Army Moves STUB Standard Batteries Into Manufacturing, Showcases Rifle Integration

The effort aims to simplify resupply by using a single interface across eight sizes for soldier devices.

Overview

  • The C5ISR Center says prototypes have entered a manufacturing phase that enables acquisition partners to procure and integrate the batteries into fielded systems.
  • Images from Aberdeen Proving Ground show an M7 rifle with a buttstock STUB interface powering an XM157 fire-control optic and a thermal clip-on sight.
  • Officials say standardization reduces the number of battery types soldiers carry and could enable charging at observation posts instead of frequent resupply.
  • The C5ISR Center is partnering with DEVCOM’s Armaments Center, Army Research Laboratory and Soldier Center to mature designs and accelerate integration.
  • Adoption is guided by MIL-STD-3078 and battery.army.mil, while a Powered Weapon Demonstrator and PM Soldier Lethality reviews chart the path for broader weapon integration.
