Fleet of Destroyers near Mothership

The Tirolian Destroyer was conceived to be a fast, heavily-armed vessel for fleet escort, patrol, and assault duties. Bristling with the most armament for her size of any ship ever built, this vessel was the core of the reduced fleets operated by Tirol after she downsized her own military after the creation of the Zentraedi.

In general hull shape, the Destroyers were shaped not unlike a snub-nosed version of the later REF's Garfish-class destroyer, without the hangar, gun turret, or engines. To the outboard edges of these ships' flat ventral surfaces, two sponson-like bulges were visible, running about a third of the vessel's length.

System Destroyers

Four large sensor domes dominated the bow. Three of these were mounted in a vertical row in the bow, while the larger fourth dome was mounted on the edge of the upper deck and the prow. Flanking these sensors were the four booms of the main armament, sticking out from the ships much like the very early german air-to-air radars did in the Second World War. A fifth and sixth cannon appendage was mounted to the rear, while two smaller cannons were mounted in movable turrets between the bow and the sponsons. The AAA armament was usually hidden from view behind movable bulkheads.

Designed for naval engagements, the ships also carried a fair number of Bioroids and their sleds in five internal hangars; one near the upper deck and the other four near the lower hull.

There were no command towers on this design, the CIC and bridge being located near the core of the vessel, for maximum protection. Four large sensor booms, for local hyperspace sensors, were mounted at the rear, in a cruciform arrangement, rotated forty-five degrees from the ship's gravity-well attitude.


As the Tirolians began to expand into space, they brought a military presence with them. To defend the early colony ships and to patrol the Interstellar Republic, the Tirolians developed a number of military vessel designs; the only two that stood the test of time were the Battleship and Destroyer. With the introduction of the Zentraedi, these designs were largely abandoned. However, centuries later, as the Empire began to collapse, several of the basic designs were revived, updated with the newest technologies, and sent to the shipyards for construction. Among them was the Destroyer.

The craft was a dedicated starship-killer spacecraft in a very small hull; in fact, the vessel was smaller than its closest Earth equivalent, the Tristar-class Light Cruiser. Each Mothership was assigned three battlegroups of nine Destroyers each, and several independent groups were built as well. In total, over 1100 of these ships were built by the Tirolian overlords. The design showed its mettle during the latter days of the Empire, when system after system fell to the Invid. Its best known battles, however, are those that took place in the solar system during the Second Robotech War. Over 160 Destroyers were transported with the large Tirolian Motherships to Earth, where they exacted a terrible toll on the Southern Cross and the relief expeditions sent by the REF. All of these ships were either destroyed during the war, or lost all power in the months after the its end. A few survivors of the class were found intact in the former Tirolian Empire, and ongoing research programs are trying to duplicate the design, or at least certain key technologies, for use in a new standard REF frigate, and the successors to the both the Tristar and Garfish classes.
