One of the last Chinese Second Artillery brigades with the old liquid-fuel DF-3A intermediate-range nuclear ballistic missile appears to have been upgraded to the newer DF-21 road-mobile, dual-capable, medium-range ballistic missile.
A new satellite image posted on Google Earth from May 4, 2014, reveals major changes to what appears to be a launch unit site for the Dengshahe brigade northeast of Dalian by the Yellow Sea.
The upgrade apparently marks the latest phase in a long and slow conversion of the Dengshahe brigade from the DF-3A to the DF-21.
The range of the DF-21 is less than the range of the DF-3A (2,150 km versus 3,000 km), but the DF-21 system is much more capable than the DF-3A. Unlike the liquid-fuel, transportable DF-3A, the DF-21 is a solid-fuel missile carried on a road-mobile transporter erector launcher (TEL). As such, the DF-21 TEL can move around the landscape much more freely and can set up and fire its missile quicker than the DF-3A system. The DF-21 is also more accurate, which is reflected in a smaller warhead – 200-300 kilotons versus 3,300 kilotons for the DF-3A warhead.
From the launch pads north of Dalian, the DF-21 would able to target all U.S. military bases on the Japanese mainland as well as on Okinawa.
