The ship was discovered by the Colombian Navy on May 9.5, while the ship was on its way to Central America, according to AFP news agency on May 12.5. This is the route used by drug gangs to smuggle drugs into the US.
All of the crew on board are Colombians, aged 45, 54 and 63 respectively. The Colombian Navy said the three sailors claimed that they were controlled by a drug trafficking organization to control the ship.
Over the past three decades, the Colombian Navy has confiscated 3 homemade semi-submarines. The reason they are called semi-submersibles is because they do not completely move underwater, but only partially submerged, but still enough to escape the observation of the Coast Guard.
Some of the ships were captured en route to the US, while others were intercepted in the Atlantic Ocean, while heading towards Europe.
The ship seized on May 9.5 is also the largest semi-submarine carrying drugs since 1993 in the country.
How much does a Colombian drug dealer's homemade submarine carry?
The Colombian Navy estimated the total drug value on board at about $103 million.
The law of Colombia, the world's largest cocaine producer, punishes anyone who uses, makes, sells, possesses or transports a semi-submarine to a maximum of 14 years in prison.
