Navy Wants Robot Boats But Will Still Need Sailors To Fix Them

"We need to find a balance of vehicle designs that enables the cost to be cheap enough that we can afford them, but it's not so highly optimized towards the purely unmanned spectrum that it's cost prohibitive to maintain them."

WASHINGTON: The Navy needs to comb through a host of thorny issues before deploying a new fleet of unmanned ships to confront China, Russia, and Iran.

“You don't hear me talking about artificial intelligence and machine learning and things like that just yet,” said Capt. Pete Small, the Navy's program manager for Unmanned Maritime Systems at a C4ISRnet conference this morning. “Those aren't my first concerns. My first concerns are about the field stability and sustainability of these systems right now.”

The Navy just isn't equipped to deploy or sustain a new fleet of unmanned vessels yet. “Our infrastructure right now is optimized around manned warships,” Small said. “We're gonna have to shift that infrastructure for how we prepare, deploy, and transit” over large bodies of water before large numbers of unmanned vessels can be effective, he said.

It's not clear where that planning stands, but the service has already invested tens of millions in the early work of developing a family of large and medium unmanned vessels, and is looking to vastly ramp that up in the 2021 budget, asking for $580 million for research and development.

In 2019 an unmanned Sea Hunter prototype autonomous vessel sailed from San Diego to Hawaii, but it needed to repair several broken systems along the way, forcing sailors to board the ship. It was the first experiment of its kind, one the Navy has not repeated. Those mechanical problems point to work the Navy must do to reconfigure its logistics tail to meet the needs of a new class of ship.

“We're going to have to transition from a [system] more optimized around our manned fleet infrastructure to a more distributed mix of these large manned platforms to smaller platforms,” Small said, “we're gonna need to talk about things like, tenders for heavy lift ships, or forward operating bases, things like that.”

The early thinking is the service will use the ships as sensors deployed well forward of manned ships and carrier strike groups, which could be at risk if they maneuvered too close to contested waters. But the Navy isn't going to pin everything on a nascent fleet of robot boats — a new class of manned frigates is also being built to operate inside the range of enemy precision weapons. The frigates are going to be smaller and faster than current destroyers, with the ability to generate much more power so they can use lasers and other weapons for both offensive and defensive missions.

The Navy is considering several sizes of USVs, including a large variant between 200 and 300 feet in length and having full load displacements of 1,000 tons to 2,000 tons. The ships should be low-cost, and reconfigurable with lots of room capacity for carrying various payloads, including mine hunting and anti-surface warfare.

The 2021 budget submission proposes using research and development funding to acquire two more prototypes and another in 2022. Plans then call for buying deployable LUSVs at a rate of two per year.

Medium unmanned ships will likely come in at between 45 to 190 feet long, with displacements of roughly 500 tons. The medium ships are thought to skew more toward mission modules revolving around intelligence, surveillance and reconnaissance payloads and electronic warfare systems. The first MUSV prototype was funded in 2019, and the Navy wants to fund a second prototype in 2023.

Fundamental issues need to be sorted out before the Navy buys one of these ships.

“We need to find a balance of vehicle designs that enables the cost to be cheap enough that we can afford them, but it's not so highly optimized towards the purely unmanned spectrum that it's cost prohibitive to maintain them,” Small said. If the maintenance is too complicated and time consuming, and “we have to take the whole vehicle out of the water and take it apart in some explicit manner to replace the parts, it's not gonna really support what we need in the field. So really, the sustainability of the technology is as important — if not more important — in the near-term than the technology itself.”

    DARPA wants a robotic satellite mechanic launched by 2022

    By: Nathan Strout   The Defense Advanced Research Projects Agency is on track to announce a new commercial partner for its robotic servicing payload by the end of the year, with plans to have a spacecraft in orbit in 2022. “I'm standing here with a smile on my face. The program is moving forward and things are looking good and we're very hopeful,” Joe Parrish, program manager for the Robotic Servicing of Geosynchronous Spacecraft program at DARPA, said at the 2019 Global Satellite Servicing Forum Oct. 1. “We're looking to launch RSGS in late 2022.” RSGS is intended to deliver a GEO spacecraft with a payload consisting of two large 2 meter arms and a number of tools that will allow it to perform maintenance and other work on satellites in GEO. The spacecraft will perform four main functions in space: inspection, orbital adjustments, anomaly resolution and installation of self-contained payloads. With a host of cameras onboard, RSGS will be able to inspect other satellites. This can help operators on the ground diagnose problems and inform in-orbit repairs. It can also use its arms to capture a satellite and move it, either to a new orbit or to dispose of it. DARPA envisions RSGS being able, again using its arms, to install new payloads on existing satellites, replacing legacy hardware and augmenting its mission for years to come. And, of course, RSGS will be available to traverse the GEO landscape to help satellites that fail to deploy correctly. “If somebody launches up into GEO while we're up there and a solar array fails to deploy or a reflector or antenna fails to deploy, we can come galloping to the rescue,” said Perrish. “The benefit is not to demonstrate robot arms waving around in space. The benefit is to increase the resilience of our infrastructure in space.” While DARPA is developing the payload with robotic arms, according to Parrish, DARPA needs a commercial partner to build the spacecraft that will house the payload and carry it around in orbit. “We're looking for the partner to provide the spacecraft bus — so using a heritage GEO bus that may have had some tailoring for RSGS requirements, integrating the payload and the spacecraft bus together, procuring and launching that integrated spacecraft to GEO, and then providing mission control center for operations for a long period of time,” explained Parrish. Parrish said that the full project would be turned over in due time to the commercial partner to operate RSGS for fun and profit. But DARPA has hit some stumbling blocks in securing that commercial partner. In 2017, Orbital ATK sued DARPA to stop it from developing what it saw as competition to its own satellite servicing space vehicle. While that effort failed, the company's efforts to develop its own satellite servicing program have continued. Orbital ATK was acquired by Northrop Grumman in 2018, and now the Northrop Grumman subsidiary SpaceLogistics is preparing to launch the first satellite life extension vehicle into space in the coming weeks. Then, in January, Maxar Technologies' Space Systems Loral pulled out of an agreement with DARPA to build the spacecraft to host the RSGS payload as the company moved out of the GEO construction market. DARPA has spent much of the last year working to find a new commercial partner. In May they hosted a Proposer's Day to discuss the program with potentially interested companies, and now Parrish says they expect to announce a partner toward the end of the year. “2019 has been quite a year,” said Parrish. “We are still in source selection for a new commercial partner.” Meanwhile, work on the payload itself is ongoing. The first of two flight robotic manipulator arms is in final assembly and will be shipped to the Naval Research Lab in the next two weeks, where it will be integrated into the payload. The second arm lags the first by about two months, said Parrish, and is currently in assembly. In 2020, all of the components of the payload will be sent to NRL for assembly into the actual payload. https://www.c4isrnet.com/battlefield-tech/space/2019/10/03/darpa-wants-a-robotic-satellite-mechanic-launched-by-2022/

    Gen. Milley is right: The US Army is on the mend

    Last month, in an appearance before the Defense Subcommittee of the Senate Appropriations Committee, Chief of Staff of the U.S. Army Gen. Mark Milley provided a notably upbeat assessment of the state of his service. “The Army is on the mend. I can report out to you today, after two and a half years as the chief of staff of the Army, we are in significantly better shape than we were just a short time ago. And that is through the generosity of this Congress and the American people,” he said. Clearly, some of the credit for the Army's improved state of affairs is a result of the recently passed two-year budget, which provided a much-needed increase in resources. The Army has been able to grow its end strength, purchase needed munitions and spare parts, increase training activities, and recapitalize older and damaged equipment. More resources have also enabled the Army force to expand its presence in Europe, increase, albeit modestly, procurement of upgraded Abrams tanks, Bradley Fighting Vehicles and Strykers, and acquire the new Armored Multi-Purpose Vehicle. But much of the credit goes to the Army chief of staff himself. About a year and a half ago, I wrote a blog for the National Interest titled “Perhaps the Most Remarkable CSA in More than Half a Century.” It was Gen. Milley who made modernization the measure of success for his tenure as the Army chief of staff. This change in strategic direction came just in time, ahead of the reappearance of great power competition as the greatest threat to this nation's security. Gen. Milley is not alone in his quest. In fact, it is a troika consisting of Secretary of the Army Mark Esper, Under Secretary of the Army Ryan McCarty and the chief that is fashioning a new Army in record time and doing so while simultaneously transforming the Army's acquisition system. This is the proverbial case of changing the car's tires while speeding down the road. The early signs are that the Army modernization is on the mend and the acquisition system is being changed. An important example of these improvements is the Army's Rapid Capabilities Office. Established by the secretary and the chief in August 2016, the RCO is tasked to expedite critical capabilities to the field to meet combatant commanders' needs using alternative contracting mechanisms to deliver technologies in real time to the war fighter. One of the RCO's initial projects was to bring the Army back into the game with respect to electronic warfare. In 12 months, the RCO developed an initial integrated mounted and dismounted EW sensor capability that has been deployed with U.S. forces in Europe. A second phase of the project is underway that will add aerial sensors, additional ground-unit sets and improve functionality. Another program that is proceeding rapidly is a vehicle-mounted, jam-resistant positioning, navigation and timing capability for GPS-challenged environments. Prospective solutions are currently undergoing testing. The chief has directed the RCO to address several new areas. The RCO is working on a long-range cannon concept that may be able to double the range of 155mm howitzers, as well as optical augmentation technology to detect an adversary's anti-tank guided missile day/night sights and loitering munitions that can strike air-defense and artillery emplacements. The Army has been moving rapidly to address many of its critical capability gaps. To meet the challenge posed by hostile aircraft and drones, the Army intends to deploy the first battery of the Maneuver Short Range Air Defense launcher on a Stryker armored vehicle by 2020, five years ahead of schedule. Additional sensors and weapons, including a tactical laser, could be integrated into the new turret by the early 2020s. Tank-automotive and Armaments Command did a rapid assessment of active protection systems. The current plan is to equip at least four brigades of Abrams tanks with the Israeli Trophy system while testing continues on a number of solutions for other armored fighting vehicles. The Army also has used other rapid procurement organizations within the Pentagon. One of these is the Defense Innovation Unit Experimental, created in 2016 to push rapid innovation based on leveraging commercial companies. Recently, DIUx led a prototype contract involving upgrades for Bradley Fighting Vehicles. The first production items from it will soon be delivered to the 1st Cavalry Division at Fort Hood, Texas. There are other examples of advances in cyberwarfare, soldier systems, networking and long-range precision fires. The central point is that Gen. Milley's vision of the Army's future is turning out to be right. https://www.defensenews.com/land/2018/06/13/gen-milley-is-right-the-us-army-is-on-the-mend/
