CZ-2E(A) Chronology 2000 October 14 - Launch Vehicle: CZ-NGLV-504, CZ-2E(A), CZ-1D. - China Reveals New Launcher Detail Nation: China. During the International Astronautical Federation (IAF) annual congress in Rio de Janeiro, China unveiled deatils of its new CZ-5 heavy launch vehicle family. Powered by kerosene/LOX/LH2 engines and four strap-on boosters, the new 800-ton, 50-55-meter high launcher would be capable of lifting 23 tonnes into LEO and 11 tonnes into geostationary transfer orbit. The CZ-2E(A), equipped with new avionics from the man-rated CZ-2F, was to be tested by 2003. The CZ-1D small launcher was slated to make its first flight in 2001, while yet another small launcher, a 4 stage solid rocket, was under design.References: 424.
