In 1975, American aerospace engineer Alvin Ellis worked on a prototype for the Israeli company Tadiran: a camera attached to a model airplane (Drone Age). With this prototype, Ellis launched the modern drone industry. Many countries have begun using drones for warfare, including the United States, which has used unmanned aerial vehicles, or drones, in warfare since the 1980s. When they were first adopted, the The army only had around sixty drones. Today, drones make up about a third of all military aircraft in the U.S. military (Drone Age). Although the military has been using drones for a long time, there is still a heated debate over the ethics of using these drones to carry out drone strikes. The use of unmanned aerial vehicles in the U.S. military is ethical because they reduce material costs, are more efficient, and reduce U.S. casualties. Drones are more efficient because of their precision and reliability. Drones can go to various places inaccessible to humans, such as contaminated areas (UAV). They can also fly in areas where air defenses are not fully controlled. The US military has many types of drones in its arsenal that are used for many different purposes. The famous Predator, created by General Atomics, carries out drone strikes while the Raven carries a peanut-sized camera intended for surveillance missions (Drone Wars). This shows that drones can be used to accomplish various missions, including reconnaissance and drone strikes. US drones have carried out hundreds of strikes in six foreign countries over the past decade (Drone Ethics). These drone strikes are more precise than conventional bombs. In addition to being more effective, drones help reduce the number of American casualties amid destruction on the battlefield. Laura. “The age of drones”. Popular Science August 2012: 92.
