[ST] Sprite-class deckplans

For as long as I can remember I've been fascinated by blueprints and especially deckplans, so I've finally taken the plunge and tried to make a few myself.

So, to get a feel for things I started with a very simple ship design of my own, with a minimum of odd corners to fill or canon baggage to keep in mind. I give you, the Sprite-class medium-range cargo hauler : Linky

She's a pre-TNG successor to ships like the J-and Y-classes. Cargo containers are hooked up to the aft end (just like on a J), although the ship can also be used as a small passenger craft without them. She's about 30-ish meters long (that is, based on the deck heights I aimed for 30m but she might've ballooned a bit), with a crew of 13 and room for 16 passengers.

Some notes :

* The nacelles are placeholders until I learn how to draw nacelles. Expect the finished product to be a bit beefier; the placeholders look like they'll snap off.

* The black strips on the bridge dome are Type-IV phasers. They're really more for show then for actual combat; it's not like you'll be doing much fighting in a glorified semi.

* On the cross-section, the turbolift shaft is yellow, the Jeffries tubes are green, the corridors are blue, and some of the machinery is dark-grey.

* Each deck has a clear height of 3m. The between-deck spaces are 1m high and hold service tunnels, conduits, gravplating and structural elements, except the space underneath the lowest deck which also holds the antimatter bottles for ease of ejectability.

* She's not pretty, but she's not supposed to be either. The Norkova and Jenolen were fat, too.

A-deck

One bit of corridor to tie everything together. The bridge is very cramped and clumsy, mainly because that's what TNG-era bridges tended to be. There's four stations (OPS, CONN, captain and an engineering station in the back) but don't expect more then three people to be on the bridge at any time. The Jeffries tube (green) is accessed by crawling through the subspace radio equipment (...might want to change that)

B-deck

All passenger quarters have two beds and a bathroom with a toilet, sink and sonic shower (here depicted by...a diagonal line). The staircase runs from B to C-deck since those are the only decks accesible to passengers, leaving the turbolift for the crew. The mess has large overhead windows and a locker with various boardgames - hey, it worked for the crew of the E-D.

In case of a catastrophic replicator system breakdown, the ship carries emergency rations for two weeks or until the crew kill themselves rather then eat another emergency ration, whichever comes first.

C-deck

Image

C-deck has a spectacular lounge in the bow, with floor-to-floor windows giving a clear view of what the ship is about to fly past/through. The four lifeboats each carry 12 people, although the heavier passengers may have some difficulty getting into them - let's call it a "Darwinian escape system". The communications access room has four computer terminals that are tied into the various subspace communications networks and databases. The crew quarters come in 2 sizes : officer's quarters are a smaller version of the passenger rooms, while the rest of the crew share their quarters with three others, their bathroom with six, and their toilet with 12 (that is, both pairs of three-bed quarters share a communal bathroom - applause pelase for the versatile "diagional line" - with a shower and sink but no toilet; greasemonkeys go potty down the hall).

The umbilical in the back leads into the cargo containers attached to the back of the ship, with a one-person airlock off to the side.

Both lounges and the crew mess have their own replicator terminal.

D-deck

Image

D-deck is the main engineering level. Apart from various self-explanatory machinery, it also has a small brig and security office/weapons locker (neither of which is used under normal circumstances). The emergency bridge has a CONN/OPS station, engineering controls and a fourth console for the captain. The deuterium bottles feed both the warp core through a ceiling conduit and the impulse reactors below. The crescent-shaped doodads attached to various walls are computer consoles; the round thingy right above the warp core is a one-person lift to the bottom engineering level.

Waste reclamation takes the contents of the plumbing system and recycles it into pastries and the water you brush your teeth with. Yay for the future, I guess.

E-deck

Image

Known in ancient times as "the basement". The cargo hold holds the passenger's belongings (hah ! You thought it'd hold cargo...) as well as raw materials for the replicators and whatever else is needed on a three-week trip (probably alcohol). If the turbolift breaks down it can be lowered onto E-deck for repairs; the maintenace bay is right next to an all-purpose engineering workshop. Impulse engineering holds the engines themselves and the fusion reactor.

Pretty nice, but I'm not sure about the placement of the engine nacelles. Is there something really heavy on the bottom deck that weighs half as much as the rest of the ship?

Overall, she looks like a lovely little 'House Ship' or spacegoing RV for people not interested in cargo hauling. Perhaps you can keep a modified version of the 'small' nacelles for a dedicated Homeship model? I also recommend you attach a small aeroshuttle to the bottom via a docking collar or alcove buried in the bottom of the hull if the ship isn't meant for planetfall. Keep in mind that if you add a deck to the bottom for the shuttle it solves the problem of the warp 'thrust lines' not appearing to go through the CoG.

I also recommend a third impulse engine above the top deck (not a great idea due to the large mess hall there) or move the two existing ones to just above the warp engine strut attachment points.


Overall, an excellent starting design, but it can use a few refinements. :)

Third Rule of Starfleet Ship Design :
Warp nacelles must have at least 50% line-of-sight on each other across the hull.
That means I could either have the nacelles stick out on top or below - I took "below" because that'd keep them closest to the lower decks that hold the warp core and fuel tanks.

(Well, you don't have to follow the rules, especially when a lot of canon ships don't, but I still think they're good guidelines).

Besides, it's the same setup as on the J-class freighters this thing is supposed to replace.
I also recommend a third impulse engine above the top deck (not a great idea due to the large mess hall there) or move the two existing ones to just above the warp engine strut attachment points.
Then they'd be blasting straight into the cargo containers :wink:

New nacelles !

Nice and beefy looking. Do they have a dual-tandem warp coil arrangement like Galaxy nacelles?

They just make things go :)

I really didn't think about that; they're just a smaller version of the stock early-TNG nacelles.

Oh ok. Just wondering.
