- The Army has awarded a monster $4.62 billion contract to General Dynamics Land Systems to produce M1A2 SEPv3 tanks for the service over the next eight years.

- M1A2 SEPv3, known as M1A2C, is the latest version of the venerable Abrams tank, and it has been upgraded and is set to be "the foundational variant for all future incremental upgrades."

It's been more than three years since the Army first took delivery of the first of its souped-up new version of the M1 Abrams main battle tank, and the service clearly likes what it sees.

The Defense Department announced on Friday that the Army has awarded a monster $4.62 billion contract to defense giant General Dynamics Land Systems to produce M1A2 SEPv3 tanks for the service over the next eight years.

Also known as the M1A2C, the new Abrams variant "rectifies many of the space, weight and power issues identified during Operation Iraqi Freedom and will be the foundational variant for all future incremental upgrades," according to the Army.

Outfitted with fresh survivability enhancements and a new power system, the SEPv3 purportedly boasts improved main gun accuracy with "smart cannon" munitions programmable over data link and reinforced armor bolstered by a built-in jammer to counter radio-triggered improvised explosive devices.

As of February 2019, the SEPv3 upgrade also included the Israeli-developed Trophy HV hard-kill active protection systems that use radar to detect incoming missiles and rockets then fires tiny projectiles to intercept them.

23 JULY 2020

Soldiers at Fort Hood, Texas, have begun receiving the US Army’s M1A2C Abrams main battle tank (MBT), also known as the known as the M1A2 System Enhancement Package (SEP) version 3 (M1A2 SEP v3), and are preparing for upcoming live-fire exercises.

On 21 July, the service announced that over the past few weeks it has been delivering the vehicle upgrade to members of the 3rd Battalion, 8th Cavalry Regiment, 3rd Armored Brigade Combat Team, 1st Cavalry Division.

“This is the first time we have fielded a new tank in about 16 years,” said Lieutenant Colonel Nicholas Sinclair, commander of 3rd Battalion, 8th Cavalry Regiment. “We will be the first ones trained on this so it’s really special to us to make sure we’re doing it right.”

Soldiers will spend several weeks learning about the tank, and how to operate, maintain, and utilise it in preparation for fielding. To accelerate the process, each tank includes an embedded trainer to help soldiers repeat activities even when the vehicle is stationary, Lt Col Sinclair explained.

Extensive improvements have been implemented to the latest M1A2C and D (formerly designated M1A2 System Enhancement Package version 3 or SEPv3 and M1A2 SEPv4, respectively) versions such as improved composite armor, better optics, digital systems and ammunition. The Abrams was due to be replaced by the Future Combat Systems XM1202 but due its cancellation, the U.S. military has opted to continue maintaining and operating the M1 series for the foreseeable future by upgrading with improved optics, armor and firepower.


The M1A2 SEP V3 (System Enhanced Package) is a modernized version of the M1A2 SEPV V2 main battle tank which has a number of upgrades in the areas of survivability, maintainability, full efficiency and network capability. In October 2015, the M1A2 SP V3 was presented for the first time at AUSA, defense exhibition in Washington D.C.  Interview Tim Reese General Dynamics Land Systems about M1A2 Abrams SEP V3 at AUSA 2015.
