Coast Guard nabs another drug sub

MIAMI — The crew of the Coast Guard Cutter Mohawk, a medium-endurance cutter homeported in Key West, Fla., interdicted a drug smuggling, self-propelled semi-submersible (SPSS) vessel, known as a drug sub, in the western Caribbean Sea Sept. 17. This is only the second such interdiction, involving a semi-submersible. The Seneca nabbed the first one on July 13. 

The crew of a Coast Guard C-130 Hercules airplane spotted a suspicious vessel and notified the Mohawk crew of the location. The Hercules is designed for long range law enforcement patrols to allow identification and tracking of suspect vessels as well as search and rescue missions.

With the assistance of the Hercules crew, a Mohawk-based Coast Guard helicopter crew and pursuit boatcrew interdicted the SPSS and detained its crew. The SPSS sank during the interdiction, but not before a quantity of cocaine was recovered.

You can hear Mohawk commanding officer Cmdr. Mark J. Fedor talk about the interdiction here.

Built in the jungles and remote areas of South America, the typical SPSS is less than 100 feet in length, according to the Coast Guard, with four to five crewmembers, and carries up to 10 metric tons of illicit cargo for distances up to 5,000 miles. Drug traffickers design SPSS vessels to be difficult to spot and to rapidly sink when they detect law enforcement thereby making contraband recovery difficult.

“The use of self propelled semi-submersibles is relatively new in the Caribbean so it’s a serious operational challenge for the cutter fleet,” said Cmdr. Mark Fedor, Coast Guard Cutter Mohawk’s commanding officer, in a statement. “They are a significant threat to our nation and our friends throughout Central and South America because they can smuggle massive amounts of narcotics as well as other illicit goods or people. I am proud of my crew for stepping up to this challenge. Through their professionalism and courage, we were able to stop millions of dollars of cocaine from reaching the streets of America. That’s why we’re out here.”

“This is a great example of how our cutters and people stop threats to the United States long before those threats reach our shores,” said Rear Adm. Bill Baumgartner, commander of the 7th Coast Guard District, in a statement. “Medium endurance cutters like the Mohawk are built for multi-week offshore patrols including operations requiring helicopter and pursuit boat capabilities. The bulk of the medium endurance cutter fleet is approximately 40 years old and slated for replacement by the new Offshore Patrol Cutter. In fact, Mohawk is the youngest of her type at 21 years old. The new cutters will ensure we continue to detect threats far from U.S. shores and meet the demands of the Coast Guard’s homeland security, search and rescue, and law enforcement missions.”

The case is under investigation. The contraband and suspects were turned over to other U.S. law enforcement agencies for disposition.
