Long March 3B/E

The Long March 3B carrier rocket is a large three-stage liquid bundled rocket developed on the basis of the Long March 3A and Long March 2 bundled rockets. The core stage is basically the same as that of the Long March 3A rocket, while the booster and its bundling structure are basically the same as those of the Long March 2 bundled rocket. It shows that four liquid rocket boosters with the same bundle as the Long March 2 are bundled around the first stage rocket of the Long March 3A and the second stage rocket is increased.
