Below is my most recent design. I built it myself (Look of Proud Kid with Lego). I used Visio and some stencils I found online and in the program itself. The operating stats for the ship are from GUPRS Interstellar Wars ship design rules. I will post the spreadsheet for those some time soon. In a nut shell she is
150 Dtons
Jump 2 with 30 Dtons fuel
Refines full fuel load in 19 hours
3.25 Gs thrust empty
2 Gs thrust loaded
1 Triple Turret and Hardpoint (I dispersed them in the plan but they are accounted for in the design and the plan)
1 Pulse Laser
1 Missile Launcher
1 Sandcaster
Scan 19 sensors (read as Good+ sensors for other Traveller universes - Better than a merchant, not as good as a Ship of the Line.)
Standard bridge
6 Standard Staterooms
2 (Yes that's correct, two) Modular Cutter Bays holding 30 Dtons each of modules. That is a total of 60 Dtons available for mission load outs.
The hull is an Airframe with Stealth
Price is (IIRC 85 MCr New)
7 Dtons cargo hold
1 MW power shortfall (so you can't run the fuel plant and the pulse laser at the same time. Fuel up and filter before you have to run)
The final design is approx 157 Dtons which is within 5% of projected so not to shabby.
Starting from the bridge, which is upper deck, forward there is 4 acceleration couches on the bridge, going clockwise from the bridge iris valve, at 1 o'clock is the co-pilot seat, at 3 o'clock is the commo/sensor ops, at 9 o'clock is the enclosed gunner station (holo projection surround screens) and at 11 o'clock is the pilot seat.
Aft are the crew staterooms, with the foremost port stateroom being a single bunk for the Captain. The others are all double bunk as needed. Each stateroom has a fresher.
There is a lift shaft which can be sealed to the lower deck.
Aft of this is the upper Sandcaster emitter and control array. This covers the upper arc of the ship.
Aft is Cutter Module Bay 1
The between module bay space is a through passage and airlock. This airlock opens overhead and has a docking ring array to lock onto craft and space-stations above the ship.
Port and starboard are the missile launch arrays. They are accessible from the access panels and outside. Loading is done on the ground from the outside. You could load them from within the ship, but it is difficult and can only be done slowly (IMHO no more than one missile per combat turn, it would need a minimum of two crew members and that crew would be taken away from any other duties; e.g. Damage Control, Engineering, Gunnery, etc.)
Aft of that is Cutter Module Bay 2
Aft of that is the upper engineering deck, which is catwalked and open grating to below. This deck mounts the maneuver drives and the engineer's station dead aft. It also has a work bench to starboard and forward in this compartment.
Below this is the lower deck engineering space. This space contains another work bench, the Jump drive, the Power plant, the fuel purification plant and a small airlock aft and portside.
Port and starboard are the fuel tanks, the inlet valves and plumbing for fuel and the wing root sensors.
Forward is the lower part of Cutter Module Bay 2.
Forward of that is the lower pass through and the pulse laser arrays. IMTU the pulse laser uses 8 emitter arrays, on laser periscopes, which collimate on distant targets. This airlock opens through the deck below and has a docking ring array to lock onto craft and space-stations below the ship.
Forward of that is the lower part of Cutter Module Bay 1.
Forward of this is the lower Sandcaster emitter and control array. This covers the lower arc of the ship.
Forward of that is the main crew/passenger airlock on the starboard side, the ships locker and main safe on the port side. This area contains the lower part of the lift shaft.
Forward of that is the ship's cargo bay, which opens both port and starboard.
Forward of that is the galley and work space. It even has a washer and dryer and work space for folding clothes. The galley has 2, refrigerators, 2 microwaves, 2 dishwashers, a garbage compactor, a range with 4 burners and a griddle, a coffee maker and water cooler, a built in oven and lots of shelf and counter space.
Forward of this is the crew lounge. Clockwise from the iris valve is the repeater monitors at 12 o'clock, the multi-machine exercise device at 2 o'clock, a multi option video machine at 2:30, the wardroom table at 3 o'clock, the couches and recliner at 9 o'clock to 11 o'clock.
Depicted in the crew lounge, to scale, are foremost a geneered Ursa, middle is a human, aft is a geneered marsupial/primate/rodent. All three are crew members.
Forward of that is the main sensor emitter and receiver array. A smaller array is above this in the bridge space.
