US President Donald Trump's administration has touted its success in recent weeks at taking out suspected drug trafficking vessels.
The military said in a post on X that the vessel was "engaged in narco-trafficking operations".
Reuters could not immediately verify the information.
Ecuador's Maritime Rescue Coordination Center is coordinating the search and rescue operations, the US Coast Guard said in a statement, adding that it is providing technical support.
