There's no denying the impact drones have had on the world's military operations in the 21st century, as the future of warfare is drone warfare. Military drones come in all shapes and sizes, including one that looks like a killer whale. Ukraine successfully employed various naval drones against its aggressor in the Russo-Ukrainian War, and those innovations have had an impact. Developers around the world are working hard at coming up with all kinds of naval drones. Should the Ranger move forward and find its way onto the world's submarines, it could have an immense impact on future military submarine operations.
