The Prometheus Combat Support Bridgelayer (also known as the Prometheus CSB) is a Federated Suns Combat Support Vehicle used to assist conventional ground vehicles traverse tough terrain and downed bridges. The vehicle was first designed by the Olympus Construction Vehicles of Fallon II in 2471. The Armed Forces of the Federated Suns was in need of a vehicle that could help its extensive conventional forces keep up with their BattleMechs' all-terrain abilities.[1]

Once in service, the Prometheus was put into use to overcome battlefield difficulties for the troops, such as destruction of fortifications and clearing minefields.[1]


The AFFS deployed the vehicle with its forces during the last years of the Age of War, trying to help conventional vehicles compete with the BattleMechs of the era.[1]

The vehicle was viewed by combatants as an inferior tank, and was never targeted by either frontline forces or conventional infantry. This allowed the vehicle to remain in service despite its factory having been destroyed in the First Succession War by House Kurita. A few of these even survived well into the late thirty-first century. By the Jihad, demand for the vehicle had resurfaced because FedSun forces were rebuilding after the bloody FedCom Civil War. Production resumed with the return of Olympus as its main manufacturing company.[1]

All AFFS RCT formations during the Jihad had least one Prometheus CSB attached to them.[1]

Weapons and Equipment[edit]

The vehicle’s main equipment is its two side mounted Heavy Bridgelayers, one per vehicle's flank. Vehicle bridges each produce span of 30 meters each, able to handle vehicle or 'Mech traffic up to 90 tons. The vehicle has a five ton infantry compartment which allows it to carry a platoon’s worth of troops, typically combat engineers.[1]

For the vehicle's defense, it is armed with a 15-Tubed Long Range Missile Launcher mounted in its front. Meant as a stand-off weapon only, the vehicle is only given one ton of ammunition for it. Also mounted in the front is a Medium Laser. These weapons are linked to an Advanced Fire Control which enables the vehicle to fire with military precision. Prometheus has small five ton cargo capacity, with a door mounted in the rear.[1]

The Prometheus has ten tons of BAR 10 grade armor protecting its hull from damage.[1]


The vehicle features an armored chassis and control modifications. As of this revision, there are no published record sheets for the vehicle.[1]
