The U.S. Coast Guard offloaded more than 76,000 pounds of illegal drugs in Florida—the largest single-operation seizure in its history—worth $473 million.

The haul, including over 61,000 pounds of cocaine and 14,000 pounds of marijuana, could have supplied 23 million lethal doses of cocaine.

Part of Operation Pacific Viper, the seizure involved multiple interdictions in international waters with support from the U.S. Navy, Customs and Border Protection, and the Royal Netherlands Navy, resulting in 34 arrests and 11 vessels intercepted, Fox News has reported.
