  DARPA awards nine new contracts to foster drone swarm technology

  Nathan Strout The Defense Advanced Research Projects Agency has issued nine new contracts to companies developing drone swarm technologies, the agency announced April 13. Through the agency's Offensive Swarm-Enabled Tactics program, or OFFSET, it hopes to foster technology developments that will enable 250 small unmanned air or ground robots to work together in support of the war fighter. The program works in five main areas: swarm tactics, swarm autonomy, human-swarm teaming, virtual environment and physical test bed. The agency has hosted multiple swarm sprints to encourage rapid innovation in one or more of those areas. The nine awards mark the fifth such swarm sprint, with this one focused on swarm tactics and physical test beds in an urban environment. “The urban environment presents compelling challenges such as tall buildings, tight spaces, and limited sight lines,” Timothy Chung, the OFFSET program manager in DARPA's Tactical Technology Office, said in an agency news release. “Enhancing the Swarm Physical Testbeds that tackle those unique challenges is a desired goal of the OFFSET program.” Four of the participants will be tackling the swarm tactics portion of the sprint, where they will be asked to solve problems such as “disrupting the opposition's decision making, obfuscating swarm intent, updating maps of a dynamic environment, and maintaining the swarm's communications indoors.” The remaining five performers will work on the physical test bed thrust area, which includes reducing deployment times, utilizing new navigation sensors, incorporating fixed-wing aircraft into the swarm and enhancing mobility for robotic, wheeled vehicles in urban settings. Participants will incorporate their technologies into the OFFSET swarm systems architecture to demonstrate their respective solutions, with field tests taking place in December 2020.

  Shanahan: Super Hornet on track to meet readiness goals, but F-16s and F-22s still struggling

  By: Valerie Insinna WASHINGTON — The Super Hornet is set to meet the 80 percent mission capable rate goal by the end of the year, the Pentagon's top civilian said Wednesday, but it remains unclear whether the F-35, F-22 and F-16 will be able to meet the mark. Last fall, former Defense Secretary Jim Mattis gave the Air Force, Navy and Marine Corps until the end of fiscal year 2019 to bring their F-35s, F/A-18E/F Super Hornets, F-22 Raptors and F-16s up to an 80 percent mission capable rate — a key metric to determine the health of a flying squadron's aircraft. Of those, the “real emphasis was on the F-35 and F/A-18,” acting Defense Secretary Pat Shanahan said May 1 during a House Appropriations Committee panel, and the Super Hornet has made a “tremendous” amount of headway over the past year. “The Navy has made significant progress with the F/A-18s. I think they're on track to meet the goal in September,” he told lawmakers. However, Shanahan suggested that the F-22 and F-16 are unlikely to hit the 80 percent goal, adding that the F-22 “has struggled” and the F-16 “is a bit of a high bar” to clear. Shanahan was unclear on whether the F-35 — which is available in three different variants used by the Air Force, Marine Corp and Navy — will be able to meet the mandate this year. “The F-35s, being brand new aircraft, that [80 percent] should be the baseline where we start,” he said. “The F-35 will come home. We're going to drive that home.” The Air Force, Navy and Marine Corps didn't not provide information about the F-35's progress by press time, but the most recent statistics do not seem promising. The services have stopped publishing mission capable rate statistics last year, citing operational sensitivities, but a March report by the Government Accountability Office found that all variants of the F-35 operated at a mission capable rate of about 50 percent from a period of May to November 2018. However, Mattis' mandate specifies that only the F-35s used by operational squadrons must meet the readiness marker. Because there are only a small number of operational F-35 squadrons, and those units typically have newer and more reliable aircraft, the services may stand a better chance of getting to the 80 percent rate. Air Force spokeswoman Ann Stefanek concurred with Shanahan's assessment of the F-16 and F-22, saying that damage from Hurricane Michael to Tyndall Air Force Base's F-22s and ongoing difficulties with maintaining the F-22's low observable coating were likely to prevent the Raptor from achieving an 80 percent mission capability rate this year. However, the service is still “optimistic” that it will be able to get its F-16s over the finish line by the end of FY19, she said. Given the low availability of tactical aircraft in recent years, it would be a massive accomplishment to get any of the fighter jets to meet the 80 percent goal. In August, Navy Secretary Richard Spencer told reporters that half of the service's Super Hornet aircraft were mission capable — a huge increase from 2017 when two-thirds of the fleet were not available to fly. In 2017, the last year the Air Force put out data, F-22s held a 49 percent mission capable rate and the F-16 hovered around 65 to 70 percent, depending on the model. Despite the services' difficulties meeting the aviation readiness goal, Shanahan maintained that pushing toward an 80 percent mission capable rate for those platforms was a worthy endeavor. “It's a lot of iron to keep on the ground, and given all the training missions and the productivity we can generate, I think holding that standard is smart for now,” he said. https://www.defensenews.com/digital-show-dailies/navy-league/2019/05/01/shanahan-super-hornet-on-track-to-meet-readiness-goals-but-f-16s-and-f-22s-still-struggling
