in 1959, the us air force ,concerned about losing pilots over hostile territory ,began planning for the use of unmannned aircraft ,planning intensified after the soviet union shot down a u-2in 1960.within days ,a highly classified uav program started under the code mane of red wagon ,the august 1964 clash in the tonkin gulf between naval unted of the us and north vietamaese navy intiated america highly classified uav into their first combat missions of the vietman war,,when the chinese govement showed photo of downed us via wide world photo ,the offical us response was no comment the war of attrition was characterized by introduction of uav via wide world reconnaissance cameras into combat in the middle east in the yom kippur war israel uesd drones as a decoys to spur opposing forced into wasting expensive anti aircraft mmissiles.

in 1849,austraria sent unmaned, bomb -filled balloms to attack venice ,uav innovations started in the early 1900s and orginally focused on providing practise targets fro training military prosonal, uavdevelopment contunued during world war ,when the dayton wright airplane company in vented a pilotles aerial torpedo that would explode at a present time, the earliest attempt at a powered uav was a.m low’saerial target in 1916.nikola tesla described afleet of unmanned aerial was am low’saerail target in 1915.advances followed during and after world war i,including the hewittsoerry automatic airplance,the first scaled remote piloted vehicle was delveloped by film star and model-airplane enthusiast reginald denny in 1935,more uav s emerged during world war 2 used both to train anriarcraft gunners and to fly attack missions nazi germany produced and used various uav air craft during the war,jet engines entered service after world war2 in vehicles such as the austrilian gaf jidivik ,and tech ryan firebee 1of 1951 ,while come paines like beech raft offered their modle 1001 for us navy in 1955,nevertheless they were little more than remote controlled airplanes until the vietnam war.

multiple terms are used for unmanned aerial vehicles,which generally refer to the same concept. The term drone,more widely used by th public,was coined in reference to the re-semblance of navigation and loud-and -regular moter sounds of old military unmanned aircraft to the male bee.The term has encountered strong opposition from professionals and government regulators. the term unmanned aircraft system was adopted by the us department of defense and the united states federal aviation administration in 2005 according to their unmanned aircraft system roadmap 2005-2030.the international civil also used in the european union’ssingle european sky air traffic management research roadmap for 2020.this tern emhasizes the improtance of elements other than aircraft , it includes elements such as ground control stations ,data links and ther support equipment .a similar term is an unmanned aircraft vehicle system remotely piloted aerial vehicle ,remotely piloted aircraft system .many similar terms terms are in use. a uav is defined as “apowered aerial vehicle ,which does not carry a human operator, uses aerodymanic forces to provide lift ,can fuly automomously or be pilote remotly ,canbe expendable or recoverabe,and can carry a lethal or nonlethal payload , therefore,missiles are not considered as uavs,bucance the vehicle itselft is a weapon that is not reused,though is ti also unmanned and in some cases remotely guided. the relation of uavs to remote controlled model aircraft is unclear .uav may or may not include model aricraft ,some juridicions base their definition on size or witght m,however ,the us federal aviation adininstration definedsany unmanned flying craft as a uav regardless of size ,a redio controlled aircraft becomes adrone withe the addition of an auto pilot arificial intelligensce,and ceases to be a drone whten the ai is removed.

An Unmanned Aerial Vehicle,commonly known as a drone,Unmanned Aircraft System,or by several other manes,is a aircraft without a human pilot a -board .The flight of UAVs may operate with various degrees of auto nomy: either under remote control by a human operator,or fully or intermittently autonomously,buy airbornes computers. compared to manned aircraft ,uav are often preferred for missions that are too”dll ,dirty or dangerous”for humans,they orginalted mostly in military applications as shown in fig,1-1,although their uses are expanding in commerial,scientific,recreational,agricultural and other applications,such as policing and surveillance,drone delivery,aerial and photography ,agriculture and drone racing ,civilian drones now vastly outnumber military drones,whith estimates of over a million sold by 2015.
