Unveiling the Reaper: A Look Under the Hood

This video segment pulls back the curtain on the MQ-9 Reaper's complex systems. While the Reaper may appear streamlined from afar, the drone's functionality relies on a coordinated network of components, from the launch crew to the ground control station, and the diverse weaponry it carries. The discussion delves into the specific technology integrated into the aircraft for navigation, surveillance, and precision targeting, allowing the viewer to understand how this technology is used to achieve missions, including the advanced Ninja Missile. The core systems that define the Reaper's capabilities are carefully explained.

• The Reaper uses an angle of attack sensor which is key to understanding airflow and stability, which is combined with GPS modules for navigation.
• The Lynx SAR radar functions as a high-powered radar camera, creating detailed pictures even in poor weather, this radar is key to a series of sensors that make up the MQ9, including the Satcon dish that allows for communication beyond the operator's line of sight, and infrared sensors that detect thermal signatures.
• The Reaper carries the AGM Hellfire Missile, effective against a variety of targets, which can be locked on using laser, radar, or GPS guidance and reaches speeds over 950mph when fired. But perhaps the most interesting component is the "Ninja Missile" (AGM-114 R9X), where a traditional warhead is replaced with six extendable blades, creating a 3-foot kill zone, designed to minimize collateral damage.
