M870A2E1 MEDIUM HEAVY EQUIPMENT TRANSPORTER (MHET).

The M870A2E1, fielded in April 2004, is a 50-ton payload, three axle Medium Heavy Equipment Transporter (MHET) based on the M870A2 MEDIUM HEAVY EQUIPMENT TRANSPORTER (MHET) but with changes to increase its capacity:

  • Modified to transport wider/heavier loads (50-ton capacity)
  • Removable, hydraulically operated gooseneck for the front loading of equipment
  • "D" ring tie downs and folding outriggers for wide loads.

The M870A2E1 changes enable it to carry wider loads such as the M621B Scraper and Assault Amphibious Vehicles (AAV). At the time the M870A2E1 entered the Marine Corps fleet in 2004, the LVS MK48/16 prime mover with the M870A2E1 trailer was the largest motor vehicle in the Marine Corps.
