M1 Abrams tanks progress towards new enhancement package

07 September 2017

General Dynamics Land Systems (GDLS) and the US Army are progressing with two upgrade efforts for M1 Abrams main battle tanks (MBTs), including prototype work towards a new enhancement package.

The company was awarded a contract to design, develop, and integrate “multiple engineering changes into the Abrams M1A2 System Enhancement Package Version 3 (SEPv3), creating a SEPv4 and further modernising the tanks”, it announced.

The SEPv4 configuration realises updates formulated under a so-called Engineer Change Proposal 1B (ECP1B), and this focuses on lethality and adds a commander’s primary sight (formerly known as the commander’s independent thermal viewer), an improved gunner’s primary sight, and the ability to fire the 120 mm advanced multipurpose tank round that merges several capabilities into a single round.
