Spaceships Chemical Rockets - Page 2

According to the rules in Spaceships the delta-V for a chemical rocket is 0.15 mps per tank. From what I can figure, it would be impossible for a chemical rocket to achieve a delta-V high enough to make low Earth orbit even if it were multi-stage.
By my calculations, any size rocket with 1 space for engines, 1 space for armor (because of streamlining) and 18 spaces of rocket fuel could only manage a delta-V of 2.7 mps.
Am I doing something wrong? Or, is this an error in the book? The Midnight Sun's rocket engines seem to have a delta-V of 0.24 mps if you do the math with the stats they give with that example.
