OMS as such is Orbital Maneuvring System = two rocket engines used for major correction manoeuvres of orbiter and for deorbit manoeuver (as other people wrote already). OMS-2 is used to denote the maneuver in the first apogee after lift-off of the shuttle. The number 2 stems from the fact, that the shuttle was making another maneuver with OMS engines shortly after cut-off of the main engines (SSME MECO) and after separation of external tank (ET). This maneuver denoted as OMS-1 was used only in the very beginning of shuttle program and later was abandoned as unnecessary. . Tony V.
