- Total : 850;
- Permanent life support capability: 5000 humanoids;

- Height: 103 meters (main hull), 148 meters (over all).
- Mass : 140,000 tons.
- Gravitic Maneuvering Drives: The standard reaction
engines installed in all Zentraedi and Earth ships have been omitted in favor of three
gravitic maneuvering drives. These drives are smaller versions of the main sub-light
drives and are mounted on the three axis of the ship. The use of these drives in unison
will create the required thrust into any direction, thus eliminating the maneuvering
problems present in the larger drive. These smaller drives are rated for a maximum
acceleration of 1.8g. Also, the drives do not use reaction mass and can thus be operated
- Gravitic Displacement Drive for sublight travel: Local,
monopolar-induced gravitic space-time distortion, powered by main protoculture reactors,
accelerates vessel at 400-500 g, but the vessel's maneuverability is reduced to such a
degree that only minor course corrections are possible. Typical cruising speed is .001 C,
though higher speeds can be achieved.
- Space Fold: A hyperspace system that catapults the
vessel through space-time. The spacefold system is used for traveling from one system to
another quickly. The strapped-down system used onboard the Destroyers was of the
conformal type and limited to distances of about 100 parsecs (326 ly) per hyperspace
- Planetary Capability: The Destroyers can operate in an
atmosphere, but are due to their size constrained to sub-sonic speeds. Planetfall is also
possible, given a sufficiently large flat area with a bedrock underground or a body of
Endurance and mobility limits:
- Effectively limitless through fold and sublight drive systems. Protoculture reactors
function for 50-65 years, depending on the individual system's design age and the level of
- Reflex Cannon: An incredibly destructive particle beam
range of over 300,000 km, mounted in the front of the vessel. The model used by the
Destroyers utilizes the same technology as the mini-Reflex cannons mounted on the
Tirolian gunships, and fires through the two lower cannon appendages, rather than
requiring the ship to open up.
The effects of this weapon against planets are equal to the heat and blast effects
of the detonation of a fusion weapon of 1.5 megatons, if fired at full power. Note that at
the time the Second Robotech War the energy levels in the Tirolian ships were so low
that the cannon could no longer be fired by most ships, and in the ships that still could
fire the cannon, the blast effect seldom exceeded 50 kilotons.
If utilized against starships, the largest vessels can be destroyed with one salvo.
The weapon can also be set to a wider dispersal. While not nearly as effective as a tight
beam against warships, it is capable of clearing a wide area of fighters and other mecha.
- Main Particle Beams: These are the main anti-ship
the reflex cannon cannot be fired fast enough in fleet actions. There are four of these
large cannons mounted in appendages on the bow, all firing in a forward arc. Another two
are located aftwards to the sides, two slightly smaller ones are mounted in movable
turrets to the front sides, and three of the smallest variant are mounted on the dorsal and
ventral surfaces. Rate of fire for the largest cannons is two salvos per minute, and the
smaller ones can fire a sustained salvo of ten seconds three times per minute. Range is a
respectable 200,000 km. Typically, one discharge of one frontal cannon has a power of
1.5 terajoules, for a total forward (four cannons firing) salvo of 6.0 terajoules, the
equivalent to 1.2 kilotons of TNT. The intermediate cannons can fire salvos of 0.75
terajoules (0.15 kilotons) and the smallest are limited to 0.3 terajoules (0.06 kilotons).
- AAA Lasers: All Destroyers mount over 120 of these
weapons. They are designed to suppress attacking mecha, constructed with the Invid's
suicidal ramming tactics in mind. 10 of these cannons are mounted on the bow, another
ten are mounted on the stern, and 25 are divided over each of the dorsal, port, ventral and
starboard hull surfaces. They can deliver 10 MJ of laser energy each and can fire every
- Absorbative & ablative hull: The hull of each Destroyer
constructed with a mix of high-density metals, ceramics and other, classified materials.
While not as effective as the more advanced Tirolian shield technologies, which the
Destroyer is too small to carry, this armor does limit the destructive impact of energy and
solids weapon systems to a certain extend.
Special Equipment of Note:
- Hyperspace communications
- Long-range laser and satellite relay communications
- Long-range radar
- Radar and communication dampeners
- Electronic warfare devices.
Mecha and Air Complement:
- Typical complements are given. If needed, these numbers can be increased.
- Bioroids: 200 to 250 units.
- Typically about 25 shuttles, recon drones and others.
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
flat ventral surfaces, two sponson-like bulges were visible, running
about a third of the vessel's length.
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
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
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
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
