A drug submarine seized in Ecuador, first time they captured the full underwater Narco-Submarine. Since 2006, when the first Self-Propelled Semi-Submersible (SPSS) watercraft was detected, 47 have been captured at sea and on land, including 17 last year. So far this year, only three such craft have been captured. The stat below is from 2008. I wonder how many of them are on voyage right now..
