Advanced Precision Kill Weapon System
The Advanced Precision Kill Weapon System (APKWS) is a kit that equips Hydra 70 unguided rockets with laser guidance and turns them into precision-guided munitions (PGMs). The weapon bridges the gap between the Hydra 70 and AGM-114 Hellfire systems, providing a cheaper way to hit lightly armored targets.
