Nigcomsat 1

 2007-018A


NASRDA (National Research and Development Agency of Nigeria). 5150 kg DFH-4 bus to go to 42E. Launch by CZ-3B/E in 2007. The enhanced rocket had 4 x LB-41/YF-25 strapons, an L186/YF-21C stage 1, an L35/YF-24E stage 2 and an H18/YF75 stage 3. Compared to CZ-3B, the strapons had an additional 1t of prop, the stage 1 had extra 6t. The solar array drive mechanism failed, limiting the ability of the satellite to operate.
