  Watchdog: 75 percent of sub and aircraft carrier maintenance ended late in recent years

  Geoff Ziezulewicz While the U.S. Navy has spent nearly $3 billion to improve shipyard maintenance performance in recent years, “the shipyards continue to face persistent and substantial maintenance delays that hinder the readiness of aircraft carriers and submarines,” according to a government watchdog report released this week. Three-quarters of the 51 aircraft carrier and submarine maintenance periods from fiscal 2015 to 2019 were completed late, resulting in 7,425 days of delays, according to the report by the Government Accountability Office. The Navy's four shipyards — in Portsmouth, Virginia; Kittery, Maine; Honolulu, Hawaii; and Bremerton, Washington — provide vital maintenance that includes ship overhauls, nuclear refueling, alterations and refits, among other duties. The aircraft carrier maintenance periods that ended late exceeded their deadlines by an average of 113 days, the GAO reports, while submarine maintenance periods ending late missed the mark by an average of 225 days. Such availabilities last anywhere from six months to three years, and when they don't end on time, it gums up the entire system, delaying other maintenance periods, deployments and other needs. The main factors leading to the tardiness had to do with shipyard workforce performance and having enough people to perform the vital work, the GAO found. Unplanned work, or tasks identified after finalizing maintenance plans, was also cited as a significant factor resulting in the delays. While the Navy has taken steps to address such delays, the sea service has yet to fully address the unplanned work and workforce factors causing the majority of delays, according to the GAO. https://www.navytimes.com/news/your-navy/2020/08/21/watchdog-75-percent-of-sub-and-aircraft-carrier-maintenance-ended-late-in-recent-years/

  DARPA: With Insights from Integration Exercise, SubT Challenge Competitors Prepare for Tunnel Circuit

  Nine teams hailing from four continents gathered in Idaho Springs, Colorado, the week of April 5-11, 2019, to test autonomous air and ground systems for navigating the dark, dangerous, dirty, and unpredictable underground domain. The SubT Integration Exercise, known as STIX, took place at the Colorado School of Mines' Edgar Experimental Mine. The event provided a shakeout opportunity for competitors in advance of the Tunnel Circuit in August, the first of three subdomains that teams will tackle in DARPA's Subterranean Challenge. The teams were divided into three groups. Each group had one day to experiment with their various systems during multiple runs in the mine, followed by a second day in which each team attempted a one-hour mock, scored run. Teams could earn points by accurately locating, identifying, and reporting artifacts placed within the tunnels. Artifacts included thermal manikins, backpacks, fire extinguishers, cell phones, and cordless drills – all inspired by objects an end user such as a warfighter or first responder might encounter. The mine environment presented teams with low light, high dust, metal rails, and irregular terrain. The DARPA team added to the complexity with a theatrical smoke machine, which mimicked real smoke a warfighter or first responder could contend with in an emergency response scenario, for example. “It was amazing to see the progression from day one into day two for each team as they explored the tunnels of the mine and began to understand just how complex and unknown these underground environments can be,” said Timothy Chung, program manager for the Subterranean Challenge in DARPA's Tactical Technology Office. “It's not just about testing whether there's enough light or if robots can drive a few meters. It's about how all that has to come together in a difficult environment and the teams are experiencing the challenge of integration in addition to technology development.” The competitors at STIX included a mix of DARPA-funded and self-funded teams: CERBERUS University of Nevada, Reno ETH Zurich, Switzerland Sierra Nevada Corporation University of California, Berkeley Flyability, Switzerland CoStar: Collaborative SubTerranean Autonomous Resilient Robots Jet Propulsion Laboratory California Institute of Technology Massachusetts Institute of Technology KAIST, South Korea CRETISE: Collaborative Robot Exploration and Teaming In Subterranean Environments Endeavor Robotics Neya Systems CSIRO Data 61 Commonwealth Scientific and Industrial Research Organisation, Australia Emesent, Australia Georgia Institute of Technology CTU-CRAS Czech Technical University in Prague, Czech Republic Université Laval, Canada Explorer Carnegie Mellon University Oregon State University MARBLE: Multi-agent Autonomy with Radar-Based Localization for Exploration University of Colorado, Boulder University of Colorado, Denver Scientific Systems Company, Inc. PLUTO: Pennsylvania Laboratory for Underground Tunnel Operations University of Pennsylvania Exyn Technologies Ghost Robotics Robotika Robotika.cz, Czech Republic Czech University of Life Science, Czech Republic Following the Tunnel Circuit, teams will compete in the Urban Circuit, which will focus on underground urban environments such as mass transit and municipal infrastructure; and the Cave Circuit, which will focus on naturally occurring cave networks. Locations for the circuit events have not been announced. Qualification is ongoing for the circuit events. Requirements can be found in the SubT Qualification Guide available on the Resources Page. Teams interested in joining either the virtual or systems tracks can still register and are encouraged to join the SubT Community Forum to exchange ideas, explore teaming opportunities, and receive updates on the Challenge.

  Allies target early AUKUS milestones to keep 20-year plan on track

  Australia, the U.K. and the U.S. have been hard at work since March to get the decades-long AUKUS submarine collaboration plan off to a strong start.
