DFIG Harvester

Designed and built in the early to mid 2300s on a custom order basis at the DFIG operated Vega Shipyards facility in orbit of Vega VII Moon 3 [1] and other facilities, the "Harvester Class Resource Collection Rig" was a stand alone mobile facility for ore extraction and processing. There is space on board for housing of a crew of twenty, and docking for cargo lifters to remove the product to market or final refinement.
One might ask "Why build a mining rig in a shipyard?" The answer becomes obvious only when seeing the "Harvester" in person. As the "Harvester" is approximately the size of a bulk freighter, and has independent lift and flight characteristics it was required to be registered with the local cargo authority as a starship and given a transponder code chain. While not a warp capable craft, it is more than capable of moving job sites from one moon to another within a star system, though relatively slowly.
===Power Systems=== 
*The Harvester is powered by a fusion power impulse reactor
*Power is distributed via an EPS Grid identical to starships standard circa 2300
*Battery power is distributed via a secondary grid
=== Engines===
*Lift / Transit
**Impulse power is redirected through driver coils for vectored thrust, allowing for controlled decent or ascent from planetary bodies no more than 7.3g
**Power Demand 100% at 7.3g, 10% at 1g
**Lift systems are orbital and system grade impulse travel
*Ground Transport
**Impulse power is redirected through turbines for crawler thrust, allowing for movement speeds of up to 30kph over relatively level ground
**Power Demand 15% at 1g
*Anti-Grav Hover Systems
**Impulse power is redirected to the AG field generators to allow for a lift of up to 60m, and movement speeds of up to 100kph
**Power Demand 30% at 1g
===Harvesting===
*Dismantler
**Impulse power is redirected through the Dismantler, a combination of energy weapon and replicator technology designed to not destroy valuable materials while vaporizing chaff
**Power Demand 10-50%
*Accumulator
**Impulse power is redirected through the Accumulator in order to collect material for processing through a combination of transporter and tractor beam technology
**Power Demand 10-50%
===Processing===
* Refining
**Impulse power is routed through the Refiner to process collected material, and unlike other powered systems does not deplete energy at the same rate
**Power Demand 1-20% at 1g [2]
===Docking===
*Offloading 
**May be accomplished via a manual chute type offloading, much like the ejector used for material not used
**May be accomplished via a dual docking port on the dorsa of the Harvester
***The DFIG standardized docking contains a Personnel/Umbilical port, and a materials offloading port
===Interstellar Transport===
The "Harvester" is designed to lift itself into orbit or to push itself to new job locations, but when Faster Than Light travel is required, the Vega Shipyards Hercules Class Warp Tug is the preferred method. As the two were designed by the same team to be compatible, there is little guesswork involved.
In all, 39 "Harvester" craft were built at the Vega facility prior to 2400, with 15 of them for use right in the Vega system. Variants using tracked motivators, anti-gravity and pontoons had all been built. More than 1500 additional examples of the class are in operation as of 2427, constructed either at the Titan Orbital Shipyards DFIG Facility, or by license at other shipyards both within and outside of the UFP borders.
