Aerial fire-fighting bucket systems are disclosed for liquid cargo pickup, transport, and discharge. Bucket systems include a valve system disposed in the lower structure and a computer-controlled hydraulic motor/pump and accumulator configured to maintain hydraulic pressure, and controls to release liquid cargo from the bucket by a hydraulically activated valve assembly. Hydraulic accumulator charging operates independently of activation of cargo pickup, transport, and discharge cycles. Hydraulic accumulator sizing provides for a minimum of actuations of extension and retraction of the piston within a short-time interval reducing weight and electrical supply burdens on the aircraft.
