From my previous posts I’ve shared with you the information of the Predator UAV class. Today I will bring you a variant of the Predator called the Mariner unmanned aerial vehicle. The mariner is a highly successful UAV airplane intended for use as a long endurance maritime and border surveillance missions. This variant can be equipped with extra fuel allowing it to fly on long missions up to 49 hours. That’s 2 whole days, no human would be able to sit in a plane for that long and keep sane. With the ability to carry 800 pounds of internal payloads the mariner also has the ability to carry external payloads up 3,800 pounds providing for multiple missions able to be accomplished from a single UAV.
