Class Information

Forward section of a Class Y with a docked shuttle pod

The Class Y cargo ships were designed as a replacement to the older Class J Cargo Ships. These ships were operated under the authority of the Earth Cargo Service and like the other Earth based cargo ships the names of Class Y ships had the E.C.S. prefix. At the time of the launch of the first Class Y it was heralded as leap forward in Earth warp technology. These ships were quickly adopted and those who worked on a Class Y loved the ships citing their durability and ease of maintenance. While overall the ships were slightly slower a than the Class J Cargo Ships one of the major selling points of this class was it was designed to be up-gradable to the Warp 3 engine.

The hull of a Class Y Cargo Ship can be broken down into three main sections. These were the Forward Section, Central Spine and Cargo Modules. The Forward section housed the ships bridge, living quarters and the majority of the ships systems. The Central Spine provided access to the cargo modules and the warp warp nacelles maintenance access hatches. There were eight Cargo Modules with four on the port and four on the starboard side of the central spine. Each module was marked with illuminated numbers (1 through 4) in one corner of each module.

Aft end of a Class Y

The Class Y had a cursing speed of warp 1.5 and at this speed it would take a Class Y over a year to travel between Earth and Alpha Centauri. The ships twin warp nacelles were slung under the main hull of the ship at the aft end of the Central spine. The impulse engines were located on deck five of the froward section in engine pods that were mounted on the port and starboard of that deck. There were exterior flue tanks on connected to the forward section on deck four and were used to house the Deuterium and Anti-hydrogen fuel needed for the warp engine. The Y Class could operate at normal cruising speeds for up to 5 years before needing to refuel.

The Class Y was capable of defining itself with a single low yield particle cannon that was mounted on deck three and covered the forward firing arc. These ships were not equipped with any defensive systems such as hull polarization.

Other Notes


  • Mess Hall'


  • The Y class cargo ships were civilian craft operated by the United Earth Cargo Service and therefore had ECS before their name.
  • The Y class ships could be equipped with a warp 3 engine if the ships owner could afford the cost of the upgrade.
  • The Y class cargo ships were known to make runs of up to 5 years without the need to refuel
