The Tachyon class Light Trader is a civilian vessel. It is a commercial transport typically encountered operating within clusters of stars within the Distant Fringe region. It is classified as a merchant vessel and is constructed as an X-Range design. Similar designs have been in use from the time the Distant Fringe was first settled.
General Description & Deck Plans
The Tachyon class is an airframe flattened sphere with a mean diameter of 21 meters and a mean height of 5.5 meters, with paired lateral drive housings slightly increasing the overall length and the width of the stern (with their position indicated by a shaded area on the diagram below). The slightly irregular shape of the hull increases the overall internal space, giving the ship a total enclosed volume of approximately 1,350 cubic meters. There are two decks. The machinery and fuel tanks are located aft and operations are run from a small engineering control room. The lower deck is given over to the cargo hold: an area towards the rear of the hold, positioned below the accommodations section, is set aside as a vehicle hangar. The central section of the upper deck is given over to Staterooms and the turret mountings, while the bridge, computer and electronics are located forward.
- A common variant of the design is the Liz Zhorka class Light Trader.

Basic Ship Characteristics
Following the Imperial Navy and IISS Universal Ship Profile and data, additional information is presented in the format shown here. The small craft factor indicates the number of squadrons (of ten subcraft) carried on the ship. Tonnage on the universal ship profile is shown in kilotons (thousands of tons) where necessary. 
|Basic Ship Characteristics |
|1.||Tonnage / Hull||The Tachyon class is constructed using a 100 Ton hull built in a fattened sphere configuration. The hull is an airframe shape, giving good atmospheric performance that is further enhanced by airfoil surfaces and the vessels onboard gravitic systems.|
|2.||Crew||Total Crew Complement: 3
|3.||Performance / Engineering||The vessel mounts a DeVoss-type Jump-1 drive, a Maneuver-1 drive and a Power Plant-1, giving performance of Jump-1 and 1-G acceleration and producing 1 Energy Point. The ship has an agility rating of 1. The dedicated internal fuel tankage is sufficient for one jump-1 and gives the power plant 4 weeks duration.
|4.||Main Section / Electronics||Adjacent to the bridge is a Model/1 Computer: the ship does not have a backup computer.|
|6.||Armament / Weaponry||The normal fit-out for a Tachyon class is a single mixed triple turret:|
|7.||Defenses||The hull is unarmored.
The vessel is not fitted with screens or other passive defensive systems.
|8.||Craft / Subcraft||Vehicles|
|9.||Fuel Treatment||The vessel has internal fuel tankage of 11 dTons.|
|10.||Cost||The basic cost of the vessel, complete with its Air/Raft, is MCr35.478.|
|11.||Construction Time||40 weeks (10 months) as standard.
|12.||Remarks||Standard cargo capacity amounts to 40 dTons.|
The Tachyon class is a small merchant designed to carry incidental consignments of cargo. The design is considered underpowered and suffers performance issues in high gravity environments. It is representative and a large number of variants exist, particularly with regard to the allotted weapons systems, onboard electronics, and the fit out of internal spaces. The current design dates to the Golden Age, but many elements are reused and aspects of the layout and construction indicate that the vessel has Vilani origins.
Tachyon class Traders are sometimes referred to as "puffers", a reference to small coastal watercraft serving isolated communities on pre-spaceflight Terra. The name has romantic connotations, implying personal freedom and a simpler way of life, but also reflects the rather claustrophobic conditions aboard those ancient trading vessels. The interior of the vessel is relatively cramped and the class are known for the substandard quality of their life support and environmental systems.
Distant Fringe Vessels
The Distant Fringe is said to be a far spinward-rimward area inhabited by colonists and refugees originating on Terra. The region is extremely isolated, separated from the rest of Charted Space by vast, almost uncrossable rifts that were once broached by a system of calibration Points and the use of tankers. Those few academics within Charted Space who have found references to the Distant Fringe regard it as little more than a tall tale. Likewise, many of the inhabitants of the Distant Fringe believe the existence of Charted Space to be mythical.
Vessels originating within the Distant Fringe are very rarely encountered outside of the region. However, misjumps do occur and anomalies with bizarre spacetime and Jumpspace effects exist: as such, craft of this type are not entirely unknown within Charted Space.
Class Naming Practice/s & Peculiarities
A number of companies manufacture ships equivalent to the Tachyon class. They vary in hull shape and internal layout but all share the same basic design and all have very similar capabilities and performance characteristics.
- Each variant class is named by the company that produces it: these organizations generally draw on traditional naming protocols. It is not uncommon for a historical class name to be reused.
- Individual vessels within a class are issued specific serial numbers and transponder codes but traditionally are named by their first crew. This is considered a serious affair and a ship with a frivolous name is considered "unlucky".
