Editing M1 Abrams (section)

===Future plans===
During the 1980s and 1990s, the [[Armored Systems Modernization#Block III tank|Block III]] main battle tank from the [[Armored Systems Modernization]] (ASM) program was expected to succeed the M1 Abrams family in the 1990s. The design had an unmanned turret with a 140&nbsp;mm main gun, as well as improved protection. The end of Cold War hostilities caused the end of the program. The tracked [[M8 Armored Gun System]] was conceived as a possible supplement for the Abrams in U.S. service for low-intensity conflict in the early 1990s. Prototypes were made but the program was canceled. The eight-wheeled [[M1128 mobile gun system]] was designed to supplement the Abrams in U.S. service for low-intensity conflicts.<ref name=replace>{{cite book |title=Asia-Pacific Defence Reporter |volume= 30 |year=2004 |publisher=Asia-Pacific Defence Publications |url= https://books.google.com/books?id=gEG6AAAAIAAJ |access-date=2 April 2011 |archive-date=14 January 2023 |archive-url= https://web.archive.org/web/20230114043818/https://books.google.com/books?id=gEG6AAAAIAAJ |url-status=live}}</ref> It has been introduced into service and serves with Stryker brigades.

Engineering Change Proposal 1 is a two-part upgrade process. ECP1A adds space, weight, and power improvements and active protection against [[improvised explosive device]]s. Nine ECP1A prototypes have been produced as of October 2014. ECP1B, which would begin development in 2015, may include sensor upgrades and converging several tank round capabilities into a multipurpose round.<ref name="ECP1A AUSA">{{cite news|last1=Wasserbly|first1=Daniel|title= AUSA 2014: Army outlines upcoming combat vehicle choices |url= http://www.janes.com/article/44473/ausa-2014-army-outlines-upcoming-combat-vehicle-choices|work=IHS Jane's International Defence Review |date=14 October 2014|quote=ECP1A for Abrams, which just completed a "critical design review", and includes design efforts to incorporate data links for future ammunition, increased protection, as well as on-board diagnostics and a shift from line replaceable units (LRUs) to line replaceable modules (LRMs). LRMs are easier to replace because there are fewer cables, boxes, and cards to handle. |url-status= live|archive-url= https://web.archive.org/web/20150429105740/http://www.janes.com/article/44473/ausa-2014-army-outlines-upcoming-combat-vehicle-choices|archive-date=29 April 2015}}</ref>
