Operating Difficulties and Loading Problems
Q. Why can't I install the game to my hard disk?
1. You must check all system requirements, especiall y any mention of hard di sk
space r equired, listed in thi s Technical Supplement.
2. If you still have a pl'Oblem, you should make copies of the ol'iginal di sks and use
the duplica tes in place of the ot'iginals; sometimes you'U get a t'ead en-Ot' due to a
diffet'ence in head alignment.
3. If the game still does n' t work, make sure you are not l'lmning a compression
utilit y program on your hat"d disk .
4. Finally, tt"y installing the game on another machine to see if the problem recut's.
Q. How do I copy disks?
Fl'Om the C: \> pl'Ompt, use the DOS command DISKCOPY A: A: [Retum]. Follow
the on-sct"een pt'ompts.
Q. Why won't my game load?
You must have 612,096 b ytes (598K) of Conventional Memor'y and 10K UMB (Uppel"
Memor'y Block) or' 620,288 bytes (606K) Conventional Memo.y and no UMB.
To check that you have allocated an uppe r' memot"y block, look fOI" the line
DOS=UMB (MS-DOS 6) ot" DOS=HIGH, UMB (MS-DOS 5) in you,' PC's
CONFIG.SYS fil e.
Slow Running
If yo u al"e not I' unning ft'om a boot di s k , please e n s ut" e that yo u have
SMARTDRV.SYS or SMARTDRV.EXE loaded into yo ut" CONFIG.SYS or
AUTOEXEC.BAT.
TECII\IC\L
Conventional Memory
To check how much Conventional Memory is available, type MEM/C from the C: b
prompt and press the Return key. Look for the Largest Executable Program
details . If there is not enough Conventional Memory, you may need a Boot Disk.
Q. What is a Boot Disk?
This is a Start Up disk for your computer which contains alternative start up files to
those on your hard disk. The Boot Disk will allow you more Conventional Memory.
Making a Boot Disk
Instructions for making an MS-DOS Boot Disk (also known as a System Disk) will
be found in your Microsoft manual.
U sing a Boot Disk
Inse rt the Boot Di sk into yOUt' flopp y di sk drive A and the n switch on the
computer. You should leave the disk in the floppy drive during play.
Q. Can I run my game through Windows?
No, this is not r ecommended , unless specifically mentioned in the system r equirements.
Q. Does my game run with DR DOS?
Success is not guaranteed. MicroProse games are currentl y designed to run with
MS-DOS 5.0 or 100% compatible DOS.
TEC''''C\L ~ I PPLE"E''''
Q. What is Base Memory?
Thi s i s the original 1Mb ( 1024K) III yo ur ma chine . It is divide d up into
Conventional Memory (640K) , wher e MS-DOS and all P C programs load and
Upper Memory (384K), wher e system driver s (such as the mouse driver ) r eside.
In MS-DOS 5.0 the bulk of the operating syst em and associated driver s are
normall y loade d into Uppe r Me mor y. Othe r dri ve r s h eld in the area of
Conventional Memory will r educe your 640K available for the program.
Q. What is Extended Memory (XMS)?
Further memory, beyond the 1Mb of Base Memory on your PC is called Extended
Memory. XMS can be used to free more Conventional Memory so that bigger games
can be run. XMS can also be used to simulate Expanded Memory.
Q. What is Expanded Memory (EMS)?
EMS was originally designed to give the PC more memory to run programs. It has
been around far longer than XMS so most programs take advantage of it. Most
MicroProse games take advantage of EMS. The DOS command EMM386. EXE can
be used to turn XMS into EMS and should be in your CONFIG.SYS.
Remember that hard disk space is also measured in Megabytes (Mb). Don' t confuse
this with memory - the two are completely differ ent!

sub-ca rr-ier ). The mission will end when
yo u pass through Waypoint 4. On ce
again you will be Debriefed (Look at the
money you' ve been allocated! ).
Tt'aining Missions continue in a similar
style, but in the next mission you will
be put under press ure. Get in, shoot a
robot sub and get out quickly!
Sonar
Whe n you b egin mi ssion s against
anything that i s going to shoot back ,
you 'n have to get to grips with Sonar
(Lower right on the Cockpit). Full details
are to be found in the Under Curt'ents
Magazine that came in your Sub War 2050
package (see page 6 Attack Tactics).
Basically, the quieter you are the less
chance ther e is of you being detected by
the enemy. Key S cycles through Sonar
Modes - Off - Passive - Active.
If you turn it Off you will not be able to
detect targets.
If you set it for Passive, you won' t give
away your position to the enemy during
high risk encountet s.
IT you set it for Active you' ll get the best
r es ult s but you'll b e in dange r of
detection.
The yellow bar scal e indicates how
' noisy' you are. It will change color to
r ed if you are being extremely noisy.
Extreme noise means early death!

INTRODUCTION
S
ubWar 2050 i s a unique simulation . It combines ele ments of s ubmarine
warfare, fli ght simulation and s trat egy game; se t in a r eali s ti c futur e
world scenario.
You take the part of one of the new breed of submarine r s, piloting the la t est in

THE MISSION
Piloting Your Submarine
You begin most missions under the submarine carrier, moments after launching.
Primary Controls
Submarine controls are split into three different groups -
Directional Controls which allow you to turn, dive and climb.
Engine Controls which allow you to control your speed.
Ballast Tank Controls which provide additional control over depth. These controls
may also be used when you are stationary, hiding from passive sonat".

with no change in its roll angle. Single-plane maneuvering is useful when you are
lining up on targets and when you are running on the surface.

The Head-Up Display
The Head-Up Display is overlaid on the 3-D di splay and shows the following data: -
Artificial Horizon
When your sub is not at a high nose-up or nose-down angle , you will be able to see
the at"tificial hodzon bar. This is displayed on the HUD as a short (Oe d line,
allowing you to see if your sub is in a level attitude.
Waypoints
When you reach a waypoint , it will be displayed on your HUD as a gr een tria ngle.
If you fl y through the centre of this triangle, your sub's na vigation sys tem will
automatically switch to track the next mission waypoint.
Thermal Layers
Thermal layer s are boundaries between warm and cool water which are set up by
ocean currents. They are very important to sub pilots because they reflect sonar
just like a mirror r efl ec t s light. If you position your sub with a thermal layer
between it and the enemy, you will be invisible to their sonar.
Thermal layer boundaries may be one of two t ypes :-
From warm to cool water - displayed on your HUD as a gr een grid.
From cool to warm water - displayed on your HUD as a red grid.
The rmal layer s are also useful to ori entate yo urself. For exa mpl e, if you are

including the time the object has been tracked for and the amount
of noise it i s making. Confidence fa ctors in excess of 100 are
required to guarantee a hit.
Note: if a torpedo is fired at you, it will be targeted automatically to give you the

Active Sonar sends out a
high-pitched 'ping' noise
and listens to the echo.
The data from
this sound profile is
projected onto the inside
I 'sil/g , t('lil' (' SOl/ar
of the submarine's
cockpit, enclosing the
pilot within a 3-D image
of the surrounding
underwater world.
If you are in a high-
threat environment, you
. should avoid using active
sonar; it broadcasts your
presence to the enemy
and may be used to
pinpoint your sub.

Passive sonar is simply an underwater microphone, listening out for the sound
of impellers or even the sound of turbulent water around the hull of a moving
submarine.
Passive sonar is less
effective than active
sonar, but does not
give away your
position to the enemy.
My personal pref-
erence is to stick with
passive sonar 90% of
the time, only 'going
active' when I am sure
that I am safe from
attack .

To set up an ambush, use
underwater rock or ice
to hide from

If your opponent detects
you, a close-range
maneuvering battle could
take place. I have always
tried to avoid these, since
they are usually very
hard work and any slight
mistake will leave you
dead. One of my
colleagues described sub
vs . sub dogfights as being
like a 'knife fight in a
telephone booth'.
lIidd('1I EII(,IIIi(' . .;
Enemies who are hiding
from passive sonar by
lying 'dead in the water'
may be scared into
moving by firing a
homing torpedo ' blindly'
in their general
direction. Avoid 'going
active' yourself; this will
almost certainly result in
the enemy launching a
torpedo at you.
If you get into a
maneuvering battle, try
to get into your
opponent's'six-o-clock'
(immediately behind)
and match speed and
maneuvers exactly.
Don' t forget to keep
your wits about you;
another suh could easily
move into your 'six'
while you are pursuing
your target.

Defensive Tactics
Defensive tactics are last resort measures which are carried out to
prevent your sub from being destroyed.
netllruillg Fin'
Firing a homing torpedo
down the bearing of a
running enemy torpedo
will often find a target.
Even if it does not, it will
delay the enemy sub's
follow-up attack while they
attempt to outmaneuver
your torpedo.

If you are piloting a deep
sea sub, dive out of the
enemy's range; you ca n
turn around and shoot
him from below. If you
are piloting a really fast
fighter, turn around and
speed off in the opposite
direction to the enemy.
Every sub has unique
features which you could
use to your advantage; it' s
up to you to exploit them.
Turning very tight in
the water generates a
pocket of turbulence
which can confuse
the active sonar of
homing torpedoes.
This pocket of
turbulent water is
known among fighter
sub cr ews as a

Avoiding Detection
Avoiding detection is more important than any other
consideration. If the enemy sees you before you see them, the
chances are that you will lose the fight.
Thermal layers are the
boundaries which are
set up by ocean
currents between the
sunlight-heated surface
water and the cooler
deep water.
When sonar first came
into use, submarine
cr ews discovered that if
they dived deep enough ,
ship-based sonar
suddenl y r eached a point
where it could not det ect
them at all. The
submarine had
disappear ed from sonar
beneath a thetmal layer.
Because sound travels
slower in dense cold
water , the sonar signal
was being r eflect ed back
up to the lowet' density
warm wat er , Submarines
have been using the ocean's
thermal layer s to hide
from sonar ever since ,
Thermal layer s are
displayed on your fighter
sub's 3-D cockpit display
as a grid of either r ed or
gr een. A r ed grid denotes
a thet'mallayer from
lower to higher
temperature water , a
gr een grid is a thermal
layer from higher to
lower temperature water.
If you position your sub
so that ther e is a thermal
layer between you and
the enemy, neither sub
will be able to see each
other. This is an excellent
defensive tactic,
In general , it is bes t to

they get the ch ance t o

This must only be carried
out if the enemy is
uncertain of your exact
position. Remaining
motionless reduces your
passive sonar emissions
to zero, forcing the
enemy to 'go active' and
give away their position
to you . This allows you to
lock and launch a
torpedo at them.
Cavitation noise is the
sound made by air
bubbles forming as a
result of water boiling at
the tips of a sub's
propeller/impeller blades.
It can r eveal your
submarine's position to
the enemy even if they are
using only passive sonar.

modern fighter subs are

The Pioneers
The first underwater vessels were open-
ended barrels lowered from ships by a
rope, these became known as 'diving bells '.
T
he principle of the
diving bell is simple:
an empty cup forced into a
bowl of water upside down
will not fill , air is trapped
inside the cup. The diving
bell was basically a huge
cupful of air which could
be breathed for a limited
period of time by an
underwater explorer. As
eady as 320 BC,
Alexander the Great
descended into the sea in a
diving bell to observe
underwater life. The
diving bell is not a true
submarine, however ,
because it can only travel
up and down, like an
elevator.
The first submarine was
an tmderwater boat built
in 1620 for the English
King James I by
Dutchman Cornelius van
Drebbel. The submarine
was made from grease-
oaked leather stretched
onto a wooden frame.
Twelve oars protruded
through watertight holes
in the leather , and twelve
oarsmen sat inside to
pl'Ovide propulsive power.
But no matter how hard
the oarsmen rowed,
Drebbel's submarine
could not dive and only
managed to plunge down
to about fifteen feet.
One and a half centuries
later , David Bushness in
the USA designed a
submarine for attacking
British ships. This tiny
craft, named Turtle, had
two man-powered
propellers, one for going
forwards or backwards
and one for ascending or
descending. On
September 6th 1776,
Turtle came very close to
sinking the British man-
of-war Eagle, but failed to
attach an explosive device
due to the tough, metal-
sheathed hull of the Eagle.
The Turtle continued
trying to sink British
ships, but was eventually
destroyed.
Another American,
Robert Fulton, designed a
submarine in 1800 for
Napoleon. This vessel was
the first submarine to
carry the name Nautilus.
It had many of the
features found on
modern submarines
including water ballast
tanks (used to dive and
surface) and a conning
tower (for the captain
to navigate the sub when
on the surface). It
generated considerahle
interest among the French
military, especially when
Fulton sank an old French
schooner as a demon-
stration. Napoleon's
admirals were not
impressed however ; they
felt that the submarine
was an ungentlemanly
weapon and persuaded
Napoleon to stick to using
surface warships. One of
Napoleon's officer's wrote
' This type of warfare
carries with it an
objection: those who
tmdertake it, and also
(\I)EI(\\ \TEI( \\ \I(F\I(E _
those against whom it is
launched , will all perish.
And this cannot be called
a gallant death. '
Fulton approached the
British and American
govelnments, but interest
was limited due to the
per ception of the
submarine as an
' underhand' weapon. He
went on to design the first
commercially successful
paddle steamer, but never
forgot his submarines. He
spent all of his paddle
stearnel pl"Ofits on building
an 80 foot armored
submarine called Mute,
but died before she could
be launched.
During the American Civil
War , the Confederate
forces built an
experimental submarine;
the CSS Hunley. This
little man-powered sub
was capable of true
underwater travel , but
drowned several cr ews in
training including Captain
H.L. Hunley himself.
Finally, the Confederate
forces decided to take the
Hunley into action and on
February 17th 1864, the
brand new Federal steam
sloop USS Housatonic
was attacked. The weapon
used by the Hunley was a
nose spar filled with 90
pounds of explosives. This
was jabbed into the side of
the Housatonic, a huge
explosion followed and the
enemy ship immediately
started sinking.
Unfortunately the Hunley
and her crew were
dragged down with the
sinking Housatonic.
In 1888, the first
submersible torpedo boat,
Gymnote was launched in
France. This vessel was
powered by a combination
of a petrol engine when on
the surface and batteries
when underwater. The
French soon found that
the petrol engine was not
ideal for submarine
operations because it gave
off poisonous vapors and
was inefficient in
operation. In contrast, the
batteries were ideal for
submarine use; allowing
the submarine to run
underwater for extended
periods of time. As well as
an advanced propulsion
system, Gymnote was
armed with the latest in
sub weapon technology;
the torpedo. Designed by
Robert Whitehead in
1868, the torpedo carried
an explosive warhead on a
steady course at a
predetermined depth,
making it deadly when
used against surface ships.
In 1904, the French
launched the Aigrette
which was the first sub to
be powered by a
r evolutionary new engine
designed in Germany by
Rudolf Diesel. The Diesel
engine burned oil without
a spark, which meant
that it did not give off the
poisonous vapors of the
petrol engine and was far
more effi cient. However
the early Diesel engines
wer e unreliable, and the
French continued to use
the steam engine in most
of their early submarines.
As the Diesel engine was
improved it did gradually
appear in service and
was eventually used to
power German sub-
marines in 1912.

World War I
At the outbreak of World War I , the
submarine was still very much in its infancy.
T
he types of submarine
operated by differ ent
countries varied widely
and more than half of all
the submarines in the
world were still the
inefficient, dangerous
petrol-engined variety.
Without a doubt , the
most formidable

I wer e the German
Unterseeboote (undersea
boats), known to the
Allies as 'U -boa ts ' . It
should be noted that
submarines are known to
sailors as ' boats' and
never as 'ships'.
The first success for the
U-boat came with the
sinking of a British
cruiser on September 5,
1914. Shortly after this,
on September 22, a single
U-boat sank three
armored cruiser s in less
than a quarter of an
hour. These events

submarine was truly a
force to be r eckoned
with. From now on , all
cruiser s were forced to
operate with a destroyer
escort to detect and deter
U-boats. Allied ships
were soon fitted with
' bulges' : light casings
filled with air and water
compartments to absorb
the impact of torpedoes.
U-boats started to make
their presence felt by
targeting Britain's food
supply. The British
fishing fleet was attacked
in the North Sea, but it
was in the Atlantic that
the U-boats did most
damage. The convoys
carrying supplies from
America to Britain soon
started to suffer heavy
losses . One of the most
tragic events of World
War I was the sinking of
the British passenger
liner Lusitania by a
U-boat , resulting in the
loss of 1, 198 passengers
and crew.
British submarines did
not have as many targets
as the U-boats, but still
managed to inflict heavy

losses. Patrols in the
North Sea sank German
fishing vessels and V-boats
wer e tracked down by
British hunter-killer
subs. During one raid in
the Mediterranean, the
t en year old British
submarine B-ll
penetrated five rows of
mines and sank the
Turkish battleship
Messoudieh .
In 1916, Allied destroyers
wer e fitted with the
' hydrophone', a device
for finding the position of
a V-boat from the noise
made by its propellers.
This device is still in use
today, as ' passive sonar' .
At the same time as
receiving the hydrophone,
Allied destroyer s wer e
issued with the first
depth charges . A depth
charge is basically a
drum of explosive fitted
with a h ydrostatic valve
to detonate it at a pre-
set depth.

Post-World War I
By the end of World War I, the submarine
had acquired a bad reputation among the
general public.
T
he sinking of
mer chant shipping
was seen as morally wrong
and popular sentiment
was for banning
submarines altogether.
In 1922, America ,
Britain and Japan
signed the London Naval
Treaty agreeing not to
perform unrestricted
submarine warfare on
mer chant ships. In the
meantime , Germany was
being forced to limit its
armed forces to
t'elatively low levels.
German submarine
research continued ,
however.
In 1935, the US
launched the first of an
advanced new type of
submarine, the ' P' class.
This boat had a
lightweight diesel engine
and a high-performance
batter y. This made the

In 1937, Germany
launched a very
powerful submarine; the
type VII U-boat. The
type VII had a
submerged displacement
of 871 tons, a maximum
speed of 17 kts surfaced
and 8 kts submer ged
and was armed with
l \I)EH\\ \TEH \\ \HF\HE
14 torpedoes. The cr ew
of 44 could stay at sea
for 20 days , allowing the
type VII to operate deep
into the Atlantic from
bases in France.
Sonar was deemed useful
enough to be fitted to
destroyer s, but early
models suffered by
being short-ranged and
easily confused .
One of the main
advances in post-World
War I naval technology
was SONAR (SOund
Navigation And
Ranging). This was a
device which used sound
to find the position of
submarines, tt'ansmitting
a loud 'ping' and
listening for the echo.

World War II
By 1939, submarines were starting to evolve
into very sophisticated fighting machines.
M
st World War II
ubmarines had a
diesel engine for use on
the surface, with an
electric motor for use
while submerged.
The batteries which
powered the electric motor
wer e charged from the
diesel engine while the sub
was on the surface. The
batteries allowed the sub
to travel for about an hour
when submerged at
maximum speed. Because
of the inefficiency of
early batteries, all
World War II subs had
a higher maximum speed
when surfaced than
when submerged.
The maximum diving
depth of most
World War II subs was
around 400 feet. In most
conditions this would
allow the submarine to
dive below the cold water
layer. Cold water , being
denser , reflected the
probing sonar waves of
enemy sub hunter s.
Early in the war, torpedoes
were powered by a steam
turbine. Unfortunately, the
fuel burnt to produce this
steam left a trail of
bubbles in the wake of the
torpedo, ' pointing' back to
the firing submarine. Later
in the war, electric
torpedoes like the American
Mk18 of 1944 put an end
to this problem.

The War in
the Atlantic
At the beginning of World War II the
Germans had 56 submarines to Britain ~
57. But while the German V-boats had
thousands of freighters as targets, the
British submarines could not attack
German food supplies which arrived
by rail, not sea.

soon littered with the
wreckage of Allied

Allies started desperately
searching for ways to
counter the ever present
German threat. Destroyer
escorts offered some
protection to the cruisers,
but the first year of the
Atlantic war belonged to
the U-boat. Sonar was
used on Allied destroyers,
but was not very effective
due to its limited range.

Throughout the war,

used extensively by the
British, Italians and
Germans. "Midgets" were
used to raid coastal
shipping, and a notable
success was the damaging
of the buge Gel'man
battleship Tirpitz at ABen
Fjord in Norway by the
British midget subs. A
typical midget sub was the
15 ton Gemlan Seehund
class with 2 torpedoes, 2
CI'ew, a maximwn speed of
6 kts and a range of just
500 miles. In January
1945, several of these
midget subs wer e operating
vel'y close to the British
shore, just off Margate and
in the Thames Estuary.
Meanwhile in the
Atlantic, the shipyards of
Britain, Canada and the
USA were producing ships
faster than the U-boats
could sink them. The
introduction of the
centimetric wave l'adal'
on Alli ed COI' vettes in
May 1941 gave the Allies
the ability to detect the
periscope of a U-boat
from a gr eat di stance.
Within a couple of years,
Allied anti-sub aircraft
were using radar to
detect U-boats and were
even Cal'fying out attacks
at night.
The U-boats tarted using
a new weapon in 1943; the
acoustic homing torpedo.

torpedo and it detonated
harmlessly, far away from
its intended target.
The Allies were still
having problems with
their sonar systems. They
were fmding that a slight
disturbance in the sea
would dl' amatically
reduce the effectiveness of
their sonar. This meant
that, due to the waves to
the side and r ear of a
destroyer, sonar was only
effective when the
destroyer was facing a
V-boat . The Allies
decided to put sonar onto
buoys, floating still in the
water, in 1944. This
device would radio the
position of submer ged
vessels back to Allied
destroyers or anti-sub
aircraft. Depth charges
could then be placed with
deadly accuracy. The
sonar buoy came to be
known as the 'sonobuoy'
and is still in use today.
In 1944, Allied radar
forced V- boats to start
using a device called a
Schnorkel. This allowed
them to run their diesel
engines while submerged
at periscope depth. The
Schnorkel was basically
a pipe, similar to the
'Snorkel ' used by divers,
but with the addition of
a valve to close off the
pipe when it went under
the water.
Towald the end of the
war, V-boats we I'e fitted
with the formidable
Schnee-Orgel10-tube
torpedo launcher , which
sent a heavy batter y of
torpedoes at the target.
This was highly effective
when it was used , but the
system did not come into
widespread use before the
end of the war .
The ultimate V-boat was
the type XXI, which
implemented all the
lessons learned from
early V-boats. The
improvements included a
streamlined hull ,
improved battery power
output, a Schnorkel and
a rapid-reloading system
for the torpedoes.
V2511 , the first type XXI
V-boat, was launched in
1945, one week before the
German surrender . It went
on to evade several sub
hunting vessels and made
an undetected dununy
attack on a British cruiser
before surrendering. The
history books wer e closed
for the V-boat, but the
type XXI heavily
influenced the design of all
future submarines.

The Pacific War
The Japanese attack on Pearl Harbor, Hawaii
on December 7, 1941 marned the oulbreak of
the war in the Pacific. The submarine was to be
one of the most important weapons of this war.
I
t was involved right at
the start when the
J apanese sent five midget
submarines to Pearl
Harbor , to attack any
survivors of the air raid.
Even though they
managed to penetrate
some harbor defenses, all
five midgets wer e
destroyed and no more
US ships wer e attacked.
The Japanese had more
than just midget subs,
however . The main
Japanese submarines wer e
known to the Allies as
' I-boats', and their design
was heavily influenced by
the German U-cruiser s of
World War I. The
Japanese even built a
submarine which
displaced 5000 tons and
could operate 3 seaplanes
from its deck. Heavily
armored, it was not a
practical vessel because it
was slow to dive and
clumsy to handle.
While Japanese
submarines did manage to
sink a number of US
carrier s they wer e not
used as effectively as the
German submarines in the
Atlantic. The Japanese
tended to use their subs
defensively, keeping them
close to surface vessels
and never fully exploiting
their offensive potential.
The Americans wer e
learning from the Atlantic
war, and US Navy
submarines in the Pacific
borrowed German tactics.
US subs experimented
with ' wolf packs' and
eventually settled on using
three boat ' wolf packs' . As
well as simply attacking
ships, American subs also
shadowed the main
Japanese battle fleets,
reporting their movements
to other US forces.
When US submarines
attacked a Japanese
convoy, they would target
the larger cargo vessels
first and dive to escape the
inevitable depth charges
which followed . This was
the same tactic as that
used by the U-boats
during the first years of
the Atlantic war. It was
ver y effective against the
J apanese supply lines.
In 1941 the first Gato class
submarine was launched .
The Gato class was the

subs built during World
War II. This meant that

with the prototype
EMDI d'l"ive. This sub
promptly set up a new
world submarine speed
r ecord of 59 kts on
May 31st 2008, during
the first EMDI sea trial.
The first production
EMDI sub, the 19, 800
ton Nevada class of
2007 was also the first
EMDI sub to be fitted
with a variable pitch
fan. By stopping the fan
and rotating its blades
to align with the flow
through the impeller,
the Nevada could run in
total silence at speeds
up to 21 kts. Unde r full
EMDI power, Nevada
could run safely at up
to 57 kts.
The First Advanced
Technology Submarines
~ s silent drive subs
J-i.hecame more wide-
spread, pioneering
engineers at Legendre
Sous-Marins (LSM) in
France began work on
a new concept in
submarines. They
realised that, as well as
being stealthy, a
submarine needs to be
fast and maneuverable.
They established that the
main cause of drag on a
submarine was turbulence
close to the surface of
the hull . To get rid of this,
the new sub would be
coated with a very rough
skin, the texture of which
was inspired by the skin
of sharks.
With very large dive
planes for increased
maneuverability, power
from a lightweight fusion
r eactor linked to a
standard EMDI drive and
all-composite structure,
the new sub promised
unrivalled performance.
Construction began on a
prototype to test these
new theories. To further
emphasise the advanced
design of this sub, LSM
named it Nautilus.
The Nautilus was
launched at Chel"bourg
on January 21 , 2014,
exactly 60 years after the
USA launched their
nuclear Nautilus. The
new sub was as much of a
revelation as its 1954
nuclear namesake and
went on to raise the
tmderwatel' speed record
to 63 kts. More
importantly, its advanced
design allowed it to
outmaneuver any torpedo
then in existence.
The design of the Nautilus
was used as the basis for
the Requin Tigre class of
2017 which was produced
in very large numbers
and sold by LSM to,
among other s, Russia
and America.

TECHNICAL SUPPLEMENT
FOR MICRO PROSE CD ROM TITLES
TECHNICAL REQUIREMENTS
All MicroProse CD ROM titles require the following: DOS 5.0 or higher, a hard drive, a CD ROM
drive, the Microsoft CD ROM Extension (MSCDEX) version 2.1 or higher, 2 MB of Expanded RAM,
and a VGA Graphics Card. Each product will call for different hardware configurations. Reference
the box label for specific hardware details. Enhanced CD ROM titles such as F-14 Fleet Defender
and BloodNet may require a Sound Blaster compatible sound card for certain game features.
INSTALLATION
The installation of MicroProse CD products is very simple. Just follow the instructions below, and
you'll soon be playing one of the coolest games known to mankind.
Turn on your computer, making sure that the Microsoft CD ROM Extension is loaded.
Place the CD in the CD ROM drive.
Make that drive the current drive. (Type the letter of that drive [usually OJ, followed by a colon,
then press [Enter].)
Type the word INSTALL and press [Enter].
Follow the on-screen instructions.
Several MicroProse titles will copy files to your hard drive. These are only the files that are
absolutely necessary to play the game and take up a minimum amount of hard disk space. Some
MicroProse CD titles, such as World Circuit, will allow you to decide how many files you want the
installation program to copy to your hard drive.
Many MicroProse CD ROM products will temporarily use expanded memory and hard disk space
to cache information. This "caching" process will take a few moments but will allow scenes to play
much faster and will enhance your gaming experience.
RUNNING THE GAMES
After the installation is complete, the install program will instruct you how to start each game or
game pack. Simply repeat those instructions each time you wish to replay the game.
