Nearly a year after deploying more ships and aircraft to the waters around South and Central America, the Navy and Coast Guard continue to make multi-ton drug busts, and their personnel are engaging suspected smugglers on a daily basis, the top U.S military commander in the region said in January.

U.S. Southern Command, which oversees U.S. military operations in the region, began enhanced counternarcotics operations on April 1, acting on a directive from then-President Donald Trump to further disrupt the flow of drugs to the United States.

Since then, Navy destroyers, littoral combat ships, and helicopters, Coast Guard cutters and helicopters, and Navy and Air Force patrol and reconnaissance planes have increased their presence in the region.

At the Surface Navy Association symposium in mid-January, Adm. Craig Faller, head of Southern Command, said the sailors involved “are making a difference.”
