In this paper, some early research on drag reduction technology is briefly reviewed and the existing representative underwater turbulence drag reduction technologies are analyzed and discussed in detail. And then the research actualities of riblet surface drag reduction technology, microbubble drag reduction technology and hydrophobic/superhydrophobic surface drag reduction technology are expounded through experimental and theoretical researches with drag reduction mechanisms purposively emphasized. In addition, the drag reduction technologies by compliant coating and wall oscillation are also briefly described. Finally, future development of underwater drag reduction technology and its application are prospected.
