US M1A2SEP main battle tank: probably the world’s most capable tank

The M1A2SEP is a successor to the M1A2. It is also an upgrade package for the older Abrams tanks. It has improved armor protection, improved system components, improved computer components, and some other improvements.

The M1A2SEP main battle tank is the latest and most advanced model of the “Abrams” main battle tank. It is equipped with a second-generation thermal imaging system, an independent thermal imager for the commander, a true-color flat-panel display, a digital terrain map, Thermal control system, and the latest digital command, control, and communication equipment. The M1A2SEP main battle tank is known as the “robot in the main battle tank,” It is also the most advanced tank model in the Abrams main battle tank series. It uses the latest thermal imaging system, digital topographic map, accurate color flat-panel display, digital command, control, and other advanced information equipment. It is also the proudest design of the Abrams tank.

The baseline M1A2 tank uses advanced armor, reinforced with depleted uranium layers. The M1A2 SEP has a further upgraded depleted uranium armor components with graphite coating. Protection of this MBT is considered as one of the best in the world. The M1A2 SEP has significant level of protection against all known anti-tank weapons. It can also employ counter-IED equipment. Protection can be further increased with add-on explosive reactive armor.

The United States can say that in this regard, Under the blood. Its primary weapons are a M256 120mm smoothbore gun  Range of effective fire is in excess of 4 km. It can fire the M829A3 APFSDS rounds with depleted uranium penetrator and M1028 canister rounds that discharges massive blast of tungsten fragments at muzzle exit

The SEPv2 (version 2) added CROWS or CROWS 2 remotely operated weapon station, armed with a 12.7 mm machine gun. This weapon can be fired from inside of the tank without exposing the crew to enemy fire. Also there are two 7.62 mm machine guns. One of them is mounted coaxially with the main gun. The other is mounted on top of the roof and is operated by the loader.

At the same time, the infrared night vision device can magnify the target by 50 times to more accurately lock the target. Enhanced armor-piercing shells and various other shells can be used in ammunition and close combat. Because it is equipped with advanced digital systems, this tank has exerted great power on the Iraqi battlefield.

The advanced M1A2SEP main battle tank is mainly advanced on SEP. SEP stands for system components, which involves many aspects such as sighting, fire control, weapons, power, communication, protection, and vehicle management. The second-generation forward-looking infrared night vision device is also a prominent technical highlight of the M1A2SEP tank. Its night vision is vastly improving over the M1A1 in the Gulf War. The maximum detection range of the M1A1 is 4 km, while the M 1A2SEP reaches 6.8 km.

When performing surveillance tasks, the M1A2SEP’s forward-looking infrared night vision device can be used with low magnification to ensure a wide field of view and a clear target image. When using a narrow field of view to identify friends and foes, the M1A2SEP can use 50x magnification to identify target features.

The M1A2SEP main battle tank has a width of 3.658 meters, and the bottom of the vehicle is 0.482 meters above the ground. Its maximum speed is 68 km/h; the off-road speed is 48 km/h.

The US State Department has recently approved a probable USD 6 billion Foreign Military Sale to Poland of M1A2 SEP main battle tanks (MBTs) and supporting equipment. Poland has requested 250 M1A2 SEPv3 Abrams MBTs from the government of the US.

Future Development 

The SEPv3 (version 3) (also known as M1A2C) was publicly revealed in 2015. Today it is the most modern version of the Abrams tank. It has a number of upgrades in the area of survivability, maintainability, fuel efficiency, and network capabilities. Main survivability upgrades are the new armor package, modified active protection system, upgraded fire control system, new munitions and improved anti-IED capability. The SEPv3 tanks can fire the new XM1147 Advanced Multi-Purpose programmable munitions as well as M829A4 Advanced Kinetic Energy munitions. It uses a modified Raphael Trophy HV active protection system. The tank is fitted with a new electronic device, which jams remotely controlled IEDs.
