Stealthy UAS Unveiled For USAF Target, Loyal Wingman Needs
Steve Trimble
A small start-up company in California has unveiled a new proposal for a stealthy unmanned aircraft system (UAS) to offer the U.S. Air Force as a “fifth-generation” target drone or a low-cost attritable aircraft.
Tehachapi, California-based Sierra Technical Services, a company founded by previously retired Lockheed Martin Skunk Works engineers, unveiled the first photos of the completed Fifth Generation Aerial Target (5GAT) prototype after completing engine tests on the ground. A first flight of the 5GAT is scheduled in early 2020.
The name of the aircraft is derived from its origins as a prototype funded by the Defense Department's Director of Operational Test and Evaluation (DOT&E), says Roger Hayes, president and CEO of Sierra Technical Services.
Several years ago, DOT&E recognized an emerging gap for a new target drone that could fly as a surrogate for fifth-generation fighters emerging in Russia and China such as the Sukhoi Su-57 and AVIC Chengdu J-20. In 2017, DOT&E awarded Sierra Technical Services a $15.9 million contract to develop the 5GAT prototype, Hayes said.
The pace of assembly has been dictated by the availability of parts cannibalized from other military aircraft, such as the engines and metallic components from the Northrop T-38 trainer and F-5 fighter, as well as aileron actuators from the Boeing F/A-18, Hayes said. Sierra Technical Services supplemented its revenue as assembly continued by working on other programs, including supplying components for the Kratos XQ-58A Valkyrie.
As development continued, the Air Force started to develop interest in a fifth-generation target. The service has awarded Lockheed Martin a contract to develop the AIM-260 Joint Advanced Tactical Missile, which is being designed to counter the PL-15 missile fielded on China's J-20 fighter. The Air Force needs to test the AIM-260 and other missiles against a representative threat. Last May, the Air Force released a request for information for the Next Generation Aerial Target, which included a version that can replicate fifth-generation fighter attributes, such as a stealthy airframe with canted tails and serpentine inlet ducts.
The Air Force also is developing a concept to pair manned fighters such as the F-22 and F-35 with an unmanned partner, known sometimes as a Loyal Wingman. The Air Force Research Laboratory (AFRL) funded Kratos' XQ-58A, which completed a first flight in March.
AFRL also plans to demonstrate a UAS controlled by a “software brain” using artificial intelligence. This Skyborg program is sometimes considered a follow-on for the XQ-58A program, but Hayes said Sierra Technical Services could offer the 5GAT for the Skyborg contract.

Failure of Two Ships to Participate in RIMPAC Highlight Amphibious Readiness Gap
By: Sam LaGrone and Megan Eckstein THE PENTAGON — The two U.S. amphibious warships that were planned to be central to the Rim of the Pacific 2018 exercises were unable to fully participate in the event due to mechanical failures that highlight continued readiness problems with the Navy's amphibious fleet. The amphibious assault ship USS Bonhomme Richard (LHD-6) was set to lead the amphibious portion of the Rim of the Pacific 2018 exercise, but it spent the second half of the exercise tied to a pier in Pearl Harbor. USS Boxer (LHD-4) was set to be a key platform in Southern California RIMPAC SOCAL but was sidelined before the exercise. In December, half of the Navy's 31 amphibious ships were in maintenance as a result of short-term spending bills and irregular funding, Vice Adm. Andrew Lewis, deputy chief of naval operations for operations, plans and strategy (OPNAV N3/N5), said at a House Armed Services readiness subcommittee hearing. Bonhomme Richard was set to be the command ship for the exercise's maritime component commander, Chilean Navy Commodore Pablo Niemann Figari. However, partway through the exercise the ship suffered a propulsion casualty and came back to port, USNI News understands. Niemann, his staff and the ship's company still participated in the exercise from the pier, USNI News understands. “USS Bonhomme Richard (LHD-6) is currently in port Pearl Harbor and is participating in RIMPAC 2018,” reads a U.S. 3rd Fleet statement to USNI News this week. Officials would not elaborate on why the ship was not underway. Full article: https://news.usni.org/2018/08/01/failure-two-ships-participate-rimpac-highlight-amphibious-readiness-gap

How the Navy can lean in to software superiority
Andrew C. Jarocki The Navy needs to take a "hard look” at its digital needs according to a senior Navy software official, especially in technology such as machine learning and artificial intelligence, or risk vital weapons systems failing on the future battlefield. Attendees of the Amazon Web Services Public Sector Summit in Washington June 21 heard warnings that obsolete and slow approaches are driving up costs of time and resources for the Navy's newest technologies that interact with one another in combat. "It's really a matter of making System A talk to System B,” said Richard Jack, a lead engineer and project director at the Space and Naval Warfare Systems Center Pacific. “A logistics system that needs to be able to interact with a weapons system.” Software superiority is an important part of the Navy's plan for a global competitive edge, from unmanned underwater vehicles to drones operated from ships. Unless the Navy wants to get an error message at a crucial combat moment, they will have to search outside their own technology labs for the solution to the interoperability challenge, Jack said. “The Navy can't do this alone, as 99 percent of the brain trust is in the cloud service providers and the industry,” Jack stated. He expressed the need to “take advantage” of lessons learned by cloud industry leaders on big data collection and interpreting results to make predictions . Jack suggested accelerating operations with increased cloud computing, creating shared infrastructure to make sure data centers are connected, eliminating duplicative investments across some programs, and further expanding AI and machine learning advancements. The software engineer expressed confidence that learning from cloud service providers will result in the Navy enhancing warfighting abilities, envisioning a cloud to allow instant data sharing “between a weapons system, an airframe, a UAV, and a logistics system” at the same time. Jack also praised cloud computing as important to the “compile to combat” program, in which the Navy is experimenting with ways to deploy new software capabilities to ships at sea in less than 24 hours. While the cloud can “be super fast and super efficient” for accessing large amounts of data anywhere, Jack also promised that it also allows the Navy to “really push the boundaries of machine learning,” even though “we are behind the curve” at the moment. Through “strategic partnerships” with the “Amazons, Googles and IBM Watsons of the world,” Jack promised the Navy could accomplish even more in the areas of AI and machine learning that will dominate warfighting in the era of the cloud. https://www.c4isrnet.com/it-networks/2018/06/25/how-the-navy-can-lean-in-to-software-superiority/
