Advanced Fill Device (AFD/A)

The Advanced Fill Device (AFD/A) gives signal officers the ability to direct and deploy the distribution of communications information while supporting three types of radio distribution.

The AFD/A is used as part of the Communications Management System (CMS) to support planning and distribution of communications information. It supports hierarchical distribution of two separate frequency plans.

  • Directs the user to the equipment to be filled
  • Supports distribution of a compromise recovery plan
  • Supports 10 plan periods

Each AFD/A can distribute communications information for approximately 1,500¹ radios. The AFD/A supports three types of distribution: radio fill, key fill and net fill. It provides additional support for:

  • A purge operation allowing sensitive information to be removed from the device
  • Over-the-air erasing of the COMSEC keys of captured radios

Interoperable with the following fill equipment:

  • CMS
  • MX-18290 fill devices
  • AFD
  • PFD

Supports filling the following radios:


  • Processor: Intel® XScale® PXA270, 520 MHz
  • Operating System: Microsoft® Windows Mobile® Version 5.0, Stored in non-volatile, Secure, Flash
  • Memory (RAM): 64 MB low-power RAM databases
  • Data Storage: Stores two plans without data loss when the batteries are discharged
  • High Contrast Color Display: 3.5” diagonal (89 mm) 1/4 VGA Backlit LCD readable in direct sunlight
  • Touchscreen: Sealed, resistive, pressure sensitive touchscreen, Convenient on board stylus storage
  • Communications Module: Modular, field replaceable

    • Size: 6.5 in long x 3.5 in wide x 1.7 in thin, (165 mm long x 89 mm wide x 43 mm thin)
    • Weight: 17 ounces (482 grams)
    • Magnesium case with elastomer overmold
  • Keyboard: LED backlit keys including a four-way directional button
  • Environmental:
    • MIL-STD-810F: water, humidity, sand and dust, vibration, altitude, shock high temperature, low temperature, temperature shock
    • Waterproof and dustproof, IP67
    • Shockproof: multiple drops from 5 ft (1.5 m) onto concrete
  • Power:
    • Operates for more than 20 hours on one charge
    • Battery easily changed in the field without tools
    • Power off mode extends battery during long periods of inactivity

¹ The maximum number of radios is dependent upon the information associated with each radio.
