Why Unmanned Systems Are The Go-To Option for Gray Zone Ops in the Gulf

Securing the Gulf Topic Week

By Heiko Borchert

Introduction

Current incidents in the Arabian Sea should be seized as an opportunity to advance naval conceptual thinking about unmanned maritime systems in gray zone operations. Gray zone activities are an astute object for concept development, as they “creep up on their goals gradually,” rather than involving decisive moves, as Michael Mazarr has argued. In response, Mazarr contends, gray zone operations will “call for a greater emphasis on innovation” as these operations take different forms and intensities and thus require varied responses. This coincides with the general need to devote more attention to concepts development that drives the use of new naval technologies such as unmanned systems.

Applying Unmanned Systems to Gulf Security

Maritime stability in the Arabian Sea has deteriorated significantly over the past couple of weeks. In response to the Iranian seizure of the Stena Imperio, a Swedish oil tanker under British flag, London reached out to different European capitals in view of establishing a maritime protection mission escorting commercial vessels through the Strait of Hormuz.

This incident and prior events in the Arabian Sea such as harassing commercial vessels with speedboats and assaults on commercial vessels are a perfect illustration of so-called gray zone activities. Located between war and peace, gray zone activities involve “coercive actions to change the status quo below a threshold that, in most cases, would prompt a conventional military response,” as Lyle J. Morris and others have suggested.

These activities raise an obvious question: How best to respond? Staying out of the region for an interim period, as the British government has advised U.K. shipping, has been interpreted as a watershed moment “when the UK admits it can no longer protect its merchant vessels.” But even if political support for the maritime protection mission matured, the question would remain if there were enough adequate platforms to do the job.

Deploying big capital ships or surface combatants to escort merchant vessels might send a strong message of resolve to Iran, but doubts remain if this approach is adequate. Past experiences in the Arabian Sea have made it clear that naval vessels remain vulnerable to speedboats operating at a high tempo in distributed maneuver operations. While this is certainly only one method of attack, it is most important for strategic communication. Small boats successfully attacking or deterring prestigious naval ships delivers a message that all gray zone actors want to convey.

It is time to supply navies with an additional option using unmanned systems. Unmanned maritime systems (UMS) have been developed and used for quite some time, but right now, the majority of unmanned maritime systems are used for mine countermeasures. There is an obvious operational need to do the job, concepts of operations are in place, and technology is mature. This makes a perfect fit, but more can be done.

Unlike gray zone activities in the South China Sea that involve the building of artificial islands to underline sovereignty claims and the use of naval militia and the coast guard to intimidate neighbors, Iran’s actions are of a different quality. In the Arabian Sea, mosaic defense emphasizes mass, speed, and surprise. Unmanned maritime systems would be ideal to respond because they can be built to be lost. This levels out current asymmetries between speed boats and big capital ships and denies the adversary the offensive on strategic communications. This attrition-like role is only one mission UMS could play in future maritime protection missions. Overall, the mission envelope could be much broader.

First, assuming that a maritime protection mission depends on persistent situational awareness and understanding, unmanned systems can be used to collect intelligence and provide reconnaissance. For this mission the emphasis should be on closing the sensor chain from seabed activities through the undersea world to the sea surface into airspace and space. In all of these domains unmanned systems are already in use, but more needs to be done to fuse data to augment the existing Recognized Maritime Pictures (RMP), for example to detect anomalies stemming from adversarial behavior at sea.

Second, unmanned systems at sea can push the defense perimeter out. Forward deployed unmanned surface vehicles (USV) could be used to intimidate an adversary’s embarking speed boat fleet thus delaying the launch of operations and creating “noise” that would send alarms to the RMP. A more wicked though not yet technically mature option would focus on very small, mine-like unmanned underwater vehicles (UUV). These assets could be deployed covertly by submarines or by air assets. These UUV could turn into a sort of adhesive explosives that stick to boats running over them, thus rendering them dysfunctional.

Third, unmanned maritime systems could be used for deception operations. A swarm of USV could enter a theater of operation disguised as a big capital ship on the adversary’s sensors. As the adversary prepares to counter the ship the USV swarm would disperse into many different smaller platforms thus out tricking the adversarial defense posture. A similar mission can be envisaged for the underwater domain where UUV are already used to imitate the signature of submarines.

Fourth, USVs could constitute the outer ring of maritime protection missions. Robust platforms could be equipped with remote-controlled weapon stations, like the Protector USV developed by Rafael Advanced Systems, to engage incoming speed boats or flying platforms. In addition, USV could be used to deploy electronic counter-measures, for example, to jam adversarial sensors and take out communications between unmanned aerial assets and the respective control units. 

Conclusion

While some of these ideas are closer to reality than others, what matters most is that concepts and operational requirements need to drive the use of unmanned maritime systems in gray zone operations. So far, the discussion about UMS mainly focuses on providing solutions to meet the needs that emerge in naval warfare areas such as mine countermeasures, anti-submarine warfare, or anti-surface warfare. However, gray zone activities cut across all of these tasks. Adequate responses need to adopt a more horizontal approach, as well looking at the technological building blocks that can be used for all missions. Here, the most recent decision of Belgium and the Netherlands to develop a toolbox of unmanned systems for mine-countermeasures shows the way to the future. This approach could be turned into a holistic concept to deal with UMS for maritime gray zone activities.

Putting extra emphasis on innovation and concepts development also opens up avenues for fruitful cooperation with the Gulf states that step up efforts to expand their own naval capabilities while at the same time ramping up efforts to establish a local naval industrial base. Involving them from the start would make sure that specific regional requirements could be adequately addressed while at the same time contributing toward building up local technology expertise in important  areas and incentivizing the establishment of local capabilities and concepts. In the long run this joint approach could help shoulder the burden to provide maritime stability in one of the world’s most pivotal regions.

U.S.-China Tensions and How Unmanned Military Craft Raise the Risk of War

This article originally featured in the Nikkei Asian Review under the title, “US-China tensions — unmanned military craft raise risk of war,” and is republished with permission. Read it in its original form here.

By Evan Karlik

The immediate danger from militarized artificial intelligence isn’t hordes of killer robots, nor the exponential pace of a new arms race.

As recent events in the Strait of Hormuz indicate, the bigger risk is the fact that autonomous military craft make for temping targets – and increase the potential for miscalculation on and above the high seas.

While less provocative than planes, vehicles, or ships with human crew or troops aboard, unmanned systems are also perceived as relatively expendable. Danger arises when they lower the threshold for military action.

It is a development with serious implications in volatile regions far beyond the Gulf – not least the South China Sea, where the U.S. has recently confronted both China and Russia.

If China dispatched a billion-dollar U.S. destroyer and a portion of its crew to the bottom of the Taiwan Strait, a war declaration from Washington and mobilization to the region would undoubtedly follow. But should a Chinese missile suddenly destroy an orbiting, billion-dollar U.S. intelligence satellite, the White House and the U.S. Congress might opt to avoid immediate escalation.

“Satellites have no mothers,” quip space policy experts, and the same is true for airborne drones and unmanned ships. Their demise does not call for pallbearers, headstones, or memorial statues.

As autonomous systems proliferate in the air and on the ocean, military commanders may feel emboldened to strike these platforms, expecting lower repercussions by avoiding the loss of human life.

Consider when Chinese naval personnel in a small boat seized an unmanned American underwater survey glider in the sea approximately 100 kilometers off the Philippines in December 2016. The winged, torpedo-shaped unit was within sight of its handlers aboard the U.S. Navy oceanographic vessel Bowditch, who gaped in astonishment as it was summarily hoisted aboard a Chinese warship less than a kilometer distant. The U.S. responded with a diplomatic démarche and congressional opprobrium, and the glider was returned within the week.

Lately, both Chinese and Russian navies in the Western Pacific have shown themselves bolder than ever. Early in June, south of Okinawa, the Russian destroyer Admiral Vinogradov came within tens of meters of the U.S. guided-missile cruiser Chancellorsville.

In September 2018, the American destroyer Decatur conducted a freedom of navigation transit near the disputed Spratly Islands in the South China Sea; it nearly collided with a Chinese destroyer attempting to ‘shoulder’ the American vessel off its course through these hotly contested waters.

In coming years, the Chinese military will find increasingly plentiful opportunities to intercept American autonomous systems. The 40-meter prototype trimaran Sea Hunter, an experimental submarine-tracking vessel, recently transited between Hawaii and San Diego without human intervention. It has yet to be used operationally, but it is only a matter of time before such vessels are deployed.

The U.S. Navy’s nearly $3 billion ‘Ghost Fleet’ initiative aims to develop a total of 10, 2,000-ton unmanned warships. Boeing recently edged out Lockheed Martin to begin construction of four extra-large unmanned undersea vehicles, each capable of transiting twelve thousand kilometers autonomously, for $43 million.

China’s navy may find intercepting such unmanned and unchaperoned surface vessels or mini-submarines too tantalizing to pass up, especially if Washington’s meek retort to the 2016 glider incident is seen as an indication of American permissiveness or timidity.

With a captive vessel, persevering Chinese technicians could attempt to bypass anti-tamper mechanisms, and if successful, proceed to siphon off communication codes or proprietary artificial intelligence software, download navigational data or pre-programmed rules of engagement, or probe for cyber vulnerabilities that could be exploited against similar vehicles.

No doubt Beijing is closely watching how the Trump administration responds to Iran’s downing of a Global Hawk surveillance drone on June 20, assessing U.S. willingness to punch back in kind, or to escalate.

Nearly 100,000 ships transit the strategically vital Singapore Strait annually, where more than 75 collisions or groundings occurred last year alone. In such congested international sea lanes, declaring a foreign navy’s autonomous vessel wayward or unresponsive would easily serve as convenient rationale for towing it into territorial waters for impoundment, or for boarding it straightaway.

More than 4,000 AI and robotics researchers have joined an open letter advocating a ban on autonomous offensive weapons that function without human supervision, and this past March, the U.N. Secretary-General decried such machines as “politically unacceptable, morally repugnant,” and worthy of international prohibition.

Such limits or controls on artificial intelligence would be immensely more difficult to verify when compared to existing inspection regimes for nuclear missiles or centrifuges. In the meantime, urgent action is needed.

A memorandum of understanding signed five years ago by the U.S. Department of Defense and the Chinese defense ministry, as well as the collaborative code of naval conduct created at the 2014 Western Pacific Naval Symposium, should be updated with an expanded right-of-way hierarchy and non-interference standards to clarify how manned ships and aircraft should interact with their autonomous counterparts. Without such guidance, the risk of miscalculation increases.

An incident without any immediate human presence or losses could nonetheless trigger unexpected escalation and spark the next conflict.

We should fear that, much more than killer robots.

Why We Will Never See Fully Autonomous Commercial Ships

By Commander David Dubay, USCG

The world will never see fully autonomous transoceanic commercial cargo ships. In fact, autonomous vessels are likely to operate in only very limited situations. In recent years, the prospect of fully autonomous vessels has become a hot topic for commercial shipping. The same fast-paced advances in technology that have led to projects to automate vehicles in every other sector of the transportation industry have also found their way to the shipping industry. Advances in camera technology, sensors, electromechanical actuators, and satellite technology appear to promise a world in which ships will soon traverse the oceans without a human on board. The International Maritime Organization (IMO) and the Comité Maritime International (CMI) are already exploring how autonomous vessels would fit into the existing framework of international maritime law.

Yet, while it is laudable to plan for the future, autonomous vessels operated by computers and remote operators quite simply pose too many vulnerabilities and they likely will prove too expensive to replace today’s manned vessels. The professional merchant mariners who operate ships today are the crucial on-scene decision makers, repairmen, and physical security providers who make commercial shipping secure, efficient, and inexpensive. Once we get past the promises and hyperbole, the risk of collisions, legal liabilities, and environmental calamity will ensure that some critical number of humans will persist onboard ships. Advances in technology will continue to make shipping safer and more efficient, but they will not eventually replace the human masters and crews that serve on today’s commercial vessels.

Despite all the excitement, the benefits of autonomous ships are still very much up for debate. For shipping companies, a switch to autonomous vessels promises cost savings from not having to pay for a master and crew, and perhaps from increased safety. But scores of new operators and technicians would be required to make a system of autonomous vessels work. The equipment to automate a ship will be extremely expensive and would introduce many new potential points of failure into commercial shipping. Autonomous vessels may reduce the number of accidents caused by human negligence, however, the relative safety of autonomous vessels versus manned vessels is pure speculation at this point. Autonomous ships could potentially be more efficient if the space for the crew could be dedicated to additional cargo. But ships will still likely need to have systems and controls in place to allow them to be operated with human master and crew when there are system failures. Autonomous vessels may result in better working conditions overall in the shipping industry as they would eliminate the need to find workers to fill the many difficult and hazardous jobs at sea. But the elimination of merchant mariner jobs would be a tremendous financial blow to those workers in those jobs today.

Recent articles have proclaimed that autonomous vessels are here or just on the horizon and seem to take the adoption of autonomous vessels as a certainty. At an initial glance, the future of autonomous vessels appears very promising. For small vessels the technology that is needed to automate a vessel is here today and is available enough that even a hobbyist can build an autonomous vessel. In 2017, SEA CHARGER, a small solar powered and unmanned home-built boat successfully completed a trip from California to Hawaii using GPS and a satellite modem for guidance and connectivity. And companies in the shipping industry are already using technologies that could eventually be used to automate larger vessels. The newest vessel of the the Red and White Fleet, a San Francisco charter boat company, is a hybrid diesel electric with a 160 kilowatt lithium ion battery pack that provides enough power for the ship to do a one-hour Golden Gate cruise on battery power alone.

One present obstacle for automating larger vessels is battery technology. At the outset, today’s batteries simply do not have the energy density necessary to power larger commercial vessels. Higher capacity and more powerful electric batteries that are powerful enough to move larger ships will likely be developed in the future. However, current battery technology has limitations. Lithium ion batteries, the type used for automated vehicles and aircraft, can explode if overcharged and further, large lithium ion batteries need to be temperature controlled to work properly.

Even more challenging obstacles to the success of autonomous vessels will be the expense and complexity of designing such systems. The technical challenge of operating a large cargo ship autonomously on the open oceans for days or weeks at a time will require a command and control system that does not exist today and may be impractical to build. Seamanship and navigating a ship safely is a challenge with a full complement of crew members on board. Automated ships will require command centers, computers, advanced satellite communications systems, other electronic devices, remote operators, and other technicians. Autonomous vessels would save money by not having a crew, but shipping companies will in many cases be simply replacing merchant mariners with other workers, most likely more expensive technical workers, who will work in offices on land or will be on call to assist autonomous ships across the oceans. Shipping companies will likely need multiple redundant command centers to provide the robust level of connectivity required for the safe and secure operation of these ships.

All of this advanced technology will be very expensive and much of the expense will be the cost of designing and operating a system capable of providing the propulsion, navigation controls, and stopping power necessary to operate a ship continuously in the harsh ocean environment. Weather, wind, waves, fog, obstructions, marine mammals, salt water, weather, birds, other ships, sounds, and almost anything else imaginable is encountered out on the open ocean. An autonomous ship will require incredibly complex technology to withstand the chaos of the ocean environment and enable a ship to respond remotely to any incident or emergency. It is still an open question whether today’s controls and communications technologies are sufficiently robust and capable so as to be relied on for commercial shipping in place of a human crew.

The most serious concern regarding autonomous vessels is the one that will very likely keep them from ever being employed: the risk of exploitation by adversaries, hackers, terrorists, criminals, and other malign actors. Autonomous vessels’ dependence on the electromagnetic spectrum and cyberspace infrastructure coupled with the lack of any human on-scene responders will provide an opportunity for others to interfere with these ships and potentially use them as weapons or for profit. The challenge for system designers is that the characteristics or features that make an automated system feasible for commercial application, such as standardization, continuous communications, and periodic updates, also provide exploitable opportunities for bad actors. Autonomous commercial cargo vessels would provide too easy a target of opportunity for theft, misuse, interference, or worse.

Conclusion

Some reality must be injected into the debate over autonomous ships. It is a truism that electronic and mechanical systems will eventually fail. For vital applications where human lives are at risk such as for aircraft, system engineers design in wide tolerances, safeguards, and multiple levels of redundancy to ensure an adequate margin of safety. The challenge in designing autonomous vessels is building both a safe and secure system that will function effectively in all ocean and maritime conditions without human beings on board and one that is not capable of being exploited by bad actors. Such a system, even if possible to build, would likely be too expensive for companies to build and operate compared to human crew. As a result, autonomous vessels are extremely unlikely to displace the human network of maritime professionals that have always made the maritime transportation system safe and secure.

Unmanned Systems Week Wraps up on CIMSEC

By Dmitry Filipoff

Last week CIMSEC published articles submitted in response to our call for articles released in partnership with the Navy’s Unmanned Maritime Systems program office. Authors discussed how to experiment with unmanned systems, how unmanned systems can contribute to amphibious assaults and fleet air defense, among other operational and developmental questions. We thank the authors for their excellent contributions. 

Create an Unmanned Experimental Squadron and Learning System” by Dustin League and LCDR Daniel Justice

“…we propose that the Navy revisit history and revitalize the complex learning system it used to exploit an earlier set of new capabilities prior to World War II. Specifically, we call for the Navy to accelerating standing up a dedicated experimental squadron with the purpose of exploring advanced tactics for employing unmanned systems in a series of tactically challenging, objective-based exercises.”

Unmanned Units Need Tenders for Distributed Operations” by Griffin Cannon

“Looking to the past, the precedent of the Pacific War, in which fleet tenders provided engineering support to a mobile fleet, suggests a path forward. Basing a support and sustainment model for Unmanned Surface Vehicles (USVs) on 21st century tenders would both fulfill the unique support needs of USVs and help build the ability to fight and deter a war in the Pacific.”

Autonomous Pickets for Force Protection and Fleet Missile Defense” by 1st Lt. Walker D. Mills

“In all cases, the ability to form a protective perimeter of unmanned systems beyond the edge of the fleet would significantly boost survivability and increase options for the fleet commander by lowering risk. A flotilla of autonomous pickets, armed with effective CIWS and multi-spectrum missile countermeasures, can function as a powerful yet affordable force multiplier. Such a force would provide the Navy with an increased ability to operate and project power inside an anti-access, area-denial (A2/AD) network and help the fleet weather storms of missile salvos. “

Accelerating the Renaissance of the U.S. Navy’s Amphibious Assault Forces” by George Galdorisi

“The ship-to-shore movement of an expeditionary assault force was—and remains—the most hazardous mission for any navy.  The value of real-time ISR and IPB is difficult to overstate. It is this ability to sense the battlespace in real time that will spell the difference between victory and defeat. For this reason, it seems clear that the types of unmanned systems the Department of the Navy should acquire are those systems that directly support naval expeditionary forces that conduct forcible entry operations. “

Providing Secure Logistics for Amphibious Assault with Unmanned Surface Vehicles” by Neil Zerbe

“…the Navy would be better served by embracing the always successful “crawl, walk, run,” method and use commercial off-the-shelf technology to evolve an already proven logistics capability before committing to ambitious plans with unmanned surface ships that aren’t yet on the drawing boards. Far from distracting Navy officials from these more lofty ideas for using unmanned systems, demonstrating this capability in Navy-Marine Corps exercises would likely accelerate the Navy’s embrace of unmanned systems.”

The Case for Unmanned Surface Vehicles in Future Maritime Operations” by Wayne Prender

“While it is encouraging to see Navy plans to move quickly to bring initial Medium and Large USVs into the fleet, other unmanned platforms are equally ready for such an approach. Innovation is the key to shaping tomorrow’s Navy, and getting USVs of all shapes and sizes to the fleet for Sailors to try out is the best approach to achieving it.”
