  Japan suspends Aegis Ashore deployment, pointing to cost and technical issues

  By: Mike Yeo MELBOURNE, Australia — Japan has abruptly suspended the planned deployment of the Aegis Ashore ballistic missile defense system, which will drastically alter the U.S. ally's plans for defending itself against such threats. Defense Minister Taro Kono cited cost and technical issues as the reasons for the suspension of Japan's plans to deploy two Aegis Ashore systems at Japan Ground Self-Defense Force, or JGSDF bases at Akita Prefecture in the north of Japan's main island of Honshu and at Yamaguchi Prefecture in the south. He explained during today's announcement that that the main technical issue was the need to ensure that the rocket boosters of the interceptor missiles, which are used to accelerate the missile to supersonic speeds following their launch, will fall on its designated areas following separation from the missile. Attempts to modify the software on the SM-3 Block IIA missiles to ensure correct booster separation so as to not put civilian lives and infrastructure at risk have not been successful so far, with modifications to the missile hardware likely to be needed, the minister said. Kono added that Japan has already spent the equivalent of $1.02 billion on the development of the SM-3 Block IIA so far, which is being developed jointly by Japan and the United States. The missiles can also be fired from the Aegis equipped ships of both countries to intercept short- and intermediate-range ballistic missiles. Japan's Aegis Ashore deployment plans have been controversial, with the defense ministry facing strong opposition from local governments and residents at both sites, citing concerns about the radiation from the system's Lockheed Martin Long Range Discrimination Radar. The news of the suspension comes a little over a month after local media reported that the ministry will cancel the planned Aegis Ashore deployment at Akita and choose another site. However, this was swiftly denied by Japan Chief Cabinet Secretary Yoshihide Suga, who said at the time no decision had been made. In announcing the suspension of the Aegis Ashore deployment, defense minister Kono said that Japan will continue to rely on its Aegis-equipped destroyers to provide ballistic missile defense against North Korea's missiles in the meantime. Japan operates seven such destroyers and is building another, although the Aegis Ashore radars are more advanced than that used on the ships. The land-based systems also reduce the demands placed on the ships and their crews by the missile defense mission. The latest developments come as Japan announces completion of the deployment of an upgraded Patriot Missile Segment Enhancement, or MSE, interceptors at four different locations throughout the country earlier this month. The announcement was made during a media briefing by Gen. Yoshinari Marumo, chief of the Air Staff of the Japan Air Self-Defense Force, or JASDF, last Friday. The missile batteries, which can be used against aircraft or short-range ballistic missiles, are located at JASDF bases at Narashino, Hamamatsu, Ashiya, and Tsuiki. https://www.defensenews.com/global/asia-pacific/2020/06/15/japan-suspends-aegis-ashore-deployment-pointing-to-cost-and-technical-issues/

  Equinor extends CHC Helicopter contracts in Norway

  Recently, Equinor confirmed extensions for both its Tampen/Oseberg and Heidrun contracts with CHC for one year, effective from September 2020 to August 2021. This is for three Sikorsky S-92 search and rescue aircraft and three super puma A332L/L1. The aircraft are located at the Johan Sverdrup, Oseberg, Statfjord B and Heidrun rigs, and cover the area expanding from the Northern North Sea into the Norwegian Sea. The contracts offer the opportunity for further extensions. “We are delighted that we continue to enjoy Equinor's confidence in our ability to not only execute their service safely but also with outstanding efficiency and levels of customer service,” said Per Andre Rykhus, general operations manager, CHC Helikopter Services Norway. “We will continue to evolve our services and embrace the latest technology to best meet customer needs, building on our decades of experience in Norwegian oil and gas activity.” https://www.skiesmag.com/press-releases/equinor-extends-chc-helicopter-contracts-in-norway/

  Alaska-based long-range ballistic missile defense radar fielding delayed by a year

  By: Jen Judson WASHINGTON — The fielding of a U.S. Air Force radar to detect ballistic missile threats, currently being installed at Clear Air Force Station, Alaska, is delayed by roughly a year, according to a recent Government Accountability Office report. Information provided by the Missile Defense Agency in June to the GAO indicated all construction and integration activities for the Long Range Discrimination Radar had stopped in March due to the coronavirus pandemic. While initial fielding was planned for fiscal 2021 and transfer to the Air Force was planned for fiscal 2022, the service is now expected to take ownership of the operational radar in late fiscal 2023. “We did have some fallback in developing and delivery of systems because it requires people to be in close, confined spaces and sitting at computer terminals working through really tough problems like the development of an algorithm,” MDA Director Vice Adm. Jon Hill said at the virtually held Space and Missile Defense Symposium on Aug. 4. MDA shut down radar installation efforts due to the COVID-19 pandemic, entering a “caretaker status,” Hill said. “That requires additional work. I mean, you've got a radar that is being built in a tough environment like Alaska — you can't just stop. You have to go in and make sure the radar arrays are protected,” he added. The LRDR is an S-band radar that will not only be able to track incoming missiles but also discriminate the warhead-carrying vehicle from decoys and other nonlethal objects for the Ground-Based Midcourse Defense System, which is designed to protect the continental U.S. from possible intercontinental ballistic missile threats from North Korea and Iran. Lockheed Martin is LRDR's manufacturer. The program, according to the GAO report, wrapped up its system prototype assessment in an operational environment in FY19, which showed the hardware and software was mature ahead of full-rate manufacturing. That assessment was delayed from FY18, the report noted, after testing took longer due to “required antenna reconfigurations and software fixes to complete.” The fixes resulted in a cost overrun of $25 million and caused a delay in completing a developmental step associated with satellite tracking expected in FY18, according to the report. “While construction was ongoing in [FY19], the program was monitoring risks that could threaten the upcoming transfer of LRDR custody and ownership to the government,” the report stateed. “Specifically the program was focusing on manufacturing of the Array Panels, Sub Array Assembly Suite modules, and Auxiliary Power Group cabinets, as well as ensuring integration on site.” Those issues “depleted schedule margin on the path towards the transfer,” which was scheduled for the fourth quarter of FY20, according to the GAO, and the transfer of LRDR custody to the government was pushed back to the first quarter of FY21 due to radar component production issues. “The good news is construction is back up and running,” Hill said, “and we are delivering those arrays that are going into low-power and high-power testing later this year, so we are pretty excited about that.” According to the GAO, the current test plan for LRDR has just one flight test scheduled in the third quarter of FY21, after two ground tests. The report does not clarify if the pandemic has caused a delay in these tests. The GAO indicated concern about conducting two ground tests before the program's only flight test, as it “increases the likelihood that the models will not be accredited when testing is complete.” As a result, “the performance analysis and the majority of the model validation and accreditation will have to be made concurrently, just prior to the LRDR Technical Capability Declaration,” scheduled for the third quarter of FY21, the report stated. “This increases the risk of discovering issues late in development, which could result in performance reductions or delivery delays.” https://www.defensenews.com/digital-show-dailies/smd/2020/08/07/alaska-based-long-range-ballistic-missile-defense-radar-fielding-delayed-by-a-year/
