M1A1 Abrams

The definitive Cold War-era Abrams standard, replacing the original 105 mm gun with a licensed 120 mm Rheinmetall smoothbore and adding NBC protection. Thousands remain in U.S. Marine Corps and allied service or storage, and it forms the base for many export upgrade programs.

Full specifications

Performance

Speed, range, altitude and engagement capability.

Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.: 67 km/h

Stronger than 48% of main battle tanks
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.: 465 km

Stronger than 45% of main battle tanks
Power-to-weight Engine power per tonne of vehicle weight. Higher means better acceleration and cross-country mobility.: 24.4 hp/t

Stronger than 72% of main battle tanks
Muzzle velocity Projectile speed leaving the barrel. Higher means flatter trajectory and better armor penetration.: 1,655 m/s

Stronger than 41% of main battle tanks

Firepower

Armament, payload and guidance.

Main armament Primary weapon: main gun, cannon or missile type.: 120 mm M256 smoothbore cannon
Secondary armament Additional weapons: coaxial MG, remote weapon station, gun pods.: .50 cal M2 + 2x 7.62 mm M240 machine guns
Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better — ammunition commonality matters.: 120 mm
Ammunition Rounds carried (main gun) or standard magazine capacity.: 40

Stronger than 42% of main battle tanks

Protection

Armor, countermeasures and survivability.

Armor Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.: Composite armor with depleted-uranium mesh inserts
Reactive armor Explosive reactive armor (ERA) blocks that disrupt shaped-charge jets.: No
Countermeasures Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.: smoke grenade launchers
NBC protection Sealed crew compartment with overpressure filtration for nuclear/biological/chemical environments.: Yes

Physical

Dimensions, weight and crew.

Length Overall length including gun/probe where applicable.: 9.83 m
Width Overall width — matters for rail/road transport of vehicles.: 3.66 m
Height Overall height. Lower profile is harder to spot and hit for ground vehicles.: 2.44 m
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.: 63,100 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.: 4

Propulsion

Engine, power and fuel.

Engine Powerplant model and type.: Honeywell AGT1500 gas turbine
Engine power Engine output power. Higher moves more weight faster.: 1,500 hp

Stronger than 85% of main battle tanks
Fuel capacity Internal fuel volume.: 1,900 L
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…: Gas turbine

Sensors & avionics

Radar, sensor suite and datalinks.

Sensors IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.: thermal imaging sight
Thermal imaging Thermal sights for night and obscured-visibility operations.: Yes

Program

Cost, production scale and operators.

Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.: 4,796

Top 7% of main battle tanks
Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 6

Stronger than 83% of main battle tanks
