US ARMY

3. INTRODUCTION
 The M1 Abrams is an American third-generation main battle
tank produced by the United States.
 It is named after General Creighton Abrams, former Army Chief of
Staff and Commander of U.S. military forces in the Vietnam War from
1968 to 1972.
 Highly mobile, designed for modern armored ground warfare, the M1
is well armed and heavily armored.
 Notable features include the use of a powerful gas turbine engine
(multi fuel), the adoption of sophisticated composite armor, and
separate ammunition storage in a blow-out compartment for crew
safety. Weighing nearly 68 short tons (almost 62 metric tons), it is one
of the heaviest main battle tanks in service.

5. ARMAMENT
 The main armament is the 120mm M256 smoothbore gun,
developed by Rheinmetall Waffe Munition GmbH of Germany.
 The 120mm gun fires the following ammunition - M865
TPCSDS-T and M831 TP-T training rounds, the M8300 HEAT-
MP-T and the M829 APFSDS-T which includes a depleted
uranium penetrator. Textron Systems provides the Cadillac Gage
gun turret drive stabilization system.
 The commander has a 12.7mm Browning M2 machine gun and
the loader has a 7.62mm M240 machine gun. A 7.62mm M240
machine gun is also mounted coaxially on the right hand side of
the main armament.

7. DEPLETED URANIUM ARMOUR
The M1A1 tank incorporates steel-encased depleted
uranium armour.
Armour bulkheads separate the crew compartment
from the fuel tanks.
The top panels of the tank are designed to blow
outwards in the event of penetration by a HEAT
projectile.
The tank is protected against nuclear, biological and
chemical (NBC) warfare.

9. PROPULSION
The M1 is equipped with a Honeywell AGT 1500 gas
turbine engine.
The Allison X-1100-3B transmission provides four
forward and two reverse gears.
The US Army has selected Honeywell International
Engines and Systems and General Electric to develop
a new LV100-5 gas turbine engine for the M1A2.
The new engine is lighter and smaller with rapid
acceleration, quieter running and no visible exhaust.
