The Observation Dome is a small retreat deck featuring a sofa, coffee table, and a minimal bar with an entertainment center. An optional Laser Battery system can be installed on this deck in lieu of the luxury items. This penalizes performance by a factor of one to either the ADF or MR (owner’s choice) as well as a cargo reduction of one unit. A four function point program must also be uploaded to the mainframe computer. 

The Bridge level contains all the operational stations for the ship. The helm is to port (right side of the map) with captain/pilot and co-pilot positions, an engineer’s station is to starboard (left side of the map) and the astrogator station is adjacent to far starboard. All three stations have a computer panel. The mainframe computer is nestled under the deck on the ventral side, accessible via the floor panel that leads to a maintenance shaft running all the way down to another panel in the ceiling of the Crew Deck. 

The Crew Deck is a larger area with three cabins and a common area with galley and entertainment. The double occupancy Captain’s Suite Is to port, although it is typically single occupancy barring any “special” crew relations the captain may have. A pair of convertible cabins is to starboard, each featuring one to three stacked bunks depending upon crew size. A docking collar outside the airlock can accommodate a lifeboat or launch. 

The Maintenance Deck is the lowest deck on the ship and features monitoring equipment for the drives at dorsal/starboard, accessways to the engines themselves, life support equipment to starboard, a recharging station for robots & power packs adjacent to the elevator, a tool & machine shop to port, and a generator & power relay station at ventral/port. Floor panels can be removed to access equipment descending further into the hull. A single workpod is nestled between the drives. 

A sturdy rail system extends aft of the spacecraft to which standardized cargo containers can be affixed. One to five cargo unit capacity containers can be affixed to this rail system, totaling the cargo capacity of the ship itself (five if standard, four if a laser battery was added). Containers can be quickly offloaded and replaced on dedicated routes, although when operating independently there is no guarantee that loaded containers will be awaiting tramp freighters...as such an independently owned TT-500F will tend to keep the largest container mounted.
