Mysterious Chinese Warship Hiding Something Massive Inside

China may be building a massive mothership capable of deploying giant underwater drones, potentially giving its navy a dangerous new way to operate far beyond its own coastline. Satellite images have revealed a mysterious 670-foot vessel under construction in Shanghai, featuring an unusual stern mechanism that analysts believe could launch and recover unmanned submarines nearly 150 feet long. Meanwhile, off the coast of Florida, a group of fishermen made an extraordinary discovery when they pulled an American military attack drone from the ocean. The aircraft was a LUCAS, a roughly $35,000 one-way attack drone based on Iran's infamous Shahed-136, a design the United States has now turned against Iran itself. In Ukraine, engineers have found an even more unusual way to weaponize old Soviet technology, converting a BTR-60 armored personnel carrier into a remote-controlled bomb and sending it toward Russian positions without a single soldier aboard. And in a major breakthrough for underwater warfare, Britain and the United States successfully tested a robot submarine capable of launching an American Mk 48 heavyweight torpedo, demonstrating how unmanned underwater vehicles could eventually threaten enemy warships without risking submarine crews. From mysterious Chinese drone carriers and American copies of Iranian weapons to explosive robotic tanks and torpedo-armed submarines, these four developments reveal how quickly modern warfare is changing. The next generation of military weapons may not need pilots, drivers, or even sailors aboard—and some of the most dangerous machines on the battlefield could be operating completely unmanned. --- Dark Footage showcases the most unbelievable photos and videos from history while telling the stories behind the camera.
