The Tactical Department is responsible for keeping the ship safe from external threats.  From their post on the bridge, they control shields, phasers, torpedoes, and most of the ship's sensor arrays.  The Hyperion has heavier weaponry than a Sovereign Class vessel as well as heavier shielding.  It's Tactical's job to keep these systems running smoothly during battle.

     The Hyperion's Tactical department consists of 10 to 15 men including 5 officers.  The Chief Tactical officer is Ensign Ivan Drakov.

USS Hyperion Total Tactical Armaments

Weapon Systems
      Primary: 12 Type XII Phaser Arrays
      Secondary: 1 Rapid Fire Quantum Torpedo Turret (600 Torpedoes)
                           4 Burst Fire Photon Torpedo Launchers (500 Torpedoes)
      Tertiary: 1 Spinal Mounted Plasmic Phaser Cannon

      *The Plasmic Phaser Cannon was developed in coalition with the Romulans and Klingons during the war with the Dominion.  The cannon works by dropping a sphere of plasma into a tube coated in a negatively charged conductor.  As the sphere is shot through the tube, the conductors are changed to a positive charge, repelling the sphere.  This gives the plasma sphere great velocity.  However, while its damage is great, it is unidirectional and drains vast amounts of power.
 

Defensive Systems
Shields: Triple Layered Multi-Phasic shielding.
Armor: Ablative Hull Armor

    The Tactical Department is also responsible for coordinating away missions.  Using Tricorders and Communicators, they can keep tabs on all the crew members and beam them out in dire circumstances.  Transport pattern buffers can also be used to enhance weak signals in order to help extract trapped crew members.

    Security is responsible for responding to internal threats to the ship.  They are also responsible for keeping away teams safe on away missions.  They also responsible for breaking up fights if they occur.  The Hyperion also has several types of phasers in it's armory.  Listed below are a few types.

    Hyperion's Security Contingent consists of about 50 men including 15 officers.  The Chief Security Officer is Lt. Commander Reyaga.
