  BAE successfully tests solar-powered high-altitude plane

  ByEd Adamczyk Feb. 17 (UPI) -- A solar-powered unmanned aircraft with a wingspan of 114 feet completed its maiden high-altitude flight in the stratosphere, maker BAE Systems said on Monday. The plane, called PHASA-35, which stands for Persistent High altitude Solar Aircraft and its wingspan measured in meters, is meant to fly about 32 miles above the earth in the space, in the upper atmosphere between conventional aircraft and satellites. The aircraft's solar-powered batteries could allow it to stay aloft for over a year at a time, providing a stable platform for monitoring, surveillance, communications and security applications. It can also offer military and commercial customers with capabilities not available from existing air and space platforms, and could be used in communications networks disaster relief and border protection at a fraction of the cost of satellites, BAE said in a statement. The plane, which went from proof of capability to testing in only 20 months, is underwritten by Britain's Science and Technology Laboratory and Australia's Defense Science and Technology Group, and built by BAE Systems and its subsidiary, Prismatic Ltd. Its flight trials were successfully completed at the Royal Australian Air Force Woomera Test Range in South Australia. "To go from design to flight in less than two years shows that we can rise to the challenge the U.K. government has set industry to deliver a Future Combat Air System within the next decade," said Ian Muldowney, engineering director at BAE Systems. Additional test are scheduled for later this year, with plans to enter initial operations with customers within 12 months. Airbus is among companies competing in the high-altitude, long-endurance category of planes, and in 2019 completed a 26-day test flight of its solar-powered Zephyr S "High Attitude Pseudo-Satellite." https://www.upi.com/Defense-News/2020/02/17/BAE-successfully-tests-solar-powered-high-altitude-plane

  Watchdog warns Pentagon to fix F-35 tech problems before full-rate production starts

  By: Valerie Insinna WASHINGTON — The F-35 fighter jet is finally cruising toward the end of its development phase, but a congressional watchdog is warning the Defense Department not to move to full-rate production until it's certain it's resolved all critical technical issues. The F-35 Joint Program Office intends to make a decision in October 2019 on whether to move to full-rate production, but had planned to defer certain critical technical deficiencies until after that time, the Government Accountability Office stated in a June 5 report. That could make the program more expensive overall. “In its rush to cross the finish line, the program has made some decisions that are likely to affect aircraft performance and reliability and maintainability for years to come. Specifically, the program office plans to resolve a number of critical deficiencies after full-rate production,” it wrote. “Resolving these deficiencies outside of the developmental program may contribute to additional concurrency costs.” The GAO advised the F-35 JPO to resolve all critical deficiencies before full-rate production — a recommendation with which the JPO concurs and says it will pursue. However, it's important to understand what “resolve” means in this case. “The Department of Defense expects the F-35 Program to resolve all critical deficiencies prior to entering Initial Operational Test and Evaluation (IOT&E), with either a fix, a Service Operational Test Agency approved workaround or a formal acceptance of the deficiency,” the JPO said in a statement. “The full-rate production decision will include an assessment of SDD [development phase] and IOT&E DRs [deficiency reports], as well as follow-on improvement DRs deferred for post-SDD action.” Translation: While the JPO will take steps to address all critical deficiencies, there are some that may require future work in order to be completely fixed. GAO noted that it is common practice for Defense Department acquisition programs to require that problems are “resolved” and not “fixed” because it “affords the department with more flexibility to develop alternative solutions rather than technical fixes.” In a statement, Greg Ulmer, Lockheed Martin's vice president of the F-35 program, said the company was working with the JPO to prioritize and correct issues. The F-35's next stage The GAO report was also critical about the JPO's new plan for Block 4 follow-on modernization, telling its congressional audience that it should consider holding back funding for that phase of the program until the JPO provides full details including an independent cost estimate, final acquisition strategy and test plan. Last year, Vice. Adm. Mat Winter, the F-35's program executive, announced that the JPO would pursue a path of rapid, agile software modernization during Block 4 called continuous capability development and delivery, or C2D2. The thrust behind C2D2 is for the government to constantly be developing, testing and delivering new capabilities as they become available, instead of as part of a traditional batch of upgrades every couple years. Currently, the cost of the new plan is unknown. The Department of Defense plans to update its acquisition strategy in time for a Defense Acquisition Board meeting this month, when it will decide when to start the competition for Block 4 development.

Sign up for our Military Space Report Get the latest news about space and strategic systems Subscribe However, a full business case won't be finalized until March 2019 — despite the fact that the Pentagon has asked for $278 million in fiscal 2019 for Block 4 development. “As a result, DOD requested funding for modernization over a year before the program has a business case for Block 4,” the report stated. “This means that the program is asking Congress to authorize and appropriate funds for Block 4 without insight into its complete cost, schedule, and technical baselines. Furthermore, once Congress appropriates these funds, DOD would be able to award a contract, beginning a long-term commitment to Block 4, the costs of which are not fully understood.” However, the GAO also acknowledged that there are some elements of that plan that could end up being a boon to the DoD. For one, it plans to use “government-owned open systems architecture and acquire data rights” for Block 4 development, which could increase competition throughout the F-35's life cycle and make it easier and cheaper to upgrade the platform. The C2D2 strategy may also “potentially shorten time frames for delivering capabilities over a traditional acquisition approach,” the agency said in the report. Most of the noted flaws in the C2D2 plan revolve around oversight — specifically the DoD's decision to keep Block 4 underneath the F-35 program instead of making it a separate acquisition program. “According to DOD's January 2018 report, however, each capability will be baselined separately in the program's future Block 4 annual reports to Congress,” the GAO noted. “We will review these future reports to Congress to determine what level of insight they provide into the program's cost, schedule, and performance goals.” https://www.defensenews.com/air/2018/06/05/watchdog-group-to-pentagon-fix-f-35-tech-problems-before-full-rate-production-starts/

  US Warship Fries Drone With Powerful New Laser

  In a first, the USS Portland took down a target drone with a new solid state laser this week, the first step in the Navy's quest to get the powerful weapon on more ships in the future. By PAUL MCLEARY WASHINGTON: In a first, the USS Portland took down a target drone with a new solid state laser this week, the first step in the Navy's quest to get the powerful weapon on more ships in the future. The shot from the San Antonio-class landing platform ship tested out what's known as the Technology Maturation Laser Weapon System Demonstrator, or LWSD, which has been aboard the ship for several months. The May 16 test, announced by the Pacific Fleet today, is the first public acknowledgement of the system being put to use. The Northrop Grumman-made LWSD is a high-energy laser weapon initially developed by the Office of Naval Research, and its operational employment marks “the first system-level implementation of a high-energy class solid-state laser,” according to a Pacific Fleet release. The test comes as the US, in bits and pieces, ramps up operations in the Pacific as a counterweight to China — moves which include new, ambitious B-1 bomber flights close to Russian and Chinese territory. Just this week, the USS Ronald Reagan and Theodore Roosevelt carriers went back to sea from bases in Japan and Guam, respectively, while the USS Nimitz is getting its air wing up to speed off the coast of Washington state. And earlier this month, two Navy ships sailed into the middle of an ongoing dispute between China and a neighbor in the South China Sea — steaming near a shadowing Chinese warship in Washington's latest effort to show presence in an increasingly contested waterway. The Littoral Combat Ship USS Montgomery and supply ship USNS Cesar Chavez sailed close to a Malaysian drillship, the West Capella, warning off Chinese warships who spent weeks harassing the commercial vessel in international waters illegally claimed by Beijing. Since the passthrough, both the Chinese and Malasyian ships have moved away from one another. Late last month, the destroyer USS Barry cruised near the Paracel Islands, claimed by China, followed a day later by the cruiser USS Bunker Hill sailing near the Spratlys conducting freedom-of-navigation operations. On April 30, a day after Bunker Hill's transit, two B-1 bombers flew over the South China Sea. These transits came just days after the USS America amphibious ship packed with Marine Corps F-35s passed through the South China Sea while conducting flight operations. The laser test was much quieter, but no less significant in the long run. “By conducting advanced at sea tests against UAVs and small crafts, we will gain valuable information on the capabilities of the Solid State Laser Weapons System Demonstrator against potential threats,” said Capt. Karrey Sanders, commanding officer of Portland. The LWSD is thought to pack about 150kw worth of power, a step up from the smaller, 50kw laser that was tested on the USS Ponce starting in 2014. https://breakingdefense.com/2020/05/us-warship-fries-drone-with-powerful-new-laser/
