China Launches Another New Rocket

KT-2 Data Sheet

China debuted the KT-2 (Kaitou 2) orbital launch vehicle on March 2, 2017. The solid-fuel, likely three-stage launch vehicle lifted off from the CZ-11 flat pad at Jiuquan space center at 23:53 UTC. KT-2 injected a small test satellite named TK-1 (Tiankong) into a 381 x 403 km x 96.9 deg sun synchronous orbit.

Xinhua reported that the TK-1 satellite was developed by CASIC to be used for “remote sensing, telecommunications and experiments in minisatellite-based technologies”.

China Aerospace Science & Industry Corporation (CASIC) also reportedly developed the launch vehicle. KT-2 may be based on the DF-31 mobile ICBM family, but that has yet to be determine.

According to Xinhua, KT-2 is one of five launch vehicles planned for development by CASIC. It is capable of lifting 350 kg to a low inclination low earth orbit or 250 kg to a 700 km sun synchronous orbit.

CZ-11, a similar DF-31 based rocket that first flew in 2015, was developed by the China Academy of Launch Vehicle Technology (CALT). Two smaller, DF-21 based launchers, both by CASIC, have also flown: Kuaizhou 1(A) beginning in 2013 and KT-1, which failed in two attempts during 2002-2003.
