What is coming down the pipe in naval and maritime technology?

Thinking Weapons are Closer Than We Think

This piece also at USNI News.

The Defense Advanced Research Projects Agency (DARPA) has constructed a neuromorphic device—the functioning structure of a mammalian brain—out of artificial materials. DARPA’s project, SyNAPSE (Systems of Neuromorphic Adaptive Plastic Scalable Electronics) signals a new level for biomimicry in engineering. The project team included IBM, HRL, and their subcontracted universities.

Biomimicry is not new. The most recent example is the undulating “robojelly” developed by the Universirty of Texas at Dallas and Virginia Tech. This new drone swims through the sea like a jellyfish, collecting energy from the oxygen in the water, as does any breathing organism. There is also the graceful Pesto SmartBird, an aerial drone that mimics the shape and physical flight of birds. A knockoff was found crashed in Pakistan. If not the shape, at least the actions are often mimicked, as shown by UPenn’s quadrotors being programmed to use crane claws like predatory birds rather than construction cranes. However, these examples of biomimicry only cover the external actions of an animal. SyNAPSE goes deeper, building a synthetic version of the mind that develops these actions.

In the quest for autonomous machines, the suggestions have been either-or: machines programmed to be like brains or the integration of biological processors to provide that processing flexibility. DARPA has found the “middle path” in constructing a series of synthetic synapses out of nano-scale wire. This takes the physical form of those biological processors and constructs them from the base material of conventional computers. According to James Gimzewski at UCLA, the device manages information through a method of self-organization, a key trait of autonomous action and learning, “Rather than move information from memory to processor, like conventional computers, this device processes information in a totally new way.” Moving past the surface mimicking of physical shape and function, SyNAPSE will mimic living organisms’ basic way of processing information.

However, as the possibility for real autonomy approaches, the legal challenge becomes more urgent. An article in Defense News summarizes the catalogue of problems quite well, from accidental breaches of airspace/territorial waters, to breaches in navigational rules, to accidental deaths all caused by machines not having a direct operator to hold responsible. However, as the director of naval intelligence Vice Admiral Kendall Card noted, “Unmanned systems are not a luxury; they are absolutely imperative to the future of our Navy.” Like the CIA’s armed predator program, someone will eventually open Pandora’s box and take responsibility for their new machines to gain the operational edge. DARPA’s SyNAPSE project is that next step toward an autonomous reality.

Lasers: Not So Fast

She blinded me with science: the LaWS installed on the USS DEWEY.

We may not have servant robots or flying cars, but it America is finally ready to deploy functional lasers. Next year, the USS PONCE will receive the military’s first field-ready Laser Weapon System (LaWS).  The navy, and nation, are justifiably excited to finally embrace military laser technology. However, it is important for us to realize the tactical and technological limitations of our new system before rushing too quickly to rely on them too often. Lasers still face great challenges from the weather, ability to detect hits, and power demands.

Red Sky in Morning:  

Lasers are nothing more than light: deadly, deadly light. Like all light, lasers as at the mercy of the atmospheric conditions they encounter. In particular, lasers are at the mercy of refraction and scattering. Refraction changes the angle that occurs as light moves through an atmosphere of varying density and makeup. As lasers are designed for longer ranges, or short range lasers encounter areas of differing conditions, the trajectory will change. This could pose challenges as targets move through areas of varying range and atmospheric density over long ranges.

Fog and house music, LaWS’ greatest enemy.

Laser light weakens over distance. Navigation types know this as “nominal range,” the range at which light can be seen in perfect conditions. A military laser’s effective destructive range is shorter, but the concepts are the same. “Luminous range” is the actual range of light due to atmospheric conditions. That range can be shortened by scattering caused by atmospheric conditions or precipitation. Lasers will be affected by such conditions as well, their effectiveness ranges shrinking in fog, rain, snow, etc… Depending how far the navy is willing to rely on laser technology, this could pose significant challenges to a fleet more beholden to the weather than before.

Eyes on Target:

Unlike kinetic rounds, lasers cannot be tracked en route to their target. An SM-2 explosion can be detected, the 76MM’s MK 98 tracks each splash and can be corrected by operators, and the CIWS system tracks each CIWS round for automatic ballistic correction. The refraction and scattering effects, combined with the time needed for LaWS to be effective, make judging effectiveness particularly important. The laser is not powerful enough to cause immediate destruction of target detectable by radar. If atmospheric interference prevents an IR tracker from detecting the laser heat signature on target, there is no way to verify trajectory and correct. This imposes, at times, a dangerous “wait and see” aspect to the use of LaWS. If a ship is engaging multiple C-802’s, and a LaWS has (hypothetically) range of 6nm, 37 seconds is not a long time for a ship to worry if its measures are effective.

Not Enough Potatoes in the World:

carrier
Enough power for a small city… or an array of space-age weaponry.

Missiles and guns come with the kinetic energy stored either in fuel or a charge; 100% of a laser’s power is drawn from the ship’s power supply. This means greater demands from the ship’s grid, as well as a greater scope of variation on grid demand as a laser powers up and down. This pumping of massive demand could cause problems for EOOW’s trying to maintain plant stability. Lasers will naturally require either vast changes in plant layout to support greater power production, or a collection of either batteries or capacitors to act as a buffer for the fluctuations in power demands. There is also the possibility of adding nuclear-powered defensive laser batteries to our mostly defenseless carriers, especially if they were allowed to increase their power output. What some are starting to call the “most expensive fleet auxiliary” will gain a invaluable punch for self-defense and defense of ships in company. For lasers to be effective, the projected power “magazine depth” under real combat conditions will need to be determined and supported.

Proper Room Clearance:

Pirates: When “arrrr” becomes “ahhhh!”

As Peter A. Morrision, program officer for ONR’s Sold-State Laser Technology Maturation Program has said, “the future is here.” Before calling the, “all clear,” on this future, the navy should properly clear the room. Laser technology has amazing cost savings and lethal possibilities, but still has serious weaknesses in weather susceptibility, verification of hits, and power demands that need solving. Other shadowy possibilities exist, such as enemies employing laser-reflective coatings that would require lasers to change wavelength to increase effectiveness. As the technology stands now, it is a worthy display of American technological supremacy that saves money on CIWS rounds and SM-2’s for limited instances. For the technology to truly carry the battles, it must be far more powerful and far better supported by ship-board systems.

Surviving the Invisible Commons

This article originally featured at the USNI Blog

In his piece, “Imminent Domain,” ADM Greenert suggests that the EM and Cyber spectrums need now be considered a stand-alone domain of conflict. Respectfully, we’re already there. The electronic environment, wired and unwired, is an obsession for defense planners. In CYBERCOM, the EM-Cyber spectrum practically has its own unified command. The navy’s component of CYBERCOM, the “10th Fleet,” in name harkens back to ADM Greenert’s example of the rise of sub-surface warfare. From the military’s fears over an assassin’s mace style EMP attack to the public’s obsession in movies like Live Free, Die Hard and games like Black Ops 2, the awareness is more than there. While we may have recognized this new environment, ADM Greenert is right in that we have not taken this challenge to heart.  If forces are going to operate as if the EM-Cyber spectrum is a domain of warfare, they must act as they would in the physical battlefield on the tactical level, not just the strategic: take cover, stay organized, and interrupt the enemy’s OODA loop.

 

TAKE COVER

 

In a battlefield, soldiers take cover to avoid detection and enemy fire. In the EM-cyber realm, we’ve made a habit of unnecessarily exposing ourselves to vulnerability. The US Navy has created an entire web of centralized databases that require not just mere control of the EM environment, but also a stability that often doesn’t exist at sea.

The Ordnance Information System-Retail (OIS-R) is the perfect example of unnecessary exposure to EM spectrum weakness. The system, designed to manage all ordnance administration, accounting, and inventory, requires a command to sign in to a shore-side database requiring uninterrupted connection through a Java interface. To access a ship’s ordnance data, one MUST have a functional internet connection either hard-wired or satellite. If account problems exist, troubleshooting must be done through other wireless means (phone, email, etc…) with land-based facilities. Each step requires a series of exposures to a very particular type of EM-Cyber connection to operate effectively.

The old system, Retail Ordnance Logistics Management System (ROLMS) was a stand-alone database that would update parallel shore-side databases through message traffic. The old system, while potentially harder for a single entity to manage, didn’t open the whole system to multiple weaknesses by environmental interference, enemy interference both kinetic and cyber, and equipment errors shore-side that a ship cannot trouble-shoot. It might be easier to keep all your ordnance (admin) in a huge pile, but to require warfighters to make a run through the open plains of TRON to get it is not a good idea.

 

STAY ORGANIZED

 

The drive to create centralized databases is often driven by a lack of organization on the part of the end-user. Properly organized supplies (data) minimize loss and the need to reach back into the logistical chain for material already packed. If the networks on ships are any indication, the average sailor enters the EM battlefield with absolutely no organization whatsoever. Sign in to a ship’s NIPR network and one will likely find  decade old files, repeated, in over a dozen similarly named folders: Operations Department, Ops, Operations, Ops Dept, OS1’s Folder, etc… Perhaps, those folders will have subfolders of the same name down 20 deep in series. Poor organization leads to inefficiency; inefficiency requires time, bandwidth, and exposure that should go towards the survival of the force and the success of operations. Ships need to treat their networks as they do their home desktops, organizing their material in a sensible way and deleting wrong, obsolete, or useless files.

Organization becomes the key to minimizing the need to go off-ship: well organized tech pubs, updated instructions in intuitive places, and personnel willing to spend the minute to search . A badly organized NIPR network is a reflection of how the navy treats the rest of its data: sloppily. We have seventeen sources pinging a ship for the same information that is held in 8 PowerPoint trackers, 2 messages, at least one call over the voice circuits, and 30 emails. Today, we expect every sailor to be at least an LS1 of the data-GSK, without giving them the tools or support to be so. One could drastically decrease the need to go off-ship for information by teaching sailors how to do a proper “ctrl-f” search or assigning an IT2 to deleting the ¾ of the network dedicated to obsolete files, animated .gifs, and 12 years of sea-and-anchor PowerPoints. Better training must exist not only in how to use data and of what kind, but how to properly disseminate/find it as well.

The battlefield equivalent of how we treat our data is sending soldiers into combat with a dozen different weapons from over the past century, but hiding them, their magazines, and their ammunition randomly throughout the base in mis-labeled boxes.  Like a poorly organized supply system, perceived “lost items” that are merely hidden end up wasting bandwidth on downloads, emails, and voice traffic as sailors work to solve the problems whose answers are merely in the 20th sub-folder down or in the inbox of the department head who doesn’t read his email. We must worry almost as much about the organization of our data as we do our organization of physical objects.

 

DOMINATE THE OODA LOOP

 

Survival often depends on an ability to use the enemy’s expectations of your methods against them. Some have suggested the navy embrace a wider range of bandwidths for communication; while true, more drastic measures are necessary to navigate the EM-cyber commons. In 2002, LtGen Paul Van Riper became famous for sinking the American fleet in a day during the Millennium Challenge exercise; he did so by veiling his intentions in a variety of wireless communications. We assume wireless to mean the transfer of data through the air via radio signals, but lights, hand signals, motorcycle couriers, and the like are all equally wireless.  These paleo-wireless concepts are just what we need for flexibility and security in the EM environment.

Combot vulnerabilities to wireless hacks are of particular concern to warfighters. Data connections to operators or potential connections between combots and ships serve as a way for enemies to detect, destroy, or even hijack our assets.  While autonomy is the first step in solving the vulnerability of operator connections, combots in the future must work as communicating teams. Fewer opportunities should be provided for subversion by cutting the long link back to the operator while maintaining the versatility of a small internally-communicating team. However, data communication between combots could still be vulnerable. Therefore, combots must learn from LtGen Van Riper and move to the wireless communications of the past. Just as ships at sea communicate by flags and lights when running silent or soldiers might whisper or motion to one another before breaching a doorway, combots can communicate via light, movement, or sound.

Unlike a tired Junior Officer of the Deck with a NATO code-book propped open, computers can almost instantly process simple data. If given the capability, a series of blinking lights, sounds, or even informative light data-transmissions  could allow combots of the future to coordinate their actions in the battlefield without significantly revealing their position. Combots would be able to detect and recognize the originator of signals, duly ignoring signals not coming from the combot group. With the speed and variation of their communications, compressed as allowed by their processing power, combots can move through the streets and skies with little more disruption than a cricket, lightening bug, or light breeze. High- and low-pitch sounds and infrared light would allow for communications undetectable to the average soldier or an enemy EW platform.

One must also accelerate faster than the enemy’s OODA loop can process. In the cyber realm, the enemy is often software long-ago released by its human creators. Like the missile warfare that inspired AEGIS, cyber warfare is both too vast and too fast for human reaction. Capital investment would concentrate more money in autonomous and innovative defensive programs: 10th Fleet’s AEGIS. Proactive patrol and detection can be done with greater advancements in adaptive self-modifying programs; programs that can learn or understand context are far more appropriate.  Recent developments in computing systems point to organic systems that could “live” in the systems they defend. Biological processors and organic computing allow for hardware that thinks and learns independently, potentially giving defensive networks the added advantage of an instinct and suspicion. Imagine the vast new horizons in the OODA loop of defensive cyber systems with hubs sporting the defensive animal instinct and the ability to re-wire their own hardwareQuantum computing also hovers over the horizon, with not only vast consequences for computing speed, but he whole cryptological offense-defense equation. The image painted is dramatic and far-off, but modest investment and staged introduction would serve as a better model than the dangerous possibility of a “human wave” mode of thinking. With fluid cyber-defense systems guarding more disciplined communicators, the US Navy can crush ambushes in the invisible commons.

 

ACTING LIKE IT

 

We will never be able to completely control the invisible commons; it is too heavily populated and easily influenced. Those conflicts held within vision are often confusing enough; the invisible becomes infinitely harder to master. However, if we minimize unnecessary exposure, organize ourselves well, and move with aggressive speed and unpredictability, our convoys of data will survive their long mili-second journey across the EM-cyber sea. ADM Greenert is right in saying the EM-Cyber world is a new field upon which battle must be done. However, while we may have realized it, we must start acting like it.

Evaluating China’s Anti-Ship Drone Swarms

The Project 2049 Institute recently released a report on People’s Republic of China (PRC) UAV advances, with a focus on how those capabilities could be used to threaten U.S. Navy carrier strike groups.  China’s expanding land- and sea-based UAV inventory runs the range from small tactical systems to medium-ranged Predator-class to unmanned combat air vehicles (UCAVs) still under development.  This anti-access/area denial capability, or A2/AD in naval parlance, represents just one of several layers of offensive systems the People’s Liberation Army (PLA) is developing to exercise naval hegemony in the Western Pacific. 
 
The report argues that “UAV systems may emerge as the critical enabler for PLA long range precision strike missions within a 3000 kilometer radius of Chinese shores.”  This 3000 km radius represents an area well into the so-called Second Island Chain, control of which is commonly recognized as a long-term strategic goal for the PLA.

China’s ASN-229A ISR and Strike UAV, just one of many friendly drones you’ll find in the Project 2049 report.

The report details Chinese strategists’ plans to use drones of swarms in a variety of ways to defeat opposing naval forces.  Decoy UAVs would draw fire and reduce the inventories of anti-aircraft missiles.  Electronic warfare (EW) UAVs would jam shipboard radars and anti-radition drones would attack them.  Reconnaissance drones could then cue anti-ship ballistic missiles (ASBMs) and armed UAVs in an attempt to overwhelm strike group defenses.

Defense against these swarms could take a number of forms.  First, dispersal of naval forces – over tens, hundreds, and thousands of kilometers – would prevent a drone swarm from doing too much harm to concentrated ship formations, also causing the PLA to prioritize its targets or disperse the swarm, limiting its effectiveness.  In an exchange against large numbers of low-cost drones, the engagement ratio, in both cost and number of weapons, is not favorable to air defense missiles such as those used by Japanese and U.S. Aegis ships.  A return to anti-aircraft cannon may be one option to reverse this asymmetry, though the introduction of directed energy weapons in the place of limited defensive missile inventories might be a better way to handle large numbers of incoming drones.  Interestingly, the U.S. Navy has announced it will deploy a prototype laser system, a previous version of which has been tested against UAVs, on USS Ponce in the Persian Gulf later this year.

It should also be noted that these systems would be susceptible to the same vulnerabilities cited by many observers of U.S. UAV operation: they can be jammed or spoofed, and the satellite or other communications links that control the drones can also be disrupted by various means. Finally, in the spirit of “it takes a network to defeat a network,” China would not have a monopoly on UAV development.  In time, PLA drone swarms would face large numbers of UAVs operated by other navies in the South China Sea.  Expect to see drones develop with air-to-air capabilities, defensive counter-measures, and programming to “sacrifice” themselves to protect surface fleets.
