M577A3 Command Post Carrier

M577A3 Command Post CarrierThe M577A3 Tracked Command Post Carriers are full-tracked lightweight vehicles used as an operational staff office and command post. The M577A3 incorporates the RISE powerpack and improved driver controls.

The vehicle is C130 air transportable, however it is not air droppable.

Additional materiel changes, outside of the A3 RISE Block Modifications, could also be applied to the M577. PM-M113's intention is to block the materiel changes as funding becomes available.

5 KW APU Fuel Lines This M577 change allows replacement of the 4.2 KW gasoline powered auxiliary power unit (APU) on the M577A2 with the 5 KW diesel powered APU.

Other M577 changes could include:

The XM577A4 Stretch has an interior volume of 502 cubic feet (an increase of 108 cubic feet) and a payload capacity of over 5000 pounds, making it equivalent in capacity to the S-280 tactical shelter. The XM577A4 Stretch Armored Tactical Command and Control System is a prototype Stretch version of the M577A3 Armored Command Post. By using the RISE power package, the vehicle incorporates a sixth road wheel and longer hull to provide more interior space and increased payload capacity.The XM577A4 Stretch is capable of carrying bolt-on armor as well as crew compartment spall liners for additional side and top attack protection. The XM577A4 stretch was developed by United Defense, L.P. as an Independent Research and Development program. This vehicle is currently being considered as a platform for Hazardous Material Operational Roles.
