I NTRODUCTION

Vehicles are an important part of any Traveller game, whether

to explore a new planet, deliver cargo or simply to get from

one destination to another. Different vehicles are required for

different tasks and this book presents you with almost 100

vehicles, from aircraft to watercraft and everything in between.

required. Aircraft listed here cover TL 2–8. Later ﬂ ying vehicles

use grav technology and are given their own section.

Grav Vehicles

Grav technology becomes available at TL 8. Worlds with this

technology quickly start to adapt most vehicles to use grav

drives for the versatility and speed they provide.

If you cannot ﬁ nd a vehicle here to suit your needs, you can

use the vehicle design rules to create your own. A blank vehicle

sheet is included at the back of the book that you can use to

design and record the vehicles you create. Although few civilian

vehicles are armed, a weapons section is included but for speciﬁ c

weapon details you will need the Central Supply Catalogue .

Hybrid Vehicles

Hybrid vehicles are those that have been designed to operate

over multiple types of terrain such as amphibious ATVs and sea

planes. Vehicles listed here cover TL 4–8.

Please note that some of the civilian vehicles listed in the

Traveller Core Rulebook have been included here, but using

the new design rules there are some minor differences between

them. You can of course still use the original vehicles but we

recommend that you use the versions listed here if you want full

compatibility with this and future books.

Land Vehicles

This section includes all tracked and wheeled vehicles that drive

along the ground. Vehicles are listed here for a wide range of

applications from TL 1–9.

Walkers

Walkers are land vehicles that move on legs, rather than

wheels or tracks. Civilian walkers are utility vehicles and range

from TL 8–10.

The vehicles detailed within this book cover a wide range of

Technology Levels and have been designed for speciﬁ c uses

and tasks. The vehicles are divided into the following sections:

Aircraft

The aircraft section details conventional ﬂ ying vehicles including

gliders, helicopters and planes. Most aircraft have a co–pilot

who can operate sensors, communications and weapons as

Watercraft

Boats and ships are used throughout the history of most worlds.

A number of vessels for travelling over and underwater are listed

here coving TL 1–9.

V EHICLE D ESIGN

C ONCEPTS & D EFINITIONS

By deﬁ nition, a vehicle needs some kind of motive power

(termed a Power Plant ) and a means to deliver this power

(termed a Drive System ) so the vehicle can move. Some kind

of control system is also necessary for the vehicle to be able to

function. This may or may not include a human operator.

• Right: The right hand side relative to a person inside the

vehicle facing forward.

• Left: The left hand side relative to a person inside the

vehicle facing forward.

Agility

A vehicle’s Agility is used as a DM to Drive and Pilot checks when

performing difﬁ cult manoeuvres as described on page 67 of the

Traveller Core Rulebook . Agility can also be applied as a –DM

to enemy attempts to hit the vehicle if it is attempting to dodge.

A vehicle doing so is treated as moving at maximum speed for

purposes of its own chance to hit an enemy. The vehicle’s drive

system will determine the Base Agility (see page 8) which can

be increased with accessories and design options.

A vehicle must have a Hull . This is the body of the vehicle and

includes the hull, axles, wings and other structural features as

well as the vehicle’s outer skin. Other Components are ﬁ tted

into the hull as required, which can include weapons, sensors,

communications equipment, crew facilities and cargo space.

Each component built into a vehicle takes up a certain amount

of space. The unit used in this design system is the cubic metre

(M 3 ). A vehicle cannot carry more than its internal volume

allows, unless it is an open structure with items piled up on top

or hanging out of the sides such as motorcycles, air/rafts and

ﬂ atbed trucks.

Agility modiﬁ cations add Agility Potential which is converted

into Agility during the ﬁ nal step of the vehicle design (see the

table on page 26 for details). Some vehicle types and design

choices can result in a negative Agility Potential which will give

a negative Agility score; a vehicle with negative Agility can be

given a zero or positive Agility with the right components.

A vehicle’s hull will have a Conﬁ guration, which is often

determined by its intended function. For example, a cargo van

will have a different conﬁ guration to an aircraft or submarine.

Speed

All vehicles have a Cruising Speed and a Top Speed (see page

26 for calculations). Cruising Speed is reasonably fuel–efﬁ cient

and comfortable. Top Speed is the maximum the vehicle can

manage under ideal conditions. Fuel consumption is doubled

when a vehicle is travelling faster than its Cruising Speed.

A vehicle’s hull will be constructed from whatever Material the

designer deems to be most suitable. Generally, higher–tech

materials will be stronger than lower–tech ones, allowing either

a tougher or cheaper vehicle to be built on the same general

conﬁ guration. The material a hull is built from also determines

the vehicle’s mass and Base Armour.

Ground vehicles also have an Offroad Speed (see page 26 for

calculations), which is the best speed they can achieve over

rough ground where there is no road. If the ground is very

rough, most vehicles can only crawl along or might not be able

to move at all.

Further design decisions are represented by additional

Qualities , which can modify vehicle attributes such as armour

and speed as well as providing seals and coatings.

The size, construction, conﬁ guration and qualities determine the

mass of a vehicle. Most components will also add to a vehicle’s

mass. Mass is used when calculating the speed of a vehicle.

Tech Level

Most design options and components have a listed Technology

Level, which is the lowest TL that the component is available.

The overall TL of a vehicle is usually determined by the highest

TL component used in the design. However, if a vehicle only

has a minimal amount of high–tech components you can give

the vehicle a lower TL if imported parts are available.

Facings

All vehicles have six facings as follows:

• Front: The normal direction of travel.

• Rear: The opposite direction to the front. Most vehicles can

also travel in this direction.

• Dorsal: The top surface when the vehicle is the right way

up in a gravity ﬁ eld.

• Ventral: The bottom surface when the vehicle is the right

way up under gravity.

Rounding

When designing vehicles some of the calculations can result in

fractional numbers. Where whole numbers are required, always

round up fractions unless otherwise stated. Also note that M 3

remains as a fractional number so no rounding is required.

1. Technology Level

a. Determine maximum Tech Level of the

vehicle.

This base value for capacity is termed Base M 3 and is used

to determine the cost of many components. Some vehicle

conﬁ gurations can modify the capacity of the vehicle; this

modiﬁ ed value is termed Total M 3 . Components that derive their

M 3 cost from the vehicle’s capacity always use the vehicle’s

Base M 3 value.

2. Capacity

a. Determine hull capacity in M 3 .

b. Calculate base Hull and Structure values.

The Example Vehicles Table indicates the typical size,

conﬁ guration and qualities of standard vehicles. These

examples are just guidelines and there is no reason why a

vehicle cannot be larger or smaller than those listed, or have

different qualities.

Hull and Structure

Once you have determined the vehicle’s Base M 3 you can

calculate the base Hull and Structure values. Hull and Structure

points are described on page 67 of the Traveller Core Rulebook

under ‘Vehicle Damage’.

To calculate the Hull and Structure points simply divide the

vehicle’s Base M 3 by four. Round the result down for the Hull

points and round up for the Structure points. These values can

be further modiﬁ ed by the material, conﬁ guration and qualities

(as detailed in Step Two). The minimum base amount for either

of these values is one.

S TEP O NE : C APACITY

Capacity is measured in cubic metres (abbreviated M 3 hereafter).

The shape taken by this volume is not relevant here. For large

components, the shape will be dictated by the shape of the

object. Smaller components or systems made up of many small

components, such as wiring or life support, can be any shape

and are usually dispersed throughout the vehicle.

C APACITY E XAMPLE

For our example, we will build a small armed van. Using the

example vehicles listed in the table we can see a van of this

size has a Base M 3 of 20 but let us make ours a little bigger

with 26 M 3 . We can now calculate the Hull and Structure by

dividing the M 3 by 4 as follows:

Capacity refers to the internal volume of the vehicle. 1 M 3

translates to 2/27 of a displacement ton (dTon) in the spacecraft

design system. However, the thickness of a vehicle’s hull and

external components, such as wheels, mean that a vehicle will

take up more space than its internal capacity. If it is necessary

to determine the overall displacement of a vehicle, calculate

displacement as 1 dTon for every 10 M 3 of internal volume the

vehicle has.

Base M 3 : 26

Base Hull: 26 ÷ 4 = 6.5 round down to 6

Base Structure: 26 ÷ 4 = 6.5 round up to 7
