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.”

  • KC-135s and C-130Js are the next aircraft to enter the Air Force’s data-driven maintenance program

    KC-135s and C-130Js are the next aircraft to enter the Air Force’s data-driven maintenance program

    By: Jeff Martin The KC-135 refueling tanker and the C-130J airlifter will be the next two aircraft to be part of the Air Force's predictive maintenance program, part of the service's effort to do maintenance before airplanes break--and improve mission capable and availability rates, according to Air Mobility Command's logistics director. "The bottom line is to get to where we are scheduling all of our maintenance, rather than reacting to the maintenance,' said Brig. Gen. Steven Blaymaier, who oversees Air Mobility Command's logistics, engineering and force protection, in an interview at the 2018 Airlift Tanker Association symposium outside Dallas, Texas. “We want our units to achieve their mission-capable rates on a sustained basis.” According to the latest available data, from FY2017, the KC-135 fleet had, on average, a 74 percent mission capable rate, and the C-130J fleet had a 77 percent mission capable rate. As for the rest of the mobility fleet, by that same data, the C-5M fleet stood at 60 percent, the C-130H fleet was at 73 percent, and the C-17 fleet was at 84 percent mission capable. The concept, known as conditions based maintenance, has already been rolled out to the C-5 fleet within AMC, and the B-1 fleet in Air Force Global Strike Command. It uses algorithms based on reams of data to create models to predict when a part might break, rather than waiting for it to fail. Its a standard practice in the commercial aviation industry, and is now making its way into the Air Force. Blaymaier says the KC-135 fleet will join the program in spring of 2019, and the C-130J fleet will follow in the summer. Blaymaier also added that the other aircraft in AMC's fleet would be joining the program eventually, like the C-17 and KC-10. “They're all in work at their program offices right now,” he said. “What we learn from C-5 will be incorporated into the other aircraft.” Blaymaier also said the Air Force was modelling their effort after Delta Airlines's Tech Ops division's procedures, and that the service was at the beginning or “crawl stage” of the process. He also noted that Delta took “eight years” to get achieve the results they were looking for, and that the Air Force was working on that path. In September, Lt. Gen. Robert McMurray, commander of the Air Force Sustainment Center, told Defense News that the conditions-based maintenance program was critical to increasing the readiness of the Air Force's aircraft. "Given the aging fleet situation that we have, we probably need to be using data better to take care of it — which is a drive toward what most everyone right now is saying is the right way to manage fleet sustainment, which is through condition-based maintenance and data analytics,” he said at the time. Another benefit Blaymaier described was that the service will be able to track maintenance needs by individual aircraft, rather than by a general fleet-wide standard. That could reduce time in depots and increase mission capable rates, a top priority of senior Pentagon leaders. “As we move forward with conditions based maintenance plus (CBM+) and predictive analytics, we'll be able to know by tail number which parts are going to fail on certain aircraft," he said."It'll be much more surgical [and] operational." Blaymaier added that while the transition to conditions based maintenance might be a long journey, it would lead to huge benefits for the Air Force. “Ultimately we want to achieve those aircraft availability standards that we established for each of our fleets that are required to meet our wartime taskings,” he said. https://www.defensenews.com/digital-show-dailies/airlift-tanker-annual/2018/10/27/kc-135s-and-c-130js-are-the-next-aircraft-to-enter-the-air-forces-data-driven-maintenance-program
