Ultralife Corporation (NASDAQ: ULBI) has received a contract valued at approximately $5.5 million to supply its suite of Land Warrior Lithium non-rechargeable batteries and rechargeable Lithium Ion batteries and charging systems from a major international defense contractor for use with the Land 200 Battle Management System by the Australian military. Deliveries are expected to begin in the first quarter of 2011 and be completed by the fourth quarter of 2012.

“Our capabilities in developing and supplying technically-advanced defense communications and power systems, which we have demonstrated to the U.S. Department of Defense across a wide variety of military programs, are increasingly being recognized by our international allies,” said John D. Kavazanjian, president and chief executive officer. “In this case, our Land Warrior product suite will be used to support the Australian military’s Land 200 Battle Management System, a program for which we are already supplying our A320 RF pocket amplifiers.”

Land Warrior is an integrated, modular fighting system that uses technology to enhance individual soldiers’ close-combat tactical awareness, lethality and survivability. The system includes weapon-mounted sensors, an integrated helmet assembly, a communications-navigation computer system and software for friendly-force tracking and command/control programs, and it incorporates Ultralife’s battery models LI-145, LI-80, LM-145 and CH0006 Charger and Adapters.
