    New National Guard medical helicopter unit set to deploy

    WINDSOR LOCKS, Conn. (AP) — The Connecticut National Guard's newest unit, which has spent the past two years training with new, specialized helicopters, will deploy soon to provide care and transport to the sick and wounded in support of military operations in southwest Asia. "To receive your first medical evacuation aircraft in 2016 and be fully prepared for a deployment less than two years later is a testament to the hard work and dedication of those in our aviation community," Maj. Gen. Thaddeus J.Martin, adjutant general and commander of the Connecticut National Guard, said in a statement ahead of a sendoff ceremony last month for the aerial medical evacuation unit, officially known as Detachment 2, Charlie Company, 3rd Battalion, 126th Aviation Regiment. The detachment, based in Windsor Locks and commanded by 1st Lt. Matthew Barringer of South Glastonbury, doesn't officially deploy until later this month. It represents a new capability for the National Guard. It received the first of three Blackhawk helicopters specifically outfitted for medical evacuation in the spring of 2016, even before becoming a fully operational unit in the fall of 2016. Thirty members of the detachment are deploying and will spend about a year providing aeromedical evacuation, en-route critical care and medical support while transporting patients. Five of the members deploying are women. The unit will join the 70 guardsmen from Connecticut already deployed in support of operations around the world. While deployed, the unit will be on 24-hour standby, and operate in shifts. A crew of four — two pilots, a crew chief, and a flight paramedic — can transport up to six patients at a time on one of the Sikorsky-built HH-60M Blackhawk helicopters. The helicopters have been specially outfitted for aerial medical evacuation and will be stocked with medical supplies like ventilators and IVs. The crew also has the capability to do procedures on board such as put in a chest tube. "We're almost a flying hospital," said Chief Warrant Officer Jonathan Behuniak, 28, of Unionville. From the time a call comes in, they have less than 15 minutes to grab supplies, get to the aircraft and take off to aid a patient, who could be a member of the U.S. military or coalition forces, contractors, and even military working dogs, Behuniak said. Through training, they've been able to get that number down to nine minutes. "There are a lot of computers that need to start working, so as fast as the aircraft will let us take off, we can take off," Behuniak said. The benefit of a medevac unit, he added, is the ability to get a critically wounded patient to a hospital within so the so-called "golden hour," which greatly increases a patient's chance of survival. A 2015 study involving the Army, Texas A&M University and the University of Texas Medical School at Houston found that getting wounded troops to hospitals in less than an hour, along with improved care on the battlefield and in medical helicopters, saved hundreds of lives. "There's a wide spectrum of care an injured person can receive on this aircraft," said Sgt. Ryan Will, 28, Manchester, a flight paramedic. "It's very comprehensive care as well." Flight paramedics like Will and Staff Sgt. Trevor O'Neill, 27, of Greenwich, have gone through extensive training and are nationally registered paramedics. Both are also civilian paramedics. Members of the unit underwent a range of training to prepare them for the conditions they'll encounter overseas. They trained at a facility in Rhode Island that can simulate desert conditions. Anticipating mountain peaks of 13,800 feet, some pilots went to Colorado for training to get an understanding of how air density affects a helicopter's rotor system and the ability to fly. Last week, they trained with members of Air National Guard's 103rd Airlift Wing, practicing loading and unloading patients onto the helicopters, and simulating different missions where the two units would cross paths. "There are a lot of gravity and effects that are placed on the patient that there aren't normally on the ground, whether that be from high maneuver turns or simply just taking off and landing. Things like vibrations can really make a patient uncomfortable and these are things they have to know when they're giving us patients," said O'Neill, one of the flight paramedics. There was strong interest in joining the unit, which represents a new capability for the Connecticut National Guard. Second Lt. Brett Boissonneault, 25, of East Hampton, was handpicked out of flight school to be part of the unit. "It's a great opportunity to be part of an important mission where we're saving people every day, helping people every day," he said. https://www.sfchronicle.com/news/article/New-National-Guard-medical-helicopter-unit-set-to-12984985.php

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

    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

    Army Eyeing Navy's High-Powered Laser to Fight Enemy Drone Swarms

    By Matthew Cox Army modernization officials are getting help from the Navy to make the service's High Energy Laser program more than twice as powerful for fending off aerial attacks from swarms of enemy drones. Currently, the Army's High Energy Laser Tactical Vehicle Demonstrator (HEL TVD) features a 100-kilowatt laser designed to fit on Family of Medium Tactical Vehicle (FMTV) trucks. The service plans to conduct a demonstrationof the system's target acquisition, tracking and other capabilities against a range of targets in 2022. Meanwhile, the Army's Rapid Capabilities Office plans to take advantage of the Navy's 250-kilowatt laser program, a system that could be adapted to fit on the FMTV platform, Army Lt. Gen. Paul Ostrowski told an audience Tuesday at an Association of the United States Army Institute of Land Warfare breakfast. "The intent is to work with the Navy, and we are doing that right now, in order to increase the power of that laser system from beyond 100-kilowatt up to maybe the 250-kilowatt mark," said Ostrowski, the military deputy to the assistant secretary of the Army for acquisition, logistics and technology. The Army's 100-kilowatt HEL TVD is being designed to provide air and missile support to forward operating bases and airfields, Ostrowski said. The service also plans to field a platoon of four 50-kilowatt lasers, known as Maneuver Short Range Air Defense (M-SHORAD) that will be mounted on a Stryker combat vehicle in fiscal 2022. The advantage of the laser is having an "unlimited magazine" for unmanned aerial systems, as well as rockets, artillery and mortars, instead of "shooting $100,000 missiles at $7,000" unmanned aerial systems, Ostrowski said, adding that the Army hopes to expand the potential use of lasers on the battlefield beyond air defense. "We want to be able to put that capability on our tanks to potentially get after targets that our combat vehicles can go after, so this is just the beginning ... of where we see lasers going in the future," he said. One of the challenges of working with lasers, Ostrowski said, is controlling the heat buildup generated by the power source. "It's not just the ability to create the energy to fire the laser, but it's also to dissipate the heat," he said. It's still uncertain whether the Navy's 250-kilowatt laser program will work for the Army, but "we are not going to ignore" its potential for dealing with more complex enemy air attacks, Ostrowski said. "The power piece is extremely important. If you don't have the power, you don't have that unlimited magazine, and that unlimited magazine makes a difference in a swarm environment where you have multiple targets and you have to be able to ... recharge quickly and be able to shoot them all down," he said. https://www.military.com/daily-news/2019/07/16/army-eyeing-navys-high-powered-laser-fight-enemy-drone-swarms.html
