T5 Only: Spearhead Class Fast Modular Transport

[agorski]

Introduction

Since I’ve never really done deck plans for a ship before, I have a new-found respect for the amount of preparation and work involved.

I decided to design a ship using T5.10 rules. Since I’ve created the Adventure Class Ships for iOS app, I wanted to eat my own dog food. The ship I designed takes advantage of the fact that T5.10 allows for multiple hulls in a ship design, and my app calculates drive performance as I change the number of hulls. More on this later.

I chose Omnigraffle Pro for the Mac to do the deck plans. It took a while to create the stencils for all the deck plan symbols I used and to get used to the app.

While doing this I discovered that the process is somewhat iterative. T5.10 defines the size of ship components in tons, which is easily convertible to deck squares. After designing the ship and starting to draw the deck plan, I went back to the design and modified how big certain compartments should be. For example, a wardroom for the officers. There’s a certain amount of handwavium required as passageways are assumed as part of the component tonnage.

Ship Description

The Spearhead Class Fast Modular Transport is a TL 14 400 ton naval auxiliary designed for independent operations rather than regular fleet or base supply. It is favored for special operations missions.

The ship has 2 decks. The upper deck has a bridge and officer/NCO quarters forward. The lower deck has enlisted quarters, medical and operations spaces, and 2 personnel air locks forward, a 2 deck high spinal cargo hold in the middle, and a 2 deck high drive room aft with fuel tankage and 2 personnel air locks.

The streamlined main hull of 400 tons has docking connectors for up to 8 2 deck high 20 ton modules, which can increase the total tonnage to 560. Each connection point includes a grapple and connections for various ship-supplied services as required by the module type, including a personnel hatch and a cargo hatch. Modules connect along the spinal cargo hold of the main hull, which includes a large cargo lock that opens ventrally.

The ship has no external docking grapples so module change-out is performed on a planetary surface or in a large orbital naval base hangar.

Drives are up-rated to accommodate the possible increased tonnage. The Power Plant is also larger than normal to service power requirements of the modules. Life Support is also up-rated to accommodate passenger and troop module requirements.

Being a naval vessel rather than a commercial transport, it includes a larger crew, better weaponry and defenses, and more sensors. Components use Dispersed Power where applicable. Weaponry is focused on defense.

Performance

Although the app will show how drive potential changes as ship tonnage changes, I found it easier to create a spreadsheet to analyze this, using the same formulas used in the app.

This table shows the effect of adding fuel modules only to the ship. Each fuel module adds 19 tons of fuel. You don’t necessarily get that much bang for the buck as the total ship tonnage increases with each module added.

Here’s the details of the design exported from the app, edited for improved readability:

FMT (Spearhead Class Fast Modular Transport)
TL-14 MCr173.84 Tons: 400
...

Light on life support? 2 Dt is long term for 10 people or short term for 20 people, a bit light for the crew of 21 and even less for passengers?

Light on Control Consoles? Consoles can unfortunately malfunction, with only one Control Console on the bridge the ship would be difficult to manoeuvre if the only piloting capable console malfunctioned? Same for gunnery?

Lots of consoles? With 17 consoles for 21 (28?) panels you are quite a bit over what is needed for Ergonomics=2, which is 11 (or perhaps 15?) spacious consoles.

Crew Quarters are very tight at Comfort=1.7?

Transfer Pump would be useful to use fuel in pods?

Crew has very many chieftains and very few indians with 9 officers, 9 POs, and 3 ratings?


Deck plan:

It's difficult to see without square grid, but access-ways and corridors does not seem to have any allocated tonnage? It should presumably be part of "Common Area" as it notes "For movement and recreation". CT specifically noted that corridors was included in crew quarter tonnage. (Yes, it's a pita, as you need a lot of corridors to make a functional ship.)

The only way to access engineering spaces it through the cargo hold?

Sorry, I don't understand.
Acceleration should never be more than 3 G? (4 G at 400 Dt would req. 800 EP M-drive?)
J-3 should not be possible with 4 pods (req. 720 EP), unless they are drop tanks (necessitating Transfer Pumps)?

 

[agorski]

Light on life support? 2 Dt is long term for 10 people or short term for 20 people, a bit light for the crew of 21 and even less for passengers?

It's a single Long Term Life Support rated at 1200 person-days. Adequate for most cases, but not enough for a troop transport configuration. In which case I would replace the Armory in the Troop Module with life support. Adding additional to the ship would probably be wise.

Light on Control Consoles? Consoles can unfortunately malfunction, with only one Control Console on the bridge the ship would be difficult to manoeuvre if the only piloting capable console malfunctioned? Same for gunnery?

Good point. But it's a transport, not a warship. ;-) I would think you could pilot with an operating console at a disadvantage.

Lots of consoles? With 17 consoles for 21 (28?) panels you are quite a bit over what is needed for Ergonomics=2, which is 11 (or perhaps 15?) spacious consoles.

I wasn't shooting for a specific target. Just noted that the 400 ton Daring class example has 19 consoles.

Transfer Pump would be useful to use fuel in pods?

I thought about this, but it looks like the transfer pump is intended for uber-quick transfer of fuel from drop tanks, so I just made an assumption that the implied pumps in the system were adequate.

Crew has very many chieftains and very few indians with 9 officers, 9 POs, and 3 ratings?

I assume ranks R1-R3 are ratings, ranks R4-R6 are NCOs. So R3 Petty Officer Second is a rating for 9 officers, 4 POs, 8 ratings.

Deck plan:

It's difficult to see without square grid, but access-ways and corridors does not seem to have any allocated tonnage? It should presumably be part of "Common Area" as it notes "For movement and recreation". CT specifically noted that corridors was included in crew quarter tonnage. (Yes, it's a pita, as you need a lot of corridors to make a functional ship.)

Omnigraffle actually prints out the 1.5 meter grid, but unfortunately it's dim and you have to look close to see it. As I mentioned at the beginning above, I've adjusted the space used by things downward to try to account for all the passageways. But I'm not rigorous about it. Handwavium.

The only way to access engineering spaces it through the cargo hold?

Well, there's always EVA. ;-)

Acceleration should never be more than 3 G? (4 G at 400 Dt would req. 800 EP M-drive?)
J-3 should not be possible with 4 pods (req. 720 EP), unless they are drop tanks (necessitating Transfer Pumps)?

Don't know what to tell you. I just cranked through the formulas taking into account the Stage efficiency.

 

[AnotherDilbert]

It's a single Long Term Life Support rated at 1200 person-days. Adequate for most cases, but not enough for a troop transport configuration.

I'm perhaps a bit dogmatic, but I use the T5.09 definition, so Long Term Life Support is 120 days for 10 persons. The hint is in the name "Long Term", it's life support for a long time, not for more people.

If I were Referee the ship would face penalties for insufficient life support...

Good point. But it's a transport, not a warship. ;-) I would think you could pilot with an operating console at a disadvantage.

I always allocate two pilot consoles, just like a current airliner. The extra cost is negligible for a bit of extra robustness.

It would fit the bridge you drew if the two front-most consoles were pilot and co-pilot consoles.

I wasn't shooting for a specific target. Just noted that the 400 ton Daring class example has 19 consoles.

Size have nothing to do with number of consoles; a 1000 Dt ship with the same equipment would need the same amount of consoles.

The Daring is, if not military, at least a fighting ship, not just a glorified truck.

Omnigraffle actually prints out the 1.5 meter grid, but unfortunately it's dim and you have to look close to see it.

OK, if I magnify I can see it. That was very faint...




I believe you have calculated cost and panels without pods and hence without the grapples for the pods. It should be another 7 panels and MCr 7-8?

You have about 10 Dt undertonnage, should probably be noted somewhere?

 

[AnotherDilbert]

Don't know what to tell you. I just cranked through the formulas taking into account the Stage efficiency.

I believe you used Stage effect twice:

With one pod: 420 Dt

M Drive E: 500 EP
Stage Ultimate, effect 130%
Effective EP = 500 × 130% = 650 EP.

Drive potential = 650 EP / 420 Dt × 2 = 3.09, rounded to 3.


You calculated potential = 500 EP × 130% / 420 Dt × 2 × 130% = 4.02, rounded to 4?

 

[AnotherDilbert]

Ling-Standard Products is proud to present its proposal to the IN RFP#34C345: the Spearshaft class Light Modular Transport system.

Overview:

The core hull is 300 Dt and it can carry up to three 100 Dt subhulls and two 30 Dt pods. Performance is J-4 & 4 G at 330 Dt, J-3 & 3 G at 440 Dt, and J-2 & 2 G at 660 Dt. No cargo is carried internally, all payload is external in the pods. A maximum of 340 Dt cargo can be carried.

100 Dt subhulls come with full hardpoints and allow us to build much more capable modules, e.g. with light ortillery bays. (And saves on grapples and control panels, hence needed consoles.)

Core Hull:
Using a 300 Dton streamlined hull, it has a J Drive F, a M Drive C2, and a P Plant C2 giving performance of jump-4 and 4 g acceleration. There is fuel tankage of 130,68 Dton, enough for 4 weeks and 1 jump-4.
Controls consists of five control consoles, ten operating consoles, a m/3/bis computer, and a m/1/bis computer with Ergonomics 2.
There are six sensors: a communicator, an EMS, a scope, a neutrino sensor, a grav sensor, and a stealth mask.
Crew accomodations consists of a large stateroom and eleven staterooms with a Comfort of 4.
There are three weapons: a triple missile turret, a triple beam laser turret, and a triple sandcaster turret. There is a screen: a nuclear damper.
Cargo capacity is 10 Dton. The ship requires a crew of twelve: a pilot, an astrogator, two sensor ops, three engineers, an operations, a medic, two gunners, and a screen ops. The ship costs MCr 135,4.

A default 100 Dt subhull has 95 Dt free and costs MCr 13.
A default 30 Dt pod has 27 Dt free and costs MCr 5.

Projected normal configurations:
J-2: Core Hull + 3 × 100 Dt pod + 2 × 30 Dt pod
J-3: Core Hull + 100 Dt Pod + 30 Dt pod
J-4: Core Hull + 30 Dt pod


Details:

Wherever possible civilian certified components have been used to save cost and development time, and ease maintenance and repair. The ship is built at TL-14 (with an imported TL-15 jump drive). The pods can be built at lower TL yards.

For added resilience an extra layer of armour and dual power plants and M-drives nexused together are used. The extra layer of armour is concentrated over vital parts of the hull, leaving e.g. the fuel lightly protected.

To adhere to standard naval refuelling requirements, the ship is streamlined and equipped for gas giant skimming and water landing and refuelling. A fully airframed hull gives decent stability and allows airstrip and wilderness landings.

The crew quarters are large and comfortable for the nominal crew of 12, but can handle up to 24, if needed, with long term life support (four months).

The bridge is large by civilian standards, but small by naval standards. Still it can handle the ship's systems (with some overcapacity) with a reasonable level or Ergonomics (2). The bridge can control an additional 4 panels with maintained ergonomics. All consoles have basic brains, and can maintain routine operations without manning. In principle a skeleton crew can fly the ship.

Crewing is envisioned at 12: One full watch of bridge, engineering, and gunnery crew, and a minimal ops crew. Two junior officers, a CPO, three POs, and 6 ratings. For example:
Bridge: Pilot Officer/Captain, Astrogation Officer, Sensor PO, Sensor rating.
Engineering: CPO, rating, rating.
Service: Ops PO, Medic rating.
Gunnery: PO, rating, rating.

This allows all important consoles to be manned at Action Stations, and a minimal bridge, engineering, and gunnery watch at all times.

The ship has a minimal default weapon load-out of one turret and two small point defence mounts, leaving one hardpoint and one firmpoint free with 2.5 Dt reserved. Additional weapons can be mounted in the pods and operated from the bridge.
