The Drifting-2 (漂-2, or Piao-2) drifting mine is a small drifting mine jointly developed by the 710th Research Institute and Dalian Crane Factory. This drifting mine system is the first in Chinese service to be able to be taken apart for easier transportation, and then assembled just before being planted, and it is designed to float just below the surface of the water to avoid being visually detected. This mine is mainly for riverine and coastal use and can also be used as part of the moored mine system.
