At least one Cyclone mecha is available for each pilot, as well as a variable number for ship security and such.
There is sufficient room in the main hull hangar for ten Alpha/Beta combinations instead of the 24 Alphas.


Design notes:

The Shimakaze class design started as an attempt to design a vessel that could replace three older ship classes in the Robotech Expeditionary Forces: the Tristar-class large cruisers, the Battle-class heavy cruisers, and the Garfish-class light scout cruisers. Although it was intially hoped that this could be achieved on a vessel roughly comparable in size to the Battle-class, this turned out to be impossible and the design grew until it was larger than the Tristar-class, although still somewhat smaller than the Ikazuchi-class carriers. This growth meant that the Shimakaze-class would never be numerous enough to replace the many smaller vessels, but the design was eventually accepted as a more dedicated ship killer vessel meant to escort the Ikazuchi-class carriers.

The Shimakaze-class was designed with much of the modularity also used on the Garfish-class. The entire nose was designed as a bolt-on, stand-alone hull section, as was the lower central body section. This would have given the design an incredible flexibility, like the Garfish-class they were then still slated to replace. Similarly with the hull design, requirements were drawn up for armored cargo sections that could be delivered to planetary surfaces, but also beam and missile armed sections to gove the class more firepower when used as fleet cruisers.

However, in 2029 the second of the new cruisers, the Icarus, was stolen in the course of the Edwards rebellion. When the vessel was retaken, she mounted a new design nose section with a new type of cannon, almost as powerful as a reflex cannon, but faster firing, more reliable and less voluminous. In short order this nose section was analyzed and copied, then became the standard section for all Shimakaze-class vessels. A large protoculture detector is most commonly mounted on the cargo-attachment underneath the hull.

The Shimakaze-class has a hexagonal hull, with two outriggers that mount engines, hangars and sensor systems. The forward section of the hull is detachable but as explained above, under the current operational fitting, always contains a Synchro cannon. The lower aft part of the hull is open so that another specialised hull section can be attached there. The upper forward part of the fixed hull contains the heavy anti-ship cannons and the heavy missile launchers; underneath the missile magazine the Alpha hangars are located, with two quick-launch bays on each side of the hull. A command tower rises over the main hull, protected by the CIWS emplacements. The outriggers contain additional hangars for Beta fighters or other mecha, as well as additional sensor emplacements.

The proposed naming scheme for the Shimakaze class was for World War 2 era destroyers, a very numerous category of names which would have sufficed for the large production run envisioned for this class. Shimakaze class firing Synchro cannons


Although originally intended to replace three different ship classes and later to be the multi-purpose escort companion to the Ikazuchi-class carriers, the Shimakaze class turned out to be something of a white elephant during the attempts to dislodge the Invid from the Earth. Rather than with heavy warships, the Regis's Invid almost exclusively used massive suicide attacks from unarmed orbital carriers.

This made the existance of a ship class devoted to protect the carriers from heavy warships superflous. The Ikazuchi-class carriers were considered capable of dealing with this threat themselves more efficiently, on account fo their large number of defensive fighters, and their smaller but more numerous cannons, which were quite capable of dealing with the Invid Mollusk carriers.

As a consequence, production of the class was curtailed after the fifth unit, UES Scirocco. The sixth through tenth vessel had already been started, and the unfinished ships were stored near Tirol, but all other long-lead items were used for other ships or scrapped.

As related, the UES Icarus was stolen during the Edwards Rebellion. At that time the first of the class had not even been finished yet, but the basic design of the Shimakaze-class was proven in this conflict, when the UES Icarus destroyed the battleship UES Tokugawa with her new main cannon. The other ships of the class did not take part in this conflict, as they were still incomplete and the REF did not need to use unfinished ships to deal with the rebels. One consequence of this action though was the production of Synchro cannon forward modules for all Shimakaze class ships.

After the rebellion the nameship was completed and three more units entered service, typically serving as the escort squadron for the battlefortresses of the REF. During the final battle of the Third Robotech War, four of the five vessels of the class formed the Bombardment Group with the SDF-4 Liberator. The UES Icarus also gave sterling service in the first battles with Haydonite forces.
