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.”

Fluor nets $1.07B for work on advanced naval nuclear propulsion
ByEd Adamczyk Oct. 1 (UPI) -- Fluor Marine Propulsion LLC received a $1.07 billion contract to continue its work at the Naval Nuclear Laboratory, the Defense Department announced. The contract covers work on naval nuclear propulsion technology, including the research, design, construction, testing, operation, maintenance and ultimate disposition to support safe and reliable operation of the country's submarine and aircraft carrier fleets. The Laboratory is a joint U.S. Navy-U.S. Department of Energy program and is operated by Fluor, with four facilities in three states. The lab is dedicated solely to support the United States Naval Nuclear Propulsion Program. The lab employs over 7,500 engineers, scientists, technicians and support personnel, all of whom will continue in their current roles and pay levels, with no reduction in force, the Pentagon said in the contract announcement. The contract calls for management and operation of facilities in Pittsburgh; Schenectady, N.Y., and Idaho Falls, Idaho. https://www.upi.com/Defense-News/2019/10/01/Fluor-nets-107B-for-work-on-advanced-naval-nuclear-propulsion

Key piece of F-35 logistics system unusable by US Air Force students, instructor pilots
By: Valerie Insinna EGLIN AIR FORCE BASE, Fla. — The F-35 fighter jet's logistics backbone has proven so clunky and burdensome to work with that the U.S. Air Force's instructor pilots, as well as students learning to fly the aircraft, have stopped using a key piece of the system, Defense News has learned. The Autonomic Logistics Information System, built by F-35 manufacturer Lockheed Martin, was supposed to consolidate training, maintenance and supply chain management functions into a single entity, making it easier for users to input data and oversee the jet's health and history throughout its life span. ALIS has been a disappointment to maintainers in the field, with updates coming behind schedule and many workarounds needed so it functions as designed. But the Air Force's F-35A instructor and student pilots at Eglin Air Force Base, Florida, and Luke Air Force Base, Arizona, were so disappointed with the performance of ALIS' training system that they bailed entirely, confirmed Col. Paul Moga, commander of Eglin's 33rd Fighter Wing. “The functionality in ALIS with regards to TMS — the training management system — was such a source of frustration and a time waste to the instructor pilots and the simulator instructors and the academic instructors that we at [Air Education and Training Command] in coordination with us [at Eglin] and Luke made a call almost a year ago to stop using the program,” Moga said during a Feb. 26 interview. Moga said the command's F-35 training squadrons are “not going to start using TMS again until it works.” So in the meantime, F-35A training squadrons have adopted a legacy system, Northrop Grumman's Global Training Integrated Management System. GTIMS is used by the Air Force, Army and Navy across a number of aircraft inventories to manage training schedules and cut the man-hours and costs associated with doing that work, according to a Northrop fact sheet. At this point, GTIMS provides a more agile, efficient user experience than ALIS' training management system, Moga said. But it doesn't sync with ALIS, so pilots and instructors must do “double data entry” so that each system has a record of flight records, currencies and qualifications.
