One of the narco submarines captured called Bigfoot is on display here at the Truman Annex, Naval Air Station (the exact location needs to be determined).

Narco-submarine

A narco-submarine (also called narco-sub, drug sub and Bigfoot submarine) is a type of custom-made ocean-going self-propelled submersible vessel built by drug traffickers to smuggle drugs. They are especially known to be used by Colombian drug cartel members to export cocaine from Colombia to Mexico, which is often then transported overland to the United States.^[2][3]
