M1A2 Abrams tank (MBT)

M1A2 Abrams tank (MBT)

The ABRAMS tank (M1A2) is currently in operational usage by the United States of America and is the US’ main battle tank. Usage of this tank consists of four crewman being driver, commander, loader and gunner. It’s currently being used by the United States, Kuwait, Saudi Arabia and Egypt. (Perhaps more) Notably this version of the M1-tank series has been used in Iraq. The unique feature about this tank is that it is powered by turbine engine. (Honeywell AGT 1500) However upgrades were on the way for a new turbine engine which is to be smaller, which gives much more acceleration as well as outputting no visible exhaust; this new engine is called the LV100-5 gas turbine created in combination by General Dynamics and Honeywell International Engines.

Armaments

The main gun armaments on the M1A2 is the M256A1 120 mm smooth bore which is a German design by Rheinmetall AG.

There is also another gun mounted on the roof, this is the M240 machine gun which fires 7.62 mm bullets, this has a defense shield mounted around the gunner to protect him when in combat. The same machine gun is also used with the coaxial gun to the right of the main gun however to compensate for the different position of the coxial, the same fire control system is used, which also compensates for any bullet drop so the gun fires straight onto the target as like the main tank of the gun. (For both main & coxial gun)

Types

M1A2 TUSK (Tank Urban Survival Kit) is kit that features upgrades updated onto current M1A2 vehicles either out in field or at base. The kit upgrade includes a remotely operated 50. calibre machine gun (CROW) as well as a defence shield mounted on top of M240 machine gun. Along with this kit includes explosive reactive armour (ERA) upgrades on the sides of the tank which helps protect the vehicle further against anti-tank missiles, explosives and shrapnel. The kit came into place so the tank could survive much at a higher ratio in urban environments. Being the that the explosive reactive armour protects its sides and can also be placed on the rear of the tank where in urban environments fire can take place from all directions where the tanks main gun cannot get enough elevation on a target to shoot it. – Thus the remotely operated 50. calibre comes into play where it can fire at high angles as well as act as a second defence mechanism in an urban environment where it can fire off rapid amounts of fire in different or same directions as the main gun accurately as well as the crewman being at safety inside the tank.

M1A2 system enhancement package (SEP) - The system enhancement package was a package developed to enhance the fighting mobility of the M1A2 which the US military first conducted and signed contracts with ‘General Dynamics Land Systems’ in 2001. They were first contracted to supply 240 enhanced M1A2′s by 2004. The enhancements included improved thermal imaging systems (Raytheon’s commander independent thermal viewer), improved digital display for digital colour terrain maps for the commander of the vehicle and a drivers integrated display along with thermal imaging management system. There have been further orders from the US Army, in June of 2005 60 M1A2 tanks were ordered in the system enhancement package configuration and in 2006 another huge order of 250 M1A2s were also ordered in the SEP configuration. Then in 2008 GE was awarded to upgrade 670 M1A2 to the SEP v2 configuration. The version 2 of the system enhancement package (SEP) included a tank-infantry phone, improved sights and displays.

    Great inf on the M1A2. Are you going to also do information on the M1A1?

    Seeing as the M1A1 is really an M1A2 however with a lot of upgrades and not really to many design changes. For example, the Challenger 1 in comparison to design change… well there is a lot of design change in that.

    cheers

    Like on the leclerc this is a good article but the picture shown here is the m1a1 not the m1a2. key difference is that the m1a2 has a periscope on the left hand side of the turret for the commander giving it a hunter killer capability. cheers bye
