    Maritime Administration inks a deal for two more multi-mission support ships

    By: David B. Larter WASHINGTON – The Maritime Administration has inked a deal for two more training ships for its prospective Merchant Marine officers in a move that could provide the Navy with a suitable hull for special mission auxiliary ships in the future. MARAD contracted for two additional National Security Multi-Mission Vessels, adding on to the two it purchased last year. The ships are destined for use at Maine Maritime Academy in Castine, Maine, and Texas A&M Maritime Academy in Galveston, Texas. The contract, announced Jan. 19, with Philly Shipyard in Philadelphia, Pennsylvania, is worth approximately $600 million. If the last ship is contracted, it would bring the total buy to $1.5 billion, according to the marine trade publication gCaptain. The NMSVs are also national assets that can be used in humanitarian assistance missions, can accommodate up to 1,000 people and includes a modern medical facility. The vessels could also prove useful in the Navy's quest to identify a flexible hull that can meet a series of missions as it seeks to replace its aging logistics fleet, Sal Mercogliano, a former merchant mariner and maritime historian at Campbell University, told Defense News last year. “Those vessels serve as a potential hull form for maybe a hospital ship, maybe a command ship, an aviation logistics ship, a sub tender: There's potential there,” Mercogliano said. Questions remain around how the Navy will replace some of its special mission ships, such as the aging hospital ships, and the NMSV is worthy of consideration. For moving lots of tanks and howitzers across long distances, the NSMV isn't well-suited. But for many of the other missions the Navy needs to recapitalize, including its hospital ships, it could prove useful. “I don't think they'd be good for a roll-on/roll-off — it's not designed for a large mission bay,” Mercogliano said. “But I think for the hospital ship, a command ship, there's a lot of utility there.” https://www.defensenews.com/naval/2021/01/27/maritime-administration-inks-a-deal-for-two-more-multi-mission-support-ships

    COVID-19: Army Delays Missile Defense Network Test EXCLUSIVE

    The long-awaited IBCS battle network is meant to connect a wide range of Army radars and weapons – and potentially other services' as well – for anti-aircraft and missile defense. By SYDNEY J. FREEDBERG JR. WASHINGTON: The Army has indefinitely postponed a major test of its IBCS air and missile defense network to protect the soldiers and civilians involved from the COVID-19 coronavirus, Breaking Defense has learned. A battalion of air defense troops who'd been training for weeks at White Sands Missile Range have been sent back to home base. Even more important for public health, technical experts from multiple Army agencies and contractors will no longer have to travel to the test. Known formally as a Limited User Test, the event requires participation from across the country, the head of the Army's air & missile defense modernization task force, Bring Gen. Brian Gibson, told me in late March. The LUT would involve both soldiers and civilians from Fort Sill, the Army's artillery & air defense center; Huntsville, headquarters for the service's missile procurement; and extensive support from the host facility, White Sands Missile Range, as well as neighboring El Paso, Tex., Gibson said. Other participants would come from even further afield, such as Army Test & Evalucation Command (ATEC) at Aberdeen Proving Grounds. “There are testers from afar that come in to oversee that test,” Gibson told me. “Those are all variables that are part of this daily assessment on should we, can we, do we continue?” Ironically, the soldiers training for the test were probably safer than the general public – as long as they were isolated in the desert at the vast White Sands Missile Range. But if one of them were somehow exposed to the coronavirus, Gibson warned, the patient would be in close quarters with lots of other soldiers and a long way away from a hospital. “Certainly, being away from large population centers is a different dynamic, [and] most of the time that is positive,” Gibson told me in March, “but, also, we're very cognizant that's still a pretty large number of individuals we have together in tight quarters that are further away from population centers where most of the health care infrastructure and support is.” There have been no reports that any soldiers involved have fallen ill. The test had been scheduled to begin May 15, after weeks of intensive training and preparation. No new date has been set, but if the Army can start the LUT up in July – far from a foregone conclusion – it can keep the high-priority program on schedule. Why IBCS Matters What is IBCS? The name is an awkward nested acronym for Integrated Air & Missile Defense (IAMD) Battle Command System. The network is intended to share data and commands seamlessly among a wide range of historically incompatible systems across the Army and, potentially, the other services. As such, it's the No. 1 priority in the Army's air & missile defense portfolio, which is in turn one of the service's Big Six priority areas for modernize. The program's been in the works for over a decade with many ups, downs and delays, but the Army and lead contractor Northrop Grumman are confident they have turned IBCS around. Four years ago, an earlier — disastrous — Limited User Test revealed software problems that led the Army to delay the program four years and overhaul the entire program. Since that 2016 LUT, the Army and Northrup have been bringing soldiers and engineers together frequently to try out the latest software upgrades and make fixes, rather than waiting for feedback from a major test event. The Army even brought in the Air Force for an experiment in which an F-35A Joint Strike Fighter successfully transmitted targeting data on a missile to IBCS. Compatibility with IBCS is now mandatory for all future Army air & missile defense systems, which has been a stumbling block for the Israeli-made Iron Dome. Top brass have even begun touting IBCS as a key building block of the future Joint All-Domain Command & Control (JADC2) mega-network meant to coordinate all the armed services in a future war with Russia or China. So the Army and Northrop were understandably eager to show off how well the latest version of IBCS performs. When they'll have a chance to do so depends less on what they do themselves than on the progress the entire nation makes against an insidious and invisible enemy. https://breakingdefense.com/2020/04/covid-19-army-delays-missile-defense-network-test-exclusive

    These super-small drones no longer need a battery

    By: Kelsey D. Atherton To be a fly on the wall, an observer must be ubiquitous, unobtrusive and quiet. What if, instead, the observer was just a tiny fly-sized robot, independently powered, able to travel like its insect inspiration? That's one possibility from the long line of work on the RoboBee series of miniature flying machines, the latest of which recently flew independently under its own photovoltaic power. RoboBee is a long-running project of the Harvard Microrobotics Lab and the Wyss Institute for Biologically Inspired Engineering. The end goal is ultimately controlled swarms of insect-sized flying machines, with visions of these swarms performing everything from plant pollination to surveillance. These are ambitious aims, and all have been hindered to this point by a fundamental constraint on the form: the robots are too small to carry batteries. Much of the flight design uses a tethered power supply, allowing the designers to craft Piezoelectric motors that expand and contract as electrical current passes through the muscle-like membranes. This created wings that could flap and propel the robot upward, but it wasn't until recently that the robot could do it on its own power supply. RoboBees are smaller than any drone currently employed by the U.S. military, minute enough to make the palm-sized Black Hornet feel gargantuan. Without a sensor payload, it'd be a novelty, but the military has already invested in cheap, expendable sensor-carrying drone gliders for tasks such as meteorological data collection. Should this power supply enable RoboBees to support a meaningful sensor package, they could be used in a similar fashion, scattered as sensors that can flap their way into a new position. Holding six solar power cells on a stick, and with a second set of wings, the vehicle successfully flew under its own power, even if only for the briefest of moments. The researchers' documentation of their project was published in scientific journal Nature June 26, appearing under the title “Untethered flight of an insect-sized flapping-wing microscale aerial vehicle.” The whole RoboBee weights 259 milligrams, or less than a paperclip, and under special lights was able to generate enough lift to support an additional payload of 70 mg, which could be used for lightweight sensors, control electronics, or larger power supply in the future. Fitting sensors to a craft the small is likely a challenge, but also essential for the promise of the device. There is also the small matter that, even using photovoltaic cells, the robot needs an alien sun to fly. “The Robobee X-Wing needs the power of about three Earth suns to fly, making outdoor flight out of reach for now,” stated the summary from Harvard's School of Engineering and Applied Sciences. “Instead, the researchers simulate that level of sunlight in the lab with halogen lights.” Should the sensors exist, and the device become capable of outdoor flight, microrobotics could become a ubiquitous part of modern life, performing functions alongside insects and relaying sensor information back as an unseen intelligence platform. https://www.c4isrnet.com/unmanned/robotics/2019/07/08/these-super-small-drones-no-longer-need-a-battery/
