M1A2D [ex M1A2 SEPv4]

The M1A2D [ex M1A2 SEPv4] upgraded Abrams must be fielded in the 2020s before an entirely new vehicle can be deployed. Army This perhaps-last Abrams variant is equipped with more lethal Advanced Multi-Purpose ammunition (AMP), integrating many rounds into one 120mm round, and third-generation Forward Looking Infrared Sensors (FLIR) designed for better resolution and increased range.

Testing for the SEP v4 variant will commence in 2021, and will include color cameras, new slip-rings, new laser-rangefinder technology, integrated onboard networks, laser-warning receivers, advanced meteorological sensors and ammunition data links.

In November 2016, Maj. Gen. David Bassett, program executive officer for Ground Combat Systems, described FLIR as "A combination of mid-wave and long-wave sensors [that] allow for better target identification at long ranges and better resolution at shorter ranges." He also said the upgrade will adapt to different environments better than previous variants. "You do not have to manually put meteorological variables into the fire control system. It will detect the density of the air, relative humidity and wind speed and integrate it directly into the platform," he said

In late 2017, the Abrams Modernization Team received the Abrams SEPv4 ECP contract, which will upgrade the M1A2 SEPv3 to M1A2 SEPv4 Abrams tank. The SEPv4 will be designed to be more lethal, faster, lighter, better protected and equipped with new sensors. The lethality effort will include development and integration of new laser rangefinder technology, a color day camera, integrated on-board networks, new slip-rings, advanced meteorological sensors, ammunition data links, laser warning receivers and other enhancements to ensure the warfighter will continue to have the most advanced, lethal and combat proven main battle tank in the world.

Engineering Change Proposals - ECPs - can extend a programs life cycle, increase its lethality and maintain its battlefield superiority through upgrading, replacing and recapitalizing efforts. The biggest differences of working on modernization of current vehicles vice the development and support of new programs is being constrained to the parameters of the current vehicle design and systems. With ECPs not every technology in the vehicle is being replaced, so there are size, weight, power, cooling and cost, or SWAP-CC, considerations with the insertion of new technologies. Additionally, if part of the ECP effort is introducing a whole new technology you have to ensure that there is a space claim for it, as well as the power generation requirements to power the new system.

ECPs allow the Army to upgrade ground combat vehicles at key and strategic points throughout the tanks life cycle. It has continually upgraded the Abrams with reduced risk and cost, while taking advantage of the current technologies that each ECP offered to increased mobility, protection and lethality.
