As is well known, electronic components are afraid of water, and there are many drones that "explode" every year due to falling into the water. The Bazna UAV of a company in Türkiye can take off from underwater. Bazna drone is an FPV drone with a waterproof design, which ensures that even if the entire machine is submerged in water, its operation is not affected. After startup, the machine can directly ascend from underwater. When taking off from land, it adopts the traditional vertical takeoff and landing method. After takeoff, it can fly at a speed of 120 kilometers per hour for 15 minutes. In addition to being used as attack ammunition, this drone can also perform reconnaissance and surveillance tasks. With the support of new communication technologies, it has certain electronic protection capabilities and can better cope with unexpected situations such as electromagnetic interference and even signal interruption. The designer has endowed the drone with thermal imaging capability, so it can also be used at night. At present, in addition to using it for border security operations, relevant parties in Türkiye are also discussing how to integrate it with unmanned ships at sea to play a greater role. With the development of technology, a large number of unmanned aerial vehicles with different forms and strengths are being applied in the military field. Due to the "unmanned" nature of drones, they have significant differences in takeoff methods compared to manned aircraft, such as hand throwing, aerial shooting, and submarine shooting. (New Society)
