    Use existing and planned craft for unmanned logistical resupply

    By: Wayne Prender and David Phillips To counter expected adversary anti-access/area denial strategies, U.S. naval forces will face significant challenges resupplying dispersed units under emerging distributed operations concepts, particularly in the large geographical distances of the Western Pacific. Future Marine littoral regiments, for example, will require layers of manned and unmanned vessels capable of moving personnel and materiel in decentralized operations to complicate enemy decision-making and targeting. Naval leaders have made clear such decentralized resupply of small, but lethal, expeditionary teams is key to defeating anti-access/area denial threats. With the Department of the Navy already challenged to affordably build and sustain a larger combat fleet, designing, buying and commissioning significant numbers of purpose-built craft solely for this purpose is not ideal. Rather, the Navy should look to adapt fleets of scaled derivative versions of existing or planned naval craft types — particularly those which can be unmanned or optionally manned for specific missions. This option provides the Navy with a greater breadth of capabilities at a more affordable cost. A future fleet of unmanned logistical connectors can leverage existing and planned programs of record. The technology already exists to optionally man or unman such vessels. Appropriately scaled and tailored derivatives of these vessels would conduct logistical cargo missions when required, in addition to performing the existing vital functions the craft already carry out for the fleet. The unmanned logistics fleet would be a necessary adjunct to larger planned manned assets, such as a next-generation light amphibious warship. Naval planners will have to strike a balance between size, capability and affordability. However, even with a lower cost, the vessels must still be large and flexible enough to be capable of performing multiple missions with different payloads. The resulting craft should also be able to reliably operate autonomously over a wide range of environmental conditions at significant distances, have a light logistics footprint and possess sufficient cargo-carrying capacity. Rather than a homogeneous unmanned cargo fleet, the Navy could instead utilize several derivatives of existing vessels it already operates or has planned, which will ease any additional maintenance or training burden. Marines operating in the wide-open spaces of the Western Pacific might, for example, use larger variants capable of hauling cargo over greater distances, while units in other geographic locations are equipped with smaller versions more appropriate for their specific environments. The ability to repurpose multiple craft types would allow a more diverse fleet composition of manned and unmanned vessels teamed for mission-tailored flexibility. Moreover, craft that can accommodate interchangeable payloads would also be available to naval planners for additional missions. For example, the vessels could be equipped with a variety of intelligence, surveillance and reconnaissance sensors to improve fleet situational awareness while also performing the cargo resupply missions. Buying scaled derivatives of existing program craft will bring additional benefits, including cost savings through economies of scale for acquisition, while minimizing any upfront developmental costs, as hull forms, key components and systems largely already exist. Moreover, because much of the basic systems and components will be common, training, maintenance and repair functions can be streamlined, adding yet more savings over the vessels' life cycles. Likewise, the technologies for unmanning and optionally manning are well along in their development, while autonomous behaviors and autonomy technologies developed for other programs can be reused rather than having to be created anew. For example, autonomous behaviors and control technologies developed for unmanned aircraft systems can be leveraged for naval applications, while similar autonomy technologies for unmanned ground vehicles are also progressing. Within the naval domain, experimentation such as Advanced Naval Technology Exercise 2019 and Exercise Citadel Shield-Solid Curtain earlier this year have already demonstrated that unmanned surface vessels can autonomously station keep, navigate around obstacles, protect high-value assets and conduct other necessary core functions. As autonomy technologies further develop, unmanned naval craft of the size and complexity envisioned for logistics and cargo hauling will be able to add new missions and functionality. Longer term, delivery of logistical payloads to Marines on a beachhead can be done completely with unmanned platforms. For example, small to medium robotic ground vehicles loaded with supplies could be carried by one of these unmanned logistical craft. Rather than Marines exposing themselves to hostile fire while unloading supplies on the beach, robotic ground vehicles or aerial drones disembark from the vessels and deliver cargo directly to the Marines in a more secure location. Such vehicles need not be fully autonomous, but rather could be partially autonomous or remotely operated from the security of the protected location. While many details of this concept require further exploration and refinement, conducting experimentation to bring truly multidomain capabilities to bear on the resupply challenge is a worthy endeavor. Getting these and related technologies into the hands of sailors, Marines and other U.S. forces to test and refine will be the quickest and most fruitful way to develop the new concepts and field the necessary capabilities.

    Four companies win contracts to build the Air Force’s Skyborg drone

    By: Valerie Insinna WASHINGTON — Boeing, Northrop Grumman, General Atomics and Kratos will move forward in the Air Force program to build an AI-enabled drone wingman known as Skyborg. Each company Thursday was awarded an indefinite-delivery/indefinite-quantity contract worth up to $400 million, but no seed money was immediately allocated as the firms will have to compete against each other for future orders. Through the Skyborg program, the Air Force wants to field a family of unmanned aerial systems that use artificial intelligence to adapt to battlefield conditions. The Skyborg drone should be cheap enough where the loss of aircraft in combat could be sustained, yet survivable enough so that it could move into a high-end fight and function as a wingman to manned fighter jets. “Because autonomous systems can support missions that are too strenuous or dangerous for manned crews, Skyborg can increase capability significantly and be a force multiplier for the Air Force,” said Brig. Gen. Dale White, who leads the Air Force's program office for fighters and advanced aircraft. “We have the opportunity to transform our warfighting capabilities and change the way we fight and the way we employ air power.” Air Force acquisition executive Will Roper has said that Skyborg could eventually become smart enough that, like R2-D2 in the Star Wars films, it can autonomously present information and conduct tasks to help decrease fighter pilot workload. The system learns from prior experiences how best to support human pilots. But in the near term, the Air Force wants to use the Skyborg program to integrate an autonomous air vehicle with open mission systems as a way to demonstrate that it can team with a manned fighter, the service said in a statement. “Autonomy technologies in Skyborg's portfolio will range from simple play-book algorithms to advanced team decision making and will include on-ramp opportunities for artificial intelligence technologies,” said Brig. Gen. Heather Pringle, the Air Force Research Laboratory commander. “This effort will provide a foundational government reference architecture for a family of layered, autonomous, and open-architecture UAS.” https://www.defensenews.com/unmanned/2020/07/23/four-companies-got-contracts-to-build-the-air-forces-skyborg-drone

  • Harnessing Quantum Technologies at Room Temperature

    Harnessing Quantum Technologies at Room Temperature

    Quantum research in both information science and sensing shows great promise for enabling a host of new defense applications. A major hindrance to transitioning breakthroughs from the laboratory to practical use, however, is the extensive equipment needed to cool and trap atoms to exploit their quantum features. To address this challenge, DARPA has announced its Science of Atomic Vapors for New Technologies (SAVaNT) program. SAVaNT seeks to advance the performance of room-temperature atomic vapors to enable future opportunities for unprecedented combinations of low size, weight, and power (SWaP) with performance across multiple Department of Defense domains. “The SAVaNT program will explore a new suite of technologies based on room-temperature atomic vapors to address important gaps for military-relevant applications,” said Tatjana Curcic, program manager in DARPA's Defense Sciences Office. “We're interested in innovative research proposals that significantly advance the performance of atomic vapors for electric field sensing and imaging, magnetic field sensing, and quantum information science.” The program is focused on warm atomic vapors as opposed to cold-atom technology, which requires cooling atoms to very low temperatures with lasers to reduce thermal noise. This process has enabled the world's most accurate atomic clocks with unprecedented levels of timing precision. But the apparatuses needed to cool the atoms can fill up a laboratory, making laboratory atomic clocks impractical for field use. The warm atomic vapors approach, on the other hand, doesn't require complex laser-cooling and allows for a larger number of atoms, boosting the signal. The challenge, however, is that thermal environment effects – even at room temperature – significantly mitigate how long the quantum effects, or coherence, can last. SaVaNT researchers will demonstrate novel methods in three technical areas to overcome limitations due to thermal effects: Technical Area 1 seeks to develop a Rydberg sensor – which uses atoms to sense electric fields – that would provide ultra-narrow bandwidth, high-sensitivity electric field detection for millimeter waves. Technical Area 2 focuses on Vector Magnetometry to enable low-SWaP, room-temperature, quasi-DC magnetic field sensors. The third technical area will address vapor quantum electrodynamics to enable critical components for quantum networks at room temperature. Current methods require either cryogenics or laser cooling and trapping. A Proposers Day for interested proposers will be held virtually via webinar on Sept. 3.
