The M1 Abrams eclipsed for the last thirty years all past MBTs to date, including the M48/M60 series. It represented a definitive change in US tank design since World War 2 and was engineered with the crew protection in mind, but without sacrificing either the firepower or mobility. Since numerous reports from the 1973 Yom Kippur war were carefully...
The MBT 70 (For “Main Battle Tank, 1970) was an attempt to devise a joint US-German project for a new battle tank. US Army already evaluated the Leopard when in Germany in the 1960s and it was clear that both countries learned a great deal about the evolution of tactical warfare and ideas revolving on new concepts based on armored mobility, with ne...
Soon, the original MBT 70 program estimated $80 million (292.8 million DM) plan was shattered, as in 1969 the project cost was $303 million (1.1 billion DM). The Bundestag stopped all further developments and the Bundeswehr used what was already gained to built the Keiler (Future Leopard II). The US. Congress eventually canceled the MBT-70 in Novem...
Hull
The hull is made of solid RHA, a single block made of massive parts welded together (bottom, front beak, glacis plate, sides, rear plate), with compartmentation. The driver is located in the front center, at the feet of the turret ring, with three periscopes (see later) and a one-piece hatch which can be opened at any time in regards to the turret. The particular hull front is composed of a beak sloped downwards, which joined an almost vertical glacis plate up to the turret. The hull armor is...
Propulsion
The big heart of the Abrams, siege of unparalleled performances, is the Lycoming AGT 1500 multi-fuel gas turbine (later manufactured by Honeywell) capable of delivering 1,500 shaft horsepower (1,100 kW). It was served by a six-speed (four forward, two reverse) Allison X-1100-3B Hydro-Kinetic automatic transmission. Top speed was 45 mph (72 km/h) on paved roads, and 30 mph (48 km/h) cross-country with a governor, but up to 60 mph (97 km/h) on road with the engine governor removed, which was wa...
Turret
For the first time, the Turret was designed from the beginning to operate a laser range finder, a ballistic computer, a gunner thermal-imaging day and night sight, a muzzle reference sensor to measure the gun-tube distortion and a wind sensor. It was a real leap forward compared to previous generations. The crew of three take place inside the central inner turret, with a standard loader instead of an autoloader. The latter was a uniquely shaped pentagram, with a sloped faceted nose, flat side...
The major upgrade of the Abrams, centered around a new 120 mm smoothbore gun and a series of protection improvements and other upgrades, designed to keep pace with contemporary advanced Soviet designs such as the T-64A, upgraded T-72, and the T-80. External differences are easy to spot: The turret is the “long” model, at the rear with a rear bustle...
The M1A2 is the sum of improvements over the M1A1, but moreover and brand new FCS with a powerful computerized core, and consisted in a commander’s independent thermal viewer and weapon station, a new position navigation equipment, and other controls and displays managed by a central digital data bus. More data can be treated simultaneously, improv...
This latest version is under development, prototypes were delivered in 2014, and operational production was estimated to be by 2017, when the Army first planned to re-launch the Lima tank plant production. The sum of improvements includes a lighter L44 120 mm gun, new road wheels with improved suspension and a more durable track, a lighter armor an...

The original builder, Chrysler Defense, ceased to built the Abrams in 1995, which was to be followed by the Lima Army Tank Plant in 2013 as planned by the Army. However General Dynamics Land Sys...
The Abrams Integrated Management (AIM) program overhauls old M1A1s to original factory standards, a program first initiated in 1997. First step is performed at the Anniston Army Depot in Alabama, since 1998. Hulls are separated from the turrets, components are uninstalled, treated and stored separately. Both hulls and turrets are sandblasted until ...
There are still some questions about the Abrams relevance as a potential 4th generation MBT in the next twenty years. A tank is not a nuclear aircraft carrier, and although the upgrade process could be done indefinitely, there are regular concerns about future weapons systems in adequacy to new (mostly asymetric) threats, and cheaper vehicles to op...
