The Trireme was a VTOL support vehicle designed to transport large formations of battle armor troops to back areas of combat zones.


Michaelson Heavy Industries' Trireme design won the bid for the newly formed Republic of the Sphere's RAF Quartermasters office requirement for battle armor transport.[1]

Equipment and Capabilities[edit]

Focused on its role as a transport, the vehicle dedicated much of its internal capacity to its cargo bay. The 36-ton cargo bay capacity allowed for the transport of two platoons of battle armor and supporting equipment, or an entire battalion's worth of battle armor alone. The troops exited the vehicle through the rear door of the VTOL.[1]

The craft was not intended for front line combat, so its hull was protected by only one ton of commercial armor. Its fusion engine allowed the craft to reach up to nearly 100 km/h, but was still considered slower than a typical VTOL transport of the era.[1]


  • Conventional Infantry Transport
    Geared towards movement of conventional Infantry, this variant had a simple reconfiguration of the Trireme's cargo hold in order to accommodate a company of infantry and its support equipment.[1] BV (2.0) = 132[2]
  • Combat Support (CS)
    A variant designed to help the design to cope with some combat threats, this model was noted for only having a cargo capacity reduced by half. The Trireme's engine was upgraded it to allow to handle additional armor and increasing of its speed to 118 km/h. It was also noted for the inclusion of paired SRM-2s and a Guardian ECM suite.[1] BV (2.0) = 417[3][4]
