TOW Integrated Master Battery (IMB)

The TOW M220 system is a highly sought-after legacy anti-armor weapon system due to its ruggedness, reliability and lethality. Partnering with the U.S. Army and Defense Logistics Agency, HII developed the Integrated Master Battery (IMB) to address the challenge of supporting Foreign Military Sales (FMS) systems facing obsolescence issues.

Approved by the U.S. Army, the maintenance-free TOW IMB consolidates the functions of eight current TOW M220 power and maintenance components needed for operation into a single unit, reducing the system size and weight from 160 pounds to 18 pounds.

The high-capacity energy storage design enables an increase in operational time, silent watch and missile fires compared to the legacy battery.

TOW IMB provides a condensed operational footprint and reduces battery subsystem procurement and operational and logistics support costs. The design also incorporates new conditioned-based maintenance features such as status of battery charge, low battery charge alert, and low voltage condition alert.

The IMB replaces two battery assemblies, the TOW Vehicle Power Conditioner (TVPC), the MGS Battery Charger and associated monitoring unit, the Night Sight’s Vehicle Power Conditioner (VPC), the Battery Power Conditioner (BPC) and associated consumable battery assemblies, and the BPC spare battery case.
