Planes and boats aren’t the only way to transport drugs across water.

The DEA said Saturday it helped Ecuadorian officials seize a submarine that could have transported tons of cocaine, the Associated Press reported. It was seized near a tributary close to the Ecuador-Colombia border before it could make its maiden voyage.

AP reported that the sub had a diesel electric-powered engine, air conditioning, periscope and was constructed in a remote jungle area.
