ABOARD THE HIGH SPEED VESSEL SWIFT — Drug smugglers who race across the Caribbean in speedboats will typically jettison their cargo when spotted by surveillance aircraft, hoping any chance of prosecuting them will vanish with the drugs sinking to the bottom of the sea.The devices should allow authorities to detect and monitor suspected drug shipments from afar for longer sustained periods, giving them a better chance of stopping the smugglers. They also should allow them to make continuous videotapes that can be used in prosecutions.The drone, officially a Puma All Environment unmanned aircraft system from Aerovironment Inc. of Simi Valley, California, splashed into the water on one landing and had to be retrieved. On the second round, it clacked noisily but intact on the shifting deck of the 321-foot ship. Rear Adm. Sinclair Harris, commander of the Navy’s 4th Fleet, said the devices are necessary at a time when the service is making a transition to smaller, faster ships amid budget cuts.
