It’s been the Navy’s dream for years: undersea drones that can swim entire oceans. But it’s been thwarted by science’s inability to build propulsion and fuel systems for a journey of that length. Still, the Navy’s top officer and its mad scientists think that some recent research could help turn the dream into an ocean-crossing reality.
“I’m very much desirous of that end-state, cross-ocean, as feasible,” Adm. Jonathan Greenert, the chief of naval operations, told reporters on Friday. “There are a few propulsion systems that can give you that range — 30-day, 45-day.
