Two rectangular casings containing sensors for the AN/VVR-4 laser warning system are installed symmetrically on the front of the side. Multiple more gadgets are seen on the tower. It may be distinguished from earlier versions by its frontal armour, which has been upgraded and has a slightly different form. The turret is taken without modification from the M1A2 SEP v.3 tank. The prototype tank’s hull preserves its original look only the inside parts of the new project were modified. The MBT is upgraded to SEP v.3 levels and additional equipment for the futuristic tank project. Specifically, it may be inferred that it was rebuilt from a tank of one of the older modifications, with all the essential components included. The photographs of the first improved M1A2 SEP v.4 reveal some of the vehicle’s characteristics. The project intends to install new units and replace some existing ones. It included expanding the concepts included in the preceding SEP v.3 tank. Previously, the Pentagon defined the primary objectives of the SEP v.4 project and outlined how the modernized tank would differ from its predecessors. Markings on M1A2 SEP v.4 Tank prototype, Image: US Army New Traits The tank has so far only been seen from the front and the right. On other structural parts, the letters “PV05 SEPV4” are present.

The markings “M1A2 SEP v.4” are affixed on the tank’s side screens. The public photographs show the latest Abrams tank in an unconventional layout with several new components. Reports state that the tankers from the 2nd Battalion have arrived at the Yuma training site (Arizona) and are now engaged in testing the improved M1A2 SEP v.4 tank. On October 6, the 2nd Battalion, 12th Cavalry Regiment of the 1st Cavalry Division of the United States Army uploaded a few images from recent training and testing activities on its Social Media channels.

The prototype was expected to be designed and tested in the fiscal year 2022, but the project is somewhat behind schedule owing to several obstacles. The modernization project M1A2 SEP v.4 (System Enhancement Package version 4) was developed over several years to enhance the existing tank.
