The H5 Oliphaunt is a third generation Gaellician-Seylosian main battle tank designed and produced as a private venture by MacNamera Heavy Industries. The name Oliphaunt is a nod to the preceding H Series Tanks, as well as a tribute to Aexamenid history and mythology.

History

Following the success of the H3 tank, the defense design division of MacNamera Heavy Industries began work on a new H series tank variant. A future need for a more heavily armed tank was anticipated leading to the beginning of design work in 1976 as a private venture. Initially the design began as a variant of the H3, the most significant changes being the addition of improved armor on the turret face, and the replacement of the H3's 105mm gun with an 120mm rifled gun. Additional 120mm armed H3 variants were iterated upon but all remained confined to paper.

In 1978, work began on a fresh H series tank. The new tank would utilize the same hull and chassis as the H3, but the turret would be an entirely new design. The turret consisted of a welded steel design, with appliqué armor plates. The design also incorporated Explosive reactive armour on the tank hull.

Design

In the tradition of other H Series tanks, the Oliphaunt was designed from the start with an emphasis on reliability and maneuverability. In hopes of expanding the market of the tank, features that would make the tank competitive with heavily industrialized peer nations were also a consideration. Significant resources were expended to incorporate state of the art armor, and fire control systems. At the time of production in the late 1980s, the Oliphaunt was one of the most innovative tank designs in the wurld without excessively increasing cost.

Electronics

Due to relations between Gaellicia and Tagmatium at the time of development, the variant of the Oliphaunt operated by the Ríogan Army is fitted with significantly different electronic equipment and software than other versions of the tank.
