The Taurus has been created by adding the stages of Pegasus
(without wing and fins) to a Peacekeeper first stage or a Castor-120. It has been designed as a quick reaction
launch vehicle, which can be launched from minimaly prepared places in a matter of a few
days. The coding of variants is as below:
1. digit = first stage (1 = TU-903; 2 = Castor-120)
2. digit = size of fairing (1 = small, 2 = large)
3. digit = type of Stage 4 (1 = Orion-38, 3 = Star-37FM)
4. digit = type of optional Stage 5 (0 = none)
It is not yet clear, how the XL versions will fit into this coding system.
