DARPA Wants To Seed the Ocean With Delayed-Action Robot Pods

coondoggie writes "This plan sounds a bit like a science fiction scenario where alien devices were planted in the ground thousands of years ago only to be awoken at some predetermined date to destroy the world. Only in this case it's the scientists at Defense Advanced Research Projects Agency who want to develop a system of submersible pods that could reside in the world's oceans (presumably not in anyone's territorial waters) and be activated for any number of applications days, months or even years later."

Re:Nice souvenirs

Exactly.

TFA says (glibly)

Almost half of the world's oceans are more than four kilometers deep. This provides considerable opportunity for cheap stealth. The vastness and depth make retrieval costs prohibitive.

This of course totally misses the point that you need only recover ONE, and reverse engineer that one to obtain control over the rest.

If a relatively unsophisticated enemy can surf our live drone video stream in Pakistan right off of our own satellites, what would prevent a state sponsored group from recovering one with ROVs. Once you have one, you could theoretically take over control of these pods, launching them all at once to expend themselves well ahead of some planned attack in a particular part of the world.

Being located outside on one's own territorial waters, there is probably amble justification under marine salvage laws and treaties for private parties to recover these and sell them to the highest bidder.

WTF DARPA?

[Anonymous Coward]

I don't get it.

http://www.benthos.com/undersea-acoustic-release-modem-SMART-SM75.asp

The article must be glossing over what makes this unique. Do they want a factor of 10 reduction in price? I've been working on the problem of cheap deep water electronics for nearly a decade so this is relevant to my interests(honestly who in the field of oceanography hasn't? Nobody wants to pay a ship to go un-fuck a $100 science project and mass production of gizmos is not the core competency of scientists in most cases).

DARPA is essentially throwing up their hands at the problem of locomotion and saying it's cheaper from an energy standpoint to just pepper the ocean with lots of sensors than to transport a single sensor over lots of territory pushing water out of the way of its course. "Sensors" is a pretty broad catch-all for payload and can vary in price significantly, impacting the truth of that assertion.

Changing batteries isn't cheap so disposable is desirable. Why not just embed a cell phone in a block of epoxy or polyurethane? It is cheaper to drop ballast than it is to displace 100ATM of water, so they might as well settle on a solenoid fired shear pin or electric door strike type mechanism. Syntactic foam and you can do the whole thing with a cheap prepaid, a pic processor, and a solar cell. Battery life scales with price so that is a matter of mission endurance priorities.

Re:WTF DARPA?

You're rambling. Cell phone in a block of epoxy? Are you friggin' serious? How long does a cell phone battery last? Do you know how far a cell phone signal travels from a tower? Underwater.

Re:WTF DARPA?

You are totally oblivious.

Cell phones are nothing but low cost & mass produced ARM development kits with WiFi adapters and cellular modems that have had the driver compatibilities hashed out by the manufacturer. The user interface is totally redundant in this application, but I'm sure your next line of questioning is "How are you going to use a touch screen through a block of epoxy!"

Use your imagination because I don't feel obligated to connect the dots for someone who thinks that pointing out cellular comms don't work underwater is anything but blatantly obvious. It's not like applications exist that would allow for the hands-free jack to interface with an acoustic modem.

Seeing as DARPAs intention is obviously to achieve force projection along the coast lines of 3rd world shit holes by deploying their surface vehicles and UAS from stealth buoys, maybe they can mesh network their way close enough to shore or their buddy with an Iridium that can call home for further instructions?

Re:WTF DARPA?

[RubberDogBone]

saying it's cheaper from an energy standpoint to just pepper the ocean with lots of sensors than to transport a single sensor over lots of territory

Well, yes. There are many scenarios where it would be very cost effective to monitor a large area with scattered smart sand grains, each equipped with enough sensors to do whatever and some method to report back. Toss out a few million of them and wait, then correlate the results being fed back. If some of the sand grains get trashed, oh well. You sent out lots of them. Some will survive.

In a sense, this kind of tracking is nothing but motion capture on a very different scale than putting dots on a bodysuit, but somewhat the same idea. By tracking the dots, you build a shape of the object under the dots.

Personally I think this is a great way to explore space if you have a lot of time for results to come back. Toss out a cloud of smart sand grains and let them scatter across the galaxy. Then just wait for reports to come back. You won't need big rockets. You will just need patience. The only problem is that it will take a lot of time. I am convinced space-exploring species have found better ways to do this and perhaps in time so will we.

Have you seen how our military operates?
The Army has hundreds of overseas bases that cost megabucks to build, operate, and staff... just to host an airport or signit or [other].
They have no problem "pre-staging" a hundred million dollars worth of hardware on the off chance it might be needed in some random corner of the world.

One of the problems with the Iraq and Afghanistan wars is that the military has more or less emptied its overseas stashes and is now much less capable of responding to new events.
The idea of just tossing sensors into the ocean fits perfectly with the military's desire to have assets everywhere that are available on short notice.

Re:WTF DARPA?

Well then it's a good thing we have about 20 missile subs and 50 or so fast attack subs, too. Some of which could, you know, escort our 70+ destroyers with advanced anti-submarine detection and rocket systems, till they can reach a target within the 40 mile range of their guns or VLS Tomahawks.

An attack sub won't do much if it can't find a target, and something that can destroy a carrier fleet can be well away from the action when the fireworks go off. To put it differently, the equivalent would be a WWI Luftwaffe "flying circus" versus modern-day fighter planes well equipped with the latest air to air equipment that can be well away from the action.

The US military seems to have changed. In the past, it was effective. Now, showerheads can't even be grounded to prevent electrocution of troops in theaters of combat.

Re:WTF DARPA?

[Anonymous Coward]

Photo-voltaic would be for recharging the cell phone battery between communication bursts. Real time clock could synchronize the power switch between sites using a low power MCU like an MSP430. If a photo-voltaic can't handle the pressure during the phase of the operation where the buoy is hanging out at the bottom of the ocean waiting for an HFM or LFM sweep, wave power using a free piston linear motor as a wave powered generator is always an option.

Describing the circuit to build this audio trigger as an analog computer is outside the scope of me running my mouth on slashdot but a magnesium air or aluminum air battery should be able to create the enormous energy density with minuscule specific power requirements to supervise the light switch on the real brains. There is nothing more beautiful to me than the thought of millions of used iPhone 3s hanging out in the Tongan gulf all having their screens light up like a wave across a football stadium because a submarine whispered in their buddies ear 1000 miles away.

So industrial military complex, please take my idea and run with it. Or don't. I hope you do, but I'll do it if I have to. If, I or someone else ever finish writing software for all of this then I'll attribute the idea to this series of slashdot posts and no-one will ever know the identity of the anonymous coward slashdot troll who described an implementation of the Persistent Littoral Undersea Surveillance Network (PLUSNet) that can be rapidly fielded for little cost and repaired as nodes fail without asking congress for more money.

DARPA wants the whole shebang in a single package but it is more practical for them to segment the two functionalities by building the infrastructure of low cost wave powered or solar powered comms buoys and then leveraging that infrastructure to reduce their total investment in pod radios per square kilometer of ocean.

What is missing for that infrastructure to be developed is an economic case where its capital outlay and total cost of ownership after maintaining it are not so large as to leave the coverage too small to be relied upon, which is the status quo. An entire international economy is casting a shadow back through time on to the surface of the ocean, and the only way to bring this ghost to fruition is to address the economic problems which preclude it's existence. As a result of the advent of Bitcoin & Litecoin, an embedded computer WiFi cell-site can spend two thirds of it's life charging capacitors or lithium cells in order to afford the bribe to it's neighboring cell sites to relay its traffic saying "I'm still here" so as to not fall off the routing tables. This toll on through-traffic creates the necessary redress to the bandwidth tragedy-of-the-commons to both incentivize entrepreneurs to salt the coast lines with the an ever encroaching field of communication cells, and also maintain them with updated equipment as FPGAs and 16 core processors make the old systems a cost-center. Seemingly, the inherent profit advantage of having the most efficient cell cites will spur network investment. In an organic bottom up grassroots way, that government subsidies to Verizon's fiber network never could.

The final problems of end-to-end encryption & exit nodes have been well-researched thanks to government authoritarianism squeezing the internet. "Survivor" style anti-competitive alliances will have to be mitigated to prevent the network from falling to tribalism. Trade has always taken precedence over feuds when the money is sufficiently good, so I doubt it would be profitable to turn away packets just to fuck over a competing station's owner.

Another concern is jamming stations equivalent to government demanding a cut of the transactions as extortion. Traffic can be routed around these stations based on a networking algorithm that pursues least cost. signal strength, and throughput as deciding metrics. Nobody will bother with such obnoxious behavior early on simply because it is easier to shoot someone maintaining these buoys i

No, of course. I'm just trying to visualize the physical setup. Right now, I'm thinking a little box with business end of things laying on the bottom of the ocean (or close to it), tethered to a micro-bouy with a solar cell on it. Or does enough sun make it to the bottom of the (relatively shallow, since it's near the coast) sea?

Re:WTF DARPA?

[icebike]

Static Sensors is not the principal focus here. The navy has been using sonobuoys for decades, and yes they do just pepper the ocean with them.

The payload of these pods would have active components, Waterborn or Airborn (drone or balloon) that could be triggered into action to provide eyes and ears on events of interest without having to wait till a carrier with drone capabilities arrived on scene. They are specifically talking about unarmed pods with surveillance payloads that lurk on the ocean floor, perhaps for decades, until remotely commanded to launch.

This is different than your typical sonobouy in that it has an active and mobile component once triggered, but lays dormant until that point, using nothing but a low power radio waiting for a specific signal.

 

Re:WTF DARPA?

[icebike]

Try reading TFA. (Yeah, I know).

They want something sitting on the ocean floor tethered to NOTHING. When it receives a signal, it becomes buoyant, rises to the surface and becomes active, and perhaps even launches an airborn observation platform, (probably balloon or short life drone).

  Until triggered, it is essentially inert, it has no connection with the surface, so a long life power source is needed to keep the radio listening. They are looking for the capability to handle multiple different types of payload, at least initially none of those payloads would be munitions. They want them cheap enough that they can be planted in reasonably large numbers and left there for as long as possible.

Re:WTF DARPA?

[Anonymous Coward]

Clearly I failed to communicate. Are a satellite's photo-voltaics supposed to work while on the launch platform?

The photo voltaics recharge the battery of your mesh node which is only activated once an extremely low power DTMF tone decoder equivalent toggles the accoustic modem to wake the fuck up and determine if it is time to drop ballast and surface. The solar cells or wave generators are for re-charging the buoy during its operation as a buoy.

The biggest flaw IMHO is that mesh networking as a means of calling home via shore based GSM infrastructure or a friendly centralized Iridium satellite phone, assumes that mesh networking isn't more prevalent than it is without cause, and that WiFi's low power has an acceptable coverage area to justify the cost of the acoustic modem. WiFi would probably be opportunistic at the surface with the acoustic modem being the only practical mode of comms the majority of the time.

Re:WTF DARPA?

[Anonymous Coward]

I think the fact that a full-on coastal assault is required to get our birds safely within shooting distance is an enormous cost-center which is driving our fundamentally futile attempts to detect submarines with boats. A vehicle which is being force to overwhelm their natural predators using herd animal tactics. Herd animal tactics force us to expend a disproportionate number of resources playing defense for no greater profit than antagonizing subs.

Yes, we can do it, but it is a band-aid on the fundamental problem that our ability to make the oceans safe for commerce and our diplomatic influence felt is through extraordinarily expensive & man power intensive craft. If every munition could arm itself and deliver itself within the same effective range for less money we have fewer lives at risk with reduced logistics concerns limiting our theaters of influence. Man power are a substitute for autonomy. At such time as our communications are resistant to electronic counter measures, and our munitions are inexpensive, mass produced, and precise with a long range strike capability, we can put our sailors on subs where they belong. Anywhere that GPS and Sat Comms can reach is easily done remotely for less money and with more domestic patience for extended engagements overseas.

This is all based on the premise that our foreign policy should be as aggressive as it is, and that we need to be able to accomplish these things. I am only suggesting how we can accomplish the same goals for less money & risk to human life.

Maybe a list of one-time pads kept securely in the DoD? I could definetely see value in being able to secure a coastline by sailing around dumping a load of smart mines armed with supercavitating torpedos and advanced sensors with the ability to tell friend from foe. Or even better, send a sub around an enemy's coastline and drop them invisibly, break in case of war. Instant blockade!

Re:Security

[Jesus_666]

I don't think your plan of "deploy them in case we might need them later" is a terribly good one. International law requires you to announce any sea minefields you create (and as far as I know it doesn't make an exception for "but we haven't armed the mines yet") so you'd immediately tip off the country in question, most likely resulting in the rest of the world wanting to know why you mined the waters of a country you're not even at war with. Of course the "not at war" status might be open to interpretation at that point.

If you don't disclose your minefield then you'd better hope that those mines are never discovered because setting up a minefield in foreign waters in violation of international law is going to go over even less well.

Whichever way you turn it, this looks like a PR timebomb. Given the fact that the USA's reputation is fairly bad as it is perhaps it might be wise to only deploy minefields when you can actually justify their presence (with a better justification than "this is in our country's interest").


Plus, depending on the country in question you might not be able to deploy these where divers can't get at them. The last thing you want is for Hostilecountristan to steal^W salvage your supercavitating torpedos and then publicly shame you in front of the UN.

Re:Security

Its not a mine, so you don't have to disclose them. There is no ordinance payload.

Re:Security

A one time pad is fine if your implementation is absolutely perfect. Can you be sure there are no vulnerabilities in the sub's software?

Given how important control of the ocean is, this could well be an overwhelming advantage.

Yes, especially when your own drone subs start ramming your ships because someone fooled their GPS, just like Iran did with your airborne drones. Unlike airborne drones your enemy could have decades to work on cracking your security while the subs sit idle.

Re:Security

My post is not about what the article talks about, it's a reply to its parent post (as evidenced by it being submitted as a reply and not a completely new post). That post talks about deploying "smart mines armed with supercavitating torpedos" and keeping them inactive so that they can just be brought online "in case of war" - essentially CAPTOR mines with a modified fuze and a beefed-up detection system.

In other terms there is an ordinance payload, the payload does explode and they are most assuredly mines.

A robotic intelligence-gathering module that lies inert at 4000 feet deep doing nothing until you need an aerial reconnaissance platform in some remote corner of the globe. At which time you trigger it remotely, if floats to the surface, launches a balloon or remotely piloted aircraft with satellite up-link capabilities.

Somehow I think that's reasonably novel.
