Capsule:
The Sentinel is the main battle tank in service with the Heiter Industries
Armed Forces. It replaced the aging Devastator Mk2 tanks. The Sentinel
features increased firepower, improved mobility, fire control systems and
armour.
Designed with the "form follows function" premise in mind, and knowledge of
the many failed Main Battle Tank attempts of other companies, the Sentinel
is quite revolutionary. The most obvious of it's traits is it's very low
profile. The Sentinel is only 3.56 meters tall - when its hovering a meter
off the ground. When compared to the 4 and 5+ meter tall tanks, the 2.56
meters of the Sentinel make it a very small target. The short height make
the Sentinel a much harder target to hit, and it aids the tank when it is
in the hull-down position behind a sand berm or the crest of a hill. At
4.28 meters wide, the Sentinel is also much narrower than most
tanks. The Sentinel's relative narrowness help it to navigate the narrow
streets of most cities, since not all cities have 10 meter wide boulevards.
Development of the Sentinel Mk 2 has begun and will include a new
compressed gas recoil system and improved thermal sleeve for the main gun,
to enable the firing of enhanced kinetic energy ammunition, and improved armor.
ARMAMENT
The Sentinel's main gun is the 150 millimeter L35 smoothbore cannon
developed by the Ordnance division of Mechan Arms. The gun is made from
electro-slag refined durasteel (ESR) and is insulated with a thermal sleeve
made by Heiter Technologies. The sleeve increases accuracy by preventing
distortion through the effects of heat and shock. The L35 is also fitted
with a muzzle reference
system and fume extraction.
A Heavy Blaster Cannon is mounted on the turret to the right of the 150mm
cannon, providing the tank with a secondary weapon for targets too lightly
armored to warrant the use of the main gun. Only one of the weapons can be
fired at once, either the main gun or the blaster cannon. The two weapons
are aimed in parallel, about 70 centimeters apart: where one weapon aims,
so does the other. Like the L35, the heavy blaster cannon is fitted with a
muzzle reference system.
A light blaster cannon mounted on the turret below and between the two main
weapons provides the firepower to deal with unarmored and lightly armored
vehicles such as personnel carriers.
Two light repeating blasters mounted on the left and right side of the
turret gives the Sentinel the ability to deal with infantry. The operators
must exit the turret and expose themselves to fire and environmental
hazards in order to use them (getting half cover instead of full).
The turret is capable of 360 degree rotation and the weapon elevation range
is from -10 to +30 degrees for the main gun and -10 to +40 degrees for the
heavy blaster cannon.
HULL
The hull is in three sections: the driving compartment at the front, the
fighting section in the center, and the engine at the rear of the vehicle.
The Sentinel incorporates durasteel encased depleted duranium armor. Though
rated at only 1/12 the strength and resiliency of molecular armor, it is
still tough enough to shrug off anything short of a turbolaser. Armored
fire proof bulkheads separate the crew compartment from the fuel tanks and
ammunition. The tank is protected against nuclear, biological and chemical
(NBC) warfare.
The turret is located in the center of the vehicle. It is quite spacious
inside, with more than enough room for it's three occupants to move around.
There are three crew positions: the commander in the rear right, the gunner
in the front right, and the loader in the rear left. A small hatch in the
front left of the turret leads to the driver's compartment. The inside is
painted white and is covered with a thick spall liner. In the event of
weapon penetration through the armor, the spall liner reduces the number of
fragments and narrows the fragment cone. The spall liner also provides
noise and thermal insulation. The reinforcement provides protection against
multiple strike, kinetic energy rounds, shaped charges, and energy weapons
such as blasters, turbolasers and lasers.
At the rear of the vehicle is the engine compartment. The Mechan Motors
MTU-873 Fusion reactor provides power. It produces 20% more power than the
tank is capable of consuming at any time. Also in the engine area is the
60MT-rated repulsorlift generator, which sends it's power to the eight
repulsorlift emitters running down the left and right sides of the tank.
The 25 fuel cells that feed the power generator are also stored here. They
are quickly accessible through hatches and give the Sentinel a continuous
operating time of 36 hours, 24 hours for combat purposes.
CREW POSITIONS
The driver sits at the front of the vehicle, in a highly reclined position
(20 degrees above horizontal), reducing the height of the hull and aiding
the low profile of the tank. The driver's compartment is equipped with two
observation periscopes on either side and a central image intensifying
periscope for night vision. The periscopes provide a 120 degree field of
view. The Heiter Tech Driver's Vision Enhancer (DVE), AN/VSS-5, is based on
a 328 x 245 element uncooled infrared detector array, operating in the 7.5
to 13 micron waveband. It provides accurate nightvision out to one
kilometer. A camera with a 65 degree horizontal and vertical field of view
positioned at the rear of the vehicle and a television monitor provide a
reversing aid for the driver.
The commander's station is equipped with six periscopes, providing 360
degree view. The Commander's Thermal Viewer (CTV) provides the commander
with independent stabilised day and night vision with a 360 degree view,
automatic sector scanning, automatic target cueing of the gunner's sight
and back-up fire control.
The Sentinel has a two-axis Gunner's Primary Sight- Line of Sight (GPS-LOS)
which increases the first round hit probability by providing faster target
acquisition and improved gun pointing. The Thermal Imaging System (TIS) has
magnification x10 narrow field of view and x3 wide field of view. The
thermal image is displayed in the eyepiece of the gunner's sight together
with the range measurement from the laser rangefinder. The Heiter Tech
Laser Rangefinder (LRF) has a range of 10 kilometers, accuracy to within
one meter and target discrimination of two meters. The gunner also has an
auxiliary sight with magnification x8 and a field of view of 8 degrees.
FIRE CONTROL
The digital fire control computer is supplied by Heiter Technologies. The
fire control computer automatically calculates the fire control solution
based on: lead angle measurement; bend of the gun measured by the muzzle
reference system; velocity measurement from a wind sensor on the roof of
the turret; data from a pendulum static cant sensor located at the center
of the turret roof; outside temperature; barometric pressure; gravity;
ammunition temperature for the L35; and power and gas resources for the
heavy blaster cannon. The operator manually inputs data on ammunition type.
The gun control is provided by an all-electric gun control and
stabilisation system. It allows the tank to engage moving targets
accurately while on the move.
