Watch the Ninox 103 launch from the submerged submarine in the video below. The system has been successfully tested, and Spear is collaborating with a number of defense companies as it continues to work on new developments.” “The first technological development of its kind in the world, the Ninox 103 Sub-to-Air has been developed in response to the needs of Spear’s customers worldwide for a drone capable of underwater launch. (Credit: SpearUAV) (Credit: SpearUAV)Ĭolonel (Retired) Gadi Kuperman, SpearUAV Founder & CEO, said: In addition, encrypted communications, cross-domain connection, and third-party data integration are used to communicate with the submarine, other platforms, or special forces units ashore. The drone has a payload of 2.2 lb (1 kg) and contains Electro-Optical/Infra-Red (EO/IR) sensors for surveillance and autonomous target acquisition using its open-architecture AI system. The Ninox 103 has a range of 6 miles (10 kilometers) and a 45-minute endurance once airborne. Then, before the durable, maritime-hardened drone launches, its capsule floats to the surface and can stay dormant for up to 24 hours. However, these tended to be fixed-wing aircraft, while the Ninox 103 is based on a quadcopter design that enables it to hover in place.Īccording to SpearUAV, the Ninox 103 is stowed in a submarine-deployable capsule.
In 2013, navies turned to underwater-launched drones as a reconnaissance tool. Gyrocopters, kites, and even airplanes have been launched from submarines with varying degrees of success, but all of them had the issue of requiring the boat to the surface to deploy them. This is why submariners have experimented with various ways to extend their views for over a century. However, they’ve had the disadvantage of not being able to see what’s happening above the waters beyond the horizon of a periscope. Submarines have a significant strategic and tactical advantage due to their ability to submerge. The submarines could then engage enemy ships or slip away in the darkness.Israeli drone maker SpearUAV has released the Ninox 103 UW Sub-to-Air encapsulated autonomous quadcopter, which it says is the world’s first loitering drone that can be launched from a submarine or other submerged platforms for immediate situational awareness beyond line-of-sight. IJN doctrine stated that the Type 3 was to be covertly deployed off the coast, ideally at night, to reinforce island defenses or deliver supplies. To achieve this, the Type 3’s rear hull was made of a single convex plate that was riveted to the tank. This could be done even when the submarine was submerged. The biggest improvement of the Type 3 over the Type 2 was its ability to launch from a submarine. The Type 3 had a crew of seven including a dedicated on-board mechanic. The Type 3 was also equipped with two Type 97 7.7mm machine guns: one mounted coaxially in the turret and other mounted in the bow. Although it was only capable of perforating the frontal armor of an M4 Sherman, the 47mm gun could penetrate its sides and do serious damage to light tanks like the M3/M5 Stuart from any angle. The Type 3 was armed with Japan’s standard anti-tank gun, the Type 1 47mm. A large snorkel behind the turret delivered air to the Type 3’s Mitsubishi V-12 diesel engine and kept water out of the engine compartment An extra cupola was built on top of the turret to keep water out of the fighting compartment as well.Ī Type 3 on the ramp of a landing ship (Public Domain) Propulsion in the water was achieved with twin-screws with primary steering provided by two more. The extra metal of the pontoons, although very thin, served as a bit of spaced armor and most crews kept their pontoons attached. When the Type 3 reached land, its pontoons could be released by the crew from inside. Take a dive and marvel at coral reefs and marine life from a. The stern pontoon hosted two rudders to assist with steering. Explore the crystal blue waters of Kona on the Big Island in this submarine adventure. The bow pontoon curved up for improved hydrodynamics and split down the middle for mounting and dismounting. These were sheet metal and attached at the bow and stern of the tank. Most importantly, it could be fitted with two additional pontoons. It was welded together and sealed with rubber gaskets. The Type 3’s sides were flat and box-like for streamlining in the water.
