Air Mobility Command exercise tests ability to operate in degraded combat environments
By: Diana Stancy Correll
Operating in austere conditions, beyond well-defended bases, is likely in the event of a conflict with a near-peer adversary like Russia or China, according to Air Force leaders.
As a result, the service has increasingly focused on its ability to operate in degraded combat environments the past several years. The biennial Mobility Guardian exercise now underway in Washington state is testing mobility aircraft's readiness to conduct their missions in such contested environments.
For Air Mobility Command's largest readiness exercise, more than 4,000 U.S. and troops, including members of the Air Force, Army, Navy and Marine Corps are now at Fairchild Air Force Base in Spokane and other Western locations to train for airlift, air refueling, aeromedical evacuation and global air mobility support.
The exercise is also designed to sharpen participants' abilities to conduct forcible entry, airfield seizure, strategic deterrence and humanitarian relief operations, according to the service.
As just one example of the kind of training going on, airmen from the 92nd Logistics Readiness Squadron employed a Fuels Operational Readiness Capability Equipment system, marking the first time the mobile fuel bladders have been used stateside in an uncontested environment.
“We use the FORCE to help sustain bare bases and allow for fuel distribution anywhere around the world at a moment's notice,” said Master Sgt. Daniel Rey, 92nd LRS fuels information service center section chief. “The bladder can hold up to 50,000 gallons of fuel, which can help service a wide range of friendly aircraft.”
Meanwhile, at Moses Lake, about 100 miles southwest of Fairchild, airmen from the 621st Contingency Response Wing provided tactical operations center support during a first-of-its-kind Ability to Survive and Operate scenario Sept. 16, according to an Air Force news release.
In the scenario, aircrew from Australia, Canada, New Zealand and the United Kingdom aboard a KC-135 Stratotanker reported chemical contamination while performing an aeromedical evacuation.
The Contingency Response Team at the TOC coordinated ground decontamination support and received the aircraft.
“We provided command and control coverage, access to ramp space and a location to set up a decontamination line for aircrew flight equipment,” said Master Sgt. Jeremiah Ibarra, 321st CRT chief, in the release. “From the tactical operations center we coordinated with the air operations center to get AFE the equipment and supplies they needed.”
CRTs deploy to locations that don't have established air support, and deploy forces that can open and operate an airfield.
“We set up airfields and ramps, communicate aircraft landing, parking, maintenance, refueling and fleet service,” Ibarra said. “To my knowledge this is the biggest CRT operation that has ever happened.”
The CRT is training alongside the 515th Air Mobility Operations Wing, Hickam Air Force Base, Hawaii, and the 521st AMOW, Ramstein Air Base, Germany, at Moses Lake to demonstrate the capability to operate as an integrated team.
“To have the CRT embedded with us here isn't something that we do often, but it has been super beneficial.” said Capt. Jennifer Krutka, officer in-charge of Moses Lake, in the news release. “It has truly been a team effort. We have port airmen learning how to do maintenance and maintenance personnel learning port duties. One of Gen. [Maryanne] Miller's initiatives was to be more versatile airman, and we are doing that here.”
Miller, the head of Air Mobility Command, stressed the significance of the exercise as it related to the 2018 National Defense Strategy at the Air Force Association's Air, Space Cyber conference last week.
“It is imperative that we outpace our adversaries and best position the mobility air forces to defeat the threats of tomorrow,” Miller said.
She also said the exercises align with the command's evolution over the past year into a “warfighting component command” that streamlines the mobility of forces through direct coordinating authority.
“The world has changed and through our transformation efforts, AMC has adapted to meet the growing requirements and accelerated global demands,” Miller said. “As a more agile organization, we have increased our ability to fully leverage the full complement of our mobility resources.”
The Air Force says another element of the exercise is fostering relationships with allies. There are nearly 30 international partners participating in the exercise this year.
“The future of warfare will be increasingly joint,” Lt. Col. Joseph Monaco, director of Mobility Guardian, said in an Air Force news release Sept. 9. “This exercise is an unparalleled opportunity to develop joint-minded airmen who can integrate seamlessly with soldiers, sailors and Marines to compete and if necessary, win amidst great power adversaries.”
The exercise, which kicked off Sept. 8 and concludes Sept. 28, employs aircraft including the KC-10 Extender, KC-135 Stratotanker, C-5 Super Galaxy, C-17 Globemaster III and C-130H/J Hercules and Super Hercules. Of the 4,000 service members, 2,500 are from AMC.

JUST IN: New Navy Lab to Accelerate Autonomy, Robotics Programs
9/8/2020 By Yasmin Tadjdeh Over the past few years, the Navy has been hard at work building a new family of unmanned surface and underwater vehicles through a variety of prototyping efforts. It is now standing up an integration lab to enable the platforms with increased autonomy, officials said Sept. 8. The Rapid Integration Autonomy Lab, or RAIL, is envisioned as a place where the Navy can bring in and test new autonomous capabilities for its robotic vehicles, said Capt. Pete Small, program manager for unmanned maritime systems. “Our Rapid Autonomy Integration Lab concept is really the playground where all the autonomy capabilities and sensors and payloads come together, both to be integrated ... [and] to test them from a cybersecurity perspective and test them from an effectiveness perspective,” Small said during the Association for Unmanned Vehicle Systems International's Unmanned Systems conference, which was held virtually due to the ongoing COVID-19 crisis. Robotics technology is moving at a rapid pace, and platforms will need to have their software and hardware components replaced throughout their lifecycles, he said. In order to facilitate these upgrades, the service will need to integrate the new autonomy software that comes with various payloads and certain autonomy mission capabilities with the existing nuts-and-bolts packages already in the unmanned platforms. “The Rapid Autonomy Integration Lab is where we bring together the platform software, the payload software, the mission software and test them,” he explained. During testing, the service will be able to validate the integration of the software as well as predict the performance of the unmanned vehicles in a way that “we're sure that this is going to work out and give us the capability we want,” Small said. The RAIL concept will rely on modeling-and-simulation technology with software-in-the-loop testing to validate the integration of various autonomous behaviors, sensors and payloads, he said. “We will rely heavily on industry to bring those tools to the RAIL to do the testing that we require,” he noted. However, the lab is not envisioned as a single, brick-and-mortar facility, but rather a network of cloud-based infrastructure and modern software tools. “There will be a certain footprint of the actual software developers who are doing that integration, but we don't see this as a big bricks-and-mortar effort. It's really more of a collaborative effort of a number of people in this space to go make this happen," Small said. The service has kicked off a prototype effort as part of the RAIL initiative where it will take what it calls a “third-party autonomy behavior” that has been developed by the Office of Naval Research and integrate it onto an existing unmanned underwater vehicle that runs on industry-made proprietary software, Small said. Should that go as planned, the Navy plans to apply the concept to numerous programs. For now, the RAIL is a prototyping effort, Small said. “We're still working on developing the budget profile and ... the details behind it,” he said. “We're working on building the programmatic efforts behind it that really are in [fiscal year] '22 and later.” The RAIL is part of a series of “enablers” that will help the sea service get after new unmanned technology, Small said. Others include a concept known as the unmanned maritime autonomy architecture, or UMAA, a common control system and a new data strategy. Cmdr. Jeremiah Anderson, deputy program manager for unmanned underwater vehicles, said an upcoming industry day on Sept. 24 that is focused on UMAA will also feature information about the RAIL. “Half of that day's agenda will really be to get into more of the nuts and bolts about the RAIL itself and about that prototyping effort that's happening this year,” he said. “This is very early in the overall trajectory for the RAIL, but I think this will be a good opportunity to kind of get that message out a little bit more broadly to the stakeholders and answer their questions.” Meanwhile, Small noted that the Navy is making strides within its unmanned portfolio, citing a “tremendous amount of progress that we've made across the board with our entire family of UVS and USVs.” Rear Adm. Casey Moton, program executive officer for unmanned and small combatants, highlighted efforts with the Ghost Fleet Overlord and Sea Hunter platforms, which are unmanned surface vessels. The Navy — working in cooperation with the office of the secretary of defense and the Strategic Capabilities Office — has two Overlord prototypes. Fiscal year 2021, which begins Oct. 1, will be a particularly important period for the platforms, he said. “Our two Overlord vessels have executed a range of autonomous transits and development vignettes,” he said. “We have integrated autonomy software automation systems and perception systems and tested them in increasingly complex increments and vignettes since 2018.” Testing so far has shown the platforms have the ability to perform safe, autonomous navigation in according with the Convention on the International Regulations for Preventing Collisions at Sea, or COLREGS, at varying speeds and sea states, he said. “We are pushing the duration of transits increasingly longer, and we will soon be working up to 30 days,” he said. “Multi-day autonomous transits have occurred in low- and high-traffic density environments.” The vessels have already had interactions with commercial fishing fleets, cargo vessels and recreational craft, he said. The longest transit to date includes a round trip from the Gulf Coast to the East Coast where it conducted more than 181 hours and over 3,193 nautical miles of COLREGS-compliant, autonomous operation, Moton added. Both Overload vessels are slated to conduct extensive testing and experimentation in fiscal year 2021, he said. “These tests will include increasingly long-range transits with more complex autonomous behaviors,” he said. "They will continue to demonstrate automation functions of the machinery control systems, plus health monitoring by a remote supervisory operation center with the expectation of continued USV reliability." The Sea Hunter will also be undergoing numerous fleet exercises and tactical training events in fiscal year 2021. “With the Sea Hunter and the Overlord USVs we will exercise ... control of multiple USVs, test command-and-control, perform as part of surface action groups and train Navy sailors on these platforms, all while developing and refining the fleet-led concept of operations and concept of employment,” Moton said. https://www.nationaldefensemagazine.org/articles/2020/9/8/navy-testing-new-autonomy-integration-lab
