U.S. Navy successfully launches drone from a submerged submarine

First it was missiles, and now the US Navy can add unmanned drones to the list of things that can be launched from a submerged submarine. The Navy today announced that it did just that in a recent demonstration that took some six years to develop. The drone, called an XFC UAS-eXperimental, was launched in a standard torpedo tube from the Navy’s USS Providence using a similar technique to how the Navy deploys Tomahawk cruise missiles.
