"We are committed to fully funding our Coast Guard and replacing old ships with new ones, just like the U.S. Coast Guard cutter Munro".
Masson told Fox News the operations will lead to the prosecution of 55 alleged drug smugglers.
Once inside the hull, they found 17 000 pounds of cocaine (around 7,7 tonnes) worth an estimated $232 million.
The U.S. Coast Guard has offloaded tons of cocaine and marijuana seized from boats and even a semi-submarine in the Pacific.
Pence congratulated the crews of three Coast Guard cutters for confiscating the contraband from 14 suspected drug smuggling vessels intercepted off the coasts of Mexico and Central and South America between May and July.
The incredible video shows two boats from the US Coast Guard Cutter Munro the target craft from either side in Eastern Pacific waters. Firstly, it would take a lot of courage- and skill- to leap from a pitching Coast Guard RIB onto the slippery, rounded deck of a narco-submarine. "I think there's no question, that as we continue to secure our border, we're going to see the drug cartels use the open ocean to move narcotics more than they do today".
Over 16,000 pounds of cocaine were confiscated in the June 18 mission, the Coast Guard said.
And a part of of the problem is that 70 percent of Coast Guard's fleet is over 50 years old - so they're slow and require a lot of maintenance before they can be deployed.
Foxnews reports citing US Coast Guard spokesman John Masson that five intruders were discovered on the ship.
He said self-propelled semi-submersible vessels are sometimes used by traffickers to smuggle drugs in the open sea.
