  How Army IT modernization is reshaping this cadre of soldiers

  By: Mark Pomerleau The Army's efforts to modernize its tactical networks and information technology are expected to reshape its signal corps, according to service officials. One of the Army's efforts includes creating what is known as “expeditionary signal battalion-enhanced," or ESB-E. Expeditionary signal battalions support units that don't have organic communications capabilities. These groups could include military intelligence battalions, chemical battalions, engineering battalions or air defense artillery branches. However, the Army realized it took too long to get equipment to theater, and the units said the gear performed too slowly on the battlefield, Sgt. Maj. Wendle Marshall, the head of 50th ESB-E, told C4ISRNET during a September trip to Fort Bragg, North Carolina. In response, the service adopted a more expeditionary approach, hence the “enhanced.” The Army as a whole is working to be more expeditionary and mobile to stay ahead of potential future threats, which will require units to move rapidly. Mobility extends to the overall tactical network modernization effort, for which the ESB-E is part of the first iteration of development to the force in 2021. The 50th ESB-E is the experimental unit, and three of its companies each received different equipment to test. When the Army receives feedback from those units and makes a decision on fielding, it will retrofit the entire battalion with the same gear. In 2021, the Army plans to outfit three ESB-Es out of 24 total ESBs. The biggest difference between the enhanced version of these battalions? Advancements in technology allow them to be more mobile and use less equipment while proving more capable. Soldiers described to C4ISRNET the difference in equipment between two sister battalions in the same signal brigade — one being an enhanced battalion. Based on the current configuration of a company in a typical battalion, six vehicles are needed to establish communications for a battalion or brigade — three vehicles and three trailers totaling six drivers — and three to seven C-17 planes to transport the vehicles. The enhanced versions can deploy that same company in a single C-17 requiring just a four-seat Humvee and one trailer to house equipment and personal gear. “If we had to get somewhere fast, we would not be able to provide the combat power as effective or fast as the ESB-E would,” Lt. Col. Trey Matchin, commander of 67th Expeditionary Signal Battalion, a sister battalion of the 50th located at Fort Gordon, Georgia, told C4ISRNET. Marshall said the enhanced battalions also aren't constrained to just satellite communications. “This kit's allowing us to change force structure to meet the needs of the Army,” Col. Matthew Foulk, commander of 35th Signal Brigade, which includes the 50th and 67th, told C4ISRNET in August. Moreover, with less equipment, soldiers' loads are lighter, they are more multifunctional and they rely less on contractor support. “ESB-Es being fielded is going to come to an apex at the perfect time. Which is creating a more multifunctional soldier instead of ‘I only do SATCOM [satellite communications] or I only do baseband, I only do radios.' We're getting away from that,” Foulk said. Marshall demonstrated how the motor pool for the 50th is smaller and simplified compared to sister battalions. One prominent example is an operations cell in which soldiers work on their kits as opposed to contractors. This allows war fighters to become proficient on systems ahead of exercises. https://www.c4isrnet.com/show-reporter/ausa/2019/10/15/how-army-it-modernization-is-reshaping-this-cadre-of-soldiers

  Coulson’s CU-47 is ready for the fire fight

  Posted on May 22, 2020 by Howard Slutsken Leveraging its experience with fixed-wing air tankers, Coulson Aviation has unveiled its latest aerial firefighting conversion, based on the Boeing CH-47D Chinook heavy-lift helicopter. In early March, the first Coulson-Unical CU-47 was flown from the company's Port Alberni, B.C., base to the Aerial Firefighting North American 2020 conference in Sacramento, Calif. Featuring a 3,000 gallon roll-on/roll-off internal tank and an advanced Garmin avionics suite, up to 12 CH-47Ds will be converted into next-generation heli-tankers, in a partnership with Unical Aviation that was announced a year ago. “Unical provides us with the aircraft and a vast supply of parts,” explained Britt Coulson, president and COO, in an interview with Skies. “They bought the entire Canadian Forces CH-47 parts inventory and were the largest purchaser of CH-47Ds from the U.S. Army.” The twin-rotor Chinook is well known for its speed, size and payload. While the helicopter is often deployed on fire attack missions carrying a water bucket as an external load, Coulson wanted to give the CU-47 more flexibility and capability. The company's engineers had already developed a 4,000 gallon Retardant Aerial Delivery System RADS-XXL for its Lockheed C-130 Hercules tanker conversions, and that tank was shrunk to create a 3,000 gallon RADS-L for the CH-47D conversion. “It's the same overall design as the C-130. It shares most of the same hydraulic components, the same doors and the same design of a roll-in, roll-out tank,” said Coulson. Other CH-47 internal tank systems utilize the small hook well in the centre of the helicopter as the water and retardant delivery port, but according to Coulson, that has its limitations. “The other tank designs are plagued with flow rate issues, which means they don't pack enough punch to really get through [forest] canopies or drop in heavy timber – the hook well opening just isn't big enough. “The lower the flow rate you have out of your tank, the slower and lower you have to fly. The problem with a big helicopter like a Chinook is if you fly too slow and low, your downwash is going to negatively affect the ground fire conditions and your drop is going to be ineffective.” To increase and optimize the flow rate for the RADS-L, the belly of the CH-47D was modified by cutting the helicopter's lower skin and adding structure below the floor to accommodate the tank installation and a pair of drop doors, controlled by the pilots through a state-of-the-art touchscreen controller. From the same touch panel, the pilots also control the CU-47's newly-developed retractable snorkel system to refill the RADS-L tank from water sources close to a fire's location. Installed internally, the snorkel head sits flush with the belly when retracted, so that with no additional external drag, the helicopter can maintain its fast 140-knot cruise speed. In a hover, the snorkel takes just four seconds to deploy and six seconds to retract, and the pilots and flight engineer can monitor the system's operation via a high-definition belly-mounted camera feed, displayed on the touchscreen controller. “The snorkel system has exceeded our expectations and we're filling the entire tank in under two minutes,” said Coulson. With the advanced capabilities of the Garmin avionics, the relocation of the flight engineer's panel, and the new RADS-L tank, Coulson originally believed that the CU-47 could be crewed solely by two pilots, without a flight engineer. But recent operational experience led the company to rethink that strategy. “We realized that with a helicopter of this size, going into some of the smaller dip sites, to have an additional set of eyes looking out the side or back is valuable to the pilots. So we've de-modified the helicopter and gone back to a full-time flight engineer to provide that increased safety and situational awareness.” Like Coulson's C-130 conversions, the CU-47 can also be tasked with night-time firefighting missions, thanks to the Night Vision System (NVS) certification of the helicopter's avionics suite. Wearing NVS googles, the CU-47's crew work in tandem with a fire attack “Intel” helicopter's pilots. The Intel crew uses a thermal camera to evaluate the behaviour of a fire, and if a drop is required, they take a page from military ground-attack operations. Using a laser, the Intel crew designates the target for the tanker. “With a geo-referenced lock, the Intel helicopter can orbit, and the laser beam will stay on the same spot. It illuminates an area on the ground about the size of a car,” said Coulson. The first CU-47 will soon be joined by a second RADS-L equipped helicopter, two CU-47's with upgraded avionics that will fly “bucket” missions, and a fifth, tank-equipped CU-47 that will deploy as a spare. “All of our FAA testing [on RADS-L] has finished, we're just waiting for the final Supplemental Type Certificate signature,” said Coulson. “We're doing some minor cleanup to the helicopter to make sure that it's ready to go fight fires this summer.” Howard Slutsken's lifelong passion for aviation began when he was a kid, watching TCA Super Connies, Viscounts, and early jets at Montreal's Dorval Airport. He's a pilot who loves to fly gliders and pretty much anything else with wings. Howard is based in Vancouver, B.C. https://www.skiesmag.com/features/coulsons-cu-47-fire-fight
