Chinese Drones Will Use Genetic Algorithms to Learn to Hunt For Submarines
Popular Mechanics ^ | 2/29/2012 | Clay Dillow

China usually holds its military hand very close to the vest--that, or things “mysteriously” leak that it doesn’t (does) want the world to know about--so we’re left to wonder why the People’s Republic has decided to publish this in the journal Advanced Materials Research. Nonetheless, it’s pretty interesting. Chinese navy researchers have plans for a new submarine hunting scheme that uses ship-launched UAVs running genetic algorithms.

Genetic algorithms narrow down a range of possibilities to an optimal solution much the way evolution does (at least in a simplified sense)--by weeding out the weaker offspring and mating the best with the best to create stronger candidates. These algorithms would take into account things like fuel economy, potential air and sea threats, and oceanographic geography to zero in on the most likely places for submarines to be moving at a given time.

Working with dropped sonar buoys, the drones would then attempt to locate enemy subs in action. Just whose subs are Chinese hunting for, and in what waters do they expect to find them? Surely this revelation by the Chinese “underwater weaponry and chemical defense department” (yup, that’s a single department) at the naval academy at Dalian couldn’t have anything to do with Taiwan, the U.S., or the Pentagon’s renewed focus on the Pacific. More at New Scientist.

I worry more about their ability to detect thermal wakes.

China - The major reason why the US should not pullback on the development of weapons tactics and systems meant to defeat a near-peer opponent. China's frenetic rise, both militarily and economically, coupled with renewed vigor from Russia, are key reasons why the ability to fight against a technologically advanced opponent (as opposed to the usual set of adversaries faced over the last several decades who span from 'spray-n-pray Kalashnikov warriors for Allah' to 'monkeymodel MiG-29 with no BVR').

Considering that the only good fight is an unfair fight where the adversary has no real chance, the need to invest in technology and systems that provide an overwhelming advantage, as well as continually upgrading current systems and equipment, is a must. Which means that those who say only A-10s are needed (as someone said here in 2011) because they are so effective in Iraq/Afghanistan should remain cognisant that against a near-peer adversary they wouldn't be as hot.

Anyways, as the article wonders, who is the target for all the recent Chinese military expansion? Easy enough question to answer.

You can detect a “wake” by satellite.

They will also include the latest American technology thanks to the generosity
of the Obama regime passing on the most supersecret US Stealth Drone technology
to Iran - who is sharing this unexpected gift with China and Russia at this very moment.

The transfer of technology to the PRC from America continues at such a speed via so called “free trade” that AMERICA will become the near peer in this generation.

We are oblivious, brainwashed to not look at what “free trade” is doing to America.

The denial on the right, is frightening.

Otherwise logical conservatives simply refuse to think about the possibility, America very truly can be surpassed, exactly the way we are doing things.

“Free trade” is a way to defeat our own nation.

And then the drones will learn that it is the Chinese that “feed” them and then they’ll demand that they be allowed to sit in the hangar and be fed and and do nothing and then you have Democrat drones.

Why? It's because it is a missing link and they know if they publicize the 'problem' that some self-absorbed American engineer will go right to work on it and publish the answer somewhere on the internet.

The Chinks are going public with this so we will develope it and they can steal it.

My fear is that they either know they now have us technologically and that we can’t catch up, or they have developed the next “secret weapon”.

Look through history, the “secret weapon” or technology advance has always been the war winner. bronze, iron, horse shoes, bridle, cannon, armor, aircraft, nuclear weapons.

What is next? An ability to take out all of an enemies nukes? Or, antimatter weapons?

The anti-matter possibility you mentioned is very intriguing indeed. I’m afraid that the administration is deliberately giving up our nukes so the Chinese and Russians are getting more brazen by the minute now.

Nothing all that interesting, new or unusual about “Genetic” algorithms - I implemented this for an image processing class in 1997 and it wasn’t new then.

Its a sub heading of artificial intelligence.Every organism has a set of rules, a blueprint so to speak, describing how that organism is built up from the tiny building blocks of life.Genetic Algorithms are a way of solving problems by mimicking the same processes mother nature uses

Quantities measured in grams will be required to achieve destructive effect comparable with conventional nuclear weapons; one gram of antimatter annihilating with one gram of matter produces 180 terajoules, the equivalent of 42.96 kilotons of TNT .Unlike thermonuclear weaponry, positron weaponry would leave behind “no nuclear residue”, such as the nuclear fallout generated by the nuclear fission reactions which power nuclear weapons. Antimatter is expensive to produce though. The cost of a gram of the stuff is 2.5 million dollars and it would take 250 years to produce typical hydrogen bomb levels. But I love it.Fantastic idea.

They can if they have certain equipment on the satellite.Lasers, infrared and other detectors and synthetic aperture radar (SAR). Satellites might see subtle undersea disturbances caused by submarines, watch wave patterns on or beneath the sea surface, or detect subtle variations in ocean temperature.

National Reconnaissance Office operator of the US spy satellite fleet - is planning multiple satellite launches, and China must assume that one or more of these new US surveillance satellites will help support US Navy efforts to locate and track PLAN submarines

Don’t the nuclear reactors give off a heat signature that leaves a “heat wake” as the sub moves through the icey waters?

Detecting thermal radiation directly from the submarine at a
depth greater than a few meters would be very difficult if not impossible and submarines usually travel at much greater depths.You could detect it on the surface

maybe. I always remember how confident Rommel was that his communications with Germany were secure. Unfortunately for him, he put a little too much faith in his native technology and it cost him Africa. America puts too much faith in her technology and takes too much for granted with regards to enemy technology. We are notorious for underestimating enemy capabilitiers and over estimating our own and we never seem to learn. Do we know that out subs can’t be detected? Do we know that our communication is secure? Do we know that the F22 is truly stealthy?

There is one way to test our communications are secure is to change frequencies.Set up special “war time” frequencies,monitor the frequencies,monitor the satellite codes,check time intervals or set up a cryptographic system.

We have frequency hopping sincgars radios of course and we presume that they are secure. Maybe they are, maybe they aren’t. I think the system is old enough now that russian and/or Chinese intelligence agents have had time to thoroughly investigate the technology. Russia and China both have plenty of money and competent computer programmers these days.
