Hellfire Height of Burst (HOB) Sensor (Army)
Abstract
The Hellfire Height of Burst Sensor is a miniaturized radio frequency (RF) or laser based target detection device that will be integrated into the new Electronic Safe and Arm Device (ESAD) being incorporated into the next generation Hellfire missile (Hellfire R). The HOB sensor provides for improved lethality against targets in the open by detonating the warhead at a height above ground optimized for these targets. This TTl project funds the final design and engineering of the HOB sensor optimized for Hellfire, provides component and system level environmental and hardware-in-the-loop testing, and allows two flight tests of HOB sensor equipped missiles. Program Outputs and Efficiencies: HOB sensor for the Hellfire AGM-114R missile. The HOB sensor will be integrated into the Hellfire missile and undergo hardware-in-the-loop, environmental, and flight testing as part of the TTl effort. The final outcome will be two missile flights incorporating the HOB sensor. The first flight will replace the warhead with a telemetry package to record the missile flight data as well as the point at which the HOB sensor triggers the warhead. The second flight will incorporate both the HOB sensor and the Hellfire warhead. Lethality data will be collected to validate the modeled performance against targets in the open. Simulation has shown that the HOB sensor will significantly increase the lethality when fired from platforms that allow a steep angle of impact. The Technology Transition Initiative accelerates the transition of this caplability by two years.
