National Defense > Blog > Posts > Not-So-Secret Weapon in the War on Drugs: Sensors That Can Infiltrate Jungles
|
4/27/2010 What will it take to win the war on drugs? Apparently, foliage penetrating radar.
The U.S. military and law-enforcement agencies for years have been chasing drug and arms traffickers in Latin America, with limited success. With more surveillance aircraft now deployed over the Caribbean, it is becoming easier to catch sight of smugglers at sea, even when they travel in stealthy submarine-like semisubmersibles.
But the jungle has so far been rather impenetrable to most U.S. sensors. Drug cartel operatives and builders of semisubmersibles can safely hide in double- and triple-canopy jungle, and there are not many spying devices that can spot them, says Air Force Gen. Douglas Fraser, head of U.S. Southern Command.
SouthCom covers a region of 16 million square miles, stretching south of Miami to Antarctica. It encompasses 45 countries and territories in Central and South America and the Caribbean.
In some parts of Colombia, for instance, cartels take advantage of the thick jungle cover and construct their semisubmersibles practically under the noses of the authorities.
“You can be 10 feet away from where someone is building a submersible and never see it,” Fraser tells reporters at a breakfast meeting this morning in Washington, D.C.
U.S officials have found trails, cocaine labs and hideouts, all underneath the canopies, says Fraser. So far, one of the most successful weapons in the U.S. counterdrug arsenal has been the Army’s A-160 Hummingbird unmanned helicopter. The aircraft is equipped with a foliage penetrating radar that was designed by the Defense Advanced Research Projects Agency.
Over the past 20 years, the U.S. military has focused on finding the cocaine-laden semisubmersibles as they cross the Caribbean. SouthCom, working with local law-enforcement and military agencies, typically manages to intercept only about 25 percent of the cocaine that is smuggled through the Caribbean and eastern Pacific Ocean each year. Most of the drugs, about 80 percent, are transported on fast boats and semisubmersibles.
The U.S. counterdrug campaign would be more effective if the hard-to-detect semisubmersibles could be found before they go in the water, says Fraser. Illicit trafficking has to be looked at as an “enterprise,” he says. SouthCom officials are now focusing on how cartels obtain supplies, how they move cargo and how they finance their operations, he says. One of the harder tasks is to find where the semisubmersibles are being assembled, he says.
The vehicles have a low profile so they are barely seen above the water line. They are 60 to 70 feet long and carry four to 10 tons of cocaine, are powered by diesel motors with a range of up to 5,000 miles. The traffickers generally travel at night and lie low during the day. In 2008, SouthCom caught 76 semisubmersibles; but only 52 were intercepted in 2009. It is not clear whether the drop is indicative of fewer semisubmersibles in operation or if the traffickers are just managing to not get caught, says Fraser. “I don’t know whether that means the trend has fallen off in the use of these vessels, or they’ve changed their tactics and we just didn’t see as many as we did the year before,” he says. “They change tactics. … They’re well-financed.”| Edit in Browser | /_layouts/images/icxddoc.gif | /blog/_layouts/formserver.aspx?XsnLocation={ItemUrl}&OpenIn=Browser | 0x0 | 0x1 | FileType | xsn | 255 | | Edit in Browser | /_layouts/images/icxddoc.gif | /blog/_layouts/formserver.aspx?XmlLocation={ItemUrl}&OpenIn=Browser | 0x0 | 0x1 | ProgId | InfoPath.Document | 255 | | Edit in Browser | /_layouts/images/icxddoc.gif | /blog/_layouts/formserver.aspx?XmlLocation={ItemUrl}&OpenIn=Browser | 0x0 | 0x1 | ProgId | InfoPath.Document.2 | 255 | | Edit in Browser | /_layouts/images/icxddoc.gif | /blog/_layouts/formserver.aspx?XmlLocation={ItemUrl}&OpenIn=Browser | 0x0 | 0x1 | ProgId | InfoPath.Document.3 | 255 | | Edit in Browser | /_layouts/images/icxddoc.gif | /blog/_layouts/formserver.aspx?XmlLocation={ItemUrl}&OpenIn=Browser | 0x0 | 0x1 | ProgId | InfoPath.Document.4 | 255 | | View in Web Browser | /_layouts/images/ichtmxls.gif | /blog/_layouts/xlviewer.aspx?listguid={ListId}&itemid={ItemId}&DefaultItemOpen=1 | 0x0 | 0x1 | FileType | xlsx | 255 | | View in Web Browser | /_layouts/images/ichtmxls.gif | /blog/_layouts/xlviewer.aspx?listguid={ListId}&itemid={ItemId}&DefaultItemOpen=1 | 0x0 | 0x1 | FileType | xlsb | 255 | | Snapshot in Excel | /_layouts/images/ewr134.gif | /blog/_layouts/xlviewer.aspx?listguid={ListId}&itemid={ItemId}&Snapshot=1 | 0x0 | 0x1 | FileType | xlsx | 256 | | Snapshot in Excel | /_layouts/images/ewr134.gif | /blog/_layouts/xlviewer.aspx?listguid={ListId}&itemid={ItemId}&Snapshot=1 | 0x0 | 0x1 | FileType | xlsb | 256 |
