The Trireme is a VTOL Support vehicle designed to transport large formations of Battle Armor troops to back areas of combat zones. Michaelson Heavy Industries' design won the bid for the newly formed Republic of the Sphere's RAF Quartermasters office need for Battle Armor transport.[1]

Equipment and Capabilities[edit]

Focused on its role as a Transport, the vehicle dedicates much of its transport capacity to its cargo bay. The 36 ton Cargo Bay capacity allows for the transport of 2 Platoons of Battle Armor and supporting equipment, or an entire Battalion worth of Battle Armor. The troops exit the vehicle would depart through the rear door of the VTOL.[1]

The craft is not intended for front line combat, so its hull is protected by only one ton of Commercial Armor. Its Fusion Engine allows the craft to reach up to nearly 100 kilometers per-hour, but it is still considered slower than a typical VTOL transport of the era.[1]


  • Conventional Infantry Transport 
    Geared towards movement of conventional Infantry, this variant is a simple reconfiguration of the Trireme's cargo hold 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 is noted only having a cargo capacity reduced in half. The Trireme's engine is upgraded it to allow to handle additional armor and increasing of its speed to 120 km/h. It is also noted for inclusion of paired SRM-2s and a Guardian ECM Suite[1]. BV(2.0)=417[3][4]
