-In 2019, the Army completed Phase I live fire testing of the Bradley Fighting Vehicle Systems (BFVS) Engineering Change Proposal (ECP) to evaluate the effect of these changes on the survivability of the Bradley to combat engagement‑induced ballistic shock and underbody accelerative loads.
-Preliminary analysis of Phase I live fire testing did not reveal any significant or unexpected vulnerabilities.
-The Army is on schedule to complete the Phase II Full‑Up System-Level (FUSL) live fire test events using a production‑representative Bradley vehicle in FY21.
-DOT&E will complete a detailed survivability analysis to support the Bradley A4 Early Fielding Decision in FY21.
...
The current plan is to convert four brigades to the A4 variant and supply the European Deterrence Initiative with one brigade set of A4 vehicles.
...
The Bradley ECP LFT&E program consists of two phases. Phase I included system-level tests using prototype vehicles while Phase II will focus on FUSL events using production‑representative vehicles. The Army completed Phase I testing in FY19 and is scheduled to complete Phase II testing in FY21.
...
Phase I live fire testing, performed from June 2018 to September 2018, included two shaped-charge jet test events, one thermobaric warhead test event, and two IED/mine engagement tests.

-Upon completion of a Limited User Test (LUT) in September 2018, the Army approved Milestone C and the Armored Multi‑Purpose Vehicle (AMPV) program entered into low-rate initial production (LRIP).
-The Program Office identified several engineering and design fixes to address the deficiencies identified during the LUT.
-Production delays and quality challenges from the BAE plant in York, Pennsylvania, affect the test schedule and may cause a delay of the IOT&E scheduled for 3QFY21.
-In FY19, the Army completed Phase I system-level live fire testing of the AMPV General Purpose (GP) and Mortar Carrier (MC) variants to assess survivability and force protection specification requirements. Live fire testing will continue through 3QFY21 for all AMPV variants.
...
The program entered into LRIP in January 2019, with the first LRIP vehicle expected delivery in March 2020.
...
DOT&E will provide a comprehensive classified AMPV survivability LFT&E report to support the Full-Rate Production decision in FY22
