From the Background: "The Armored Multi-Purpose Vehicle (AMPV) is the replacement for the M113 Family of Vehicles (FoV) within the Armored Brigade Combat Team (ABCT), comprising approximately 30% of its tracked vehicle fleet. [...] The AMPV is currently being produced by BAE [British Aerospace] Systems in York, PA. On January 25, 2019, the AMPVentered the low-rate initial production phase. The Army planned for acquiring a total of 2,907 AMPVs, with initial vehicle delivery in 2020. The current AMPV program plans to replace 2,897 M113 vehicles at the brigade and below level within the ABCT. There are an additional 1,922 M113s supporting non-ABCT affiliated units (referred to as Echelons Above Brigade [EAB] units) that are not included in the Army's modernization plan. A full-rate production (FRP) decision is planned for the third quarter of FY2022."
