The Integrity-class dreadnaught was an experimental design, launched in 4130 by the Fourth Republic. The Integrity was meant to serve as a command and control ship, coordinating and repairing smaller vessels in battle. To this extent, the dreadnaught was equipped with five gargantuan repair bays, each capable of holding an Aurora-class cruiser or Pegasus-class destroyer. The idea was that up to five badly-damaged vessels could slip into the Integrity's repair bays, where the dreadnaughts powerful shields and thick armor would protect the wounded ships. If the damage was relatively minor, a ship could be repaired with the full resources of a Spacedock and return to the battlefield.
