Lockheed Martin Offers RuBee Solution for Monitoring Munitions

The tags and readers, provided by Visible Assets Inc., can be used to identify and track a variety of sensitive items, including fused ordnances, firearms, night-vision goggles and flak jackets.

Lockheed Martin's Information Systems and Global Solutions (IS&GS) division has begun marketing a solution for government agencies that can detect the movement and, in some cases, condition and operation of weapons and ammunition. Lockheed Martin IS&GS is offering the solution, known as the RuBee Sensitive Item Warehouse system—manufactured and previously sold by Visible Assets Inc. (VAI)—for its customers at several U.S. and international government agencies. Lockheed Martin will provide installation, integration and enterprise-level management of the technology, as part of the company's Global C4ISR portfolio of products. (C4ISR is a military term, derived from the words "Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance.")

Lockheed Martin is currently in discussions with an armory that services the U.S. Department of Energy (DOE), to install the technology at that armory and thereby track the movements of weapons, with the goal of expanding the system to other armories throughout the DOE. Four DOE sites have been utilizing the RuBee-based weapons-tracking solution provided by VAI, including one deployed in Texas in 2011 (see Pantex Nuclear Weapons Plant Adopts RuBee RFID to Track Tools, Chemicals). Lockheed Martin is conducting a pilot for the U.S. Department of Defense (DOD), and expects to complete that deployment later this year, according to David Weber, Lockheed Martin IS&GS' business-development manager for C4ISR. For the DOD deployment, Lockheed is serving as the prime contractor, with VAI acting as the subcontractor. The intention, Weber says, will be to expand the solution's use, thereby managing the complete arsenal of weapons for the DOD customer, which has asked to remain unnamed.

Lockheed Martin's RuBee asset tag is 0.77 inch by 1.9 inches by 0.45 inch in size.
The technology that Lockheed Martin is marketing complies with the RuBee standard (IEEE 1902.1). The company's RuBee MIL STD 810G battery-powered tags are designed to be attached to weapons and receivers that capture an item's ID number and forward that information to software. RuBee tags can be the technology of choice for munitions tracking by government agencies, Weber explains, since it transmits a 132 kHz low-frequency (LF) signal that relies primarily on the magnetic portion of an electromagnetic wave, rather than the electronic component. Such a signal, Lockheed Martin reports, operates well within metal and liquid environments, and is intrinsically safe near explosives and fused ordnances. What's more, VAI adds, the very low frequency makes a RuBee transmission safer from eavesdropping and does not pose a target risk, since it will not leak out of a building.

The Allegro Armory 20/20 solution can also include steel smart racks installed with a RuBee reader and antennas as required for each specific customer and use case. The readers are powered by an Ethernet connection, with data related to those reads managed by VAI's Dot-Tag Visibility Server software. When weapons or other items stored on the shelves are needed, staff members enter and exit the armory by scanning a bar code or a magnetic stripe on their ID badges (or, in some cases, workers carry RuBee tags). That badge ID is then linked to the ID number of the munitions that are detected to be removed.

For weapons, in most cases, tags are either incorporated into a standard grip or attached on a barrel. Tagging the weapons enables them to be identified not only by a smart rack, but also by a VAI pRap handheld reader or a RuBee DoorGuard or GateReader.

With the weapons shot counter (WSC) functionality, the technology also comes with an accelerometer linked to the munitions item's tag. That sensor enables the system to track the number of times the weapon is used, and to determine the barrel temperature based on that data.
