Officially known as the Emergency Integrated Lifesaving Lanyard, EMILY is a remote-controlled buoy recently used to rescue nearly 300 Syrian migrants from drowning off the Greek island of Lesbos, Office of Naval Research officials announced May 5.

Outfitted in bright orange, red and yellow colors, each cylindrical EMILY buoy is 4-feet long and weighs 25 pounds. It’s powered by a jet engine system similar to a mini jet ski, shoots a water jet stream for propulsion and travels up to 22 mph. EMILY also has two-way communication radios, a video camera with a live feed to smartphones and lights for night rescues.
