Larger UAVs are used for strategic reconnaissance. The most important of these is the U.S. RQ-4 Global Hawk, a jet-powered craft 44 feet (13 metres) long and with a wingspan of 116 feet (35 metres). The Global Hawk has a cruise speed of 400 miles (640 km) per hour and an endurance of some 36 hours, and it carries a variety of photographic, radar, and electronic sensors.

Whyare lithium batteries dangerouson planes

NOTE: A lithium-ion battery could be damaged and not exhibit any of these signs immediately. Damaged lithium-ion batteries can heat up uncontrollably, resulting in fires, off-gassing flammable and toxic vapors, and explosions. Damaged lithium-ion batteries can pose a risk after the initial damage; some were observed to have reignited days after the original damage.

Many electronic devices and vehicles are operated by rechargeable lithium-ion batteries, which can cause fires or explode if they are damaged. Damage to a lithium-ion battery in an accident can cause the cells to discharge energy and heat up, leading to “thermal runaway,” which can cause the cells to ignite and burn. Additionally, saltwater inundation may cause short-circuiting that leads to the same result. This has been documented in places such as Florida after Hurricane Ian, which had 21 electric vehicles (EVs) according to the State Fire Marshal’s Office.

UAVs are descended from target drones and remotely piloted vehicles (RPVs) employed by the military forces of many countries in the decades immediately after World War II. Modern UAVs debuted as an important weapons system in the early 1980s, when the Israeli Defense Forces fitted small drones resembling large model airplanes with trainable television and infrared cameras and with target designators for laser-guided munitions, all downlinked to a control station. Rendered undetectable by their small size and quiet engines, these vehicles proved effective in battlefield surveillance and target designation. Other armed forces learned from the Israeli success, notably the United States, which purchased some of the early Israeli models or produced them under license. The most important American tactical UAV—and one that is representative of trends in the development of these aircraft—is the MQ-1 Predator, which first flew in 1994 and entered service the following year. The Predator, with a length of 26 feet 8 inches (8 metres) and a wingspan of 41 feet 8 inches (12.5 metres), is powered by a piston engine driving a pusher propeller. It flies at 80 miles (130 km) per hour and has an endurance of 24 hours. In addition to visible and infrared television, it carries synthetic aperture radar and passive electronic sensors, and it can also carry antitank missiles. Control inputs and sensor outputs are transmitted via communications satellite. A larger, turboprop-powered derivative of the Predator, the MQ-9 Reaper, has improved performance and carries a larger ordnance load. Both the Predator and the Reaper have been used in the conflicts in Iraq and Afghanistan and have been purchased by allies of the United States.

Extremely small UAVs, in some cases hand-launched, are used to extend the vision of ground combat units beyond their front lines. For more information, see military aircraft: Unmanned aerial vehicles.

unmanned aerial vehicle (UAV), military aircraft that is guided autonomously, by remote control, or both and that carries sensors, target designators, offensive ordnance, or electronic transmitters designed to interfere with or destroy enemy targets. Unencumbered by crew, life-support systems, and the design-safety requirements of manned aircraft, UAVs can be remarkably efficient, offering substantially greater range and endurance than equivalent manned systems.

There are, however, steps you can take to protect your lithium-ion battery-powered vehicles and equipment and safeguard your family and property. Understanding and following safety precautions is crucial to prevent accidents and ensure the longevity of your devices.
