    South Korean study finds Chinook upgrade more expensive than buying new helos

    Brian Kim SEOUL — Research on the long-awaited upgrade of Chinook helicopters flown by the South Korean military shows it would be cheaper to buy new aircraft, according to a local lawmaker. Rep. Min Hong-chul of the ruling Democratic Party revealed the result of the latest preliminary research on the Chinook upgrade during a parliamentary audit of the Defense Acquisition Program Administration on Oct. 20. The lawmaker, who sits on the National Assembly's Defense Committee, said the research concluded in September that the cost of upgrading 17 of the 43 CH-47D Chinook helicopters would be about 1.35 trillion won ($1.2 billion), which is higher than the estimated cost of 1.22 trillion won for buying new ones. The upgrade cost is partly driven by the fact that Chinook manufacturer Boeing no longer produces parts for older variants, like those owned by South Korea, so specially ordered parts could prove expensive, Min said, citing the research conducted by the Defense Agency for Technology and Quality, which is affiliated with DAPA. Furthermore, some Korean military task equipment such as the Korean Variable Message Format data link cannot be installed on the upgraded helos due to incompatibility, the research suggested. “A series of reverses and delays on decision-making have foiled key arms acquisition projects, including the Chinook upgrade,” Min said, expressing concern about an operational gap in military transport trainings and missions. South Korea operates about 50 Chinooks, with some of them in service for up to 50 years. With some parts of the older Chinook no longer being produced, the South Korean fleet's operational rate has suffered, according to the lawmaker. For instance, the Air Force's Chinook utilization rate from the first half of the year was around 40 percent. DAPA is expected to hold a meeting soon to decide whether to buy new heavy-lift helicopters rather than upgrade the existing fleet. But industry sources expect buying new helos would take more time and end up costing more, depending on the variant. “To get Block I CH-47F Chinook cargo helicopters, which have been on the shopping list of the South Korean Army, the letter of offer and acceptance should be issued by July next year at the latest, but it would be very difficult to finalize the decision-making procedures within the timeline,” said Ahn Seung-beom, a military analyst and writer with Defense Times Korea. “[If it doesn't] buy Block I, South Korea has an option to get Block II, which is to be produced for the U.S. Army first, and then it could take more time and costs to get the up-to-date, heavy-lift helicopters.” A source at Boeing told Defense News that both cost and an export license stand in the way of South Korea's CH-47F Block II purchase. “The development of the CH-47F Block II is still underway, so the price cannot be expected at this moment,” the source explained on condition of anonymity. “The U.S. Army has yet to place an order for the new cargo helicopters, so it's unclear how many aircraft would be produced.” It's also unclear if a foreign sale will receive approval, the source added. “The U.S. government strictly controls arms technology, so getting an export license for key weapons systems is a hurdle.” https://www.defensenews.com/global/asia-pacific/2020/10/27/south-korean-study-finds-chinook-upgrade-more-expensive-than-buying-new-helos/

    Chinese threats means the Pentagon needs new C4ISR systems

    By: Chiara Vercellone For the United States to meet the goals laid out in the National Defense Strategy, especially in Asia, and to realize President Donald Trump's vision of an open Indo-Pacific, the Department of Defense's battlefield technology must undergo significant changes, according to a Center for a New American Security report released Jan. 28. The report, an independent assessment mandated by Congress in the 2019 National Defense Authorization Act, proposed the revamping of C4ISR systems as they remain “brittle in the face of Chinese cyberattacks, electronic warfare and long-range strikes.” The Pentagon's C4ISR capabilities have fallen behind technologically, as they were developed “in an era when competitors or adversaries could not attack U.S. assets in space or at long ranges,” the report found. At the same time, a 2019 Department of Defense's report on China's military and security developments found that country has prioritized military capabilities with disruptive potential, including hypersonic weapons, counterspace capabilities, artificial intelligence and C4ISR advanced robotics. Thus far, the Department of Defense has been able to develop countermeasures against China's abilities, said Chris Dougherty, a senior fellow at CNAS and one of the authors of the report. “As the threat continues to get more sophisticated, these [countermeasures] will likely lose their effectiveness,” Dougherty said. “This necessitates building a new architecture that is designed around resiliency, kill webs, and graceful degradation.” While under attack, U.S. systems sometimes fail to have any connectivity and have sporadic dial-up speeds. Instead, they should still have some level of communication even while the attack is going on, even if this means at lower bandwidths. To strengthen its systems, the report recommended, the U.S. military should develop space capabilities resistant to kinetic attacks, synthetic training environments for U.S. forces to practice C4ISR operations, systems that can transmit data via multiple pathways and surveillance systems that can avoid being detected. A recent project by RAND found that, while the Department of Defense maintains an advantage in airspace penetration capabilities, it remains vulnerable to air base attacks and Chinese anti-surface warfare. An initial system with these developments could be in place in the next decade if the Department of Defense and armed services create a basic system and improve it over time, Dougherty said. “If, as we have done in the past, we wait around for a ‘perfect' set of requirements to develop an ‘objective' future system, we could see this take 15-20 years, at which point China will likely have far surpassed us in this competition,” he said. https://www.c4isrnet.com/newsletters/daily-brief/2020/01/29/chinese-threats-means-the-pentagon-needs-new-c4isr-systems/
