      Variant Notes
      Sixteen hydrazine mission-module thrusters: four trajectory-correction units plus two redundant six-thruster attitude branches, matching the existing source-backed Voyager integrated-system boundary.

      Variant Notes
      Eight hydrazine reaction engines on the Voyager propulsion module retained as a separate maneuvering role; no individual thruster model is inferred.
    Name
    Voyager 2 hydrazine propulsion and attitude-control installation
    Notes
    Integrated Voyager 2 hydrazine subsystem only. The 16 mission-module thrusters and eight propulsion-module reaction engines are separated by role and module. The separate cold-nitrogen reaction-control subsystem and Voyager solid motor are intentionally omitted because this packet models only the documented hydrazine system.
