Dong Neng-3
The Dong Neng-3 (;  DN-3/KO09) is a Chinese ballistic missile defense system. Design 
The system is generally believed to be based on the DF-21 with elements of the SC-19 also incorporated. The interceptor is hit-to-kill. It can also be used as an anti-satellite weapon. The Dong Neng-3 is believed to fill much the same role as the SM-3 however it is believed to be much larger. History 
Testing of the DN-3 has primarily occurred at the Korla Missile Test Complex. A 2010 midcourse defense test was most likely a test of the DF-3. In 2015 the DN-3’s anti-satellite capabilities are believed to have been tested. In February 2018 the DN-3 was tested against a DF-21 based target in space. This test was reported to be a success by the PLA Daily. See also
