Russian drug sub
Pictured in the Bogotá, Colombia, warehouse where it was confiscated in 2000, this hundred-foot (30-meter) narco-sub was found surrounded with Russian-language design documents. It could have carried at least 150 tons of cocaine or heroin, according to Colombian national police. Based on recent advances seen in cocaine-sub technology, experts believe submarine engineers from developed nations are providing technological expertise. "Nobody, not even the cartels, is going to invest millions of dollars in a submarine unless they've got proven engineers on hand that know what they are doing," Braun said. "That’s just a reality of the situation."
