HALO

BAE Systems' Hostile Artillery Locating System (HALO) is a counter battery/force protection system that uses sophisticated acoustic detection technology to identify enemy artillery sources, to locate explosions and to detect any hostile firing near to friendly forces. The British Army deployed HALO in three countries where the system performed as planned demonstrating its capabilities. The three countries involved in the system demonstration were Bosnia and Kosovo, Afghanistan and Iraq and the HALO was demonstrated over there at warfare/peacekeeping conditions. HALO uses passive acoustic technology to locate hostile attacks at both short and long ranges, with conventional and unconventional weapons. It uses an array of sensor posts deployed all along a large area. The sensor posts are redundant so one or more of them might be destroyed without compromising HALO functionality. Moreover, the system is ready 24 hours at day/nigh and all-weather conditions while providing early warning against hostile targets and target acquisition. Once located, HALO transmits the enemy artillery location data to counter fire units to precisely engage and destroy the threat. BAE Systems claims that HALO can operate for thousands of hours without a break. Typically, the HALO system is accurate to 50-100 meters at ranges of 10 kilometers. In combat, HALO demonstrated being effective at locating hostile artillery up to 56 kilometers away. It provides accurate battlefield coverage over large areas (approx. 2,000 square kilometers) even in mountainous, urban and flat terrain. In fact, British Army officials deemed HALO to be more effective than counter battery radar systems in peacekeeping operations.
