SpearUAV has released its Ninox 103 UW Sub-to-Air encapsulated autonomous quadcopter, which it claims is the first loitering drone that can be launched from a submarine and other submerged platforms for immediate beyond-line-of-sight situational awareness.With their ability to submerge, submarines have a major strategic and tactical advantage. However, from their inception they've also suffered since from the disadvantage of not being able to see what's going on above the waves beyond the horizon of a periscope.For this…

All-electric submarine manufacturer U-Boat Worx has announced its latest series of submersibles called NEXUS, comprised of seven- and eight-person vessels (nine if some are children). These electric submarines are powered by lithium-ion battery technology allowing them to operate for up to 18 hours and dive 10 times a day. In addition to providing eco-friendlier ocean exploration, they look cool as hell. U-Boat Worx is a Dutch submersible manufacturer that began as a dream by founder Bert Houtman in the 1980s. The…
