In September 1999, NASA lost a $125 million Mars orbiter because a contracted engineering team used English units of measurement while NASA’s team used the metric system for a key spacecraft operation.[i] In everyday life we are forced to choose between differing formats with the same function. What was once VHS vs. Betamax became Blu-ray vs. HD DVD. A lack of component standardization can reduce the operational effectiveness of a system as shown by the NASA orbiter. More commonly, the end user may waste resources purchasing multiple components that serve the same purpose, as was the case for DVD players in the late 2000s. These same issues are occurring in the development, procurement, and operation of our unmanned systems. Over the last decade, the US military has amassed large numbers of unmanned systems composed of highly proprietary hardware and software components. However, future unmanned systems designed with interoperable hardware and software and constructed utilizing advanced manufacturing techniques will operate more effectively and efficiently than today’s platforms.

 

Advances in manufacturing techniques as well as efforts to standardize software and hardware development are being pursued in order to diminish the negative effects caused by proprietary components in unmanned systems. These new technologies focus on speed and customization, creating a new and evolving research, development, and production methodology. Modular designs increase the rate of production and upgrades while new manufacturing techniques enable rapid prototyping and fabrication on the front lines. Replacement parts can be stored digitally, produced on demand, and swapped between unmanned systems, reducing the system’s logistical footprint. This organic production capability will enable units to tailor manufacturing needs to match operational requirements. The resulting unmanned systems will operate with interchangeable payloads making them quick to adapt to a dynamic environment while common software will enable easier control of the vehicles and wider data dissemination.

 

Complementary Technologies

 

The concept of interoperable hardware and software is more formally referred to as open architecture (OA). DOD Directive 5000.1, “The Defense Acquisition System,” outlines the DOD’s goal to acquire systems that can be easily swapped between unmanned systems similar to the way different types of USB devices can be swapped out on a personal computer. [ii] This ranges from swapping sensor payloads between platforms to entire unmanned systems between services and countries.[iii] Establishing standards and creating policy for OA are the responsibilities of multiple organizations. For unmanned aerial systems (UASs), the Interoperability Integrated Product Team (I-IPT) drafts UAS System Interoperability Profiles (USIPs). Similarly, the Robotic Systems Joint Program Office (RS JPO) creates Interoperability Profiles (IOPs) to identify and define interoperability standards for unmanned ground systems. Several of the IOP standards have been adopted for unmanned maritime systems by the Naval Undersea Warfare Center.[iv]

 

Advances in manufacturing techniques complement and leverage the OA concept. In general, these techniques focus on converting a digital blueprint of a component into its physical form. The advantages of additive manufacturing, commonly known as 3D printing, have been recently publicized as well as potential military applications.[v],[vi],[vii],[viii] 3D printing creates the desired object in metal or plastic by converting liquid or powdered raw materials into a thin solid layer, forming a single layer at a time until the piece is completed. Less mature technologies include Printed Circuit Microelectromechanical Systems (PC-MEMS) uses 3D printing to create a flat object of rigid and flexible materials with special joints that are later activated turning the flat object into a three-dimensional object much like a children’s pop up book. [ix],[x] A final technique inspired by origami involves etching crease patterns into flat sheets of metal allowing them to be quickly folded and assembled into complex components. [xi]

 

Lifecycle Impacts

 

Production of future unmanned systems will be altered by these technologies beginning with the initial system requirements.[xii] Standard capability descriptors minimize the need for a single, large business to create and entire unmanned system. This will allow small businesses to focus research and development on a single capability that can be integrated into multiple platforms requiring that capability thereby increasing competition and innovation while reducing initial procurement costs.[xiii],[xiv] These unmanned systems will be easily upgradeable since payloads, sensors, and software are anticipated to evolve much faster than the base platforms.[xv] Open hardware and software ensures that upgrades can be designed knowing the component will function successfully across multiple platforms. Advanced manufacturing techniques will enhance the development of these upgrades by allowing companies to rapidly prototype system components for immediate testing and modification. Companies can digitally simulate their component to verify their design before mass producing a final version with more cost effective traditional manufacturing techniques. The final version can then be digitally distributed enabling the end user to quickly load the most recent version before production.

 

These technologies also have the potential to significantly impact supply chain management and maintenance procedures required for unmanned systems. Since components can be swapped across multiple platforms, it will no longer be necessary to maintain independent stocks of proprietary components unique to each platform. If a component can be created using organic advanced manufacturing techniques, only the digital blueprint and raw materials need to be available. While the strength of components created using additive manufacturing may not be enough for a permanent replacement, temporary spare parts can be created in a remote area without quick access to supplies or depot repair facilities while permanent replacements are delivered. This reduces the logistical footprint and maintenance costs by limiting the number of parts and raw materials required to be physically stored for each system.

 

Most importantly, these technologies will produce unmanned systems with the operational flexibility necessary for the unknown conflicts of the future. Components ranging from power systems to sensor payloads can be quickly and easily swapped between platforms of varying vendors, selected to fit the mission requirements and replaced as the situation develops.[xvi]Standardizing the sensor’s data transmission format and metadata will generate timely and accurate data that is more easily accessed and navigated by all interested parties.[xvii] An early example of these advancements, the Army’s One System Remote Video Terminal, allows the user to receive real time video footage from multiple platform types as well as control the sensor payload.[xviii],[xix] Digital libraries will close the gap between developer and user ensuring the most recent component design is manufactured or the latest software capability is downloaded and transferred across platforms.[xx] Standardized communications protocols between the platform and the controller will enable a single controller to operate different platforms, as recently demonstrated by the Office of Naval Research.[xxi] Further into the future, the operator may be able to control multiple unmanned systems across various domain simultaneously.[xxii],[xxiii] The ability to create heterogeneous “swarms” of unmanned systems with varying sensor suites in different physical operating environments will give the commander the flexibility to quickly configure and re-configure the unmanned system support throughout the duration of the operation.

 

New Technologies Create New Vulnerabilities

 

As these technologies are implemented, it is important to keep in mind their unique limitations and vulnerabilities. The stringent qualification process for military components, especially those with the potential to harm someone, is often described a key limitation to the implementation of modular components.[xxiv] However, without people on board, unmanned systems have lower safety standards making it easier to implement modular components in final designs. Compared to traditional methods, additive manufacturing is slow and produces parts limited in size. The materials have limited strength and can be 50 to 100 times more expensive than materials used in traditional methods.[xxv] While future development will decrease prices and increase material strength, traditional manufacturing techniques will remain more cost effective means of producing high volume items into the near future. Additionally, open designs and digital storage can create vulnerabilities that may be exploited if not properly secured. Militants in Iraq purportedly viewed live video feeds from UASs using cheap commercial software while Chinese cyberspies allegedly gained access to many of the US’s advanced weapons systems designs.[xxvi],[xxvii] Further, digital blueprints of parts have the potential to be modified by nefarious actors to create counterfeit or falsified parts.[xxviii] As the price of manufacturing equipment quickly drops, anyone can create the products when given access to the digital copies.[xxix]

 

Future technological innovations have the ability to modify traditional supply methodologies allowing the end user to manufacture parts on demand for use in a variety of unmanned systems. Proprietary hardware and software can be minimized, resulting in unmanned systems with smaller logistical footprints condensing vulnerable supply chains while reducing overall system cost. These benefits are tempered by the unique vulnerabilities that arise when standardizing and digitizing unmanned system designs. Despite these potential vulnerabilities, the ability to equip a force with increased capability while reducing costs and logistical requirements is indispensable. While the locations of the next conflicts will remain hard to predict, unmanned systems able to complete a variety of missions in remote areas with limited logistical support will become an operational necessity.

Embracing Pandora’s Box – Unleash the Drone Exports

1 Comment
Drones are a rapidly expanding market in the international arms trade. Intelligence, surveillance, and reconnaissance (ISR) is crucial for operating in the modern battlespace and drones are the best way to get that information by maximizing loiter and removing risk to a pilot. Demand is high and supply is low; only a few countries produce the class of drones that are most in demand. This would seem a perfect market for the United States to sell its wares and dominate the exchange but it is currently hamstrung by policies which discourage their export. The hesitation to export the technology, while done for good reasons like maintaining United States’ technological advantage and protecting a powerful capability from exploitation by foreign agents, is misguided; without the powerful network of communications satellites and Global Information Grid (GIG), the drones themselves are little more than complex model airplanes with good cameras. The United States’ efforts are akin to closing Pandora’s Box because of imagined evils without recognizing the good that remains left trapped inside.
 
Exporting drones is a good thing for the United States. First, it promulgates a capability we want our allies and partners to possess. For years, British and Italian MQ-9 Reapers have patrolled the skies over Afghanistan, bringing the twin benefit of additional ISR to the battlefield and eliminating the need for American assets to cover those units. In addition, the British have armed MQ-9s that provide additional strike assets to coalition operations. The United States only stands to gain by exporting more of these assets.
 
Dominating the supply of drones brings the United States leverage it would not otherwise have. Just as with other aviation assets, drones need a steady stream of supplies to be viable. If the country that operates those assets uses them for purposes that are against the United States’ interests, the United States can then press forward with sanctions and cut off supply of crucial parts needed to keep the assets operational. In a world fraught with fault lines and shifting loyalties, leverage matters.
 
There are a couple arguments in favor of restricting drone exports. The first is wishful thinking. The argument holds that by restricting the sale of to foreign clients, we will deny them drone capabilities, particularly their ability to conduct strike missions. The problem is that Pandora’s Box is already open. Even though there are few suppliers of in the field right now, there are many others that are about to enter the market. A joint European consortium, led by France, is developing the nEUROn. Britain is developing the Taranis. China is aggressively marketing the ASN-209 at international airshows. Chris Rawley highlighted Singapore’s entry into the market in his recent article (https://cimsec.org/unmanned-systems-distributed-operations-one-many/). Even Turkey is developing the Anka. If there are lots of suppliers, the United States will no longer have its privileged negotiating position and will need to make more available to encourage use of its platforms. This means expanding the list of what is exportable and seriously considering exporting armed assets.

The other argument against exporting drones is out of fantasy (as Dave Blair elucidates in his excellent article here: https://cimsec.org/remote-aviation-technology-actually-talking/). The argument goes that the United States should not export drones because they are a revolutionary capability that would unfairly strengthen possible adversaries. This, too, falls short. The aircraft themselves are only a small portion of the equation and what makes them great tools of war. The real strength of drones is their ability to conduct global operations which requires the United States’ network of satellite communications to operate in a distributed manner. Without that network, the drones are nothing more than a more capable model airplane that linger longer than a fighter or helicopter.
 
The story of Pandora’s Box ends with Pandora desperately shutting the lid in a vain attempt to keep bad things from entering the world. Unfortunately for Pandora, it was too late; the damage was done. The only effect that she reaped by keeping the box closed was to leave hope penned inside. While the United States did not unleash the desire for countries to acquire drones, it certainly is achieving the same effect as Pandora by ignoring the world in which it lives. The better course of action is to recognize what drones are truly capable of on their own and embrace an export mindset.

Drones and the Human-War Relationship

Leave a comment

Robots fascinate humans. They abound in movies: Star Wars, the Terminator, the Matrix. They are a foil for the human condition. In rosy predictions they are like Star Trek’s Data, “perfect” in strength and intellect yet void of emotion. In dystopian futures, killer robots are poetic justice. Created by humanity, robots attempt to annihilate their creators. If told killer robots exist in the U.S. arsenal, most Americans would probably think of “drones.” The name sounds robotic; it implies automaton behavior. Drones lack an onboard crew, and just like robots, drones fascinate Americans. In one important way, however, drones are not robots: they are flown by humans; they are just flown by remote control, but this creates a problem all of its own.

The Armed Forces are not even sure how to deal with drone pilots. The pilots play a pivotal role in combat operations. They make life or death decisions. They press the button to fire missiles. They probably engage in more “lethal actions” than other air units at present. Nevertheless, most fellow service members and the public at large do not think drone pilots hold “combat” jobs. Our system cannot square the responsibilities these service members have with the lack of surrounding danger.

The presence of danger has always been a defining characteristic of war and particularly in the way civilians see the armed forces. While Americans generally no longer glorify the taking of spoils, we do glorify success in the face of adversity and particularly danger. American society regularly “thanks” service members with things like recognition at sporting events and military discounts. These types of recognition purposely avoid mention of the policies those being thanked implement: “Support the Troops, whether you support the war or not.” But that approach only works if service members are seen to represent honorable values like service and sacrifice. Take away the danger and something of those values seems to disappear too.

130424-F-NL936-999.JPGOf course, some soldiers have always been relatively safe, performing jobs in the rear areas. Most civilians do not see past the uniform, but service members know who is actually at the front (though ironically the insurgencies of the past 40 years have eroded the difference). For those actually pulling the trigger, danger was always at least reciprocal if not near. While an artilleryman might not have been within rifle range of the enemy, he was in range of the enemy’s artillery.  Even ballistic missile crews in the United States were held at risk by their Soviet counterparts during the Cold War.

Drone pilots seem different because there is no reciprocity, but even that does not quite make drone pilots unique. The U.S. government has long looked to reduce danger to service members. Drones are only the latest idea. As the old Army saying goes “Why send a man if you can send a bullet?” The Navy has fully embraced this idea. The ships that launch manned aircraft and Tomahawk cruise missiles (a true killer robot) from the Mediterranean are in no more danger today than if they were training off the coast of California or Virginia. The closest most shipboard sailors have come to fighting in the last 10 years is pressing a button and then rushing to the TV in hopes that CNN will cover the resulting explosions. The Navy still uses the Iranian mine-laying operations in the late 1980s to justify for “imminent danger” pay for crews. If the Navy has not faced the same challenges as the drone community it is principally because distance from American shores obscures what is going on. A similar lack of reciprocity exists for most air and even some ground forces, both masked by distance. Indeed, this lack of reciprocity in many aspects of warfare is inherent to the asymmetric wars in which the United States has engaged.

Wars of the future may ameliorate this problem in some situations but will likely exacerbate in most. As the United States again faces the potential of great power conflict, the likelihood it will face an adversary with advanced air, land, and sear forces greatly increases. Nonetheless, a key lesson of the past decades has been that those who fight the United States on its own terms lose. This situation is likely to remain unchanged for several decades. Thus even great power competitors will seek to field forces that challenge American forces asymmetrically which made lead to situations lacking reciprocity even as the United States continues to develop technology to further protect its service members from danger.

Drones illuminate a problem which has already existed and will only grow in the future: In a society that professes not to value military spoils, how does the relationship with the armed forces change as service members become increasingly removed from danger?

Long-range weapons like artillery, naval gunfire, or close air support in a combined arms environment may suggest an answer. The Marine Corps has best developed this idea. Every Marine who is not primarily a rifleman understands his or her purpose is to support rifleman. For the naval gunnery liaison officer, his or her job directing the shore bombardment in support of forces ashore becomes more important because that officer operates from the relative safety of the ship but his or her actions mean life or death for forces ashore. At their best, these units draw their identity from the support and protection they provide to those in the greatest danger, and those in danger would never deny the importance of that support when well executed.

Without a doubt, danger will never disappear, nor should we reduce efforts to lessen it, but we must begin to think about a how the armed forces will relate to society as fewer service members go in harm’s way. While drones may not actually be robots, in one at least one way their arrival seems to have played a similar role: Drones have highlighted an all too human problem about how people relate to war.

A New Kind of Drone War: UCAV vs UCLASS

Leave a comment

This article was originally posted by with our partners at the Australian Strategic Policy Institute (ASPI’s) The Strategist.

The Australian government recently approved the acquisition of a fleet of US Navy Triton surveillance drones to patrol our oceans. Australia has mostly used Israeli drones to date, such as the Herons in Afghanistan. So as we dip our toes into the American UAV market, it’s worth taking note of a recent development that might be threatening US primacy in this area.

While the Predator and Reaper laid the groundwork for the use of armed drones in warfare, a question remains about the survivability of the technology against modern air defences. Developing a stealthy long-range drone with a decent weapons payload that could go beyond missions in Yemen and Pakistan appeared to be the next order of business for the US, especially in the future Asia-Pacific theatre. Projects like the demonstrator X-47B unmanned combat air vehicle (UCAV) have shown promise in achieving those missions. But for now the US Navy has decided to go for an unmanned carrier-launched surveillance and strike (UCLASS) system that won’t have the stealth or payload to penetrate air defences.

The UCLASS system will be designed to provide Navy carriers with long-range surveillance and strike capabilities to target terrorists in much the same way as the Air Force’s drones are currently doing from bases around the world. The capacity to carry out those missions without relying on foreign bases is driving this decision, along with lower costs. But the UCLASS system will only operate over states that have limited air defences (because of UCLASS vulnerability) or have provided the US permission to conduct strikes. Al-Qaeda affiliates are on the rise in Syria, where the Assad regime is both hostile toward the US and has the capability to deny drones. This raises the question of how many states will fit this category.

Consequently, at a program cost of US$3.7 billion, the UCLASS won’t provide the degree of innovation the 2014 Quadrennial Defense Review (PDF) advocated. This would be money better spent on more research and development (R&D) into a UCAV, which could potentially have greater impact in the future strategic environment. Moreover, the UCLASS would be mostly redundant in Asia, the most strategically important future region for the US. UCAVs, on the other hand, could have an impact in, for example, a future conflict with China. According to Mark Gunzinger and Bryan Clark at the Center for Strategic and Budgetary Assessments (CSBA), a UCAV with a range of 2,000kms, broadband stealth, a payload to rival the manned F-35C combat aircraft, and a capacity for aerial refuelling, is achievable. Developing a UCAV that’s survivable is no mean feat, but the US has a good start in terms of support systems and personnel established over the past few decades.

UCAVs would be capable of rapid deployment from carriers, which could stay out of the range of anti-access threats. A persistent surveillance capability that could also strike vital command and control and air defence sites if required could open the way for follow-on operations by manned aircraft. A UCAV would form a valuable part of the US deep strike suite, a key feature of AirSea Battle (PDF). And while losing platforms is never good, drastically reducing risk to personnel is a major incentive, especially early on in a conflict.

China’s an active player in drone development, and the PLA’s R&D investments are another good reason for the US to think carefully about holding off on UCAV development. China’s Sharp Sword UCAV, which was flight-tested in 2013, shows the PLA’s commitment to creating a mix of manned and unmanned combat aircraft. The growing Chinese defence budget (with a reported increase of a 12% this year) could lead to rapid advances in this area.

Funding the UCAV is the big question considering the cuts to the US defence budget; its price-tag would be heftier than the UCLASS. Proponents of the UCAV such as CSBA and the Center for New American Security (CNAS) (PDF), argue that the money could come from decommissioning two (or possibly more) carrier groups. Budget pressures have already seen cuts and deferrals to the carrier force and it would be a big step to cut two more. What’s important in these perspectives, however, is that the UCAV’s stand-off capacity and flexibility could make each carrier more effective. As Michael O’Hanlon pointed out on The Strategist last month, capability should be the metric of adequacy, not dollars or hull numbers.

The UCLASS could be redundant by the time it enters service in 2020, even in the targeted killing missions it’s designed to carry-out. A UCAV, on the other hand, would stretch the envelope in relation to advanced technologies, which would contribute to sustaining US strategic advantage. It would enhance a carrier group’s capability to respond to anti-access threats and it could also be versatile enough to respond to terror threats globally. Unmanned systems show no signs of fading into the background, and even in a tight fiscal environment represent a potentially high payoff for R&D funds.
