TheFeng Bao 1 (Chinese:风暴;lit. 'Storm'), also known asFB-1, was a Chinesecarrier rocket launched between 1972 and 1981. It was replaced by the nearly identicalLong March 2, which had been developed at the same time for political reasons related to China'sCultural Revolution.[1]

The Feng Bao was derived from theDF-5 missile. Eleven were launched, of which four failed.[2] Launches occurred from LA-2B at theJiuquan Satellite Launch Centre.
