The ChangKong-1 is a radio-controlled , jet-powered subsonic unmanned aerial vehicle developed from the Soviet Lavochkin La-17C. Developed by Nanjing Institute of Aeronautics in the late 1960s, the ChangKong-1 has been in serving with the PLAAF since the late 1970s for target drone and nuclear air sampling roles.

長空（ChangKong）-1是一種無線電-控制、噴氣動力亞音速無人機基于蘇聯Lavochkin La-17C型發展。在1960年后期由南京航空學院發展，長空-1型從1970年后期以后在PLAAF服役用于靶機和核空氣取樣任務。

The PRC obtained a small number of the Lavochkin La-17 radio-controlled, ramjet-powered target drone from the Soviet union in the late 1950s. These drones were being sued for airborne- and air-defence weapon testing and practicing. Acquisition of additional units was unsuccessful due to Moscow’s decision in 1960 to stop all of its technical aids to the PRC. This forced the PLA to develop its own indigenous target drone ChangKong-1.

在1950年后期中國從蘇聯獲得了少量Lavochkin La-17型無線電-控制，噴氣動力靶機。這些無人機用于機載-和防空武器測試和練習。另外的單位在1960年由于莫斯科決定停止對中國所有它的技術幫助而無法獲得。這迫使PLA發展本國的靶機長空-1型。

The ChangKong-1 project began in the early 1960s, with the development work carried out by the PLAAF Weapon Test & Training Base. The chief designer of the programme is General Zhao Xu, who is known as ‘the Father of Chinese uav’. Several La-17C examples were dissembled by Chinese engineers for study and reverse engineering. Because of the PRC’s incapability to produce a suitable ramjet engine, the indigenous target drone was powered by a Wopen-6 (WP-6) turbojet engine originally developed for the Shenyang J-6 (MiG-19 Farmer) fighter.

長空-1型計劃在1960年早期開始，由PLAAF武器測試和訓練基地進行發展工作。計劃的設計總負責人是中國工程院院士趙煦將軍，也被譽為‘中國無人機之父’。一些La-17C型樣機是為研究和反向工程被中國工程師掩飾。因為中國沒有能力生產一種合適的沖壓式噴氣發動機，國產靶機動力由一臺渦噴-6（WP-6）渦噴發動機提供，最初用于沈飛J-6（米格-19“農夫”）戰斗機。

The ChangKong-1 successfully flew in December 1966, but the development programme was severely disrupted by the political impact of the ‘Culture Revolution’ in the 1960s~70s. The ChangKong-1 development was resumed by Nanjing Institute of Aeronautics (now Nanjing University of Aeronautics & Astronautics, NUAA) in the 1970s and the development did not finish until 1976, eight years after the project began. The ChangKong-1 entered PLAAF service in the late 1970s for weapon testing and air defence training.

長空-1成功地在1966年12月飛行，但是發展計劃由于某些原因在1960年~70年受到干擾。在1970年長空-1發展被南京航空學院重新開始（現在南京航空航天大學，NUAA）和發展直到1976年前沒有完成，這已經在計劃開始8年之后。在1970年后期長空-1型用于武器測試和防空訓練進入PLAAF服役。
