Jielong 3 (Chinese:捷龙三号运载火箭, meaning "agile dragon", also known asSmart Dragon 3,SD-3), is a solid fueled orbital launch vehicle developed byChina Academy of Launch Vehicle Technology's subsidiaryChina Rocket to launch up to 1500 kg to a 500 km altitudeSun-synchronous orbit (SSO). The rocket is 31 meters tall, 2.65 meters in diameter and weighs 145 metric tons. It is a solid fuel, 4 stage orbital rocket.^[2] The fairing diameter is 3.35 m. It uses the same rocket motors as theZhongke-1 (ZK-1, Lijian-1) rocket.

The maiden flight of Jielong 3 on 9 December 2022, 06:35 UTC was successful. It delivered fourteen small satellites into polar orbit. The satellites wereJilin-1 Gaofen-03D-44-50 and Pingtai-01A01, HEAD 2H, Jinzijing Qilu-1 05 and 06, Tianqi 07, Huoju 1 (Torch 1) and CAS 5A. The launch took place from a floating platform offYantai,Shandong.

The carrying capacity of the Jielong 3 launcher initially stood at 1,560 kilograms to 500 kilometres SSO orbits, but this has since increased to 1,600 kilograms by the rocket's fifth launch on 13 January, 2025. Also in January 2025, Gao Lijun from the China Aerospace Science and Technology Corporation (CASC) stated that further improvements will be made to the rocket in order to enable it eventually to carry up to two metric tons to 500 km SSO orbits.^[1]
