its development is currently in the testing and capability requirements phase, with a goal of bringing the CH-53K to fleet Marines by 2024. “It's a game-changer,” said Perrin. “We can't wait to have the K available for fleet use. But for now we've got a capable, reliable and safe helicopter doing heavy-lift for our Marines.” http://www.aero-news.net/index.cfm?do=main.textpost&id=8e63f37f-9874-4fb9-acf1-72e67d6a9cbd

  New Sonar Sees Underwater From The Air, Promising To Transform Anti-Submarine Warfare

  Researchers at Stanford University have developed a new type of sonar to overcome the previously insurmountable problem of seeing underwater from the air. Sound does not travel easily between air and water: there is a 65-decibel loss, which means roughly a million-fold decrease in intensity, making it makes it virtually impossible to pick up sound reflections from the air. The new technology can map the seabed and potentially detect mines, submarines and other underwater targets from aircraft. Currently, the only ways of using sonar from aircraft are sonar buoys (sonobuoys) dropped into the water, or dipping sonar lowered to the sea surface from a hovering helicopter. The helicopter cannot move while using dipping sonar, so it has to check one spot, raising the sonar, fly somewhere else, lowering the sonar again, and so on. By contrast, the new Photoacoustic Airborne Sonar System or PASS, developed at Stanford with funding from the U.S. Navy, will work from a moving aircraft. “Our vision of the proposed technology is to capture images continuously as the airborne vehicle flies over the water,” Stanford researcher Aidan Fitzpatrick told Forbes. “Similar to how synthetic aperture radar systems or in-water synthetic aperture sonar systems work today.” https://www.forbes.com/sites/davidhambling/2021/02/04/new-sonar-sees-underwater-from-aircraft/
