Army's Optionally Manned Fighting Vehicle (OMFV) Program: Background and Issues for Congress [Updated July 27, 2021] [open pdf - 1MB]
From the Summary: "In June 2018, in part due to congressional concerns, the Army announced a new modernization strategy and designated the Next Generation Combat Vehicle (NGCV) as the program to replace the M-2 Bradley. In October 2018, Army leadership decided to redesignate the NGCV as the Optionally Manned Fighting Vehicle (OMFV) and to add additional vehicle programs to what would be called the NGCV Program. The M-2 Bradley, which has been in service since 1981, is an Infantry Fighting Vehicle (IFV) used to transport infantry on the battlefield and provide fire support to dismounted troops and suppress or destroy enemy fighting vehicles. Updated numerous times since its introduction, the M-2 Bradley is widely considered to have reached the technological limits of its capacity to accommodate new electronics, armor, and defense systems. Two past efforts to replace the M-2 Bradley--the Future Combat System (FCS) Program and the Ground Combat Vehicle (GCV) Program--were cancelled for programmatic and cost-associated reasons. [...] On July 23, 2021, the Army reportedly selected five companies to participate in the OMFV Concept Design Phase--American Rheinmetall, BAE [British Aerospace] Systems, General Dynamics Land Systems, Oshkosh Defense, and Point Blank Enterprises. The Army's FY2022 OMFV Research, Development, Test, and Evaluation (RDT&E) budget request is $225.106 million. Potential issues for Congress include oversight of the Army's OMFV acquisition strategy and OMFV program decisionmaking authority."
