The Army's Armored Multi-Purpose Vehicle (AMPV)


Bacg round
The Army  Armored Multi-Purpose Vehicle (AMPV)  is

    the replacement for the M113 family of vehicles
    within  the Armored   Brigade  Combat Team
    [ABCT],  comprising approximately 30 percent of
    its tracked vehicle fleet. The Army's worldwide
    fleet of AMPVs will include nearly 3,000 vehicles
    delivered within the next 20 years.
There are five planned AMPV variants:

    The  M1283 General Purpose (GP) variant
    [Figure 1] provides protected maneuver for soldiers
    alongside ABCT  combat  vehicles during tactical
    operations and provides support to the infantry
    squad during mounted/dismounted  assault during
    tactical operations. The GP variant accommodates
    two crew and four Soldiers and is reconfigurable to
    carry one litter.
    The M1284  Medical  Evacuation variant supports
    the ABCT integration   of medical support and
    [casualty evacuation] CASEVAC  as an integrated
    part of the networked combat forward formation,
    enhancing the organic medics who ride with and
    accompany   cavalry units during mounted  and
    dismounted operations. Crew capacity is for three
    crew   members,   and  a  reconfigurable crew
    compartment   that  accommodates   four  litter
    casualties, six ambulatory (sitting) casualties, or a
    combination of two  litter and three ambulatory
    casualties.
    The  M1285   Medical  Treatment  (MT)  variant
    integrates advanced medical treatment in a mobile
    surgery suite to the ABCT. The MT hosts four crew
    members,  which includes a medic and physician
    Assistant or unit surgeon, and a treatment table that
    can serve to carry one litter patient. The vehicle also
    hosts the capability for onboard medical equipment
    for casualty care.
    The M1286   Mission Command [MCmd] variant
    ... takes advantage of increased size, weight, power
    and cooling, and provides a significant increase in
    command,   control, computers, communications,
    cyber, intelligence, surveillance and reconnaissance
    capability. The variant accommodates two crew
    members,  and three workstation operators, and its
    hosted network provides full tactical command post
    capabilities at brigade and battalion levels.
    The  M1287   Mortar   Carrier  (MC)   provides
    immediate, responsive, heavy mortar fire support to


    the ABCT  in the conduct of fast paced offensive
    operations by utilizing the M121 Mortar System
    and M95  Mortar  Fire Control System. The MC
    variant accommodates four Soldiers, one vehicle
    crew member  and three mortar crew members.

Prograr Activities
The AMPV   is produced by BAE Systems in York, PA. On
January 25, 2019, the AMPV entered the low-rate initial
production (LRIP) phase. The Army originally planned for
acquiring a total of 2,907 AMPVs, with initial vehicle
delivery in 2020. The AMPV program plans to replace
2,897 M-113 vehicles at the brigade and below level within
the ABCT.


  Low-Rate Initial Production (LRIP) is a programmatic
  decision made when manufacturing development is completed
  and there is an ability to produce a small-quantity set of
  articles. It establishes an initial production base and sets the
  stage for a gradual increase in the production rate to allow for
  full-rate production (FRP) on completion of Operational Test
  and Evaluation.
  FRP is a decision made allowing for government contracting
  for economic production quantities following stabilization of
  the system design and validation of the production process.
