Lightweight Handheld Mortar Ballistic Computer


Speed, agility, accuracy, clear communications—these are keys to success in almost any endeavor and particularly so on the battlefield. The ability to fire quickly and accurately and then move to another location is critical to improving the safety of America’s troops.


In conjunction with the U.S. Army Armament Research, Development and Engineering Center (ARDEC), Engility has helped create the Lightweight Handheld Mortar Ballistic Computer (LHMBC) system. Run on ruggedized, handheld personal digital assistants (PDAs), the LHMBC has been fielded in Iraq and Afghanistan. Engility has played a critical role on the LHMBC team. Engility team members have contributed to engineering decisions that have maximized the LHMBC’s performance. These contributions include developing database interfaces and digital communications systems as well as optimizing software to meet critical time requirements. Engility personnel have also been the main developers of the peripheral interface system, which allows the software to receive data from external devices.


America’s soldiers can now set up and calculate a fire control solution, fire, and begin redeployment in under one minute—all this while maintaining real-time communication with their command center. The LHMBC is a superior system and a first of its kind with global positioning system (GPS) and digital communication capabilities. The LHMBC program has received two prominent awards. It was named one of the “Top 10 Greatest Army Inventions of 2004” and one of DoD’s “Top 5 Programs.”
