The US military may soon welcome some new additions to its fleet of unmanned aircraft, with the Navy revealing plans to purchase a set of small drones that can be launched into the air from submarines and other underwater vehicles.
The Blackwing drones are launched from a three-inch canister aboard submarines or unmanned underwater vehicles, as part of already installed systems used for acoustic countermeasures. They could be daisy-chained to boost communications and potentially even weaponized as a self-defense option.
