Apparently the Columbian drug cartels are building submarines as well:

Take for example the half-built submarine seized by the Columbian National Police last month in a warehouse outside Bogota. Not much in this business surprises me anymore, but this was something special. The submarine had a double hull with a displacement of 150 tons. A submarine of this sophistication might be found in the worlds leading navies. It could have remained submerged for two weeks and smuggled ten metric tons of illicit drugs with a cruising range of 3,000 nautical miles. Although we do not expect submarines to become a common drug smuggling tool, this impressive vessel shows the kind of technology that millions of illicit dollars can buy.
Good thing we have a Navy and Coast Guard that can patrol our coastline and catch... oooh, yah, I forgot thats the Americans, we really can't do this stuff unless we are lucky. :blotto:
