Analyst Note:
This image shows the pneumatic accumulator, or ‘accumulator bottle’, of the AGM-114R9X missile. The accumulator bottle stores gas that is used to actuate the fins, adjusting the trajectory of the missile in flight. All AGM-114 Hellfire-series missiles have an accumulator bottle. The accumulator bottle is a fragment that often survives intact, even in Hellfire missile variants that carry an explosive payload. (ARES)
